Chapter 2 Server Utilities & Configuration

Server Utilities

The following sections provide detailed instructions on running the MS-DOS utilities contained on the supplied CD-ROM startup diskette and CD-ROM. Note that these utilities can be copied to the hard disk drive. Refer to the operating system documentation for information on copying files.

UPGRADE.EXE

All servers have BIOS software in a read-only, non-volatile memory (ROM) chip. This BIOS initializes hardware and boots the operating system when the server is turned on. The BIOS also provides access to other services such as keyboard and disk drives.

The server comes equipped with flash memory. This means that server's BIOS simply can be restored by running the UPGRADE.EXE utility contained on the supplied CD-ROM startup diskette. You can also upgrade the server's BIOS to future releases by running UPGRADE.EXE along with any flash BIOS update diskette if necessary.

Before Using UPGRADE.EXE

If you are unfamiliar with utility programs and their uses, carefully read and understand the following instructions before attempting to use UPGRADE.EXE.

Have the following items available:

♦

Blank formatted diskette

♦

Diskette (supplied with the server)

X

Creating a Recovery Diskette

A recovery diskette should always be prepared before attempting to upgrade the BIOS. This diskette contains a BIOS image and a program to load the image into flash memory. If a problem occurs while loading the BIOS into flash memory, a beep sounds when the server is turned on. Insert the recovery diskette into drive A or B and the original BIOS is put back in flash memory.

To create a recovery diskette:

1) Insert the CD-ROM startup diskette into drive A.

2) Boot the server.

3) Allow the POST to complete.

If POST detects a configuration error(s), refer to Chapter 4, “Troubleshooting”, for possible causes and suggested solutions.

4) Highlight Run the Flash BIOS Upgrade Utility from the main menu, and then press [Enter].

This invokes UPGRADE.EXE. The following menu items appear on the screen:

Make Recovery Diskette from Flash

Make Recovery Diskette from Image File

Upgrade Flash from Image File

Save Flash to Image File

Compare Flash to Image File

BIOS Information

Exit

For on-line help, press [F1].

5) Select the Make Recovery Diskette from Flash menu option.

The message, "Please select the diskette drive that you will use to create a Flash Recovery Diskette, or select "Cancel" to abort," appears on the screen.

6) Press the [Tab] or up and down arrow keys to highlight the diskette drive you want to use, then press

[Enter]. Drive A is the default diskette drive.

The message, "Insert a formatted diskette into drive A. The contents of this diskette will be lost! and replaced with system recovery software and the BIOS image you specified. Select "Continue" to start writing the recovery diskette, or "Cancel" to abort," appears on the screen.

7) Insert a blank (formatted) diskette in drive A, and select Continue to proceed with the creation of a recovery diskette. A message window notifies when it completes. Press any key to continue.

8) Remove the recovery diskette from drive A and store it in a safe place.

X

L

Upgrading The Server's BIOS

Perform the following steps to update the server's BIOS in the flash memory and compare the BIOS image file to the flash memory:

1) Perform steps 1 through 4 from "Creating a Recovery Diskette."

Ι f the BIOS resides on a diskette, you need to use that diskette to upgrade the BIOS.

2) Select the Upgrade Flash from Image File menu option. You are prompted to select the

BIOS image file to program into flash memory.

3) Press [Enter] to list a directory of .BIN (BIOS image) files. Select the image file you want to use.

The message, "The BIOS will now be replaced by the new BIOS image you selected. Select "Program" to start, or "Cancel" to abort. Keep in mind that programming a new BIOS into Flash memory requires a fair amount of power. If you are running on battery power you should have a full charge!" appears on the screen.

4) Press [Enter] to proceed with the programming of the new BIOS into flash memory. The message,

"DO NOT TURN OFF THE POWER", appears on the screen. The flash memory is erased, then the new BIOS is copied. Depending on the size of flash memory, the programming takes 20-40 seconds.

When the programming of the flash BIOS is complete, a message briefly appears on the screen, then the server attempts to reboot. Remove the CD-ROM startup diskette to allow the server to reboot without error. If an error occurs, the flash memory is corrupted and a beep sounds when the server is rebooted. If this occurs, insert the recovery diskette into drive A or B and the original BIOS is put back in flash memory. If the server does not reboot and the beep does not sound, turn off the server.

Set the main logic board jumper J39 to recovery mode This procedure forces a BIOS recovery process.

Refer to, “Main Logic Board Jumper Locations”.

5) Insert the CD-ROM startup diskette into drive A, invoke UPGRADE.EXE and then select the

Compare Flash to Image File menu option. The message, "Select BIOS Image

File Name to compare against flash memory", appears on the screen.

6) Press [Enter] to display a list of .BIN (BIOS image) files. Select the .BIN file you want to compare with the flash memory. A message window displays whether the flash memory contains the same

BIOS as the disk file. Press any key to continue.

7) If applicable, select the Save Flash to Image File menu option. This option reads BIOS out of flash memory and stores it on a disk file. A valid image file can be used with other upgrade commands that need an image file. The default name for the image file is DEFAULT.BIN. You can type in a different file name if you do not want to use the default name.

8) Select the Quit menu option to exit UPGRADE.EXE.

SETUP.EXE

The SETUP.EXE file allows to select and permanently store information about the server's installed hardware and software in the battery-backed memory of the CMOS RAM. This information takes effect each time the server boots and can be changed each time Setup is running.

NOTE When using Setup to make changes to the server configuration, it is recommended that you use the ROM Based Setup. Use SETUP.EXE only when you need to disable or enable the ROM Based Setup option. Also, if you use SETUP.EXE to disable the

ROM Based Setup option, be sure to keep the CD-ROM startup diskette readily available. You will need it if you want to change any server setup information.

To access SETUP.EXE:

1) Insert the CD-ROM startup diskette into drive A.

2) Boot the server.

3) Allow the POST to complete.

If POST detects a configuration error(s), refer to Chapter 4, “Troubleshooting” for possible causes and suggested solutions.

4) Highlight Modify BIOS setup from the main menu, and then press [Enter].

Page 1 of Setup appears.

5) Press the right arrow key to move the cursor to the ROM Based Setup option. Change the setting to

Enable/Disable.

6) Follow the instructions on the screen to exit SETUP.EXE (saving the changes).

7) Remove the CD-ROM startup diskette.

8) Reboot the server.

EPP3SMC.EXE

EPP3SMC.EXE can be executed as an MS-DOS command or added to the CONFIG.SYS file as a device driver. In either case, use the BIOS Setup utility or the SCU to set the parallel port to EPP Mode.

SCI Files and CFG Files

The SCU creates a System Configuration Information (SCI) file each time you configure the server. This

SCI file can be used on other PRIORIS XL Servers that are equally configured and can serve as a backup to the EISA configuration stored in NVRAM memory. The SCI file is maintained on the System

Configuration Utility diskette and has a default name SYSTEM.SCI.

Configuration (CFG) files contain main logic board, EISA, PCI, and ISA expansion board vital characteristics and the server resources they require for proper operation. When installed additional EISA,

PCI, or ISA expansion boards, make sure to copy the CFG files (and overlays, if applicable) associated with the expansion boards, to the System Configuration Utility diskette before attempting to configure the server.

Refer to the option documentation for additional information.

Using the SCU

Use the SCU when experiencing problems with the hard disk and when it is necessary to reconfigure the server. In addition, the SCU should be used to modify the configuration after you add or remove hardware, or change server settings.

If this is the first time using the SCU, it is recommended to follow the procedures in the order given.

If this is a subsequent session, refer to the appropriate sections to update the server configuration.

To run the SCU, perform the following steps:

1) Install any optional hardware, for example disk drives, EISA expansion boards, and so on. to Chapter

3, “Service Procedures”.

2) Make a backup copy of the supplied System Configuration Utility diskette. Store the original in a secure place and only use the backup copy when running the SCU. When unable to make a backup copy, use the original diskette cautiously.

NOTE It is recommended to not install the SCU or any of its utilities on a hard disk drive.

Base Memory

The main logic board reserves the first 1024 KB of address space for server use. Base memory (640 KB) is first assigned to the operating system. The remaining 384 KB is assigned to either shadow main logic board BIOS, video BIOS, or for other server use.

Base memory can be modified using the 512KB-640KB mapping field.

ROM Based Setup

This option is often used by educational facilities that have public access to their servers. Disabling this option prevents unauthorized personnel from changing any server’s configuration parameters.

Parallel Port and Serial Ports

The server logically assigns LPTx and COMx names to:

♦

Parallel ports in the address order 378h and 278h.

♦

Serial ports in the address order 3F8h, 2F8h, 3E8h, and 2E8h.

This occurs during each boot process. For example, When disabling the serial port that is assigned to 3F8h as COM1, during the next boot cycle the server reassigns the name COM1 to the next enabled serial port in the sequence.

Server Boot Management

The server comes from the factory with options Boot From Diskette A and Boot From Hard C enabled.

This means that each time you turn on or reset the server it attempts to first boot from diskette A and then from hard disk drive C.

When changing the server’s boot sequence, be aware of the following:

CPU Speed

This option determines the speed used by the server each time you turn it on or reboot it:

♦

Fast

 is the normal speed and causes the CPU to run at its rated speed.

♦

Slow



(equivalent to 8 MHz) is used to reduce the effective CPU speed to be compatible with some speed- dependent application programs.

If an application program does not run correctly at full speed, try disabling all caches or changing the CPU speed to slow. Server performance will be severely degraded while operating in slow mode.

Large Drive Addressing

This option allows to select standard for IDE hard disk drives up to 528 MB. When using IDE drives larger than 528 MB and MS-DOS or MS-Windows is the operating system, select LBA convert .

Select standard for all other operating systems.

HDD Data Transfer Method

This option lets you take advantage of new IDE hard disk drive technologies. Setting this option to Auto

Optimum allows the server’s BIOS to interrogate and automatically set up any installed IDE hard disk drive for optimum performance.

Primary Cache

This option lets you enable or disable the microprocessor's internal (primary) cache. Enabling the cache controller significantly improves server performance by reducing the average number of wait states seen by the microprocessor.

However, in some instances disabling the primary cache is desired, for example, while using timedependent software. In this instance, the server can operate but not at full potential.

Also, this field can be set to either Write-Back or Write-Through mode.

X

L

NOTE If there is no secondary cache installed, make sure this option is set to disabled.

Cache BIOS ROM

This option allows the server’s BIOS to be cached in the primary cache and secondary cache (if installed).

This increases server performance because BIOS instructions are fetched from cache instead of RAM.

Shadow Video ROM

The main logic board reserves an area of DRAM for a copy of video BIOS ROM. This DRAM (called

"shadow memory") is write-protected and has the same addresses as the video BIOS ROM locations.

When shadowing video BIOS ROM, the ROM information is copied into an appropriate area in DRAM.

This increases the server’s performance because the video BIOS instructions are in fast DRAM instead of

ROM.

Cache Video ROM

This option allows the server to cache video BIOS information. Caching the server’s video ROM provides better performance at the VGA level, however, when running certain application software, conflicts might occur.

Shadow 32K at C8000, D0000, and D8000.

These options allow the server to shadow any device BIOS located in the C8000 to DFFFF address space.

Shadowing device BIOS in these areas increases the server’s overall performance.

NOTE Refer to the device's documentation to determine if this function can be performed.

AT Bus Space

This option allows to select a memory hole in upper memory (between 1 MB and 16 MB) to be used by optional network expansion boards or optional software using frame-grab memory. Selecting an available memory hole range avoids memory address conflicts by mapping the physical memory that has been addressed to the region to the top of main memory.

Refer to the user documentation supplied with the optional network expansion board or optional software to see if a specific memory range is required for proper operation. Also make sure the operating system can support the memory hole selections prior to enabling this feature.

NOTE Banyan Vines users must select AT Bus Space E00000h, 1 MB to eliminate memory address conflicts.

512KB-640KB Mapping

This option allows the address space between 80000 (512 KB) and 9FFFF (640 KB) to be mapped to the

PCI or ISA bus. Note that when this option is enabled, the amount of conventional memory under MS-

DOS is reduced by 128 KB.

PCI Device

This option allows to configure the PCI slots on the server’s main logic board when adding PCI expansion boards.

CAUTION

The PCI Device selections for factory installed PCI expansion boards should stay at the factory default settings. Modifications can cause server failure.

Main Logic Board Jumpers

Jumper pins allow to set specific server parameters. They are set by changing the pin location of jumper blocks. A jumper block is a small plastic-encased conductor (shorting plug) that slips over the pins. To change a jumper setting, remove the jumper from its current location with the fingers. Place the jumper over the two pins designated for the desired setting. Press the jumper evenly onto the pins. Be careful not to bend the pins.

The following table lists the main logic board jumpers and factory-default settings. Figure 3 - 4 shows the locations of the main logic board jumper pins. Note that the square pin of each jumper block is pin 1.

CAUTION

Do not touch any electronic component unless you are safely grounded. Wear a grounded wrist strap or touch an exposed metal part of the server’s chassis. A static discharge from the fingers can result in permanent damage to electronic components.

Adding more memory allows the server to run larger, more complicated software and run it quicker.

The amount of memory the server supports depends on the installed type of CPU module.

♦

When the i486 PCI Series CPU module is installed, the server will support up to 128 MB using

SIMM banks 0 through 3.

♦

When the Pentium 560/566 CPU module is installed, the server will support up to 256 MB using

SIMM banks 0 through 5. The Pentium 590 CPU module will support up to 512 MB using SIMM banks 0 through 7.

CAUTION

If you plan on operating the server with 64 MB memory or more and the i486 PCI

Series CPU module have been installed, an additional 128 KB of secondary cache should be installed. Failure to do so can cause server failure.

The server comes with at least 8 MB of memory.

When adding additional memory make sure to:

♦

Install 36-bit SIMMs having an access time of 70 ns or less.

♦

Fill two sockets at a time using the same SIMM size (4 MB, 8 MB, 16 MB, or 32 MB densities), type and speed.

♦

Fill banks 0 and 1 before banks 2 and 3, banks 0 through 3 before banks 4 and 5, and banks 0 through

5 before banks 6 and 7.

SCSI Configuration Guidelines

The PRIORIS XL Server includes an onboard Adaptec AIC-7870 SCSI controller. The AIC-7870 connects directly to the PCI local bus and supports up to seven SCSI devices installed within the server enclosure. Additional SCSI devices can be added to the server by using an EISA- or PCI-based SCSI controller installed in an available expansion slot in conjunction with an external SCSI expansion box.

The onboard SCSI controller also supports either industry-standard 8-bit, narrow, 50-pin or 16-bit, wide,

68-pin SCSI devices. Separate SCSI interface connectors are provided on the main logic board to connect either type of SCSI interface cable. In most cases the server has been supplied with a standard 50-pin SCSI ribbon cable installed at the factory.

The following SCSI cables are available:

♦

68-pin wide internal SCSI ribbon cable.

♦

Wide-to-narrow cable adapter for internal wide SCSI ribbon cable.

♦

Narrow internal channel - adding a narrow external channel

♦

Narrow internal channel - adding a wide external channel

♦

Wide internal channel - adding a narrow external channel

Refer to the Extended Parts List for partnumbers

The server configuration, SCSI controller, and all SCSI devices must work together for optimum performance. Use the following guidelines to configure the server and all SCSI devices:

♦

Each SCSI device (including the SCSI host adapter) must be configured with a unique ID number.

SCSI host adapters usually default to ID 7. Use SCSI ID 0 through 6 (narrow devices) and 0 through

15 (wide devices) for the remaining SCSI devices. Hard disk drives should be configured to start with SCSI ID 0 and the lower ID numbers.

♦

Both ends of the SCSI chain must be properly terminated. The sever comes with the main logic board

SCSI terminators enabled. This properly terminates the SCSI controller (the first device in the SCSI chain). The supplied SCSI ribbon cable is equipped with an active SCSI terminator installed at the end of the cable. Use only the SCSI cable supplied with the server.

SCSI device drivers are required to operate the SCSI devices. Refer to Chapter 2, “Server Utilities

and Configuration” for creating and loading the SCSI device drivers.

♦

You can add 50-pin SCSI devices to a server equipped with a 68-pin wide SCSI ribbon cable. This cable is supplied with three 68-pin to 50-pin SCSI interface converter cables to allow adding SCSI devices such as tape drives and CD-ROM systems that are not presently offered with 68-pin SCSI interfaces.

NOTE 68-pin wide SCSI devices cannot be added to a SCSI cable connected to the main logic board’s 50-pin narrow SCSI interface connector.

♦

SCSI hard disk drives are low-level formatted at the factory. Use the appropriate operating system command to high-level format any hard disk drive.

♦

If the server boots from a disk drive other than SCSI, make sure all SCSI device drivers are installed on that disk drive. SCSI devices can be used with an IDE drive only if the IDE drive is configured as drive C.

♦

Make sure the proper SCU setup options are set for SCSI operation. Refer to, “Configuring The

Server”, for additional information.

Connecting SCSI Devices

To connect SCSI devices, perform the following:

1) Connect supplied ribbon cable to appropriate device as shown.

2) Make sure cable is connected with correct orientation. Most cables and sockets are keyed so they cannot be connected backwards. If the cable or device is not keyed, you must connect pin 1 of cable to pin 1 of device's socket.

3) Pin 1 of cable is on edge with colored stripe. Pin 1 of device's socket should be marked with an arrow at one end of socket. If necessary, refer to the device's documentation for pin 1 orientation.

Connecting an External SCSI Bus

You can use the wide (68-pin) or narrow (50-pin) SCSI connector on the main logic board to connect external SCSI devices to the server.

NOTE The External Onboard SCSI field in the BIOS Setup must be set to Enabled.

To connect an external SCSI bus, follow these instructions:

1) Connect the 68-pin or 50-pin cable connector to the corresponding connector on the main logic board.

2) Decide which SCSI knockout is needed. The top SCSI knockout is for a narrow 50-pin connector.

3) The bottom SCSI knockout is for a wide 68-pin connector (see Figure 3 - 31).

4) Using a screwdriver, gently pry away one of the external SCSI knockouts located at the rear of the server.

5) Screw the external SCSI connector to the rear panel with the screws provided.

6) Connect the external device making sure the SCSI bus is properly terminated.

7) When using a wide external SCSI connector, set the wide SCSI jumper (J22) on the main logic board to Enabled.

8) Run the SCU and any other SCSI utilities to configure the server.

Each time the POST displays a message on the screen, the computer's speaker beeps twice. If an error occurs before the monitor is initialized, specific beep codes sound to alert to a problem. The table below lists a general grouping of system messages arranged by the POST countdown number. In addition, each message is accompanied by text describing the message and in most cases, a recommended solution to the problem.

NOTE Italics indicate variable parts of a message such as memory addresses, hexadecimal values, and so on. These messages can differ at each occurrence.

Beep Codes

If the POST finds an error and cannot display a message, the server's speaker emits a series of beeps to indicate the error, for example, a failure of bit 3 in the first 64 KB of RAM is indicated by a 2-1-4 beep code (a burst of two beeps, a single beep, and a burst of four beeps).

The following tables list the beep codes when it encounters an error. The first table lists fatal errors that lock up the server. The second table lists nonfatal errors that do not lock up the server.

Fatal errors are generally the result of a failed main logic board or some other add-on component (SIMM, server battery, etc.). Nonfatal errors can occur due to an improper connection between the server's rear panel video connector and the monitor.

Chapter 5 Device Mapping

This section provides a series of tables listing mapping and address information related to computer memory and various main logic board devices (keyboard controller, interrupt controller, DMA controller, etc.).

The computer's memory and address locations are allocated at the factory to operate within a standard PC environment. However, due to the number of optional devices and/or expansion boards that are available, sometimes memory and address locations need to be changed. For example, some network expansion boards require a specific memory location. If that location is already allocated, a memory conflict results and the expansion board will not operate as expected. Note that some memory, I/O and interrupt locations can be changed using the BIOS Setup utility.

CAUTION

Before changing any memory or address location, refer to the documentation supplied with the optional device, expansion board, or software application and make sure adequate information is available.
