November 1996 P/N 85001 Safety Instructions When Using Your Computer System As you use your computer system, observe the following safety guidelines: • To help avoid damaging your computer, be sure the voltage selection switch on the power supply is set to match the alternating current (AC) power available at your location: — 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as Japan, South Korea, and Taiwan • Do not push any objects into the openings of your computer. Doing so can cause fire or electric shock by shorting out interior components. • Keep your computer away from radiators and heat sources. Also, do not block cooling vents. Avoid placing loose papers underneath your computer; do not place your computer in a closed-in wall unit or on a bed, sofa, or rug. Ergonomic Computing Habits — 230 V/50 Hz in most of Europe, the Middle East, and the Far East Also be sure your monitor and attached peripherals are electrically rated to operate with the AC power available in your location. • • • • To help prevent electric shock, plug the computer and peripheral power cables into properly grounded power sources. These cables are equipped with 3-prong plugs to ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cable, use a 3-wire cable with properly grounded plugs. To help protect your computer system from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply. Be sure nothing rests on your computer system’s cables and that the cables are not located where they can be stepped on or tripped over. WARNING: Improper or prolonged keyboard use may result in injury. For comfort and efficiency, observe the following ergonomic guidelines when setting up and using your computer system: • Position your system so that the monitor and keyboard are directly in front of you as you work. Special shelves are available (from Dell and other sources) to help you correctly position your keyboard. • Set the monitor at a comfortable viewing distance (usually 510 to 610 millimeters [20 to 24 inches] from your eyes). • Make sure the monitor screen is at eye level or slightly lower when you are sitting in front of the monitor. • Adjust the tilt of the monitor, its contrast and brightness settings, and the lighting around you (such as overhead lights, desk lamps, and the curtains or blinds on nearby windows) to minimize reflections and glare on the monitor screen. • Use a chair that provides good lower back support. Do not spill food or liquids on your computer. If the computer gets wet, consult your Diagnostics and Troubleshooting Guide. iii • Keep your forearms horizontal with your wrists in a neutral, comfortable position while using the keyboard or mouse. • Always leave space to rest your hands while using the keyboard or mouse. • • Let your upper arms hang naturally at your sides. Sit erect, with your feet resting on the floor and your thighs level. • When sitting, make sure the weight of your legs is on your feet and not on the front of your chair seat. Adjust your chair’s height or use a footrest, if necessary, to maintain proper posture. • Vary your work activities. Try to organize your work so that you do not have to type for more than a minute or so at a time without stopping. When you stop typing, try to do things that use both hands. monitor screen at eye level wrists relaxed and flat monitor and keyboard positioned directly in front of user arms at desk level feet flat on the floor iv When Working Inside Your Computer Before you remove the computer cover, perform the following steps in the sequence indicated: 1. Turn off your computer and any peripherals. 2. Disconnect your computer and peripherals from their power sources. Also disconnect any telephone or telecommunications lines from the computer. 3. Protecting Against Electrostatic Discharge Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity from your body before you touch any of your computer’s electronic components, such as the microprocessor. You can do so by touching an unpainted metal surface on the computer chassis. Doing so reduces the potential for personal injury or shock. As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your body may have accumulated. Touch an unpainted metal surface at the back of the computer chassis (such as the power supply) before touching anything inside your computer. In addition to the preceding precautions, you can also take the following steps to prevent damage from electrostatic discharge (ESD): While you work, periodically touch an unpainted metal surface on the computer chassis to dissipate any static electricity that might harm internal components. • When unpacking a static-sensitive component from its shipping carton, do not remove the component’s antistatic packing material until you are ready to install the component in your computer. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body. • When transporting a sensitive component, first place it in an antistatic container or packaging. • Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads. In addition, take note of these safety guidelines when appropriate: • • Do not attempt to service the computer system yourself, except as explained in this guide and elsewhere in Dell documentation. Always follow installation and servicing instructions closely. When removing a component from the system board or disconnecting a peripheral device from the computer, wait 5 seconds after turning off the system before removing the component or disconnecting the device to avoid possible damage to the system board. • When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, make sure both connectors are correctly oriented and aligned. • Handle components and cards with care. Don’t touch the components or contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a component such as a microprocessor chip by its edges, not by its pins. The following caution appears throughout this document to remind you of these precautions: CAUTION: See “Protecting Against Electrostatic Discharge” in the safety instructions at the front of this guide. v vi Preface About This Guide This guide is intended for anyone who uses the Dell PowerEdge 2100/180 or 2100/200 computer systems.

Front Panel Connecting External Devices You can connect various external devices, such as a mouse and printer, to the I/O ports and connectors on the computer’s back panel. The system BIOS detects the presence of external devices when you boot or reboot your system. When connecting external devices to your computer, follow these guidelines: • Check the documentation that accompanied the device for specific installation and configuration instructions. For example, most devices must be connected to a particular I/O port or connector to operate properly. Also, external devices like a mouse or printer usually require you to load software files called device drivers into memory before they will work. These software drivers help the computer recognize an external device and direct its operation. Device drivers of this type are normally included with your operating system software. Introduction 1-13 • Always attach external devices while your computer is turned off. Then turn on any external devices before turning on the computer unless the documentation for the device specifies otherwise. (If the computer does not seem to recognize the device, try turning on the computer before turning on the device.) For information about enabling, disabling, or configuring I/O ports and connectors, see Chapter 4, “Using the System Setup Program,” or Chapter 5, “Using the EISA Configuration Utility.” For detailed descriptions and illustrations of each port and connector on the I/O panel, see “I/O Ports and Connectors” in Appendix B. key Preventing Unauthorized Access Inside the Computer To prevent unauthorized access to the inside of the computer, you can replace one of the screws that secure the cover to the chassis with a special keylock screw that is included with the system.

After you boot the system with the system utility diskette, you can use the Asset Tag utility to enter an asset tag number that you or your organization assign to the computer. You can also use the Asset Tag utility to reenter the computer’s service tag number if that becomes necessary. You can view the asset tag number using the System Setup program as described in Chapter 4, “Using the System Setup Program.” Assigning and Deleting an Asset Tag Number An asset tag number can have up to ten characters; any combination of characters, excluding spaces, is valid. To assign or change an asset tag number, type asset and a space followed by the new number; then press <Enter>. For example, type the following command line and press <Enter>: asset 1234567890 When prompted to verify the asset tag number, type y and press <Enter>. The system then displays the new or modified asset tag number and the service tag number. To delete the asset tag number without assigning a new one, type asset /d and press <Enter>. Table 2-1 lists the command line options you can use with the Asset Tag utility. To use one of these options, type asset and a space followed by the option. . Table 2-1.

These device drivers are designed to work with the Adaptec AIC-7880 Ultra/Wide SCSI controller chip on the system board. The readme.txt file that is included with your SCSI device drivers (in the \scsi directory on the CD) provides updates to the information in this chapter. Both the built-in AIC-7880 and the optional AHA-2940UW SCSI controller card are all part of the Adaptec 78xx series of SCSI controllers, and use the 78xx series of SCSI drivers Dell provides. The Adaptec SCSI basic input/output system (BIOS), which is stored in your computer system’s flash memory or on the optional AHA-2940UW SCSI controller card, links these SCSI device drivers to the built-in AIC-7880 or the optional AHA-2940UW SCSI controller card. For instructions on installing SCSI hardware devices such as hard-disk drives, tape drives, or CD-ROM drives, see Chapter 8, “Installing Drives in the External Bays,” and Chapter 9, “Installing Drives in the Internal Bays.” For information on SCSI configuration guidelines (SCSI identification [ID] numbers and termination requirements), see “SCSI Configuration Guidelines” in Chapter 9. After the SCSI devices you plan to use are installed, you may need to install and configure one or more SCSI device drivers so that your SCSI devices can communicate with your operating system. SCSI device drivers are provided for the following operating systems: • • Microsoft Windows NT Server 3.51 Novell NetWare 3.12 and 4.x See Chapter 2, “Using the Dell Server Assistant CD,” for instructions on creating a diskette of drivers for your operating system. For instructions on configuring the SCSI device drivers, see the appropriate sections in this chapter. Use the editor included with your operating system to view or print the readme.txt file or any other readme file. The SCSISelect Utility The BIOS for the built-in Adaptec AIC-7880 controller includes the menu-driven SCSISelect configuration utility, which allows you to change SCSI controller settings without opening the computer. SCSISelect also contains SCSI disk utilities that let you low-level format or verify the disk media of your SCSI hard-disk drives. SCSISelect Default Settings Default settings for the optional Adaptec AHA-2940UW SCSI controller and the built-in AIC-7880 SCSI controller are shown in Table 3-1. These default settings are appropriate for most Peripheral Component Interconnect (PCI) systems. Run SCSISelect only if you need to change any of the default settings. NOTE: The term host adapter is used throughout this chapter to refer to the built-in AIC-7880 SCSI controller or the optional AHA-2940UW SCSI controller card. For situations in which you might want or need to change the settings, see the descriptions of each setting in the following subsections. To change any of the default settings or to format or verify a disk, see “Starting the SCSISelect Utility” found later in this chapter. Installing and Configuring SCSI Drivers 3-21 Table 3-1. Default SCSI Controller Settings Setting Default SCSI Bus Interface Definitions: Host Adapter SCSI ID 7 SCSI Parity Checking Enabled Host Adapter SCSI Termination Low On/High On Boot Device Options: Boot Target ID 0 Boot LUN Number 0 Basic Host Adapter Settings The basic host adapter settings are the SCSISelect settings most likely to require modification. • Host Adapter SCSI ID. This option sets the host adapter’s SCSI ID. The default setting is SCSI ID 7, which allows the host adapter to support narrow SCSI devices in addition to wide SCSI devices. Dell recommends that you leave the host adapter set to SCSI ID 7. • SCSI Parity Checking. This option determines whether the host adapter verifies the accuracy of data transfer on the SCSI bus. The default setting is Enabled. You should disable SCSI Parity Checking if any SCSI device connected to the host adapter does not support SCSI parity; otherwise, leave it enabled. Most SCSI devices support SCSI parity. If you are unsure if a device supports SCSI parity, consult the documentation for the device. • Host Adapter SCSI Termination. This option sets termination on the host adapter. The default setting for all Adaptec 78xx series host adapters is Low On/ High On. Dell recommends that you leave this option set to the default. SCSI Device/Configuration: Initiate Sync Negotiation Yes (Enabled) Maximum Sync Transfer Rate 40 Mb/sec Enable Disconnection Yes (Enabled) Initiate Wide Negotiation Yes (Enabled) Send Start Unit Command Yes (Enabled) Advanced Host Adapter: Boot Device Settings Host Adapter BIOS Enabled Support Removable Disks Under BIOS as Fixed Disks Boot Only Extended BIOS Translation for DOS Drivers > 1 GB Enabled Display <Ctrl><a> Message During BIOS Initialization Enabled Multiple LUN Support Disabled BIOS Support for Bootable CD-ROM Enabled BIOS Support for INT 13 Extensions Enabled Support for Ultra SCSI Speed Enabled The boot device settings allow you to specify the device from which to boot your computer. • Boot Target ID. This option specifies the SCSI ID of the device from which you wish to boot your system. The default setting is SCSI ID 0. The SCSI ID selected here must correspond to the ID configured on the boot device. • Boot LUN Number. If your boot device has multiple logical unit numbers (LUNs) and Multiple LUN Support is enabled (see “Advanced Host Adapter Settings” found later in this section), this option allows you to specify a particular LUN from which to boot on your boot device. The default setting is LUN 0. NOTE: For the full name of an abbreviation or acronym used in this table, see the Glossary. 3-22 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide SCSI Device Settings The SCSI device settings allow you to configure certain parameters for each device on the SCSI bus. To configure a specific device, you must know the SCSI ID assigned to that device. If you are not sure of the SCSI ID, see “Using the SCSI Disk Utilities” found later in this section. • SCSI device is connected to the host adapter, set Enable Disconnection to No to achieve slightly better performance. • Initiate Sync Negotiation. This option determines whether the host adapter initiates synchronous data transfer negotiation (sync negotiation) between itself and the device. The default setting is Yes. NOTE: Some 8-bit SCSI devices may have trouble handling wide negotiation, which may result in erratic behavior or a hang condition. For these devices, set Initiate Wide Negotiation to No. The host adapter always responds to sync negotiation if the SCSI device initiates it. If neither the host adapter nor the SCSI device initiates sync negotiation, data is transferred asynchronously. When this option is set to Yes, the host adapter attempts 16-bit transfer. When this option is set to No, 8-bit data transfer is used unless the SCSI device itself requests wide negotiation. The effective transfer rate is doubled when 16-bit data transfer is used because the data path for wide SCSI is twice the size of normal 8-bit SCSI. Normally, you should leave the Initiate Sync Negotiation setting enabled, because most SCSI devices support sync negotiation and because it allows for faster data transfer. • NOTE: Some older SCSI-1 devices do not support sync negotiation. This may cause your computer to operate erratically or hang if Initiate Sync Negotiation is set to Yes. Set Initiate Sync Negotiation to No for these devices. • Enable Disconnection. This option (sometimes called disconnect/reconnect) determines whether the host adapter allows the SCSI device to disconnect from the SCSI bus. Enabling disconnection allows the host adapter to perform other operations on the SCSI bus while the SCSI device is temporarily disconnected. The default setting is Yes. Leave Enable Disconnection set to Yes if two or more SCSI devices are connected to the host adapter. This optimizes SCSI bus performance. If only one Send Start Unit Command. This option determines whether the start unit command is sent to the SCSI device at boot. The default setting is Yes. Setting this option to Yes reduces the load on your computer’s power supply by allowing the host adapter to start SCSI devices one at a time when you boot your computer. When this option is set to No, the devices are allowed to start at the same time. Most devices require you to set a jumper before they can respond to this command. Maximum Sync Transfer Rate. This option sets the maximum synchronous data transfer rate that the host adapter supports. The host adapter supports rates up to the maximum of 40 megabytes per second (MB/sec). The default setting is 40 MB/sec (the maximum). If the host adapter is set to not negotiate for synchronous data transfer, the maximum synchronous transfer rate is the maximum rate that the host adapter accepts from the device during negotiation. (This is standard SCSI protocol.) • Initiate Wide Negotiation. This option determines whether the host adapter attempts 16-bit data transfer instead of 8-bit data transfer. The default setting is Yes. NOTE: For many devices, if Send Start Unit Command is set to Yes, the boot time will vary depending on how long it takes each drive to start. Advanced Host Adapter Settings The advanced host adapter settings should not be changed unless absolutely necessary. Dell sets these values and changing them may cause conflicts with the SCSI devices. • Host Adapter BIOS. This option enables or disables the host adapter BIOS. The default setting is Enabled. NOTE: Several SCSISelect options are not valid unless the host adapter BIOS is enabled. If you are booting from a SCSI hard-disk drive connected to the host adapter, the BIOS must be enabled. Installing and Configuring SCSI Drivers 3-23 large as 8 GB under the MS-DOS operating system with a maximum partition size of 2 GB. You should disable the host adapter BIOS if the peripherals on the SCSI bus (for example, CD-ROM drives) are all controlled by device drivers and do not need the BIOS. • Extended BIOS translation is used only with MS-DOS 5.0 or later. It is not necessary to enable this if you are using another operating system such as Novell NetWare. Support Removable Disks Under BIOS as Fixed Disks. This option controls which removable-media drives are supported by the host adapter BIOS. The default setting is Boot Only. The following choices are available. CAUTION: If a removable-media SCSI device is controlled by the host adapter BIOS, do not remove the media while the drive is on or you may lose data. If you want to be able to remove media while the drive is on, install your removablemedia device driver and set this option to Disabled. When you partition a hard-disk drive larger than 1 GB, use the MS-DOS fdisk utility as you normally would. Because the cylinder size increases to 8 MB under extended translation, the partition size you choose must be a multiple of 8 MB. If you request a size that is not a multiple of 8 MB, fdisk rounds up to the nearest whole multiple of 8 MB. • Display <Ctrl><a> Message During BIOS Initialization. This option determines whether the Press <Ctrl><a> for SCSISelect (TM) Utility! message appears on your screen during system start-up. The default setting is Enabled. If this setting is disabled, you can still run the SCSISelect utility by pressing <Ctrl><a> after the host adapter BIOS banner appears. • — Disabled. No removable-media drives are treated as hard-disk drives. In this situation, software drivers are needed because the drives are not controlled by the BIOS. Multiple LUN Support. This option determines whether your system supports booting from a SCSI device that has multiple LUNs. The default setting is Disabled. Enable this option if your boot device has multiple LUNs. • Extended BIOS Translation for DOS Drives > 1 GB. This option determines whether extended translation is available for SCSI hard-disk drives with capacities greater than 1 gigabyte (GB). The default setting is Enabled. BIOS Support for Bootable CD-ROM. This option determines whether the host adapter BIOS provides support for booting from a CD-ROM drive. The default setting is Enabled. • BIOS Support for INT 13 Extensions. This option determines whether the host adapter BIOS supports disks with more than 1024 cylinders. The default setting is Enabled. • Support for ULTRA SCSI Speed. This option determines whether the host adapter supports the fast transfer rates (20.0 to 40.0 megabits per second [Mbps]). The default setting is Enabled. — Boot Only. Only the removable-media drive designated as the boot device is treated as a hard-disk drive. — All Disks. All removable-media drives supported by the BIOS are treated as hard-disk drives. • CAUTION: Back up your hard-disk drive before you change the translation scheme. All data is erased when you change from one translation scheme to another. The standard translation scheme for SCSI host adapters provides a maximum accessible capacity of 1 GB. To support hard-disk drives larger than 1 GB, the 78xx series host adapters include an extended translation scheme that supports hard-disk drives as 3-24 Starting the SCSISelect Utility You can start the SCSISelect utility by pressing <Ctrl><a> when the following prompt appears briefly at boot time: Press <Ctrl><a> for SCSISelect (TM) Utility!

Once the option is selected, SCSISelect immediately scans the SCSI bus (to determine the devices installed) and displays a list of all SCSI IDs and the devices assigned to each ID. When you select a specific ID and device, a small menu appears, displaying the Format Disk and Verify Disk Media options. • Format Disk. This option runs a utility that allows you to perform a low-level format on a hard-disk drive. Most SCSI disk drives are formatted at the factory and do not need to be formatted again. The Adaptec Format Disk utility is compatible with the vast majority of SCSI disk drives. . CAUTION: The Format Disk option destroys all data on the hard-disk drive. • Verify Disk Media. This option runs a utility that allows you to scan the media of a hard-disk drive for defects. If the utility finds bad blocks on the media, it prompts you to reassign them; if you select Yes, those blocks are no longer used. You can press <Esc> at any time to exit the utility. Exiting SCSISelect To exit SCSISelect, press <Esc> until a message prompts you to exit. (If you changed any 78xx series host adapter settings, you are prompted to save the changes before you exit.) At the prompt, select Yes to exit, and then press any Swapping a host adapter Restoring a configuration if Windows NT fails to boot Installation Overview This section provides the information needed to install and use the Dell SCSI drivers for the 78xx series of SCSI controllers with the Windows NT operating system. The Windows NT 3.51 driver diskette you create for the Microsoft Windows NT Server 3.51 operating system contains the files needed for driver installation. The \scsi subdirectory on the diskette contains the following files to be used with Windows NT 3.51: • aic78xx.sys — Adaptec’s 78xx Family driver for Windows NT • oemsetup.inf — A file used by Windows NT Setup for driver installation • readme.txt — A text file describing the Adaptec 78xx driver for Windows NT If you are performing a first-time Windows NT installation, see the following subsection, “Installing Windows NT 3.51 and the Driver,” to begin driver installation. If Windows NT is already installed in your system, see “Using Windows NT to Install or Update the Driver” found later in this section. Installing and Configuring SCSI Drivers 3-25 Installing Windows NT 3.51 and the Driver This section describes how to install the aic78xx.sys driver at the same time you install Windows NT 3.51. If Windows NT 3.51 is already installed and you wish to install or update the aic78xx.sys driver, see “Using Windows NT to Install or Update the Driver,” found later in this section. displays none. Type SCSI controllers. 7. NOTE: An older version of the aic78xx.sys driver is included in the Windows NT installation diskettes (or on the CD-ROM). To avoid loading the older driver during Windows NT installation, use the following procedure to install the new driver included on the driver diskette you create from the Dell Server Assistant CD. 1. If you choose to install Windows NT from a diskette drive, locate the Windows NT Disk 1 for Floppy Installation diskette. Make a backup copy of this diskette. If you are installing from a CD-ROM drive, locate the Windows NT Setup Disk 1 for CD-ROM Installation diskette. Make a backup copy of this diskette. Expand the list of additional SCSI controllers, select Other, and press <Enter>. The Other option is at the end of a long list of SCSI controllers and is highlighted. 8. Performing a Windows NT 3.51 Installation Follow these instructions only if you are installing Windows NT 3.51 for the first time. You can install Windows NT 3.51 from a diskette drive or from a CD-ROM drive; whichever you choose, make sure the hardware installation is completed prior to following these steps. to configure additional Insert into drive A the Windows NT 3.51 driver diskette you created, enter the following path to the installation files, and then click OK. a:\scsi 9. The screen displays the adapter drivers supported on the diskette. The Adaptec AHA-2940UW/AIC-78xx (PCI) NT 3.51 driver is highlighted by default; press <Enter> to select this driver. 10. If you want to add other SCSI controllers (not part of the Adaptec 78xx series), do so at this time by repeating steps 7 though 9 for each additional adapter, inserting the appropriate diskette provided by the hardware manufacturer. Because all Adaptec 78xx series SCSI controllers use the same driver, you configure all Adaptec SCSI controllers at the same time. 11. Press <Enter> to continue with the Windows NT operating system setup. Follow the instructions on the screen and in the Windows NT installation documentation. Performing a Windows NT 4.0 Installation 2. Put the backup diskette into drive A, and turn on your system. When prompted, insert the Windows NT Setup Disk 2 diskette. 3.

Insert the Windows NT Setup Disk 3 diskette when prompted to do so. 6. After a period of time, Windows NT Setup displays all recognized SCSI controllers. If no SCSI controllers are found, Windows NT Setup 3-26 The Windows NT 4.0 operating system has SCSI drivers for the Adaptec 78xx series of SCSI controllers integrated into the operating system. When you load the operating system software, the drivers are automatically loaded. Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Installing or Updating the Driver With Windows NT 3.51 Follow these instructions only if Windows NT 3.51 is already installed: 1. 2. Select and start the Windows NT Setup program. (Its icon is usually found in the Main program group.) There is a brief pause while Windows NT Setup scans your hardware configuration. Select the Options pull-down menu, and then select Add/Remove SCSI Adapters. The SCSI Adapter setup program displays a list of all host adapters currently installed. If you are installing the driver for the first time, skip to step 5. If you are updating the driver, continue to step 3. 3. Before you can update the driver, you must first remove the existing driver. Select the host adapter you want to remove (for example, the Adaptec AIC-78xx SCSI controller), and click Remove. When the Windows NT Setup program asks you for confirmation, click OK. Because SCSI device drivers are loaded during system start-up and because they may be needed to load Windows NT itself, the following warning message may appear: Removing SCSI Adapters may prevent Windows NT from starting correctly. 4. When you are sure you are removing the correct host adapter driver, click OK. 5. Click Add to add another host adapter type to the list. A list of additional SCSI adapters appears. 6. Expand the list of additional SCSI adapters; select Other and press <Enter>. 7. Insert the Windows NT 3.51 driver diskette you created into drive A, enter the following path to the installation files, and then click OK. a:\scsi 8. The screen displays the adapter drivers supported on the diskette. The Adaptec AHA-2940UW/AIC-78xx (PCI) NT 3.51 driver is highlighted by default; click OK. The driver is added to the list of SCSI adapters. 9. Select Adaptec AHA-2940UW/AIC-78xx (PCI) NT 3.51 from the list of SCSI adapters, and click Install. At this point, Windows NT Setup checks to see if the specified driver (aic78xx.sys) has already been copied to the hard-disk drive. 10. If the following message appears, click New to replace the existing driver and go to step 12. The driver(s) for this SCSI Adapter are already on the system. Do you want to use the currently installed driver(s) or install new one(s). If the following message appears, continue to step 11: Please <Enter> the full path to the Windows NT SCSI Adapter files. 11. Change the path to the directory with the desired device driver (for example, a:\scsi); then click Continue. The device driver is copied to your hard-disk drive and the Windows NT configuration is updated so that the new device driver loads when Windows NT reboots. 12. When the installation is complete, Windows NT Setup again displays a list of currently installed host adapter types. Verify that the new host adapter appears on the list; the string should look similar to: Adaptec AHA-2940UW/AIC-78xx (PCI) NT v3.5x 13. If you want to add other host adapters (that are not part of the Adaptec 78xx series), do so at this time by repeating steps 6 through 8 for each additional adapter, inserting the appropriate diskette provided by the hardware manufacturer. Because all Adaptec 78xx series host adapters use the same driver, you configure all Adaptec host adapters at the same time. 14. Click Close to exit the SCSI adapters portion of Windows NT Setup, and then close the program. Installing and Configuring SCSI Drivers 3-27 15. When you see the following message, click OK to exit: 5. Return to step 3 if you want to remove driver support for other types of host adapters, or click Close to exit the SCSI adapters portion of Windows NT Setup. 6. Close the Windows NT Setup program. When the following message appears, click OK to exit: The changes you have made will not take effect until the computer is restarted. If this message does not appear, no changes have been made to the Windows NT system configuration. The changes you have made will not take effect until the computer is restarted. 16. Restart your computer and Windows NT. Some drive letter assignments may have changed from the previous configuration. Removing a Host Adapter Removing a PCI expansion-card SCSI controller is as simple as physically removing it from its slot when your computer is shut down. Windows NT boots and functions properly in this configuration, but a warning message is generated every time you boot Windows NT. If this message does not appear, no changes have been made to the Windows NT system configuration. 7. Restart your computer. NOTE: The Windows NT Setup program does not delete the device driver from your hard-disk drive; it only updates Windows NT software configuration information so that the device driver is no longer loaded during system start-up. Swapping a Host Adapter CAUTION: If you have removed a host adapter but still have other host adapters of the same type installed in your computer, do not use Windows NT Setup to remove the device driver. To eliminate the warning message, you must update the Windows NT software configuration as follows: 1. Select and start the Windows NT Setup program. There is a brief pause while Windows NT Setup scans your hardware configuration. 2. Select the Options pull-down menu, and then select Add/Remove SCSI Adapters. The SCSI Adapter setup program displays a list of all host adapters currently installed. 3. Select the host adapter you want to remove, and click Remove. When the Windows NT Setup program asks you for confirmation, click OK. Because SCSI device drivers are loaded during system start-up and because they may be needed to load Windows NT itself, a screen may appear warning you that Windows NT may not start if you remove the SCSI adapter. 4. When you are sure you are removing the correct host adapter type, click OK. 3-28 The procedure for swapping one type of host adapter for another is similar to the procedure for adding a host adapter, except that you make all software configuration changes while Windows NT is running, before you make the hardware changes. 1. Install the driver for the new host adapter by following the steps in “Installing or Updating the Driver With Windows NT 3.51” found earlier in this section. It is not essential to remove the device driver for the host adapter you are replacing. Windows NT dynamically detects the absence or presence of host adapter hardware, and no problems should arise if you leave the existing device driver installed. You can remove the device driver later, after you have successfully rebooted Windows NT. However, if you leave the driver in, the system alerts you with an error message about the extra device driver every time you boot. See “Removing a Host Adapter” found earlier in this section. 2. Once the new device driver is installed, shut down Windows NT and replace the existing host adapter. 3. Restart your computer and Windows NT. Some drive letter assignments may have changed from the previous configuration. Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Troubleshooting for Windows NT Installation Overview The boot manager for Windows NT contains recovery logic to allow you to return to the last known good configuration. If you have changed your host adapter configuration and Windows NT no longer boots, follow these steps to recover: This section provides the information needed to install and use the Dell SCSI drivers for NetWare 3.12 and 4.x. The Dell SCSI drivers for NetWare support the optional Adaptec AHA-2940UW and all Adaptec 78xx series SCSI controllers. 1. Undo any hardware changes you have made to the computer since it was last operational. 2. Reboot the computer. Watch the display carefully during start-up. If the following message appears, press the <Spacebar> and follow the instructions on the screen to continue booting with the last known good configuration: Before you begin installation of the SCSI drivers for Novell NetWare, you must create a diskette of drivers for the version of NetWare you are using (3.12 or 4.x) and a diskette that contains the Adaptec EZ-SCSI utility. Chapter 2, “Using the Dell Server Assistant CD,” provides instructions for creating these diskettes. Press spacebar NOW to invoke the Last Known Good menu 3. Once your computer is operational again, check all of the hardware and software configuration changes you want to make. Look specifically for conflicts with parts of the existing system configuration that are not being changed. If you cannot determine the source of the error, contact Dell for assistance. See Chapter 8, “Getting Help,” in the Diagnostics and Troubleshooting Guide for instructions on contacting Dell for technical assistance. NOTE: Be sure to use the SCSI Driver diskettes created from the Dell Server Assistant CD rather than the SCSI drivers provided with the operating system. The Dell SCSI drivers for NetWare are fully NetWaretested and approved. The NetWare \scsi subdirectory on the NetWare 3.12 drivers diskette you create contains files to be used with NetWare 3.12. The \scsi subdirectory on the NetWare 4.x drivers diskette you create contains files to be used with NetWare 4.x. The following files appear in the \scsi subdirectories on both NetWare driver diskettes: • readme.txt — An American Standard Code for Information Interchange (ASCII) text file describing Adaptec’s drivers for NetWare Installation for Novell NetWare • aic7870.dsk — Adaptec’s 78xx Family driver for NetWare Read this section to find out about the NetWare operating system installation, including: • aspitran.dsk — Adaptec’s ASPI® transport layer driver for NetWare • • • Installing the EZ-SCSI utility • aspicd.dsk — Adaptec’s device driver for a CD-ROM drive • Using command line options that can be specified when the driver is loaded • Automatic driver loading using startup.ncf and autoexec.ncf • Booting a NetWare server from a SCSI drive, formatting media, and using removable media • Error messages generated during initialization Calculating the slot number Installing and/or updating the Dell SCSI driver for NetWare In addition, the \scsi subdirectory on your NetWare 4.x drivers diskette contains the following files: • aic7870.ddi — A driver definition information file to provide setup information to NetWare during installation; NetWare can then prompt you with parameters to be configured for the device driver during the installation process. • • aspicd.ddi — A device driver definition file. aspitran.ddi — A device driver definition file. Installing and Configuring SCSI Drivers 3-29 To begin driver installation, first load the EZ-SCSI utility as described in the following subsection “Installing EZ-SCSI,” and then calculate the slot number as described in “Calculating the Slot Number” found later in this section. Then if you are performing a first-time NetWare installation, see “Installing NetWare and the Driver” found later in this section. If NetWare is already installed in your system, see “Using NetWare to Update or Install the Driver” found later in this section. NOTE: Your system must have a complete version of MS-DOS (version 6.2x) installed before you can complete the Novell NetWare installation. Installing EZ-SCSI The Adaptec EZ-SCSI utility automatically configures the computer to use an Adaptec SCSI host adapter and the devices connected to it. The Adaptec EZ-SCSI utility also copies applications and device drivers to the computer’s hard-disk drive. The configuration and installation process is explained with a series of screens. In most cases, the computer and SCSI devices are configured to take full advantage of all the performance benefits of SCSI when you accept the default values suggested by these screens. Follow these steps to install the Adaptec EZ-SCSI utility: 1. If you have not already done so, create an Adaptec EZ-SCSI diskette for the version of NetWare you are using. Chapter 2, “Using the Dell Server Assistant CD,” provides instructions for creating this diskette. 2. Insert your Adaptec EZ-SCSI diskette into drive A. 3. Type dosinst and press <Enter>. A message appears while the EZ-SCSI utility loads into memory. 4. When the first EZ-SCSI screen appears, read the text carefully. You can press <F1> on any screen for additional help. (Press <Esc> to exit a Help screen.) 5. Press <Enter> to continue with the installation. 3-30 6. Follow the instructions that appear on the screen. Press <Enter> at every screen to accept the EZ-SCSI default values. If you accept all the default values, the EZ-SCSI utility copies the files from the diskette to the c:\scsi directory. (The EZ-SCSI utility creates this directory if the directory does not already exist.) The EZ-SCSI utility also adds command lines to your computer’s configuration files (autoexec.bat and/or config.sys) that will load the required device drivers into memory when you boot your computer. Press <Esc> to continue after the EZ-SCSI utility enters changes to your system configuration files. If you want to copy the files to a different directory or control the changes to your configuration files, follow the instructions on the screen. Press <F1> on any screen to see more information. NOTE: If the EZ-SCSI utility is unable to locate the mscdex.exe file in the c:\dos directory, it will prompt for a pathname to access this file. (Without this file, the utility cannot access the computer’s CD-ROM drive.) When the message (Adaptec EZ-SCSI has been successfully installed…)appears on the screen, press <Enter> or <Esc> to exit the EZSCSI utility, and remove the Adaptec EZ-SCSI diskette from the drive. Then reboot your computer by pressing <Ctrl><Alt><Del>. Calculating the Slot Number The slot number is used to uniquely identify each Adaptec 78xx Family host adapter installed in your system. To properly load the driver for each Adaptec 78xx host adapter, you will need to calculate the slot number in order to include it as part of the load command line. NOTE: The Novell NetWare operating system will automatically calculate the slot number for you if you are installing only one expansion card. If you are installing multiple expansion cards, use the following procedure to calculate the slot number. Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide In order to calculate the slot number, you must first obtain the bus:device xx:xxh values identified when running the SCSISelect utility for your host adapter. This calculation is done manually, as described in the following steps: Follow these steps only if you are installing or upgrading NetWare 4.x for the first time: 1. Make backup copies of all Novell diskettes, and use those backup copies as your working diskettes. Run the SCSISelect utility for your host adapter. 2. Boot MS-DOS on your computer. See “The SCSISelect Utility” found earlier in this chapter for general instructions. 3. Change to the directory where the installation files are found. For a CD-ROM, the subdirectory is similar to d:\netware4.0\english\. 4. Type install and press <Enter>. 5. Select Install New Netware V4.x if you are installing NetWare 4.x for the first time, or Upgrade Netware V3.1x or V4.x if you are upgrading to NetWare 4.x. 6. Follow the instructions in the NetWare User’s Guide for partitioning, creating a server name, and checking the internetwork packet exchange (IPX) network number. 7. When a screen appears asking you to select a disk driver, press <Insert>. 8. Insert the NetWare 4.x driver diskette that you created earlier into the diskette drive. 1. Make sure your system is properly set up and configured. 2. 3. Performing a NetWare 4.x Installation The first screen of the SCSISelect utility displays the bus:device xx:xxh numbers in the upper righthand corner. Write down these numbers exactly as they appear. The bus variable refers to the PCI bus on the system. The default for bus is 0. Usually only one PCI bus is supplied with a system; however, systems may contain more than one PCI bus. The device variable refers to the physical slot number on the PCI bus. The device number is in hexadecimal; you must convert it to a decimal number. NOTE: The device slot number identified through SCSISelect is not the same as the slot number needed to load the driver through the load command line. Use the following formula to calculate the slot number: If you have not already created this diskette, refer to Chapter 2, “Using the Dell Server Assistant CD,” for instructions. slot number = (bus * 100) + device + 16 For example, if the bus:device number is 0:06h (that is, 0:6), then the slot number is 22 (22 = [0 * 100] + 6 + 16). Installing NetWare and the Driver This subsection describes how to install the aic7870.dsk driver at the same time you install NetWare 3.12 or 4.x. If NetWare 3.12 or 4.x is already installed and you wish to install or update the aic7870.dsk driver, see “Using NetWare to Install or Update the Driver” found later in this section. 9. Press <F3>, and specify the path to the aic7870.dsk driver for NetWare (for example, a:\scsi). 10. Select the aic7870.dsk driver and press <Enter>. NOTE: Specific help text for each driver appears in the middle of the screen as you scroll down the list. The Loaded Drivers window below the list of available drivers displays the names of drivers that are loaded and operational. For a new installation, this list is initially empty. For a selective installation, the list shows the diskette drivers already running. 11. Specify the server directory (usually, c:\nwserver) and press <Enter>. The installation program copies the necessary files to this directory. Installing and Configuring SCSI Drivers 3-31 12. When the screen displays Loading driver aic7870.dsk, Please Wait, switch to the System Console screen. 2. Boot MS-DOS on your computer. 3. Change to the directory where the installation files are found. For a CD-ROM, the subdirectory is similar to d:\netware.312\english\. 4. Type install and press <Enter>. Press <Alt><Esc> to switch screens. 13. The driver prompts you for the slot number. Enter the slot number you calculated for your host adapter, and press <Enter>. (See “Calculating the Slot Number” found earlier in this section.) You are automatically switched back to continue with the installation. Follow the procedures in your NetWare documentation for installing a new server or upgrading to a newer NetWare version. 5. 14. When you have correctly entered the slot number, press <F10> to load the driver. 15. If you are using multiple host adapters in your server, you must load the driver again for each host adapter. The correct syntax statement to load the Adaptec Family 78xx driver follows: NOTE: If your system has multiple host adapters, each host adapter must have its own SCSI bus, and its hardware must be configured properly for use with multiple adapters. See the instructions in the host adapter’s User’s Guide. :load [pathname] aic7870.dsk [options] slot=x Command line options are not case sensitive. Placing commas between command line options is optional. See “Using the load Command Line Options” found later in this section for optional values. Refer to the NetWare User’s Guide for information on installing other NetWare Loadable Modules (NLMs). If an error message appears when you attempt to load the driver, see “Troubleshooting for NetWare” found later in this section. 16. Select Continue the Installation to create disk partitions and system volumes, and to specify volume names following the procedures listed in the NetWare User’s Guide. 17. To load the driver automatically at server startup, make sure the startup.ncf file includes the load command line and correct slot number for your host adapter. See “Using startup.ncf and autoexec.ncf” found later in this section. Performing a NetWare 3.12 Installation Follow these instructions only if you are installing NetWare 3.12 for the first time: 1. Make backup copies of all Novell diskettes, and use those backup copies as your working diskettes. 3-32 At the NetWare prompt, use the load command to install the driver from the NetWare 3.12 driver diskette you created earlier. You will also need the slot number described in “Calculating the Slot Number” found earlier in this section. NOTE: The aspitran.dsk module must reside in the same path as the aic7870.dsk driver because NetWare attempts to load the aspitran.dsk file automatically. 6. Load the driver for the first installed host adapter. If you have additional host adapters, you must load the driver again separately for each host adapter. NetWare determines whether loading the driver causes any conflicts between the host adapter and other installed adapters. If there is a possibility of conflict, the driver is not loaded. NOTE: To load the driver automatically at server start-up, copy the driver to the server’s start-up directory and modify the startup.ncf file. See the following section, “Using NetWare to Install or Update the Driver,” and “Using startup.ncf and autoexec.ncf” found later in this section for more information. Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Using NetWare to Install or Update the Driver 3. This section describes how to update or install the aic7870.dsk driver if NetWare 3.12 or 4.x is already installed. If you are installing NetWare 3.12 or 4.x for the first time, see “Installing NetWare and the Driver” found earlier in this section. The correct syntax to load the Adaptec 78xx driver follows: :load [pathname] aic7870.dsk [options] slot=x The instructions for updating or installing the driver are similar for both NetWare 3.12 and 4.x. Procedures that are specific to a particular NetWare version are noted. 1. Make a backup copy of the old driver (if it exists) before installing the new driver. 2. Copy the aic7870.dsk driver and aspitran.dsk module from the NetWare 3.12 or 4.x driver diskette you created into the server’s start-up directory (usually, c:\nwserver) on your hard-disk drive. Doing so overwrites any existing version of the drivers in the directory. NOTE: For both NetWare 3.12 and 4.x, the aic7870.dsk and aspitran.dsk files are located in the scsi subdirectory on the diskette. If necessary, modify the load command line in the startup.ncf file so that the proper path to the driver and the correct slot number are specified. See “Using startup.ncf and autoexec.ncf” found later in this section. Command line options are not case sensitive. Placing commas between command line options is optional. See the next section, “Using the load Command Line Options,” for optional values. To calculate the slot number for each host adapter, see “Calculating the Slot Number” found earlier in this section. 4. Load the driver for the first installed host adapter. If you have additional host adapters, you must load the driver separately for each host adapter. Using the load Command Line Options You can specify several command line options when the Table 3-2. load Command Line Options Option Values Default Description slot= 10-41, 100-141, and so forth None Defines host adapter device location. If none is given, you are prompted to specify one. verbose= y n Causes driver to display host adapter configuration information at load time. removable= on, off on Enables support for removable media. By default, removable media is supported. You may want to disable removable disk support in order to load an ASPI removable disk module. fixed_disk= on, off on Enables support for hard-disk drives. By default, harddisk drives are supported. You may want to disable fixed disk support in order to load an ASPI fixed disk module. * On the AIC-7880 and optional AHA-2940UW, these values become FFFF. NOTE: For the full name of an abbreviation or acronym used in this table, see the Glossary. Installing and Configuring SCSI Drivers 3-33 Table 3-2. load Command Line Options (continued) Option Values Default Description dev_enable= 00-FF* FF Allows you to enable the driver’s registration of SCSI devices on a per-target basis. This enable bit mask is entered in hexadecimal format. (See the following subsection, “Bit Mask Options.”) lun_enable= 00-FF* 01 Enables scanning for specific LUNs on all targets. (See the following subsection, “Bit Mask Options,” for details on creating bit masks.) For example, a value of 7 causes the driver to scan for LUNs 0, 1, and 2 on all targets. The default value of 01 causes the driver to scan LUN 0 only. tag_disable 0-FF* 00 Disables tagged queuing for specific targets. This disable bit mask is entered in hexadecimal format. (See the following subsection, “Bit Mask Options.”) io_combine 0-255 16 Specifies the maximum number of segments in a scatter/ gather list. max_sectors 0-255 64 Specifies the maximum number of sectors in a single scatter/gather segment. max_tags 0-255 8 Specifies the maximum number of tagged commands. max_nontags 0-255 2 Specifies the maximum number of nontagged commands. read_after_write 0, 1, 2 2 Specifies the default verify mode: 0 = No verify on writes, 1 = Software verify, 2 = Hardware verify. instrumentation 0, 1 0 If 1 is entered, the instrumentation option is enabled. The driver maintains internal instrumentation data for use by I/O management applications. Instrumentation can also be enabled by the I/O management application, so inclusion of this option is not necessary. * On the AIC-7880 and optional AHA-2940UW, these values become FFFF. NOTE: For the full name of an abbreviation or acronym used in this table, see the Glossary. 3-34 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Bit Mask Options Use this example to aid in calculating bit-mask option hexadecimal values. Each SCSI device is enabled by a “1” in its corresponding bit position.

NOTE: To load the driver from your hard-disk drive, the aic7870.dsk driver and aspitran.dsk module must be copied from your NetWare 3.12 or 4.x driver diskette to a directory on your hard-disk drive (usually, the server's start-up directory [for example, c:\nwserver]). The syntax to load the aic7870.dsk driver is: 0 0 0 5 Figure 3-1. Bit Position Sample load Command The following command is a sample load command with no option switches (loaded from drive A): load a:\scsi\aic7870 load [pathname] aic7870 [options] slot=x For example, the command line to load the driver from the c:\nwserver directory, with the verbose= option on, and a slot number of 16 follows: load c:\nwserver\aic7870 verbose=y slot=16 NOTE: For each Adaptec 78xx host adapter installed, a separate load command line must be included in the startup.ncf file. The slot number (slot=) identifies the specific adapter. Slot values that already have another registered device do not appear on the screen. Only the slots available for use by the host adapter appear when this command is entered. If an error message appears as you attempt to load the driver, refer to “Troubleshooting for NetWare” found later in this section. To modify the startup.ncf file, follow these steps: The following command is a sample command loading the aic7870.dsk driver with command line options (loaded from drive A): 1. Type install at the NetWare prompt, and press <Enter>. 2. Select the appropriate menu choice that allows you to edit the startup.ncf file. 3. Make the necessary changes. When you are finished, press <F10>. load a:\scsi\aic7870 verbose=y slot=22 Using SCSI Devices Using startup.ncf and autoexec.ncf The following sections provide procedures and tips on the following topics: The startup.ncf and autoexec.ncf files contain a set of commands that are executed at server start-up. The startup.ncf file contains commands to load the disk drivers. Once startup.ncf loads disk drivers, control is passed to the autoexec.ncf file to complete the boot process. For additional information on the startup.ncf and autoexec.ncf files, refer to your NetWare documentation. • • • • • • • Booting from a SCSI device Formatting media Using removable media Using NetWare-tested and -approved drives Using the NetWare tape backup utility Using a CD-ROM drive with NetWare Optimizing performance Installing and Configuring SCSI Drivers 3-35 Booting From a SCSI Device Formatting Media Follow these steps to set your system to boot from a SCSI device: NetWare’s install.nlm program lets you optionally format a hard-disk drive for use with NetWare. If you are using SCSI drives, it allows you to low-level format several SCSI drives simultaneously. The NetWare format procedure is not the same as using fdisk or format under MS-DOS. 1. For an Adaptec 78xx host adapter, use the SCSISelect utility to configure your preferred boot device by setting the Boot Target ID option. 2. Use the MS-DOS fdisk utility to create a small MS-DOS partition. (Follow Novell’s recommendation for size.) MS-DOS must be loaded on sector 0 (zero) of the boot drive. 3. Format the drive using the MS-DOS format command (for example, format c: /s). Boot the system from this drive. 4. Copy the files shown in Table 3-3 to the root directory. Table 3-3. Files Necessary to Set Up Booting From a SCSI Device Diskette Directory Files NetWare System-1 diskette Root server.exe install.nlm NetWare 4.x driver diskette (created from CD) \scsi readme.txt aic7870.dsk aspitran.dsk aic7870.ddi NetWare 3.12 driver diskette (created from CD) \scsi readme.txt aic7870.dsk aspitran.dsk 5. Reboot your server and execute the server.exe file. NetWare should start-up at this point. 6. Enter your file server name and internal IPX number. 3-36 CAUTION: You should not use NetWare to format a hard-disk drive that contains partitions for other operating systems, because that information may be destroyed. NOTE: When you select a hard-disk drive to format, the Install program prompts you to enter an interleave value from 1 to 9. You may also enter an interleave value of 0 (zero). When formatting SCSI hard-disk drives or removable drives on the Adaptec 78xx host adapter SCSI bus, Dell recommends that you use an interleave value of 0. This 0 interleave value instructs the hard-disk drive to use its optimal interleave value. This option was unavailable in NetWare 3.0. Using Removable Media The aic7870.dsk driver module fully supports removable-media disk drives, including magneto-optical drives. Removable media is treated as a standard SCSI hard-disk drive, with some exceptions: • The driver only recognizes and registers media with 512 bytes/sector. • NetWare allows you to mount or dismount the media and lock or unlock the media. Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide These removable media options are supported by NetWare’s monitor.nlm program. Lock Status 1. Load monitor.nlm to display the various options. If your removable-media device supports the lock/unlock feature, you can lock the media (menu option 6). The media must be in the Not Locked state before you can eject it. 2. Select Disk Information. All system hard-disk drives appear. Verify Status 3. Select the removable-media device. Drive status items appear as shown in Table 3-4. Follow these steps to set up the removable media: Menu Options Default Value The Read After Write Verify option (menu option 2) is set to Hardware Level by default. This option cannot be specified in the startup.ncf or autoexec.ncf files. However, the default can be set on the command line. See “Using the load Command Line Options” found earlier in this section. Volume Segments on Drive1 (select for list) The available options are defined as shown in Table 3-5. Table 3-4. Drive Status Items Table 3-5. Read After Write Verify Options Hardware Level Option Setting Function Drive Light Status1 Not supported Disabled Driver Operating Status1 Active All writes to SCSI disk drives are executed with the SCSI Write command (0Ah or 2Ah). Removable Drive Mount Status2 Mounted Hardware Level Removable Drive Lock Status2 Not Locked All writes to SCSI disk drives are executed with the SCSI Write and Verify command (2Eh) or (if this command is not supported by the drive) with the SCSI Write command (0Ah or 2Ah), followed by the SCSI Verify command (2Fh). Software Level Not supported. Read After Write Verify1 1 Valid for both removable and nonremovable types of SCSI drives. 2 Valid for removable media only. Mount Status Mounting causes a drive to come online as a NetWare storage device. Dismounted drives are inactive and cannot be accessed. Before you eject your current media, you should first dismount it (menu option 5). When the media status is dismounted, you can eject the media. However, NetWare does not allow you to dismount media if it is locked. To insert your new media, wait for the drive to spin up, and then select the Removable Drive Mount Status option. Using NetWare-Tested and -Approved Drives In order for a drive and host adapter to be fully certified as NetWare “Yes, Tested and Approved,” they must both pass a qualification process that takes place before you see the product. The goals of NetWare testing are to simplify installation and provide the highest quality disk subsystem. Installing and Configuring SCSI Drivers 3-37 Adaptec 78xx Family host adapters and their drivers are fully NetWare-tested and -approved. This means that you can purchase a NetWare drive (certified as “Yes, Tested and Approved”) from a vendor, connect it to your computer system or host adapter, partition it, and create a volume without any compatibility concerns. Adaptec’s aic7870.dsk driver module is flexible enough to allow you to connect NetWare-tested and -approved SCSI drives as well as standard SCSI drives to a single host adapter. The driver registers each hard-disk drive accordingly. Drive registration is a user-transparent process; no user interaction is required. You can tell that the drive has been detected as NetWare-tested and -approved if the message NetWare Yes Tested and Approved is included in the drive description string that appears when you run monitor.nlm (disk options). Using the NetWare Tape Backup Utility Included with NetWare is a server-based tape backup utility called sbackup.nlm. This allows backup of server disk drives to a server tape drive. The sbackup.nlm utility supports Adaptec host adapters. 1. Load the SCSI adapter driver. The syntax to load the aic7870.dsk driver is: load [pathname] aic7870 [options] slot=x The ASPI layer (aspitran.dsk) is automatically loaded. 2. Refer to the Novell NetWare documentation for additional instructions on loading the server backup software. Refer to the NetWare Server Backup User’s Guide to load the tsa and sbackup modules. Setting Up a CD-ROM Drive With NetWare 3.12 or 4.x To use a CD-ROM drive with NetWare 3.12 or 4.x, follow these instructions: 1. 2. Load aspicd.dsk by entering the following command line: :load [pathname] aspicd.dsk NOTE: If aspicd.dsk does not work, unload it and load it again. The first load initializes the host adapter; unloading and reloading allows the initialization to complete. 3. Load cdrom.nlm as follows: :load [pathname] cdrom.nlm 4. Enter the following line at the prompt, and then note the number and name of the CD that appears: :cd device list 5. Enter the number and volume name of the CD at the command line: :cd mount [number] [name] The CD-ROM is now ready to be accessed as a volume. Optimizing Performance The Adaptec 78xx SCSI bus master firmware increases the SCSI performance of the Adaptec 78xx Family host adapters under multitasking environments. The firmware uses a paging mechanism to handle up to 255 simultaneous SCSI commands. The sequencer can simultaneously manage up to 32 tagged, or 2 nontagged, SCSI commands for each SCSI device, up to a limit of 255 SCSI commands. The firmware can queue as many commands as the operating system is able to send to the host adapter. To set this feature, enter the following command: max_tags=n In general, a low number for the max_tags option gives better sequential performance. This value varies with the level of random disk accesses and drive characteristics. NOTE: A large value for max_tags can cause starvation problems with some drives. Load aic7870.dsk by entering the following command line: :load [pathname] aic7870.dsk slot=x 3-38 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Troubleshooting for NetWare Any error that occurs while the driver is initializing prevents it from loading. If an error does occur, the driver causes the computer to beep and then display a numbered error message: 003 Invalid command line option entered > option An invalid option was entered on the command line. The invalid option that was entered is also displayed. xxx message 004 Invalid command line, please enter correctly The xxx indicates the error code, and message is a descriptive line describing the error. The error codes are divided into three categories: The driver was unable to understand the command line options you entered. Be sure you have entered these options correctly. 000-099 Non–host-adapter specific 100-299 Host-adapter specific 300-999 Reserved Specific error codes appear only if you have installed the host adapters and drivers that generate them. Non–Host-Adapter Specific 000 Failed ParseDriverParameters call A call to NetWare’s ParseDriverParameters routine has failed for some unknown reason. The command line contains errors, or you pressed <Esc> at the port or slot prompt. 001 Unable to reserve hardware, possible conflict The driver failed in its attempt to reserve the host adapter’s hardware settings (that is, direct memory access [DMA] and interrupt request [IRQ] settings). Another card in your system may be causing a conflict with the host adapter. 002 NetWare rejected card Failed AddDiskSystem call The driver failed in its attempt to register the host adapter with NetWare. The file server may not have enough memory. Host-Adapter Specific 200 No host adapter found for this driver to register No Adaptec 78xx host adapter was found in your computer for the driver to register. Be sure the host adapter is properly configured and properly seated in the slot. 203 Invalid ‘device’ setting You have entered an invalid slot setting on the command line. You can only enter slot numbers for valid host adapters. If you load without the slot option, you will be prompted to enter a valid value. 204 Invalid ‘verbose’ setting, use ‘y’ You can only enter y for this option (verbose = y). 205 Invalid ‘removable’ setting, use ‘off’ You can only enter off for this option (removable = off). 206 Invalid ‘fixed_disk’ setting, use ‘off’ You can only enter off for this option (fixed_disk = off). 208 SCSI present but not enabled/configured for PCI A host adapter is present, but its bus or device entry has not been enabled. Installing and Configuring SCSI Drivers 3-39 3-40 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Chapter 4 Using the System Setup Program E ach time you turn on your computer system or press the reset button, the system compares the hardware installed in the system to the hardware listed in the system configuration information stored in nonvolatile random-access memory (NVRAM) on the system board. If the system detects a discrepancy between the two, it generates error messages that identify the incorrect configuration settings. The system then prompts you to enter the System Setup program to correct the setting. You can use the System Setup program as follows: • To change the system configuration information after you add, change, or remove any hardware in your system • To set or change user-selectable options—for example, the time or date on your system CAUTION: Whenever you make changes to the System Setup program or add, reposition, or remove Extended Industry-Standard Architecture (EISA) or Industry-Standard Architecture (ISA) expansion cards, add or remove memory, or change settings for built-in devices, you must run the EISA Configuration Utility, make any necessary changes, and save the system configuration information. Failure to do so may cause resource conflicts between Peripheral Component Interconnect (PCI) devices (such as PCI expansion cards, the built-in video controller, or the built-in small computer system interface [SCSI] host adapter). See “Configuring EISA, ISA, and PCI Expansion Cards” in Chapter 5 for more information about how PCI devices are configured based on settings in the EISA Configuration Utility. When you save changes and exit the System Setup program, the system automatically reboots causing any changes to take effect immediately. After you set up your system, run the System Setup program to familiarize yourself with your system configuration information and optional settings. Dell recommends that you print out the System Setup screens or write down the information for future reference. Before you use the System Setup program, you need to know the kind of diskette drive(s) installed in your computer. (The standard diskette drive is a 1.44-megabyte (MB) 3.5-inch drive). System Setup Screens The System Setup screens display the current setup and configuration information and optional settings for your system. Information on the System Setup screens is organized in five boxed areas: • Title Box The box at the top of each screen lists the system name, and the revision number of the basic input/ output system (BIOS) as detected by the system. • Configuration Options and System Data The box on the left side of each screen lists categories that define the installed hardware in your system. Fields beside the categories contain options or values. System data that is not user-selectable is displayed in the lower part of the Main menu screen. Using the System Setup Program 4-41 • Table 4-1. System Setup Keys (continued) Help The box on the upper-right side of each screen displays help information for the category whose field is currently highlighted. • Keys Key Functions The area at the bottom of each screen lists the keys and their specific functions, which are also listed in Table 4-1.

Entering the System Setup Program NOTE: To ensure an orderly system shutdown, consult the documentation that accompanied your operating system. You can enter the System Setup program by pressing the <F2> key when prompted while the computer is starting up. You can also enter the System Setup program by responding to certain error messages. (See “Responding to Error Messages” at the end of this chapter.) If you wait too long, your operating system begins to load into memory. In this case, let the system complete the load operation; then restart the system and try again. The following sections describe the System Setup categories in the Main, Advanced, Security, and Exit menus. configuration options and system data title box help key functions Figure 4-1. Main Menu of the System Setup Program Using the System Setup Program 4-43 Main Menu Categories To access the Main menu (see Figure 4-1), use the arrow keys to highlight Main. This section explains in detail each of the System Setup categories in the Main menu and the Boot Sequence submenu. Time Time resets the time on the computer’s internal clock. Time is kept in a 24-hour format (hours:minutes: seconds). To change the time, use the plus and minus keys. If you prefer, you can type numbers in each of the appropriate fields. NOTE: If your system is connected to a network, the Time category may reflect the time maintained by the network server, depending upon how the network is configured. In this case, changing the Time category on your system has no effect. Date Date resets the date on the computer’s internal calendar. Your system automatically displays the day of the week corresponding to the settings in the three fields that follow (month, day-of-the-month, and year). To change the date, use the plus and minus keys to increase and decrease the numbers. If you prefer, you can type numbers in the day-of-the-month fields. NOTE: If your system is connected to a network, the Date category may reflect the date maintained by the network server, depending upon how the network is configured. In this case, changing the Date category on your system has no effect. Diskette Drive A and Diskette Drive B Diskette Drive A and Diskette Drive B identify the type of diskette drives installed in the drive cage. The options for both categories are: • • • • • 360 KB, 5.25 Inch 1.2 MB, 5.25 Inch 720 KB, 3.5 Inch 1.44 MB, 3.5 Inch (default for diskette A) Not Installed (default for diskette B) 4-44 Fast Video BIOS Fast Video BIOS offers the options of shadowing and/or caching the video BIOS for improved performance. For the built-in video controller chip, the Fast Video BIOS category offers the following options: • • • On and Cached (The Default) On Off If you choose the On option, your system boots and immediately copies the video BIOS code from the flash memory chip into write-protected memory locations in faster random-access memory (RAM). This process is known as shadowing. If you choose On and Cached (the default), your system boots and not only shadows the video BIOS code, but also allows it to be cached. Caching saves time for the microprocessor(s) by holding available the most recently accessed data and instructions in an intermediate storage area of static RAM (SRAM), which is faster than system RAM. Shadowing and caching let the system manipulate video display data more quickly and easily, improving video performance. Memory Cache Memory Cache can be set to Enabled (the default) or Disabled. Cache memory decreases the average memory cycle time to boost system performance. You may want to set Cache to Off to aid in troubleshooting software problems. Boot Sequence The Boot Sequence category can be set to A: then C: (the default), C: then A:, or C: Only. The term boot refers to the system’s start-up procedure. When turned on, the system “bootstraps” itself into an operational state by loading into memory a small program which in turn loads the necessary operating system. Boot Sequence tells the system where to look for the files that it needs to load. Selecting A: then C: causes the system to try booting from drive A first. If it finds a diskette that is not bootable in the drive or finds a problem with the drive itself, the system displays an error message. If it does not find a diskette in the drive, the system then tries to boot from the hard-disk drive (drive C). Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Selecting C: Only causes the system to boot only from the hard-disk drive, even if there is a bootable diskette in drive A. You might select the C: Only option to prevent an unauthorized person from accessing the system by booting from a diskette. configuration options and system data Boot Options Submenu Categories To access the Boot Options submenu (see Figure 4-2), highlight the Boot Sequence category in the Main menu and press <Enter>. title box help key functions Figure 4-2.

Security Menu of the System Setup Program Using the System Setup Program 4-49 Supervisor Password Is Set User Password This category displays whether the supervisor password is disabled or enabled. When Enabled is displayed, the supervisor password has already been set and is required in order to have full access (see Table 4-2) to the System Setup program. The default is Disabled. NOTE: You cannot set the user password until a supervisor password is set. User Password Is NOTE: Read “Using the User Password Feature” later in this chapter for detailed instructions on assigning a user password and using, deleting, or changing an existing user password. See “Disabling a Forgotten Password” found later in this chapter for information on disabling a forgotten user password. This category displays whether the user password is disabled or enabled. When Enabled is displayed, the user password has already been set and is required at start up. Unlike the supervisor password, the user password does not allow you full access (see Table 4-2) to the System Setup program. The default is Disabled. Set Supervisor Password The Set Supervisor Password category lets you restrict access to your computer’s System Setup program in the same way that you restrict access to your system with the user password feature. NOTE: Read “Using the Supervisor Password Feature” later in this chapter for detailed instructions on assigning a supervisor password and using, deleting, or changing an existing supervisor password. See “Disabling a Forgotten Password” found later in this chapter for information on disabling a forgotten supervisor password. The Set User Password category lets you restrict access to your system by setting a user password that is required when the Password On Boot category is set to Enabled. Password on Boot The Password On Boot category allows you to require a supervisor password during the boot-up process when the category is set to Enabled. The default is Disabled. Diskette Access The Supervisor setting restricts access of diskette drives to the supervisor only. The User setting (the default) allows access to the supervisor and the user. System Backup Reminder This category lets you display a message during start-up at selected intervals to remind you to back up the system. The options are as follows: • • • • 4-50 Disabled (default) Daily Weekly Monthly Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Virus Check Reminder This category lets you display a message during start-up at selected intervals to remind you to check your system for viruses.

The following section explains in detail each of the System Setup categories in the Exit Daily Weekly configuration options and system data title box help key functions Figure 4-5. Exit Menu of the System Setup Program Using the System Setup Program 4-51 Save Changes & Exit When you choose this option, the BIOS stores the changes you have made in a complementary metal-oxide semiconductor (CMOS), exits the System Setup program, and reboots the system. When your system reboots, the BIOS configures the system according to the selections stored in CMOS. Exit Without Saving Changes Exits the System Setup program without saving any of the changes you have made. Get Default Values Loads the default values for each menu in the System Setup program. Load Previous Values Loads the values previously stored in CMOS for each menu. Save Changes Stores your changes in CMOS but does not exit the System Setup program. Using the Password Features CAUTION: The password features provide a basic level of security for the data on your system. However, they are not foolproof. If your data requires more security, it is your responsibility to obtain and use additional forms of protection, such as data encryption programs. Using the Supervisor Password Feature Your Dell system is shipped to you with the supervisor password set to Disabled, which allows you to enter the System Setup program and assign a password. When the Supervisor Password Is category is set to Enabled, the computer system prompts you for the supervisor password whenever you enter the System Setup program. If system 4-52 security is a concern, you should operate your system with supervisor password protection. You can assign a supervisor password, as described in the next subsection, “Assigning a Supervisor Password,” whenever you use the System Setup program. Once a supervisor password is assigned, only those who know the password have full use of the System Setup program. To delete or change an existing supervisor password, you must know the supervisor password (see “Deleting or Changing an Existing Supervisor Password” found later in this section). NOTE: You can also assign, delete, or change a supervisor password through the EISA Configuration Utility. See “Assigning a Supervisor Password” and “Deleting or Changing an Existing Supervisor Password” in Chapter 5. If you assign and then forget a supervisor password, you need your computer key to get inside the computer, where you can change a jumper setting to disable the supervisor password feature (see “Disabling a Forgotten Password” found later in this section). Note that you erase the user password at the same time. NOTE: The system allows you three attempts to enter a password. After three failed attempts, the keyboard locks up and you must reboot the system before you can try entering a password again. Assigning a Supervisor Password A supervisor password can be assigned only when the Supervisor Password Is category is set to Disabled. Press <Enter> to display a dialog box in which you can enter the password. You can use up to seven alphanumeric characters in a password, and the password is not case sensitive (meaning that there is no difference between uppercase and lowercase characters). NOTE: The supervisor password can be the same as the user password. However, a user password cannot be set until a supervisor password has been set. After you verify the password, the Supervisor Password Is setting changes to Enabled. The next time you attempt to enter the System Setup program, the system prompts you for the supervisor password. Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Keep the following tips in mind when setting your password: • You can use up to seven alphanumeric characters in your password (passwords are not case sensitive). • As you press each character key (or the <Spacebar> for a blank space), a placeholder appears in the field. • To erase a character when entering your password, press the <Backspace> key or the left-arrow key. NOTES: The password assignment operation recognizes keys by their location on the keyboard, without distinguishing between lowercase and uppercase characters. For example, if you have an M in your password, the system recognizes either M or m as correct. Certain key combinations are not valid. If you enter one of these combinations, a beep sounds. To exit the field without assigning a supervisor password, press the up-arrow or down-arrow key to move the highlight to another field, or press the <Esc> key at any time before setting a new password. Using Your Supervisor Password to Secure Your System Each time you turn on your system, reboot the system, or press the reset button, the following prompt appears on the screen (if the Password On Boot category is set to Enabled). Enter password: After you enter the correct supervisor password and press <Enter>, your system boots and you can use the keyboard to operate your system as usual. If a wrong or incomplete password is entered, the following message appears on the screen: Warning, Invalid password. Press <Enter> to continue Enter the password again. If an incorrect or incomplete supervisor password is entered again, the same message appears on the screen. The third time an incorrect or incomplete password is entered, the keyboard locks up and displays the following message: SYSTEM DISABLED You must reboot the system before you can attempt to enter a password again. Operating With a Supervisor Password Enabled If Supervisor Password Is is set to Enabled, you must enter the correct supervisor password before you can modify any System Setup categories (other than the Time, Date, Num Lock, and Speaker categories). Deleting or Changing an Existing Supervisor Password To disable the supervisor password, press <Enter> to display the Set Password dialog box, and then press <Enter> two more times. When the Supervisor Password Is category displays Disabled, you can assign a supervisor password or operate the system with no password assigned. To change an existing supervisor password, first enter the System Setup program and disable the current password. Then, with the Supervisor Password Is category set to Disabled, assign a new supervisor password as described in “Assigning a Supervisor Password” earlier in this section. Using the User Password Feature Your Dell system is shipped to you with the user password feature set to Disabled. After you assign a user password, set the User Password Is category to Enabled, and set the Password On Boot category to Enabled, the computer system prompts you for the user password at system start-up. If system security is a concern, you should operate your system with user password protection. You can assign a user password, as described in the next subsection, “Assigning a User Password,” whenever you use the System Setup program. Once you assign a user password, only those who know the password have full use of the system. NOTE: You can also assign, delete, or change a user password through the EISA Configuration Utility. See “Assigning or Changing a User Password” and “Deleting an Existing User Password” in Chapter 5. To disable the user password, press <Enter> to display the Set Password dialog box, and then press <Enter> two more times. If you assign and then forget a user password, you must remove the cover of the computer (which may require Using the System Setup Program 4-53 unlocking the computer’s keylock) and change a jumper setting to temporarily disable the user password feature (see “Disabling a Forgotten Password” found later in this section). Note that you erase the supervisor password at the same time. CAUTION: If you leave your system running and unattended, anyone can access the data stored in your system even with a user password assigned. To protect your system while it is running, you must use additional forms of protection, such as screensaver software protected by a password. CAUTION: With the password features disabled, your system operates as if it did not contain password features. If you leave your system running and unattended without having a system and/or supervisor password assigned or with the password features disabled, anyone can assign a system and/or supervisor password that will be unknown to you. NOTE: The system allows you three attempts to enter a password. After three failed attempts, the keyboard locks up and you must reboot the system before you can try entering a password again. Keep the following tips in mind when setting your password: • You can use up to seven alphanumeric characters in your password (passwords are not case sensitive). • As you press each character key (or the <Spacebar> for a blank space), a placeholder appears in the field. • To erase a character when entering your password, press the <Backspace> key or the left-arrow key. NOTES: The password assignment operation recognizes keys by their location on the keyboard, without distinguishing between lowercase and uppercase characters. For example, if you have an M in your password, the system recognizes either M or m as correct. Certain key combinations are not valid. If you enter one of these combinations, a beep sounds. To exit the field without assigning a user password, press the up-arrow or down-arrow key to move the highlight to another field, or press the <Esc> key at any time before setting a new password. Using Your User Password to Secure Your System Each time you turn on your system, reboot the system, or press the reset button, the following prompt appears on the screen: Assigning a User Password Enter password: NOTE: You cannot assign a user password until a supervisor password has been set. After you enter the correct user password and press <Enter>, your system boots and you can use the keyboard to operate your system as usual. When in the Set User Password category, you can press <Enter> to display a dialog box in which you can enter a user password. You can use up to seven alphanumeric characters in a password, and the password is not case sensitive (meaning that there is no difference between uppercase and lowercase characters). When a user password is set, the status shown in the User Password Is category is Enabled. With no user password assigned and with a jumper plug installed on the password jumper (PASSWD) on the system board (its default setting), the status shown in the User Password category is set to Disabled. If a wrong or incomplete password is entered, the following message appears on the screen: Warning, Invalid password. Press <Enter> to continue Enter the password again. If an incorrect or incomplete user password is entered again, the same message appears on the screen. The third time an incorrect or incomplete password is entered, the keyboard locks up and displays the following message: SYSTEM DISABLED 4-54 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide You must reboot the system before you can attempt to enter a password again. Deleting or Changing an Existing User Password To disable the user password, press <Enter> to display the Set Password dialog box, and then press <Enter> two more times. 2. Refer to “Jumpers” and Table B-1 in Appendix B for jumper information, and to Figure B-1 for the location of the password jumper (labeled “PASSWD”) on the system board. 3. Remove the jumper plug from the PASSWD jumper (the disabled setting). 4. Replace the computer cover according to the instructions in “Replacing the Computer Cover” in Chapter 6, reconnect your computer to its power source, and turn it on. When the User Password Is category displays Disabled, you can assign a user password or operate the system with no password assigned. To change an existing user password, first enter the System Setup program and disable the current password. Then, with the User Password Is category set to Disabled, assign a new user password as described in “Assigning a User Password” earlier in this section. Disabling a Forgotten Password If you forget your user or supervisor password, you cannot operate your system or change settings in the System Setup program, respectively, until you open the computer chassis, change the password jumper setting to disable the passwords, and erase the existing passwords. To disable a forgotten password, perform the following steps: 1. Booting your system with the PASSWD jumper removed erases the existing password(s). NOTE: Before you assign a new system and/or supervisor password, you must reinstall the jumper plug on the PASSWD jumper. 5. Repeat step 1. 6. Reinstall the jumper plug on the PASSWD jumper pins (the enabled setting). 7. Repeat step 4. 8. Assign a new system and/or supervisor password. To assign a new user password, see “Assigning a User Password” found earlier in this section. To assign a new supervisor password, see “Assigning a Supervisor Password” found earlier in this section. Remove the computer cover according to the instructions in “Removing the Computer Cover” in Chapter 6. CAUTION: See “Protecting Against Electrostatic Discharge” in the safety instructions at the front of this guide. Using the System Setup Program 4-55 Password Options Table 4-2 lists several ways the supervisor and user password and the Password On Boot category can be used to provide security for your system.

Disabled N/A N/A No No You are not prompted for a password at boot or for access to System Setup. You can change any category in System Setup. Comments 1 The system always requests a password at boot if the user password is enabled. 2 If you press <Esc> at the setup password prompt, you can access the System Setup program, but can change only the categories described in note 3 below. 3 The user can change only the Date, Time, Num Lock, Speaker, and Set User Password categories unless the supervisor password is entered. 4-56 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Responding to Error Messages If an error message appears on your monitor screen while the system is booting, make a note of the message. Then, before entering the System Setup program, refer to the chapter titled “Messages and Codes” in your Diagnostics and Troubleshooting Guide for an explanation of the message and suggestions for correcting any errors. (An exception to this routine: It is normal to receive an error message the first time you boot your system after installing a memory upgrade. In that situation, you do not need to refer to the Diagnostics and Troubleshooting Guide— just follow the instructions in “Performing a Memory Upgrade” in Chapter 7 of this guide.) If you are given the option of pressing either <F1> to continue or <F2> to run the System Setup program, press the <F2> key. Using the System Setup Program 4-57 4-58 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Chapter 5 Using the EISA Configuration Utility T he EISA Configuration Utility is used to tell the system what expansion cards are installed and which expansion slots they occupy. With this information, the system automatically configures Extended IndustryStandard Architecture (EISA) cards and can tell you how to configure Industry-Standard Architecture (ISA) cards manually by setting jumpers or switches. Before your system was shipped from Dell, a technician used the EISA Configuration Utility to enter the correct information for the expansion cards initially installed in your computer. The EISA Configuration Utility also monitors the resources required by any installed Peripheral Component Interconnect (PCI) expansion card. After installing or moving a PCI expansion card, you should run the EISA Configuration Utility to update the system’s database of available system resources stored in nonvolatile random-access memory (NVRAM). Configuring EISA, ISA, and PCI Expansion Cards Whenever you add, remove, or reposition an EISA or ISA expansion card, use the EISA Configuration Utility to reconfigure your system. The utility reads the card’s corresponding configuration file (.cfg file), which describes the card’s characteristics and required system resources, and then uses this information to create a conflict-free configuration. (You can also use the EISA Configuration Utility to set certain system operating parameters known as system board options, as well as to correct the system configuration information.) The EISA Configuration Utility is PCI aware and can also be used to configure PCI expansion cards. Configuration information for PCI expansion cards is contained within the card, so no additional .cfg file is required. You should run the EISA Configuration Utility after installing or moving a PCI expansion card to keep the system’s database of available resources accurate. If the EISA Configuration Utility is not aware of an installed ISA or EISA expansion card, resource conflicts can arise. For this reason, it is extremely important to enter information about ISA expansion cards, as well as EISA expansion cards, into the EISA Configuration Utility. In addition, certain ISA graphics adapter cards and multiport serial cards require some memory or caching reconfiguration provided by the EISA Configuration Utility. NOTE: The System Setup program allows you to change the interrupt requests (IRQs) for the serial and parallel ports to maximize system performance. See “Advanced Menu Categories” in Chapter 4 for instructions. System Board Options In addition to configuring expansion cards, you can use the EISA Configuration Utility to change certain system board options, as described in “Step 3: View or Edit Details” found later in this chapter. Many of the system board options in the EISA Configuration Utility correspond to categories in the System Setup program. Although the two utilities are separate, the EISA Configuration Utility automatically forwards changes to, and reads changes from, the System Setup program. Thus, for configuration options that appear in both utilities, you can set the options through either utility. NOTE: In most cases, your system operates according to the most recent changes, regardless of which utility you use to make the changes. However, some software written Using the EISA Configuration Utility 5-59 for EISA systems may require that the change be saved to the EISA configuration memory to operate properly. How to Run the EISA Configuration Utility The EISA Configuration Utility is included on the Dell Server Assistant CD shipped with your system. This CD includes an EISA Configuration Utility directory that contains the main program plus a directory of .cfg files for many—but not all—ISA expansion cards. You can run the EISA Configuration Utility directly from the CD or from a diskette that you create using the CD’s main menu. Dell recommends that you run the EISA Configuration Utility from a diskette because it is not compatible with all operating systems. Also, using a diskette to run the utility allows you to copy any system configuration changes to the diskette for safekeeping. See Chapter 2, “Using the Dell Server Assistant CD,” for instructions on creating an EISA Configuration Utility diskette. When you buy an EISA expansion card, you receive a configuration diskette containing the card’s configuration file with the filename extension .cfg. Copy this .cfg file to your EISA Configuration Utility diskette. The EISA Configuration Utility uses the information in this file to configure the new card. When you buy an ISA expansion card, copy the appropriate configuration file (contained in the .cfg directory on the diskette) to your EISA Configuration Utility diskette. If the .cfg directory does not contain a configuration file for your ISA expansion card, use the generic ISA card configuration file, which is included in the .cfg directory on the CD. Instructions for using the generic .cfg file are included in “Adding an Expansion Card” found later in this chapter. PCI expansion cards do not require a configuration file. The PCI configuration utility in ROM automatically uses the information maintained by the EISA to assign resources for PCI expansion cards. CAUTION: You must use the EISA Configuration Utility when you add an EISA or ISA expansion card to your computer. For an ISA card, use the specific configuration file for your expansion card, if one is available, rather than the generic ISA card configuration file. The generic ISA card configuration file cannot be used to identify potential resource conflicts or proper jumper and switch settings. When to Run the EISA Configuration Utility Whenever you add, remove, or reposition an ISA or EISA expansion card, you must run the EISA Configuration Utility to specify which expansion slot the card is installed in and to ensure that no two cards attempt to use the same resources (such as IRQ lines). When you use the utility with ISA expansion cards, run the program before adding, removing, or repositioning any cards. The EISA Configuration Utility can identify and resolve any resource conflicts, as well as indicate the proper jumper and switch settings for each expansion card to avoid such conflicts. Running the program first helps you determine how to configure the expansion card before it is installed in your computer. When you use the utility with EISA expansion cards, you should normally run the program after adding, removing, or repositioning the card. However, some cards have ROM or a device driver that examines the configuration information stored in NVRAM; these cards require that you run the program before the card is installed. Each configuration file for an EISA expansion card has an identification number the utility reads before configuring the card. EISA expansion cards have no jumpers or switches that must be set before the card is installed. When you use the utility with PCI expansion cards, you should run the program after adding a PCI expansion card so the EISA Configuration Utility will have a current record of assigned resources. NOTE: If your system detects a card configuration problem during operation, you receive a warning message directing you to run the EISA Configuration Utility to correct the problem. 5-60 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Making Selections in the EISA Configuration Utility that accompanied these programs for instructions on removing them from memory. The EISA Configuration Utility uses menus to guide you through the configuration process. The menus and their options are accessed through keyboard commands. If you start the utility and there is not enough memory to run it, a message is displayed. If you receive such a message, run the utility from a diskette. To make a menu selection, use the up- or down-arrow key to highlight the desired option, and then press <Enter>. In the Help menu or Advanced menu, you can also select an option by pressing the key that corresponds to the highlighted letter in the selection list. Follow these steps the first time you use the EISA Configuration Utility. Later, if a card is added, removed, or repositioned, you must follow the procedure described in “Step 2: Add or Remove Boards” found later in this chapter. To scroll up or down a screen, press the <Page Up> or <Page Down> key, respectively. Using Online Instructions The EISA Configuration Utility has online instructions for each of its procedures. If you need help at any time, press <F1> to see a help screen that offers more details about the task you are doing. Starting the EISA Configuration Utility NOTE: Your system’s default hardware configuration allows updating of the EISA configuration information. However, if the EISA jumper on the system board is installed, the EISA configuration information cannot be updated until the jumper plug is removed. If you have reason to think the EISA jumper setting has been changed, check the jumper before attempting to make an EISA configuration change. For instructions on removing and replacing the computer cover, see “Removing the Computer Cover” and “Replacing the Computer Cover” in Chapter 6. For information on the EISA jumper location and settings, see Figure B-1 and Table B-1, respectively in Appendix B, “Hardware Configuration Features.” If you are running the EISA Configuration Utility from your hard-disk drive, remove any TSR programs from memory before starting the utility. These programs take up space in system memory even when they are not running, thus reducing the amount of memory available to the EISA Configuration Utility. See the documentation 1. To run the program from a diskette, insert into drive A the EISA Configuration Utility diskette that you created from the CD. Then either turn on your computer or reboot it by pressing the <Ctrl><Alt><Del> key combination or the reset button. To run the program from your hard-disk drive, switch to the c:\eisacfg subdirectory, type at the operating system prompt, and press <Enter>. To run the program from the Dell Server Assistant CD, restart the system from the CD. Select Run EISA Configuration Utility from the CD’s main menu. To access the advanced options (described in “Advanced Menu” in this chapter), press <Ctrl><a> at the Welcome screen. You can run the EISA Configuration Utility in modeling mode by typing at the operating system prompt and pressing <Enter>. NOTE: To use modeling mode, you must run the EISA Configuration Utility from your hard-disk drive. Modeling mode lets you set up configuration parameters for a system different from the one you are using and allows you to save a configuration to a file. Modeling mode is useful if you need to configure many systems identically; instead of using the EISA Configuration Utility to configure each system, you can transfer the configuration file to a diskette and load it onto each system.

Step 3: View or Edit Details The EISA Configuration Utility lets you set a variety of system options through the .sci file. Through this file, you can notify the system of changes to your hardware and memory configuration, set and change your passwords, manage input/output (I/O) ports, and set other system operating parameters. Some of the categories do not offer options, but reflect installed hardware detected by the system. These items are displayed for your information only; you cannot change them through the utility. Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide NOTES: Most system board options available through the EISA Configuration Utility are also available through the System Setup program as described in Chapter 4, “Using the System Setup Program.” Although the EISA Configuration Utility is separate from the System Setup program, the EISA utility forwards changes to, and reads changes from, corresponding categories in the System Setup program. However, when the EISA Configuration Utility reads a change from the System Setup program, that change is not stored in EISA configuration memory until you start the EISA Configuration Utility, let it read the changes from the System Setup program, and then save the configuration. To avoid possible resource conflicts, start the EISA Configuration Utility and save the configuration after making System Setup program changes that allocate system resources. In addition, some software written for EISA systems may require that the changes be saved to the EISA configuration memory for proper operation. NOTES: Several system board categories allow you to edit such resources as memory address, I/O ports, IRQs, and direct memory access (DMA) channels. It may be necessary to edit these resources to resolve a configuration conflict. To view the resource screen for any category, highlight the option and press <F6>. The edit resources feature is intended for users who are technically knowledgeable. Do not change resource settings from their defaults if you do not understand how such a change will affect system performance. While in the Step 3: View or Edit Details menu, you can press <F7> to enter the Advanced menu. See “Advanced Menu” found later in this chapter for more information. When you have finished making changes, save the new system configuration information and exit the utility as follows: 1. Press <F10>, and select Step 5: Save and Exit from the Steps in Configuring Your Computer menu. 2. Select Save the Configuration and Restart the Computer from the menu that appears. Display the list of system board options as follows: 1. Start the EISA Configuration Utility as described in “Starting the EISA Configuration Utility” found earlier in this chapter. 2. At the Main Menu, select Configure Computer. 3. If the EISA Configuration Utility prompts you for a supervisor password, type the password and press <Enter>. 4. After the configuration files are loaded, select Step 3: View or Edit Details. A list of system board options appears on the screen. Figure 5-1 shows settings typical for your system. NOTES: If the EISA Configuration Utility prompted you for a supervisor password in step 3 but you were unable to correctly specify it, you can only view the EISA System Board Options screen. You cannot change any of the values or settings. Whenever you add an expansion card to the computer, its presence is reflected by changes to the EISA System Board Options screen. To select a category on the list of system board options, press the up- or down-arrow key to highlight the category and press <Enter>. A pop-up menu appears, listing the options for that category. To select an option, press the up- or down-arrow key to highlight the option and press <Enter>. The following system board options are available on the EISA System Board Options screen (see Figure 5-1). Some of the options are the same as options on the System Setup screens.

EISA System Board Options Screen (Example) Using the EISA Configuration Utility 5-67 Step 4: Examine Switches or Print Report Maintain System Configuration Diskette The Step 4: Examine Switches or Print Report option lists the required switch and jumper settings for each expansion card in your computer. To view the settings, highlight the card and press <Enter>. For ISA expansion cards, it is important to compare the jumper and switch settings listed on the screen to the actual settings on the card. Using the Maintain System Configuration Diskette option, you can create a backup copy of the .sci file or use a previously saved .sci file to reconfigure your system or to identically configure many other systems. You can also copy .cfg files and delete .sci and .cfg files from your EISA Configuration Utility diskette, your diskette of .cfg files, or the configuration diskette(s) for any hardware option. Press <F7> to make a copy of or print the settings. If your computer is attached to a printer, you can print out the information or copy it to a file. Step 5: Save and Exit The Step 5: Save and Exit option allows you to save or cancel the configuration changes you have made. When you select the Step 5: Save and Exit option, follow the directions on the menu that displays. If you save your changes, the utility saves the new configuration in your system’s NVRAM and in a file on your EISA Configuration Utility diskette. Then, the utility automatically reboots your system. If you cancel your changes, you can remain in the utility to make other changes or exit the utility without saving any changes. Set Date and Set Time The Set Date and Set Time options reset the date and time maintained by your computer’s real-time clock (RTC), which uses NVRAM to keep the information current even when the system is turned off. You can also reset the date and time through the System Setup program as described in Chapter 4, “Using the System Setup Program.” NOTES: If your system is connected to a network, the Date and Time categories may reflect the time maintained by the network server, depending upon how the network is configured. In this case, changing the Date and Time categories on your system has no effect. Unless the EISA Configuration Utility is installed on your hard-disk drive, it is quicker to reset the date and time through the System Setup program. 5-68 Exit From This Utility The Exit From This Utility option allows you to exit from the EISA Configuration Utility and reboot your computer system. Advanced Menu The Advanced menu lets you lock or unlock cards in a configuration, view detailed information about the system, and maintain .sci files. To see the Advanced menu, press <F7> while in the Step 3: View and Edit Details menu. The following menu appears: Advanced menu Lock/unlock boards View additional system information menu Set verification mode menu Maintain SCI files menu Highlight the menu category you want, and press <Enter>. Then follow the online instructions. The following subsections describe each category. Lock/Unlock Boards When you lock an expansion card, the EISA Configuration Utility cannot change the resources allocated to that card. Unlocking the card allows the system to change the resources automatically as new cards are added. The default setting for the Lock/Unlock Boards category is Unlocked. Dell recommends that you keep your cards unlocked so that the EISA Configuration Utility can do its job properly. Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide View Additional System Information Menu The EISA Configuration Utility contains detailed information about the system board, the EISA and ISA expansion cards installed in your computer, and the used and available resources. The options for the View Additional System Information Menu category are: • • • • Board Specifications System Specifications Used Resources Available Resources The Used Resources and Available Resources options contain detailed information about resources such as IRQs, DMA channels, and I/O ports, which may be useful if you need to resolve a resource conflict. Set Verification Mode Menu The settings for the Set Verification Mode Menu category are Automatic (the default) and Manual. When this category is set to Automatic, the EISA Configuration Utility automatically checks for resource conflicts and tries to resolve them. Unless you are technically knowledgeable, leave this category set to Automatic. Maintain SCI Files Menu Each time you use the EISA Configuration Utility to configure your system, the system configuration information is saved in a .sci file and in system memory. You should save the system configuration information to a backup file that can be used to restore the information if the .sci file is damaged or lost. The options for the Maintain SCI Files Menu category are Open (the default) and Save As. The Open option creates a backup file that overwrites the existing configuration. The Save As option allows you to select the filename under which you want the .sci file saved. Resolving Resource Conflicts to fail in resolving a resource conflict between two EISA expansion cards. If the EISA Configuration Utility fails to resolve the conflict, see Chapter 8, “Getting Help,” in the Diagnostics and Troubleshooting Guide for information on obtaining technical assistance. However, resource conflicts between ISA expansion cards are routine. If the Set Verification Mode menu category is set to Automatic, the EISA Configuration Utility tries to resolve the conflict. If the utility cannot resolve the conflict, the card you just installed is deactivated and the following message is displayed: Caution The last board added caused an unresolvable conflict in your computer’s configuration. This board has a ‘Deactivated’ status. You must remove this board or the one(s) it is in conflict with in order to save a correct configuration. If the caution message appears, press <Enter> to display a list of all cards installed in your computer. The deactivated card is enclosed by < > symbols. You can remove the card(s) with which it is in conflict, or change the resources on one or more cards. If you want to remove the card, press <Del> and follow the online instructions. Remove the card from your computer when the utility prompts you to do so. (For instructions, see “Removing an Expansion Card” in Chapter 7.) If you remove the card(s) with which the new card is in conflict, or if you want to change the resources of one or more cards, use the procedure described in the next subsection. NOTE: Locked cards may cause resource conflicts. To unlock a card, use the following procedure: 1. Press <F7> in the Step 3: View or Edit Details menu (from the Steps in Configuring Your Computer menu). 2. Select Lock/Unlock Boards and press <Enter>. 3.

The following categories appear on the EISA System Board Options screen (see Figure 5-1) only if you press <Ctrl><a> at the Welcome screen when you start the EISA Configuration Utility: Modeling Mode • • • • • Modeling mode lets you create alternate .sci files to accommodate different hardware configurations. For example, if you regularly change the expansion cards or their arrangement in your computer, you can create and save a separate system configuration file for each configuration and load that file after changing the cards rather than having to create a new configuration file every time you change your configuration. 8 Bit I/O ISA Cycle Wait Control 16 Bit I/O ISA Cycle Wait Control Fail-safe Timer NMI Bus-master Timeout NMI Software Generated NMI These advanced options are intended for users who are technically knowledgeable. Do not change these options from their defaults if you do not understand how such a 5-70 NOTE: To use modeling mode, you must run the EISA Configuration Utility from the hard-disk drive. Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide To use the EISA Configuration Utility in modeling mode, start the utility from your hard-disk drive by typing at the operating system prompt and pressing <Enter>. (To use the advanced options in modeling mode, type at the operating system prompt and press <Enter>.) A dialog box appears with two options—Open As. . . (to load an existing system configuration file) and New (to create a new file). Highlight the option you want, and press <Enter>. The screen shows a list of Dell EISA systems. Choose the system you want to configure, and press <Enter>. At this point, you can modify or create a configuration file just as you would with the Configure Computer option. Modeling mode also provides access to advanced system board and expansion-card features, such as enabling or disabling NMIs (see “Advanced Menu” found earlier in this chapter). Ordinarily, you do not need to adjust these features unless a Dell service technician instructs you to do so. When you finish modifying or creating a system configuration file in modeling mode, select Step 5: Save and Exit from the Steps in Configuring Your Computer menu. A dialog box appears, offering two choices: to save the configuration file and restart the computer or to discard the configuration file and return to the Main Menu. If you choose to save the configuration file, you are prompted to type a filename for the new configuration file. Then you are prompted to type a description of the configuration file, which is stored with the configuration file. Using the Password Features CAUTION: The password features provide a basic level of security for the data on your system. However, they are not foolproof. If your data requires more security, it is your responsibility to obtain and use additional forms of protection, such as data encryption programs. Your Dell system is shipped to you with the supervisor and user password features ready to use but without passwords assigned. If system security is a concern, you should operate your system with password protection. You can assign a supervisor and/or user password through the EISA Configuration Utility (as described later in “Assigning a User Password” or “Assigning a Supervisor Password”) or through the System Setup program (as described in Chapter 4, “Using the System Setup Program”). Once you assign a supervisor and/or user password, only those who know the password(s) have full use of the system. NOTE: You can also use the System Setup program to assign, change, or delete a user or supervisor password. See the appropriate sections in Chapter 4, “Using the System Setup Program,” for more information. How Password Security Works When a supervisor password is assigned and the Password On Boot category is set to Enabled, the system prompts you for the supervisor password every time you start or reboot your computer. After a supervisor password is assigned, the EISA Configuration Utility prompts you for the supervisor password if you select Configure Computer from the Main Menu. You must enter a supervisor password to be able to change any of the system configuration parameters. Entering a user password allows you to view, but not change any of the system configuration parameters. To delete or change an existing supervisor or user password, you must know the supervisor password. See “Deleting an Existing User Password” or “Deleting an Existing Supervisor Password” found later in this section for more information. NOTE: A user password can only be assigned after a supervisor password has been assigned. If you assign and then forget a password, you must remove the cover of the computer (which may require unlocking the computer’s keylock) and change a jumper setting to temporarily disable the password features (see “Disabling a Forgotten Password” found later in this section). CAUTION: If you leave your system running and unattended, anyone can access the data stored in your system even with a password assigned. To protect your system while it is running, you must use additional forms of protection, such as screensaver software protected by a password. Using the EISA Configuration Utility 5-71 You can use up to seven characters; character keys or blank spaces are acceptable. CAUTION: With the password features disabled, your system operates as if it did not contain password features. If you leave your system running and unattended without having a supervisor and/ or user password assigned or with the password features disabled, anyone can assign a supervisor and/or user password that will be unknown to you. To erase a character in your password, press the <Backspace> key. NOTES: The supervisor password feature recognizes keys without distinguishing between shifted and unshifted characters or uppercase and lowercase letters. For example, if you have an M in your password, the system recognizes either M or m as correct. Assigning or Changing a Supervisor Password Your system arrives with the Supervisor Password category set to Not Enabled. Use the following procedure to assign or change a supervisor password. NOTE: To quit the following procedure without assigning or changing a password, press the <Esc> key at any time. 1. 2. 3. 4. 6. Press <Enter>.

Do not remove the packing material until you are ready to install the option. CAUTION: See “Protecting Against Electrostatic Discharge” in the safety instructions at the front of this guide. Inside Your Computer In Figures 6-3 and 6-4, the computer cover is removed to provide interior views. These illustrations also identify features on the front and back of the computer. Refer to them to locate interior features and components discussed later in this guide. When you look inside your computer, note the direct current (DC) power cables coming from the power supply. These cables supply power to the system board, the externally accessible drives, and the internal hard-disk drives. Expansion cards obtain power through the system board. 6-78 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide The flat ribbon cables are the interface cables for internal drives. These interface cables are described in more detail in Chapter 8, “Installing Drives in the External Bays,” and Chapter 9, “Installing Drives in the Internal Bays.” The system board—the large, vertical printed circuit board at the right side of the chassis—holds the computer’s control circuitry and other electronic components. Hardware options are installed directly onto the system board in the Peripheral Component Interconnect (PCI) or Extended Industry-Standard Architecture (EISA) expansion-card connectors. The external drive bays provide space for up to three half-height drives—typically a diskette drive is installed in the top bay, a CD-ROM drive in the middle bay, and the bottom bay is reserved for an optional drive (often a tape drive for backing up data from the hard-disk drives). The internal drive bays provide space for up to three 3.5-inch small computer system interface (SCSI) hard-disk drives. Drives installed in the internal drive bays can be up to 1.6 inches high. During an installation procedure, you may be required to change a jumper or switch setting on the system board, on an expansion card, or on a drive.

Adding Memory The four DIMM sockets (shown in Figure 7-5) on the system board can accommodate 16 to 512 megabytes (MB) of dynamic random-access memory (DRAM). The PowerEdge 2100 systems use 72-bit, buffered, extended data output (EDO) DIMMs in these 168-pin sockets. Error checking and correction (ECC) is performed by the memory controller in the system board chip set. Figure 7-1 shows the location of the DIMM sockets on the system board. DIMM_D DIMM_C DIMM_B DIMM_A Figure 7-5. DIMMs and DIMM Sockets Installing System Board Options 7-89 Memory Upgrade Kits Your system is upgradable to 512 MB by installing combinations of 16-, 32-, and 128-MB DIMMs in the DIMM sockets. The DIMMs should be rated at 60 nanoseconds (ns) or faster. Memory upgrade kits can be purchased from Dell as needed. DIMM Installation Guidelines Starting with the socket nearest the system board’s PCI expansion-card connectors and working toward the center of the system board, the sockets are labeled “DIMM_A” through “DIMM_D” (Figure 7-5). When installing DIMMs in sockets, follow these guidelines: • Install a DIMM in socket DIMM_A before socket DIMM_B, socket DIMM_B before socket DIMM_C, and so on. • If you install different sizes of DIMMs, start with the largest (highest capacity) DIMM in socket DIMM_A and work toward DIMM_D with the smaller DIMMs. Table 7-1 illustrates these guidelines by listing sample memory configurations. NOTE: The maximum memory supported in PowerEdge 2100 systems is 512 MB. 7-90 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Installing System Board Options 7-91 Table 7-1.

CAUTION: See “Protecting Against Electrostatic Discharge” in the safety instructions at the front of this guide. 7-92 Remove the system board assembly according to the instructions in “Removing the System Board Assembly” in Chapter 6. Lay the system board assembly on a flat work surface so you can easily access the DIMM sockets. 3. Determine the DIMM sockets into which you will install or replace DIMMs. See the previous subsection, “DIMM Installation Guidelines.” Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide 4. Follow the instructions in “Installing a DIMM” or “Removing a DIMM,” as appropriate, later in this section. 5. 6. “Using the EISA Configuration Utility,” for instructions on running the utility and saving the configuration. Install or replace the DIMMs as necessary to reach the desired memory total. 9. Replace the system board according to the instructions in “Replacing the System Board Assembly” in Chapter 6. Replace the computer cover according to the instructions in “Replacing the Computer Cover” in Chapter 6, reconnect your computer and peripherals to their power sources, and turn them on. After the computer completes the power-on self-test (POST) routine, it runs a memory test that displays the new memory total, which includes all newly installed memory. The system detects that the new memory does not match the system configuration information, which is stored in nonvolatile random-access memory (NVRAM), and generates the following error message: System memory size has changed — Run Configuration Utility See the chapter titled “Running the Diskette-Based Diagnostics” in your Diagnostics and Troubleshooting Guide for information on running the memory diagnostics. Installing a DIMM NOTE: The following procedure assumes that the system board assembly has been removed from the computer and is laying on a flat work surface. See “Removing and Replacing the System Board Assembly” in Chapter 6. Install DIMMs starting with socket DIMM_A, located nearest the PCI expansion-card connector, and working toward socket DIMM_D, nearest the center of the system board. If a DIMM is already installed in the socket you need, you must remove it. Follow the instructions in the next subsection, “Removing a DIMM,” if appropriate.) Use the following procedure to install a DIMM: 1. Press the ejectors on the DIMM socket down and outward as shown in Figure 7-6 to allow the DIMM to be inserted in the socket. 2. Align the DIMM’s edge connector with the slot in the center of the DIMM socket, and insert the DIMM in the socket. Press F1 to resume, F2 to Setup 7. Press <F2> (when prompted while the computer is booting) to enter the System Setup program, and check the Extended Memory category on the main menu of the System Setup screens. The card-edge connector on the DIMM is keyed so that the DIMM can only be installed in the socket in one way (Figure 7-6). The system should have already changed the value of the Extended Memory category to reflect the newly installed memory. Verify the new total. NOTE: If the memory total is incorrect, turn off your computer and peripherals and disconnect them from their power sources. Remove the computer cover and system board, and check all the installed DIMMs to make sure they are seated properly in their sockets. Then repeat steps 6 and 7. 8. Enter the EISA Configuration Utility. Then save the configuration and exit the utility. When the Extended Memory total is correct, run the diskette-based diagnostics to test all installed DIMMs. 3. Press down on the two outer edges of the DIMM with your thumbs while pulling up on the ejectors with your index fingers to lock the DIMM into the socket. When the DIMM is properly seated in the socket, the ejectors on the DIMM socket should align with the ejectors on the other DIMM sockets. Running the EISA Configuration Utility and saving the configuration is required for the system to recognize the newly installed DIMMs. See Chapter 5, Installing System Board Options 7-93 Installing a Microprocessor Upgrade The microprocessor is installed in a zero insertion force (ZIF) socket on the system board to allow you to easily upgrade your system with a more powerful microprocessor as your computing needs increase. Use the following procedure to remove the old microprocessor and install the upgrade. 2. cutout 1. Figure 7-6. Installing a DIMM 4.

CAUTION: Positioning the microprocessor chip incorrectly in the socket can permanently damage the chip and the computer when you turn on the system. Figure 7-11. Installing the Microprocessor Chip If the release lever on the microprocessor socket is not all the way up, move it to that position now. With the pin-1 corners of chip and socket aligned, align the pins on the chip with the holes in the socket. Set the chip lightly in the socket and make sure all pins are headed into the correct holes. Because your system uses a ZIF microprocessor socket, there is no need to use force (which could bend the pins if the chip is misaligned). When the chip is positioned correctly, it should drop down into the socket with minimal pressure. 9. Place the new heat sink (with its bonded thermal interface pad) on top of the microprocessor chip (see Figure 7-12). CAUTION: When placing the microprocessor chip in the socket, be sure that all of the pins go into the corresponding holes on all sides of the socket.

Then press down on the folded end of the clip to snap the clip over the tab on the back of the socket. 11. Change the microprocessor speed jumper setting to correspond to the new microprocessor’s operating frequency. The microprocessor speed jumper should be set for the installed microprocessor’s rated internal speed. For example, for a 200-megahertz (MHz) Intel Pentium Pro processor, a jumper plug should be installed As the system boots, it detects the presence of the new microprocessor and automatically changes the system configuration information in the System Setup program. 18. Enter the System Setup program, and confirm that the Microprocessor category correctly identifies the installed microprocessor. See Chapter 4, “Using the System Setup Program.” 19. Run the diskette-based Dell diagnostics to verify that the new microprocessor is operating correctly. See your Diagnostics and Troubleshooting Guide for information on running the diagnostics and troubleshooting any problems that may occur. Installing System Board Options 7-97 Replacing the System Battery The 3-V lithium backup battery (see Figure 7-13), mounted in the BATTERY socket on the system board (Figure 7-1), maintains system configuration, date, and time information in a special section of memory when the system is turned off and disconnected from alternating current (AC) power. battery BATTERY socket If you leave your system disconnected from AC power for long periods of time (for weeks or months), the NVRAM may lose its system configuration information. This situation is not caused by a defective battery. You can operate your system without a battery; however, the system configuration information is erased each time you turn off the computer and disconnect it from AC power. In this case, you must enter the System Setup program and reset the configuration options each time you boot your system until you can replace the battery. Use the following procedure to replace the computer battery: 1. If you have not already done so, make a copy of or print your system configuration information in the System Setup program. If the settings are lost while replacing the battery, refer to your written or printed copy to restore the correct settings. See Chapter 4, “Using the System Setup Program,” for instructions.

Standard PowerEdge 2100 systems include a diskette drive in the top bay and a CD-ROM drive in the middle bay. A drive of your choice can be installed in the lower bay. Because you may need to tailor a drive to work with your system, certain installation instructions in this chapter refer you to the documentation that came with the drive for information on changing jumper settings. The diskette drive is controlled by the system board’s built-in diskette controller. The CD-ROM drive provided with the system and an additional small computer system interface (SCSI) drive (if installed in the lower bay) are controlled by the system board’s built-in SCSI controller. Jumpers NOTE: Dell PowerEdge 2100 systems support only SCSI hard-disk drives in the internal drive bays. For more information, see Chapter 9, “Installing Drives in the Internal Bays.” Drives installed by Dell are configured to work with your system. However, you should check the documentation for the drive to verify that the jumpers are set correctly for your particular configuration, and make any necessary alterations. (For an explanation of jumpers, see “Jumpers” in Appendix B.) For example, when daisy-chaining two drives together, you may need to reconfigure one or both drives to differentiate between them for proper operation.

External Drive Bay Hardware 8-102 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Before You Begin In order to remove or install drives in the external bays, you must remove the computer cover and front bezel according to the instructions in “Removing the Computer Cover” and “Removing the Front Bezel” in Chapter 6. Removing and Replacing FrontPanel Inserts To protect the inside of the computer from foreign particles, a plastic front-panel insert covers each empty external drive bay. Additionally, each empty drive bay is covered by a metal insert to maintain the necessary electromagnetic interference (EMI) shielding for the chassis. Before you install a drive in an empty bay, you must first remove the plastic and metal inserts. Whenever you remove a drive, be sure to replace the metal insert on the chassis and then replace the plastic insert in the front bezel to cover the empty bay. Removing and Replacing Plastic Inserts To remove the plastic insert for a drive bay you intend to use, first remove the front bezel as instructed in “Removing the Front Bezel” in Chapter 6. Then, facing the inside of the front bezel, grasp the front bezel with both hands and place your fingers on the outside of the front-bezel insert (indicated by the two arrows in Figure 8-2). Push on the outside of the front-bezel insert while twisting the sides of the front bezel outward until the front-bezel insert is released. Figure 8-2. Removing a Plastic Insert To replace a front-panel insert, position the insert over the bay opening from the inside of the front bezel and carefully press the insert into place. A tab on each side of the insert snaps into a corresponding latch on the inside of the front bezel. Removing Metal Inserts To remove the metal insert for a drive bay you intend to use, first remove the front bezel as instructed in “Removing the Front Bezel” in Chapter 6. Next, remove the retaining screw at the right end of the metal insert (see Figure 8-3), and then pivot the metal insert out and slide it to the right.

Removing a Metal Insert Connecting the Drive interface connector This section describes the power input connectors and interface connectors on the back of most drives. Figure 8-4 shows the 4-pin power input connector, where you connect a direct current (DC) power cable from the power supply. The power connectors are keyed to avoid incorrect insertion; do not force two connectors together if they do not fit properly. header connector key (cut-off pin) Figure 8-5. Header Connector Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a filled-in hole on the other connector. Keying ensures that the pin-1 wire in the cable (indicated by the colored strip along one edge of the cable) goes to the pin-1 ends of the connectors on both ends. 8-104 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide A header connector is usually keyed by the omission of one of its pins with the corresponding hole filled in on the cable connector, as shown in Figure 8-5. CAUTION: When connecting an interface cable, match the colored strip to the pin-1 end of the connector. Reversing the cable prevents the drive from operating and could damage the controller, the drive, or both. Figure 8-6 identifies the types of DC power cables coming from the computer’s power supply. Before connecting a drive to a power cable, refer to Figure 8-6 to identify the correct cable connector to use for the drive. 5.25-inch drive connector Bays The external drive bays (Figure 8-7) can hold up to three half-height devices. A diskette drive is standard in the top bay and a CD-ROM drive is standard in the middle bay.

Installing Diskette Drives That Use the Diskette Drive Controller To install a 5.25- or 3.5-inch diskette drive that uses the built-in diskette drive controller, follow these steps: 1. CAUTION: See “Protecting Against Electrostatic Discharge” in the safety instructions at the front of this guide. Prepare the drive for installation. Ground yourself by touching an unpainted metal surface on the back of the computer, unpack the drive, and compare the jumper settings with those in the drive documentation. Change any settings necessary for your system’s configuration. If the drive does not already have drive rails attached, attach a drive rail to each side of the drive. Orient the drive rails as shown in Figure 8-9. Secure each drive rail to the drive with a screw in the first (from the front) and third slotted screw holes on the drive rail as shown in Figure 8-9. Remove the computer cover and front bezel according to the instructions in “Removing the Computer Cover” and “Removing the Front Bezel” in Chapter 6. 3. Slide the new drive into its bay until it snaps securely into place. If necessary, you can adjust drive alignment by repositioning one or both rails. 4. Connect a DC power cable and the diskette interface cable to the back of the drive (see Figure 8-1). If other installed drives are in the way, you can temporarily move them out of the way. Press in on the plastic drive rails at the front of the bay to disengage a drive; then slide the drive toward the front of the chassis (see Figure 8-8). Refer to Figure 8-6 to determine the appropriate DC power cable connector to use, depending on the type of drive. Plug the DC power cable into the 4-pin power input connector on the back of the drive. 8-106 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Refer to Figure 8-8 to determine the appropriate connector to use on the diskette drive interface cable. CAUTION: Check the cable orientation— match the colored strip to the pin-1 end of the connector. Installing SCSI Drives in the External Bays 1. Ground yourself by touching an unpainted metal surface on the back of the computer, unpack the drive, and compare the jumper and switch settings with those in the drive documentation. (See “SCSI Configuration Guidelines” in Chapter 9 for information on setting the drive’s SCSI identification (ID) number and enabling termination, if required). Change any settings necessary for your system’s configuration. Press the interface cable connector firmly onto the drive’s connector. Be sure that the interface cable is routed through the slot in the upper chassis rail to prevent interference with other devices. If you moved other drives at the beginning of this step, snap them back into place. 5. Check all cable connections that may have been loosened during this procedure. Arrange cables so they will not catch on the computer cover or block the airflow of the fans or cooling vents. 6. If a front-panel insert on the front bezel blocks the bay in which you installed the drive, remove the insert (see “Removing and Replacing FrontPanel Inserts” found earlier in this chapter). 7. If the drive does not already have drive rails attached, attach a drive rail to each side of the drive. Orient the drive rails as shown in Figure 8-9. Secure each drive rail to the drive with a screw in the first and third slotted screw holes on the drive rail as shown in Figure 8-9. 2. Replace the computer cover and front bezel according to the instructions in “Replacing the Computer Cover” and “Replacing the Front Bezel” in Chapter 6. 8. Reconnect your computer and peripherals to their power sources, and turn them on. 9. Update your system configuration information. Enter the System Setup program, and if you installed a diskette drive, update the appropriate Diskette Drive category (A or B) to reflect the size and capacity of your new diskette drive. 10. Verify correct operation of your system. See the chapter titled “Running the Diskette-Based Diagnostics” in your Diagnostics and Troubleshooting Guide for information on running the diskette-based diagnostics. Test the drive by running all the subtests in the Diskette Drive Test Group of the diskettebased diagnostics. Prepare the drive for installation. Remove the computer cover and front bezel according to the instructions in “Removing the Computer Cover” and “Removing the Front Bezel” in Chapter 6. CAUTION: See “Protecting Against Electrostatic Discharge” in the safety instructions at the front of this guide. 3. Slide the new drive into its bay until it snaps securely into place. If necessary, you can adjust drive alignment by repositioning one or both rails. 4. Connect a DC power cable and one of the connectors on the SCSI interface cable to the back of the drive (see Figure 8-1). Refer to Figure 8-6 to determine the appropriate DC power cable connector to use, depending on the type of drive. Plug the DC power cable into the 4-pin power input connector on the back of the drive. Use either of the two SCSI connectors nearest the system board connector on the SCSI interface cable (see Figure 9-2). Installing Drives in the External Bays 8-107 NOTE: You will need a 68-pin to 50-pin adapter to connect the SCSI cable to the narrow (50-pin) connector on the CD-ROM or tape drive (Figure 8-10). Press the interface cable connector firmly onto the adapter and the adapter firmly onto the drive’s connector. If you moved other drives at the beginning of this step, snap them back into place. Installing an Optional SCSI Controller for the External Bay SCSI Drives Performance of the SCSI hard-disk drives in the internal bays can be increased by adding an optional SCSI controller card to control the CD-ROM drive and any other SCSI device installed in the external bays. The optional Adaptec AHA-2940 SCSI controller is available from Dell in a kit that includes an interface cable with 50-pin connectors for narrow SCSI devices. Use the following procedure to install an optional SCSI controller card for the SCSI devices in the external bays. 1. Refer to the documentation accompanying the SCSI controller card. If the card incorporates jumpers that must be set to work with your system, verify or change the settings as necessary. Figure 8-10. 68-Pin to 50-Pin Adapter 5. Check all cable connections that may have been loosened during this procedure. Arrange cables so they will not catch on the computer cover or block the airflow of the fans or cooling vents. Enable termination for the controller according to the instructions in “SCSI Configuration Guidelines” in Chapter 9. 2. 6. If a front-panel insert on the front bezel blocks the bay in which you installed the drive, remove the insert (see “Removing and Replacing FrontPanel Inserts” found earlier in this chapter). 7. Replace the computer cover and front bezel according to the instructions in “Replacing the Computer Cover” and “Replacing the Front Bezel” in Chapter 6. 8. Reconnect your computer and peripherals to their power sources, and turn them on. 3. 9. Verify correct operation of your system. 4.

Reconnect your computer and peripherals to their power sources, and turn them on. If you have more than one SCSI device in the external bays, you should connect the end connector on the interface cable to the CD-ROM drive and enable termination for the CD-ROM drive. See “SCSI Configuration Guidelines,” in Chapter 9 for instructions on enabling termination. 8. Verify correct operation of your system. Refer to the chapter titled “Running the DisketteBased Diagnostics” in your Diagnostics and Troubleshooting Guide, and run the appropriate tests in the SCSI Devices Test Group to verify that the new SCSI controller is functioning correctly. Replace the computer cover according to the instructions in “Replacing the Computer Cover” in Chapter 6. Installing Drives in the External Bays 8-109 8-110 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Chapter 9 Installing Drives in the Internal Bays T his chapter describes how to install and configure small computer system interface (SCSI) hard-disk drives in the internal drive bays. Up to three 1.6-inch SCSI hard-disk drives can be installed in the internal hard-disk drive bays. NOTE: You should install only SCSI hard-disk drives in the internal drive bays; install SCSI CD-ROM and tape drives in the external drive bays. Dell PowerEdge 2100 systems have a built-in Adaptec AIC-7880 ultra wide (fast-20) SCSI-2 controller on the system board, accessible via a 68-pin SCSI connector on the system board. This single-channel SCSI controller features active termination, which provides for better signal quality at fast SCSI-2 speeds. You can attach a variety of SCSI devices (hard-disk drives, tape drives, and so on) to the built-in SCSI controller, which configures all devices attached to it as one subsystem—not as independent devices. NOTE: If you choose to install an additional or alternative SCSI controller card, install the card as described in “Installing an Expansion Card” in Chapter 7. Before installing the card, be sure to check the documentation that accompanied it for information on configuring the card. When installing and cabling the devices, use the general SCSI configuration guidelines provided in the following section; check the documentation that accompanied your SCSI controller card and/or your SCSI devices for any additional configuration requirements. SCSI Configuration Guidelines Although SCSI devices are installed essentially the same way as other devices, their configuration requirements are different. To configure your SCSI subsystem, follow the general guidelines offered in the following subsections. SCSI ID Numbers Each device attached to the SCSI host adapter must have a unique SCSI identification (ID) number from 0 to 15. NOTE: Any narrow SCSI devices installed in the external drive bays will require SCSI ID numbers less than 7. When SCSI devices are shipped from Dell, the default SCSI ID numbers are assigned as follows: • The computer’s built-in SCSI controller is configured through the basic input/output system (BIOS) as SCSI ID 7 (the default ID number for a host adapter) if the system includes a CD-ROM or tape drive. NOTE: If only wide SCSI hard-disk drives are connected to the built-in SCSI controller (no CD-ROM or tape drives), it may be configured as SCSI ID 15. • A SCSI CD-ROM drive (installed in an external bay) is configured as SCSI ID 5. • A SCSI tape drive (if installed) is configured as SCSI ID 6. • The drive you intend to use as your boot device should be configured as SCSI ID 0. You can configure any additional hard-disk drives to any of the stillavailable SCSI ID numbers. • If Dell installs additional SCSI hard-disk drives in the system, they will be configured as SCSI ID 1 and SCSI ID 2. NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the cable in order by ID number. Installing Drives in the Internal Bays 9-111 Device Termination termination jumper Before installing SCSI devices, you must configure the termination on the device(s) and for the built-in SCSI controller according to the guidelines listed in the following text. SCSI logic requires that termination be enabled for the two devices at opposite ends of the SCSI chain and disabled for all devices in between. To that end, regardless of whether you are installing internal or external devices, use the following guidelines: • CD-ROM drive The built-in SCSI controller has active termination—no action is required. • Termination is set on the SCSI hard-disk drive installed in the left bay of the internal drive bays when the drive is installed by Dell. Termination should be disabled on any other drives installed in the internal bays. Figure 9-1 shows where the termination jumper should be located on the Dell-supplied 2-gigabyte (GB) and 4-GB SCSI hard-disk drives for the PowerEdge 2100 system. • If you install an optional SCSI controller card to control the CD-ROM drive and any other SCSI device in the external bays, you must enable termination for the SCSI controller card and the SCSI device at the end of the interface cable (preferably the CD-ROM drive). See the documentation that came with your SCSI controller card for instructions. To enable termination for the CD-ROM drive, place a jumper on the pins on the back of the CD-ROM drive as shown in Figure 9-1. CAUTION: When you install or remove termination jumpers, do not move or remove any other jumpers installed on the drives. 9-112 termination jumper 4-GB hard-disk drive termination jumper 2-GB hard-disk drive (bottom view) Figure 9-1. SCSI Termination Jumper Locations Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Configuring the Boot Device If you plan to boot your system from a hard-disk drive, the drive must be attached to the primary (or boot) controller or built-in SCSI controller. You can select as the primary controller either the built-in SCSI controller or an optional controller installed in an expansion slot through the Advanced menu in System Setup. Within the Advanced menu, the PCI Scan Sequence option allows you to select either the built-in SCSI controller or a controller in an expansion slot as the primary controller. SCSI Cable Figure 9-2 shows the SCSI cable provided with the Dell PowerEdge 2100 system. CAUTION: Dell recommends that you use only SCSI cables purchased from Dell. SCSI cables purchased elsewhere are not guaranteed to work reliably with PowerEdge 2100 systems. internal bay connectors (3) external bay connectors (2) built-in SCSI controller connector Figure 9-2. SCSI Interface Cable The cable shown in Figure 9-2 has six 68-pin connectors: • The connector at one end of the cable farthest from the other connectors attaches to the SCSI controller connector (SCSI) on the system board. • The two connectors in the middle of the cable attach to SCSI devices in the external drive bays via 68-pin to 50-pin adapters. • The three connectors at the other end of the cable attach to the drives in the internal hard-disk drive cage. The connector on the end of the cable should be attached to the leftmost drive in the internal harddisk drive cage since the termination jumpers on this drive can be accessed without removing the drive cage.

Technical Specifications A-119 A-120 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide Appendix B Hardware Configuration Features T his appendix provides specific information about the jumpers on the system board, the connectors and sockets Jumpers on the system board, and the input/output (I/O) ports and connectors on the back panel of the computer. It also provides some basic information on jumpers. A jumper is a small block on the system board with two or more pins emerging from it. Jumpers—A General Explanation A plastic plug containing a wire fits down over the pins. The wire connects the pins and creates a circuit. Jumpers provide a convenient and reversible way of reconfiguring the circuitry on a printed circuit board. When reconfiguring the system, you may need to change jumper settings on the system board; you may also need to change jumper settings on expansion cards or on drives. To change a jumper setting, pull the plug off its pin(s) and carefully fit it down onto the pin(s) indicated. CAUTION: Make sure your system is turned off before you change a jumper setting. Otherwise, damage to your system or unpredictable results may occur. A jumper is referred to as open or unjumpered when the plug is pushed down over only one pin or if there is no plug at all. When the plug is pushed down over two pins, the jumper is referred to as jumpered. The jumper setting is often shown in text as two numbers, such as 1-2. The number 1 is printed on the circuit board so that you can identify each pin number based on the location of pin 1. Figure B-1 shows the location and default settings of the jumper blocks on the system board. See Table B-1 for the designations, default settings, and functions of the system board’s jumpers.

B-124 Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide I/O Ports and Connectors The I/O ports and connectors on the back panel of the computer are the gateways through which the computer system communicates with external devices, such as a keyboard, mouse, printer, and monitor. Figure B-2 identifies the I/O ports and connectors for your system. Serial and Parallel Ports The two built-in serial ports use 9-pin D-subminiature connectors on the back panel. These ports support devices such as external modems, printers, plotters, and mice that require serial data transmission (the transmission of data one bit at a time over one line). Most software uses the term COM (for COMmunications) plus a number to designate a serial port (for example, COM1 or COM2). The default designations of your computer’s builtin serial ports are COM1 and COM2. COM1 is the bottom connector; COM2 is on the top. The built-in parallel port uses a 25-pin D-subminiature connector on the computer’s back panel. This I/O port sends data in parallel format (where eight data bits, or one byte, are sent simultaneously over eight separate lines in a single cable). The parallel port is used primarily for printers. KYBD (left) MOUSE (right) SERIAL COM 1(left) SERIAL COM 2 (right) PARALLEL LPT 1 Most software uses the term LPT (for Line PrinTer) plus a number to designate a parallel port (for example, LPT1). The default designation of the computer’s built-in parallel port is LPT1. Port designations are used, for example, in software installation procedures that include a step in which you identify the port to which a printer is attached, thus telling the software where to send its output. (An incorrect designation prevents the printer from printing or causes scrambled print.) VIDEO JVGA Figure B-2. I/O Ports and Connectors Hardware Configuration Features B-125 Both the new and the remapped COM ports share the same interrupt request (IRQ) setting, as follows: COM1, COM3: IRQ4 (shared setting) COM2, COM4: IRQ3 (shared setting) These COM ports have the following I/O address settings: COM1: COM2: COM3: COM4: 3F8h 2F8h 3E8h 2E8h For example, if you add an internal modem card with a port configured as COM1, the computer then sees logical COM1 as the address on the modem card. It automatically remaps the built-in serial port that was designated as COM1 to COM3, which shares the COM1 IRQ setting. (Note that when you have two COM ports sharing an IRQ setting, you can use either port as necessary but you may not be able to use them both at the same time.) If you install one or more expansion cards with serial ports designated as COM1 and COM3, the corresponding built-in serial port is disabled, as described in “Serial Port 1” and “Serial Port 2” in Chapter 4. Before adding a card that remaps the COM ports, check the documentation that accompanied your software to make sure that the software can be mapped to the new COM port designation. To avoid autoconfiguration, you may be able to reset jumpers on the expansion card so that its port designation changes to the next available COM number, leaving the designation for the built-in port as is. Alternatively, you can disable the built-in ports through the System Setup program. The documentation for your expansion card should provide the card’s B-126 The built-in parallel port has autoconfiguration capability through the System Setup program. That is, if you set the parallel port to its automatic configuration and add an expansion card containing a port configured as LPT1 (IRQ7, I/O address 378h), the system automatically remaps the built-in parallel port to its secondary address (IRQ5, I/O address 278h). If the secondary port address is already being used, the built-in parallel port is turned off. For more information, see “Parallel Port” in Chapter 4. For general information on how your operating system handles serial and parallel ports as well as for more detailed command procedures, see your operating system documentation. Serial Port Connectors If you reconfigure your hardware, you may need pin number and signal information for the serial port connectors. Figure B-3 illustrates the pin numbers for the serial port connectors, and Table B-3 lists and defines the pin assignments and interface signals for the serial port connectors. 1—5 The computer system has an autoconfiguration capability for the serial ports. This feature lets you add an expansion card containing a serial port that has the same designation as one of the built-in ports, without having to reconfigure the card. When the computer detects the duplicate serial port on the expansion card, it remaps (reassigns) the built-in port to the next available port designation. default I/O address and allowable IRQ settings. It should also provide instructions for readdressing the port and changing the IRQ setting if necessary. 6— 9 Adding an Expansion Card Containing Serial or Parallel Ports Figure B-3.

Pin Numbers for the Parallel Port Connector Keyboard and Mouse Connectors The system uses a Personal System/2 (PS/2)-style keyboard and supports a PS/2-compatible mouse. Cables from both devices attach to 6-pin, miniature Deutsche Industrie Norm (DIN) connectors on the back panel of your computer. The keyboard connector is on the bottom; the mouse connector is on the top. A PS/2-compatible mouse works identically to an industrystandard serial mouse or bus mouse except that it has its own dedicated connector, which frees up both serial ports and does not require an expansion card. Circuitry inside the Hardware Configuration Features B-127 mouse detects the movement of a small ball and relays the direction to the computer. Mouse driver software can give the mouse priority with the microprocessor by issuing IRQ12 whenever a new mouse movement is made. The driver software also passes along the mouse data to the application program that is in control.

This appendix contains maintenance procedures that you should perform regularly. Data Preservation Everyone inadvertently deletes files at one time or another. Also, hard-disk drives can fail after extended use, so it is not a question of whether you will eventually lose data, but when. To avoid such loss of data, you should regularly make backup copies of all hard-disk drive files. Frequent, regular backups are a must for anyone using a hard-disk drive. Scheduling Backups Backup Devices Tape drives are fast, convenient, and affordable devices that can back up data at rates of up to 1.6 megabytes per second (MB/sec) (sustained, with data compression) and can often run unattended. Dell offers tape drives with storage capacities in the range of 4 gigabytes (GB) to 24 GB per tape cartridge and recommends these drives and their associated backup software for use as system backup devices. Recovering Data Some hard-disk drive failures are recoverable. In these cases you may be able to recover all lost data if the proper utility software is available. Even losses such as accidentally deleted files or accidental reformatting of a hard-disk drive can be reversed with these utilities. The frequency with which backups should be made depends on the amount of storage space on a hard-disk drive and the volatility of the data contained on the drive. Heavily used systems require more frequent backups than systems in which files are seldom changed. If the computer system is running MS-DOS, many apparent data loss problems are due to corruption or erasure of the hard-disk drive’s master boot record (MBR), MS-DOS boot sector, or file allocation table (FAT). That is, accidental deletion of files or accidental reformatting of the hard-disk drive alters the MS-DOS boot sector, the FAT, and the root directory. Dell recommends that you back up the hard-disk drive at least once a week, with a daily backup of those files known to have been changed. Following these guidelines ensures the loss of no more than a day’s work in the event of a hard-disk drive failure or if you inadvertently delete one or more important files. However, such accidents do not actually erase the contents of the hard-disk drive files until new data is written to the sectors containing these files. With the appropriate recovery utility, the data stored in these areas can often be restored, meaning that you can recover most, if not all, of the data. As further insurance against data losses, you should keep duplicate copies of the weekly and monthly backups at an off-site location. Doing this ensures that you lose no more than a week’s work, even if one of the on-site backups becomes corrupted. Unlike using the format command on a hard-disk drive, using format on a diskette completely erases all the data on the diskette unless you use the diskette format program included in the Mace Utilities. Maintaining the System C-131 For a complete description of data recovery procedures and the software needed to perform them, see The Paul Mace Guide to Data Recovery, published by Brady. • A nonabrasive diskette-drive head-cleaning kit — Dell recommends that you use a kit that contains pretreated diskettes in individually sealed packages. These kits ensure that the cleaning solution is applied evenly over the entire diskette-drive head surface, and they prevent contamination of the heads by exposure to foreign substances. • A small vacuum cleaner with a brush attachment — Use the vacuum cleaner to remove dust and dirt from the exterior of the computer and keyboard. Cleaning System Components An exhaust fan in the power supply cools the power supply and computer by drawing air in through various openings in the computer and blowing it out the back. However, the fan also draws dust and other particles into the computer, causing contaminant buildup, which results in an increase in the system’s internal temperature and interferes with the operation of various system components. To avoid these conditions, Dell recommends keeping your work environment clean to reduce the amount of dust and dirt around the computer, thereby reducing the amount of contaminants drawn into the computer by the power supply fan. In particular, you should keep the exterior of your computer and monitor clean, and you should use a commercially available diskette-drive headcleaning kit to remove contaminants inside your diskette drives. Cleaning the Computer, Monitor, and Keyboard Exteriors A conventional monitor or keyboard cover minimizes the accumulation of dust and other debris inside the monitor and keyboard when they are not in use. Also, commercially available keyboard membrane covers make it possible to use the keyboard while providing protection against foreign particles. However, regardless of any protective covers, the monitor and keyboard must be cleaned occasionally. To clean the exterior of the computer, monitor, and keyboard, follow these steps: 1. Turn off the computer, monitor, and any other attached peripherals, and disconnect them from their power sources. 2. Use a vacuum cleaner to remove any dust from the slots and holes on the computer and between the keys on the keyboard. 3. Moisten a soft cleaning cloth with a solution of three parts water and one part liquid dishwashing detergent. Recommended Tools and Accessories Dell recommends that you use the following tools and accessories when you clean the computer: • • • A wrist grounding strap — The proper use of a wrist grounding strap reduces the effect of electrostatic discharge (ESD), which can damage certain computer components. To use a wrist grounding strap, place the strap around your wrist and attach the other end of the strap to an unpainted metal surface on the chassis, such as the power supply’s fan guard, that is connected to chassis ground. A liquid dishwashing detergent — Use a mixture of one part liquid dishwashing detergent and three parts water to clean the exterior of the computer, monitor, and keyboard. You can also add fabric softener to produce an antistatic solution that prevents dust from being attracted to the monitor screen. A soft, lint-free cleaning cloth — Moisten the cleaning cloth with the dishwashing detergent solution to clean the exterior of the computer system. C-132 Do not soak the cloth in the solution; you must not let the solution drip inside the computer or keyboard. 4. Use the moistened cloth to wipe the computer cover, the keyboard, and the exterior of the monitor, including the screen. Cleaning Drives You can clean the heads of your diskette drives by using a commercially available diskette-drive head-cleaning kit. These kits include diskettes pretreated with a chemical solution to nonabrasively remove contaminants that accumulate on the drive heads during normal operation. Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide If the kit does not contain instructions, insert one of the pretreated diskettes into a diskette drive and turn on the system. After 20 or 30 seconds, remove the diskette from the drive. Repeat this procedure for each diskette drive in the computer. CAUTION: Do not attempt to clean drive heads with a swab. You may accidentally misalign the heads, rendering the drive inoperable. Environmental Factors This section discusses various environmental factors that can adversely affect system performance and longevity. Temperature Temperature extremes can cause a variety of problems, including premature aging and failure of chips or mechanical failure of devices. Extreme temperature fluctuations can cause chips to become loose in their sockets and can cause expansion and contraction of disk drive platters, resulting in read or write data errors. When you perform a low-level format operation on a hard-disk drive, it is important to ensure that the drive’s surrounding temperature is at or near the temperature at which the drive will be operated. Failure to do so can result in relocation of the tracks on the disk platters. To minimize the negative effects of temperature on system performance, follow these guidelines: • • • Ensure that the system is operated in an environment no colder than 10° Celsius (C) (50° Fahrenheit [F]) or hotter than 35°C (95°F). Ensure that the system has adequate ventilation. Do not place it within a closed-in wall unit or on top of cloth material, which can act as insulation. Do not place it where it will receive direct sunlight, particularly in the afternoon. Do not place it next to a heat source of any kind, including heating vents during winter. Make sure that all slots and openings on the computer remain unobstructed, especially the fan guard on the back of the computer. • Clean the system at regular intervals to avoid any buildup of dust and debris, which can cause a system to overheat. • If the system is exposed to abnormally cold temperatures, allow a 15-minute warm-up period after it is turned on before attempting to read from or write to the hard-disk drive. • If intermittent system failures are noticed, try reseating any socketed chips, which might have become loose due to temperature fluctuations. Humidity High-humidity conditions can cause moisture migration and penetration into the computer. This moisture can cause corrosion of internal components and degradation of properties such as electrical resistance, thermal conductivity, physical strength, and size. Extreme moisture buildup inside the computer can result in electrical shorts, which can cause serious damage to the computer. Each Dell system is rated to operate at 8 to 80 percent relative humidity, with a humidity gradation of 10 percent per hour. In storage, a Dell system can withstand from 8 to 95 percent relative humidity. Buildings in which climate is controlled by airconditioning in the warmer months and by heat during the colder months usually maintain an acceptable level of humidity for computer equipment. However, if a system is located in an unusually humid location, a dehumidifier can be used to maintain the humidity within an acceptable range. Altitude Operating a system at high altitude (low pressure) reduces the efficiency of forced and convection cooling and can result in electrical problems related to arcing and corona effects. This condition can also cause sealed components with internal pressure, such as electrolytic capacitors, to fail or perform at reduced efficiency. Each Dell system is rated to operate at altitudes from -16 to 3048 meters (m) (-50 to 10,000 feet [ft]) and can be stored at altitudes of -16 to 10,600 m (-50 to 35,000 ft). Maintaining the System C-133 Dust and Particles A clean operating environment can greatly reduce the negative effects of dust and other particles, which act as insulators and interfere with the operation of a system’s mechanical components. Also, in addition to regular cleaning, you should follow these guidelines to deter contamination of the computer equipment: • • • • Do not permit smoking anywhere near the system. • Close windows and outside doors to keep out airborne particles. Do not permit food or drink near the system. Use dust covers when the system is not in use. Keep all diskettes in a closed diskette box when not in use. Corrosion The oil from a person’s fingers or prolonged exposure to high temperature or humidity can corrode the gold-plated edge connectors and pin connectors on various devices in the computer. This corrosion on computer connectors is a gradual process that can eventually lead to intermittent failures of electrical circuits. To prevent corrosion, you should avoid touching contacts on boards and cards. Protecting the system from corrosive elements is especially important in moist and salty environments, which tend to promote corrosion. Also, as a further deterrent to corrosion, the system should not be used in extreme temperatures, as explained in “Temperature” discussed earlier in this appendix. ESD ESD results from the buildup of static electricity on the human body and certain other objects. This static electricity is often produced by simple movements such as walking across a carpet. ESD is a discharge of a static electrical charge, which occurs when a person whose body contains such a charge touches a component in the computer. This static discharge can cause components, especially chips, to fail. ESD is a problem particularly in dry environments where the relative humidity is below C-134 50 percent. To reduce the effects of ESD, you should observe the following guidelines: • When working inside the computer, wear a wrist grounding strap. If a wrist grounding strap is unavailable, touch an unpainted metal surface on the chassis periodically to neutralize any static charge. • If at all possible, stand on a concrete floor while working inside the computer. • Use an antistatic floor mat when working inside the computer. • If it is necessary to work in a carpeted area, spray the carpet with an antistatic spray and allow it to dry before beginning to work inside the computer. • Keep components in their antistatic packaging until they are installed. • Avoid wearing clothing made of wool or synthetic materials. Electromagnetic and Radio Frequency Interference Electromagnetic interference (EMI) and radio frequency interference (RFI) from a computer can adversely affect devices such as radio and television (TV) receivers operating near the computer. Radio frequencies emanating from a computer system can also interfere with cordless and low-power telephones. Conversely, RFI from highpower telephones can cause spurious characters to appear on the system’s monitor screen. RFI is defined as any EMI with a frequency above 10 kilohertz (kHz). This type of interference can travel from the computer to other devices through the alternating current (AC) power cable and power source or through the air like transmitted radio waves. The Federal Communications Commission (FCC) publishes specific regulations to limit the amount of EMI and RFI emitted by computing equipment. Each Dell system meets these FCC regulations. To reduce the possibility of EMI and RFI, follow these guidelines: • Operate the system only with the computer cover installed. Dell PowerEdge 2100/180 and 2100/200 Systems User’s Guide • Ensure that all expansion slots are covered either by a card-mounting bracket or by a metal filler bracket and that each drive bay has a drive and/or a metal insert installed. These brackets and metal inserts are available from Dell. • Ensure that the screws on all peripheral cable connectors are securely fastened to their corresponding connectors on the back of the computer. • Always use shielded cables with metal connector shells for attaching peripherals to the computer. To prevent the possibility of RFI from a computer affecting TV reception, follow these guidelines: 11 milliseconds (ms). In storage, the system can withstand shock pulses of 20 G with a velocity change of 1397 millimeters (mm) per second (55 inches per second). Excessive vibration can cause the same problems as mentioned earlier for shock, as well as cause components to become loose in their sockets or connectors. Systems can be subject to significant vibration when being transported by vehicle or when operated in an environment with machinery that causes vibration. Each Dell system, when operating, is designed to withstand 0.25 G (half-sine wave) at a sweep of 3 to 300 hertz (Hz) for 15 minutes. In storage, the system can withstand 0.5 G at 3 to 300 Hz for 15 minutes. • Keep any TV set at least 6 ft away from the computer system. • • • • Use cable TV when possible. Power Source Interruptions Use a directional outdoor TV antenna. • If interference occurs, rotate the computer or the TV set 90 degrees. Computer systems are especially sensitive to variations in voltage supplied by the AC power source. Overvoltage, undervoltage, and transients (or spikes) can erase data from memory or even cause components to fail. To protect against these types of problems, power cables should always be properly grounded and one or both of the following methods should be used: Attach line filters to the TV set. Use 75-ohm coaxial cable for the TV set rather than twin-lead antenna wire. • Use one of the power protection devices described in the following section, “Power Protection Devices.” • Place the system on a dedicated power circuit (rather than sharing a circuit with other heavy electrical equipment). In general, do not allow the system to share a circuit with any of the following: Magnetism Because they store data magnetically, diskettes and harddisk drives are extremely susceptible to the effects of magnetism. Diskettes should never be stored near magnetic sources such as the following: • • • • • Monitors — Kitchen appliances TV sets — Copier machines Printers — Air conditioners Telephones with real bells — Vacuum cleaners Fluorescent lights — Space heaters — Power tools Shock and Vibration — Teletype machines Excessive shock can damage the function, external appearance, and physical structure of a system. Each Dell system has been designed to operate properly after withstanding a minimum of six consecutively executed shock pulses in the positive and negative x, y, and z axes. Each shock pulse can measure up to 5 gravities (G) for up to — Adding machines — Laser printers — Facsimile machines — Any other motorized equipment Maintaining the System C-135 Besides these appliances, the greatest threat to a system’s supply of power are surges or blackouts caused by electrical storms. Whenever possible, turn off the computer and any peripherals and unplug them from their power sources during thunderstorms. If a blackout occurs—even a temporary one—while the system is turned on, turn off the system immediately and disconnect it from its power source. Leaving the system on may cause problems when the power is restored; all other appliances left on in the area can create large voltage spikes that can damage the system. Power Protection Devices A number of devices are available that protect against power problems, such as power surges, transients, and power failures. The following subsections describe some of these devices. Surge Protectors Surge protectors are available in a variety of types and usually provide a level of protection commensurate with the cost of the device. Surge protectors prevent voltage spikes, such as those caused during an electrical storm, from entering a system through the AC power source. Surge protectors, however, do not offer protection against brownouts, which occur when the voltage drops more than 20 percent below the normal AC line voltage level. C-136 Line Conditioners Line conditioners go beyond the overvoltage protection of surge protectors. Line conditioners keep a computer’s AC power source voltage at a fairly constant level and, therefore, can handle brownouts. Because of this added protection, line conditioners cost more than surge protectors—up to several hundred dollars. However, these devices cannot protect against a complete loss of power. Uninterruptible Power Supply An uninterruptible power supply (UPS) offers the most complete protection against variations in power because it uses battery power to keep the system running when AC power is lost. The battery is charged by the AC power while it is available, so once AC power is lost, the battery can provide power to the system for a limited amount of time—from 15 minutes to an hour or so— depending on the UPS system. UPS systems range in price from a few dollars to several thousand dollars, with the more expensive units allowing you to run larger systems for a longer period of time when AC power is lost. UPS systems that provide only 5 minutes of battery power let you conduct an orderly shutdown of the system, but are not intended to provide continued operation. Surge protectors should be used with all UPS systems, and the UPS system should be Underwriters Laboratory (UL) safety approved.

A VGA feature connector can also be called a VGA passthrough connector. video adapter The logical circuitry that provides—in combination with the monitor or display—your computer’s video capabilities. A video adapter may support more or fewer features than a specific monitor offers. Typically, a video adapter comes with video drivers for displaying popular application programs and operating environments in a variety of video modes. On most current Dell computers, a video adapter is integrated into the system board. Also available are many video adapter cards that plug into an expansion-card connector. Video adapters can include memory separate from RAM on the system board. The amount of video memory, along with the adapter’s video drivers, may affect the number of colors that can be simultaneously displayed. Video adapters can also include their own coprocessor chip for faster graphics rendering. video driver Graphics-mode application programs and operating environments, such as Windows, often require video drivers in order to display at a chosen resolution with the desired number of colors. A program may include some “generic” video drivers. Any additional video drivers may need to match the video adapter; you can find these drivers on a separate diskette with your computer or video adapter. video memory Most VGA and SVGA video adapters include VRAM or DRAM memory chips in addition to your computer’s RAM. The amount of video memory installed primarily influences the number of colors that a program can display (with the appropriate video drivers and monitor capability). video mode Video adapters normally support multiple text and graphics display modes.

Each 1-MB section is called a virtual machine. virtual memory A method for increasing addressable RAM by using the hard-disk drive. (MS-DOS does not support true virtual memory, which must be implemented at the operating system level.) For example, in a computer with 8 MB of RAM and 16 MB of virtual memory set up on the hard-disk drive, the operating system would manage the system as though it had 24 MB of physical RAM. virus A self-starting program designed to inconvenience you. Virus programs have been known to corrupt the files stored Glossary 163 on a hard-disk drive or to replicate themselves until a system or network runs out of memory. The most common way that virus programs move from one system to another is via “infected” diskettes, from which they copy themselves to the hard-disk drive. To guard against virus programs, you should do the following: • Periodically run a virus-checking utility on your computer’s hard-disk drive • Always run a virus-checking utility on any diskettes (including commercially sold software) before using them VL-Bus™ An abbreviation for VESA local bus.
