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.

file to the flash memory:
1)
2)
3)
4)
5)
6)
7)
8)
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.
Select the Upgrade Flash from Image File menu option. You are prompted to select the
BIOS image file to program into flash memory.
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.
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”.
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.
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.
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.
Select the Quit menu option to exit UPGRADE.EXE.
X
L
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.

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)
2)
Install any optional hardware, for example disk drives, EISA expansion boards, and so on. to Chapter
3, “Service Procedures”.
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
20
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

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.

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
speeddependent 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.
Secondary Cache
This option lets you enable or disable the server’s external (secondary) cache. Enabling the secondary
cache significantly improves server performance by reducing the average number of wait states seen by the
microprocessor.
However, in some instances, disabling the secondary 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.
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.

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

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.

Computer Memory Configurations
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:

Upgrading Secondary Cache Memory
The Pentium CPU module comes with standard or burst secondary cache memory in the form of a single
in-line cache module. Secondary cache memory is designed to greatly improve the performance of the
installed CPU(s). Note that “standard” cache refers to asynchronous cache and “burst” cache to
synchronous (higher performance) cache.
You can upgrade the secondary cache memory by installing higher performance secondary cache memory
upgrades.
To install additional secondary cache memory:
1)
2)
3)
4)
5)
6)
7)
Remove the CPU module.
Place the CPU module on an anti-static surface.
Locate the secondary cache memory socket on the CPU module and remove the currently installed
cache memory module.
Remove the new cache memory module from its anti-static packaging, handling it only by the edges.
Install the cache memory module into the socket (Figure 3 - 27).
Make sure it is firmly seated into the socket.
Install and secure the CPU module to the main logic board.

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 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)
2)
3)
4)
5)
6)
7)
8)
Connect the 68-pin or 50-pin cable connector to the corresponding connector on the main logic
board.
Decide which SCSI knockout is needed. The top SCSI knockout is for a narrow 50-pin connector.
The bottom SCSI knockout is for a wide 68-pin connector (see Figure 3 - 31).
Using a screwdriver, gently pry away one of the external SCSI knockouts located at the rear of the
server.
Screw the external SCSI connector to the rear panel with the screws provided.
Connect the external device making sure the SCSI bus is properly terminated.
When using a wide external SCSI connector, set the wide SCSI jumper (J22) on the main logic board
to Enabled.
Run the SCU and any other SCSI utilities to configure the server.

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.

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.

Service Notes
Service Notes
This appendix contains the current Service Notes for the PRIORIS XL product line.
Known Server limitations.
♦
♦
♦
♦
Do not install a 5¼-inch diskette drive in the top drive bay. EMI shielding might cause elecrical
shorts to the etch on the diskette drive’s circuit board.
Due to the length of the IDE cable, make sure IDE drives are installed in drive bay slots 1 and 2.
Otherwise, the IDE cable will not reach the IDE drive’s connector.
PCI IDE expansion boards will not work in the server.
The time required to boot the server might increase when a DE422 network card is installed in a
server that uses a Pentium CPU module.
Recommended Tools
The following tools will be needed for servicing Digital PC systems. Note that test equipment must be in
calibration.
♦
Multimeter (4 1/2 digit)
♦
A philips screwdriver
♦
An antistatic wrist strap
Other Needed Materials
Cleaning agent should be an all purpose cleaner that is used in-house.
Required Special Tools.
None.
