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)

NOTE

Before attempting to upgrade the flash BIOS, ensure that J41 is set correctly. To

perform a flash BIOS upgrade, J41 must be set to enable. After the upgrade, make

sure J41 is set back to disable as a security measure.

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.

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." Ιf 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.

Configuring The Server

This chapter provides detailed information on how to configure the server using the System Configuration
Utility (SCU). Digital recommends that you use the SCU to initially configure the server and each time
you add hardware, remove hardware, or change server settings.
If the server was delivered with factory-installed hardware and software, the server has already been
configured.

Before Using the SCU

When familiar with utility programs and their uses, refer to the appropriate sections in this chapter to setup
or update the server’s configuration. Otherwise, carefully read and understand this chapter before
attempting to modify the server’s configuration settings.
Read any README files contained on the System Configuration Utility diskette for additional information.

In addition, have the following items readily available:

♦ A 1.44 MB formatted diskette.
♦ Configuration (CFG) files supplied with any installed EISA/PCI expansion boards.
Refer to the next section, “SCI Files and CFG Files”, for more information about CFG files.
♦ Kit installation instructions for any installed optional hardware.

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.

Running the SCU or any of its utilities from a hard disk drive might cause memory

conflicts between the SCU and application software. This specifically applies to

memory managers and Windows applications.

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:

Boot From Diskette A

Boot From Hard Disk C
