Identifying Your Computer

In most instances, the best way to identify your computer is by the model/type number. The model/type number indicates the various features of the computer, such as the type of microprocessor or whether the computer is a desktop or minitower. You can find this number on the small label on the front of your computer. An example of a model/type number is 6282-54A.

Throughout this book, however, your computer is identified by the number of drive bays offered with these models. If your computer has three drive bays, it is referred to as the 3-bay design. If your computer has four drive bays, it is referred as the

4-bay design. These following naming conventions are used only where it is appropriate. Instructions without these naming conventions apply to all computer models.

3-Bay Design

With the cover on, bay 2 in the 3-bay design is not visible. This bay is intended for a hard disk drive, which does not have accessible media such as a CD-ROM drive or diskette drive. The 3-bay design has two expansion slots for adapters, as shown in the rear view below.

Handling Static-Sensitive Devices

Have you ever walked across a carpeted floor, then touched an object and received a small electrical shock? That's static electricity, and although harmless to you, it can seriously damage computer components and options.

Important

When you add an option, do not open the static-protective package containing the option until you are instructed to do so.

When you handle options and other computer components, take these precautions to avoid static electricity damage:

Limit your movement. Movement can cause static electricity to build up around you.

Always handle components carefully. Handle adapters and memory-modules by the edges. Never touch any exposed circuitry.

Prevent others from touching components.

When you are installing a new option, touch the static-protective package containing the option to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. This reduces static electricity in the package and your body.

When possible, remove the option and install it directly in the computer without setting the option down. When this is not possible, place the static-protective package that the option came in on a smooth, level surface and place the option on it.

Do not place the option on the computer cover or other metal surface.

Installing System Memory

You can add memory to your computer to increase system performance. Your computer has two connectors for installing system-memory modules. The maximum amount of system memory your computer supports is 128 MB.

The memory modules your computer uses are 168-pin DIMMs (dual inline memory modules). The preinstalled DIMMs that come with your computer are SDRAM

(synchronous dynamic random access memory) modules. The computer comes with two connectors on the system board for adding or replacing system memory. You can add extra memory or replace existing memory with other SDRAM modules or

EDO (extended data out) DRAM modules.

When installing or replacing system memory:

Use only 3.3 volt, unbuffered, 168-pin DIMMs (SDRAM or EDO DRAM)

Only nonparity modules are supported.

Any sequence of module sizes is allowed.

A mix of SDRAM and EDO modules is supported.

Modules have a maximum height of 3.175 cm (1.25 in.). Larger modules might prevent the use of the bottom expansion slot on the riser card.

SIMMs (single inline memory modules) are not supported.



Read the instructions that come with the new system memory module.


Disconnect the cables attached to the computer and remove the computer cover (see “Disconnecting Cables and Removing the Cover” on page 5).

Locate the system memory connectors on the system board. Refer to

“Identifying Parts on the System Board” on page 7.

If an adapter impedes your access to the system memory connectors, remove it. For more information, see “Removing an Adapter” on page 32.

If you need to remove a module, go to page 12.

Installing Video Memory

The maximum amount of video memory the system board supports is 2 MB. Some models come with 2 MB of video memory already installed, and do not require a video memory upgrade.

If your computer came with 1 MB of preinstalled video memory, you can install additional video memory modules to increase system performance and display modes. A video memory module kit designed for the system board comes in increments of 1 MB. You can order this kit from IBM. For the latest information, contact an IBM representative by calling one of the phone numbers in “Available

Options and Features” on page 2.

Tip

If you are uncertain of the amount of video memory installed in your computer, perform the following procedures:

1. Turn on your computer and start the Configuration/Setup Utility program

(see “Starting the Configuration/Setup Utility Program” on page 67).

2. Select Devices and I/O Ports.

3. Select Video Setup.

4. Look under Video Memory. If the value is 1024 KB, your computer has 1

MB of video memory and can accept the upgrade. If the value reads 2048, the system board is already equipped with the maximum amount of video memory and an upgrade is not needed.

5. Exit the Configuration/Setup Utility program (see “Changing Settings and

Exiting” on page 69).

14


To install video memory:




Disconnect all cables attached to the computer and remove the computer cover (see “Disconnecting Cables and Removing the Cover” on page 5).

Locate the video memory module connectors on the system board. Refer to

Chapter 4. Working with Adapters

This chapter provides information and instructions for installing and removing adapters.

When you are installing or removing adapters, it is important to resolve any resource conflicts that might arise. For example, if you install an ISA legacy adapter, you might need to manually configure the adapter by setting a variety of switches on the adapter and by using the Configuration/Setup Utility program.

Many adapters now use Plug and Play technology which enables the computer to automatically configure the adapter, provided that the required resources are available. Refer to the instructions that come with your adapter to determine if it is

Plug and Play. For more information, see “Adapter Configuration” on page 26.

Important

The following size restrictions apply to new adapters:

– In the 3-bay design, adapters longer than 17.78 cm (7.0 in.) cannot be installed.

– In the 4-bay design, adapters longer than 17.78 mm (7.0 in.) cannot be installed in expansion slot 1. Also, adapters longer than 20.32 cm

(8.0 in.) cannot be installed in expansion slot 4.

If you have the 3-bay design, the power supply does not support 25 W adapters installed in both expansion slots.

You can install a graphics (video) adapter in your computer. If the graphics adapter is an ISA adapter, the base ROM (read-only memory) is located at

C0000H.

Each time the computer is started, it searches for a graphics adapter installed in either an ISA or PCI slot. If the computer detects a graphics adapter, the video subsystem integrated in the system board is not enabled. No jumpers on the system board need to be changed if a graphics adapter is installed.

If you want to install a non-graphics ISA adapter, ensure that the base ROM address is not located at C0000H. Otherwise, the computer will recognize this as a graphics adapter and will not enable the video subsystem.

24


Adapters and the Riser Card

Your computer uses a riser card for expansion. The riser card contains expansion slots that connect adapters to the industry standard architecture (ISA) and peripheral component interconnect (PCI) buses. The data path is 16-bits wide for the ISA-expansion slots and 32-bits wide for the PCI-expansion slots.

The riser card in the 3-bay design has two shared slots that provide access to the

ISA and PCI buses. You can only install one adapter in each shared slot; thus the

3-bay design accommodates up to two adapters plugged into the riser card. The riser card in the 4-bay design has two shared slots, along with one slot dedicated to the ISA bus and one slot dedicated to the PCI bus. The 4-bay design accommodates up to four adapters plugged into the riser card. The following illustrations show the riser cards by model.

Note:

On the 3-bay design riser card, each PCI connector shares a slot with the ISA connector directly below it. On the 4-bay design riser card, one pair of shared connectors is on a side by itself. For the other pair of shared connectors, the PCI connector shares a slot with the ISA connector directly below it.

Chapter 4. Working with Adapters

25

Adapter Configuration

Along with the documentation that comes with your adapter, use the following information to help with adapter configuration.

Plug and Play Adapters

A new method for configuring ISA adapters is now used by your computer. Plug

and Play is a configuration method that makes expanding your computer easier.

Support for Plug and Play is built into the system board of your computer.

If an adapter is Plug and Play, then there are no switches or jumpers that must be set on the adapter. A Plug and Play adapter comes with configuration specifications set in memory to provide installation information to the computer during startup. When you install or remove Plug and Play adapters, this information is interpreted by the basic input/output system (BIOS), which supports

Plug and Play technology. If the required resources are available, then the BIOS software automatically configures the adapter around the resources already in use by other devices.

Many adapters designed for ISA slots are Plug and Play devices; ISA adapters that are not Plug and Play are called legacy adapters.

Notes:

1. If a resource conflict arises after installing a Plug and Play adapter, you might need to change the default resource settings on the adapter. For more information, refer to the documentation that comes with the adapter.

2. For more information on error messages from resource conflicts, see Using Your


Important

If your model is equipped with an integrated Ethernet controller, and you do not plan to use it, disable this feature under the Ethernet Support option in the

Configuration/Setup Utility program menu. Disabling Ethernet Support frees up system resources that can be used by other devices. For more information on disabling Ethernet Setup, see Using Your Personal Computer.

26


Legacy Adapters

Adapters that are not Plug and Play compatible are known as legacy devices. If you install a legacy adapter, you must manually configure it by setting switches on the adapter and by allocating system resources using the Configuration/Setup Utility program.

In the Configuration/Setup Utility program, the ISA Legacy Resources screen shows the computer resources that are typically required by adapters:

Memory resources

I/O port resources

DMA resources

Interrupt resources

From the appropriate screens, you can select available resources for the adapter you are installing. Resources not being used by ISA legacy adapters are listed as

[Available]. You must set the resources used by the newly installed ISA legacy adapter to [Not available]; this enables the software to use these system resources for the adapter.

Just as you change system resources for installed adapters, you must also change resources when you remove an ISA legacy adapter. If you remove a legacy adapter, change the resources it formerly used to [Available]. This allows the Plug and Play software to automatically use these resources for future configurations, or you can use these resources for future manual configurations.

Notes:

1. If you are installing both legacy and Plug and Play adapters, install the legacy adapters first, and then install the Plug and Play adapters. Plug and Play adapters will configure around the resources used by legacy adapters.

2. Refer to the documentation that comes with the adapter for information on required system resources.

For information on using the Configuration/Setup Utility program when configuring ISA legacy adapters see “Configuring an ISA Legacy Adapter” on page 70 or refer to Using Your Personal Computer. For more information on error messages from resource conflicts, see Using Your Personal Computer.


27

Installing an Adapter


If the adapter you are installing is Plug and Play compatible, continue with the next step. If the adapter you are installing is not Plug and Play compatible, use the Configuration/Setup Utility program to set resource information. For more information, see “Legacy Adapters” on page 27.


Read the instructions that come with the new adapter; determine if it must be installed in an ISA or PCI slot.

Turn off the computer and all other connected devices. Disconnect all cables attached to the computer and remove the computer cover (see

“Disconnecting Cables and Removing the Cover” on page 5).

If you are installing an adapter in the 3-bay design, or if you are installing an adapter in expansion slot 1, 2, or 3 in the 4-bay design, go to “Installing an Adapter in Expansion Slot 1, 2, or 3.” If you are installing an adapter in expansion slot 4 on the 4-bay design, go to “Installing an Adapter in

Chapter 5. Working with Internal Drives

Internal drives are devices that your computer uses to read and store data. You can add drives to your computer to increase storage capacity and to enable your computer to read other types of media. Examples of the different drives available for your computer are diskette drives, hard disk drives, CD-ROM drives, and tape drives.

Internal drives are installed in bays at the front of your computer. Within this book, the bays are referred to as bay 1, bay 2, and so on. Bays are part of drive brackets that house the internal drives. The 3-bay design has two drive brackets: one houses a 5.25-inch and a 3.5-inch drive, and the other houses a 3.5-inch drive. The

4-bay design also has two drive brackets: one houses two 5.25-inch drives, and the other houses two 3.5-inch drives.

Note:

A conversion kit can be used to mount a 3.5-inch drive in a 5-25-inch bay.

For more information, see your place of purchase or IBM reseller.

Your computer comes with internal drives already installed. In the 3-bay design, a hard disk drive is preinstalled in bay 2, and a diskette drive is preinstalled in bay 3. In the 4-bay design, a diskette drive is preinstalled in bay 3, and a hard disk drive is preinstalled in bay 4.

The following illustrations show the location of the drive bays in your computer.

Recognizing Power and Signal Cables

Your computer uses cables to connect internal drives to the power supply and system board.

Power Cables:

These cables connect internal drives to the power supply. At the end of these cables are plastic connectors that attach to different drives; these connectors vary in size. Also, certain power cables attach to the riser card and system board.

Power connectors are labelled as Px. When connecting an internal drive, you must use power connector P3 for a diskette drive, or P4, P5, or P6 for another type of internal drive. Use the following table to determine the points of connection for other power cables provided with your computer.

Note:

Refer to “Identifying Parts on the System Board” on page 7 to identify the points of connection on the system board.

4 Power connectors P9 and P12 can be interchanged. Only one of these connectors comes connected to the system board.

38


Signal Cables:

These flat, wide cables connect internal drives to the system board; signal cables are sometimes called ribbon cables. There are two sizes of signal cables that come with your computer:

The wider signal cable has three connectors. Two of these connectors attach to installed drives and the third attaches to the primary EIDE connector on the system board.

Note:

If you have the 3-bay design and a 5.25-inch drive is installed, you must remove this drive to connect or disconnect cables to the primary or secondary EIDE connectors. For more information, see “Removing a

5.25-Inch Drive from the 3-Bay Design” on page 49.

The narrower signal cable differs by mechanical design:

– In the 3-bay design, this cable has two connectors: one for attaching to the diskette-drive connector on the system board, and one for attaching an internal diskette drive.

– In the 4-bay design, this cable has four connectors: one for attaching to the diskette-drive connector on the system board, two for attaching internal devices, and a fourth unique connector for attaching devices with adapter strips or other special connections.

Note:

To locate connectors on the system board, see “Identifying Parts on the

System Board” on page 7.

The following are some important points to remember when connecting power and signal cables to internal drives: 5

The diskette drive and hard disk drive (standard in most models) that are preinstalled in your computer come with power and signal cables attached.

Also, if your computer comes with a CD-ROM drive, cables are attached. If you replace any drives, it is important to remember which cables attached to which drives.

If more than one IDE device is used on a single cable, one must be designated as the primary or master device and another as the secondary or subordinate device; otherwise, some of the IDE devices might not be recognized by the system. The primary or secondary designation is determined by switch or jumper settings on each IDE device.

5 The maximum number of installed internal drives depends on the mechanical design of your computer. Refer to “Drive Specifications” on page 37 for more information.


39

Also, if a CD-ROM drive and hard disk drive are installed, ensure that these two drives are attached to the same cable, with the hard disk drive designated as the master device and the CD-ROM drive as the secondary device.

When a drive is installed, ensure that the drive connector at the end of the signal cable is always connected to the drive; also, ensure that the drive connector at the other end is connected to the system board. This reduces electronic noise emanating from the computer.

To optimize performance when installing more than two hard disk drives, be sure to attach hard disk drives with faster data transfer speeds (Mode 1 or higher) to the primary hard disk drive signal cable (hard disk drives 0 and 1).

To install more than two IDE hard disk drives, you must purchase an additional signal cable. The cable must meet the following specifications:

– Maximum length: 0.46 meters (18 inches)

– Wire size: 28 AWG

– Cable capacitive loading: 200 pF maximum

To attach an external drive, you must install an adapter in the computer.

For help in selecting drives, cables, and other options for your computer, do one of the following:

Within the United States, call 1-800-IBM-2YOU (1-800-426-2968), your place of purchase, or your IBM reseller.

Within Canada, call 1-800-565-3344 or 1-800-465-7999.

Chapter 6. Working with Security Options

This chapter describes some of the security options that are available for your computer.

To erase lost or forgotten passwords in order to set up password protection, you can move the CMOS-clear (password) jumper on the system board.

Note:

Use the Configuration/Setup Utility program to set, change, or delete passwords. For more information, see Using Your Personal Computer.

To guard against writing over diskettes, you can set the write-protect switch on the system board.

The following list is a quick reference to these procedures:

“Erasing Lost or Forgotten Passwords” on page 58

“Setting the Diskette Write-Protect Switch” on page 61

Important

Moving the CMOS-clear jumper or replacing the battery restores the default settings for your computer; thus, any configuration settings that are not part of the default settings are erased. After performing either one of these actions, you must use the Configuration/Setup Utility program to save the default settings or reconfigure and save other settings.

If your model has integrated Ethernet support, note that the settings for the primary startup sequence of your computer have been factory-changed to support network-management software. These factory settings are not the default settings of your computer. If you move the CMOS-clear jumper or replace the battery, the factory settings are erased when the default settings are restored. You must use the Configuration/Setup Utility program to reset these values. For more information on the factory settings and default settings of the startup sequence for your computer, see Using Your Personal Computer.


57

Erasing Lost or Forgotten Passwords

Note:

To set, change, or delete a password, see Using Your Personal Computer.

Your computer uses complementary metal-oxide semiconductor (CMOS) memory on the system board for storing configuration and setup information. CMOS memory maintains information about:

Date and time

Security features

Power-management devices

Storage devices

Keyboard and mouse

ISA legacy configuration information

Plug and Play configuration information

Port assignments

I/O addresses and interrupts

Other selectable features

Important

Clearing CMOS memory erases the configuration of your computer. Because you need to reconfigure the computer after clearing CMOS memory, record the configuration information of your computer before altering the CMOS jumper.

Within the security features are the settings for the power-on and administrator passwords. If you need to erase a lost or forgotten password, you must erase all of the configuration and setup information by moving the jumper designated for

CMOS memory.

To locate the CMOS-clear jumper, see “Identifying Parts on the System Board” on page 7 or see the label on the underside of the computer cover. On the cover label, the jumper is referred to as the password jumper.

58



Using the Configuration/Setup Utility program, record all configuration information.


Read the "Important" box on page 57.

Turn off the computer.

Disconnect all cables attached to the computer, and then remove the computer cover (see “Disconnecting Cables and Removing the Cover” on page 5).

1

If necessary, remove the drive-bracket assembly and riser card.

2

Locate the CMOS-clear jumper on the system board. For more information, see “Identifying Parts on the System Board” on page 7 or see the label on the underside of the computer cover which refers to the jumper as the password jumper.

3

Move the jumper from its normal position pins (1 and 2) to pins 2 and 3. It might be helpful to use needle-nose pliers to move the jumper, but be careful not to scrape any system board components or crush the jumper.

Chapter 6. Working with Security Options

59

4

Wait one minute and then move the jumper back to its normal position (pins 1 and 2). This clears CMOS memory.

What to do next

When you clear CMOS memory, you must reconfigure the computer. After reassembling the computer (go to Chapter 7, “Completing the Installation” on page 62), use the Configuration/Setup Utility program to reset the date and time, reset any passwords, and reconfigure the computer. For more information on using the Configuration/Setup Utility program, refer to

Using Your Personal Computer.

Setting the Diskette Write-Protect Switch

The diskette write-protect switch controls whether you can write information to a diskette using a diskette drive. The ability to prevent writing to a diskette is particularly useful if you are concerned about the security of information that can be obtained through a network.

Note:

This switch does not affect the ability to read information from a diskette.




Disconnect all external cables attached to the computer, and then remove the computer cover (see “Disconnecting Cables and Removing the Cover” on page 5).

1

Locate the configuration switches on the system board. For more information, refer to the label on the underside of the computer cover or see “Identifying

Parts on the System Board” on page 7.

2

For normal diskette operation or for read-only diskette operation, set switch 6 as illustrated below. It might be helpful to use the end of a small screwdriver to set the switch.

Chapter 7. Completing the Installation

After working with options, you need to install any removed parts, replace the cover, reconnect any drive cables, and reconnect external cables, including power cords and telephone lines. Also, depending on the option installed, you might need to update information in the Configuration/Setup Utility program.

The following list is a quick reference to these procedures:

“Removing a Bay Panel” on page 63

“Replacing the Cover and Connecting the Cables” on page 64

“Updating the Computer Configuration” on page 66

62


Removing a Bay Panel

You must remove a bay panel if:

You have installed a drive that has accessible media in bay 1 of the 3-bay design.

You have installed a drive that has accessible media in bay 1 or bay 2 of the

4-bay design

Your computer might have a preinstalled drive in one of these bays. If you are replacing a preinstalled drive, a bay panel might have already been removed.

To remove a bay panel, pop it loose from the front of the computer.

The following illustrations show the bay panels that might come with your computer.

6

If you have a modem or fax machine attached to the computer, reconnect the telephone line to the wall outlet and the computer. Plug the power cords into properly grounded electrical outlets.


65

Updating the Computer Configuration

Important

For more extensive information on using the Configuration/Setup Utility program, see Using Your Personal Computer.

Also, you may need to install device drivers after updating the configuration settings. For more information, see the instructions that come with the option to determine if device drivers are required and how to install them. Also, video device drivers are on the Ready-to-Configure CD.

After adding, removing, or replacing options, the configuration settings will need to be updated. This reconfiguration is performed automatically by the computer or

manually by you. When the computer automatically configures an option, it uses system programs. If the system programs do not update the settings, you can use the Configuration/Setup Utility program to reconfigure the appropriate settings.

For example, when you start your computer after adding most internal hard disk drives, the settings are automatically updated, and you use the Configuration/Setup

Utility program to save those changes. However, if a resource conflict arises after an ISA legacy adapter is installed or removed, you must manually update the computer configuration and save the information.

Notes:

1. Make a record of all customized settings before you perform any of the following steps.

2. For more information on error messages from resource conflicts, see Using Your
