Chapter 2 Server Utilities & Configuration
Server Utilities
Introduction
This chapter provides additional information about the server’s supplied software and support
documentation, restarting the server, identifying server model and serial numbers, providing a comfortable
working environment and obtaining help.
NOTE
You might have ordered additional options such as hard disk drives, tape back-up
systems, CD-ROMs or modems that have been factory installed in the server. The
documentation and any related diskettes for these options have also been provided.
Save this material for future reference.
The following software and support documentation is supplied with the server:
♦ ServerWORKS software kit contains ServerWORKS Quick Launch and ServerWORKS Manager.
◊ ServerWORKS Quick Launch contains a bootable CD-ROM disk and reference guide. The
Quick Launch program steps through the initial server setup and operating system installation
process.
◊ ServerWORKS Manager contains the software and documentation for installing the
ServerWORKS Manager LAN management tool.
Refer to the Installation Guide and the README files on the ServerWORKS Quick Launch
CD-ROM disk for more information.
♦ Server documentation box contains this User’s Guide, an Installation Guide, a Documentation
Overview, Warranty information, a Diagnostics manual, Options manuals and Registration Card.
Diagnostic software and support documentation came with the server. This software contains an
advanced set of diagnostic utilities that can be used to identify and correct problems that might be
encountered when installing, configuring or using the server.

Utilities & Configuration Digital PRIORIS ZX Server
16 MCS Logistics Engineering - Nijmegen
There are two ways to access the supplied diagnostic software:
1) During the operating system installation process, the diagnostic software is automatically copied to a
subdirectory on the MS-DOS partition. This enables to run the diagnostic software anytime from the
created MS-DOS partition.
2) When using the Install Software Conventional method in ServerWORKS Quick Launch, a bootable
diagnostic software diskette can be created. This enables to run the diagnostic software anytime
using the created diskette.
For additional information, read any README files that are on the created diagnostic diskette.
The following utilities are supplied with the server:
♦ Flash Utility. This utility enables to update or restore the server’s BIOS.
♦ SCSISelect Utility.This utility enables to configure and view settings of the installed Adaptec SCSI
controllers and SCSI devices.
♦ RAID Configuration Utility. This utility is available for RAID-ready servers only. This utility
enables to configure the RAID array.
♦ System Configuration Utility (SCU). This utility enables to configure the server when relocating,
adding, or removing EISA/ISA/PCI expansion boards and when changing the server’s factory-
defined BIOS Setup options.
Flash BIOS Update Procedure and Recovery BIOS
Procedure
The flash contains two BIOSs, one is the normal boot BIOS that happens every time the system is booted,
and the other is a 'recovery BIOS'. The 'recovery BIOS' has just enough brains for reloading the normal
boot BIOS from floppy back into flash. This recovery BIOS was loaded into flash at the factory and is
protected by the hardware jumper J7C1. It is protected by jumper because if the recovery block was
corrupted during a flash update, the recovery BIOS will be garbage and baseboard will require installation
of a new flash part.
The recover process very similar to standard FMUP BIOS flash update process. Since it has no video
capability, it gathers all the needed information from the AUTOEXEC.BAT file and uses the file extension
of .REC for selecting the recovery BIOS. When looking at the tables below, these are the minimum files
needed for successful recovery to a another version of BIOS 1.00.01.BG0_. Note that these files are taken
from the FMUP disk must be on a bootable floppy.

Flash Memory Update Program (PHLASH.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 the server's BIOS can be restored simply
by running the flash memory update utility. The server's BIOS can also be upgraded to future releases by
running the flash memory update utility along with any flash BIOS update diskette if necessary.
The flash memory update program and BIOS updates are available on the Digital Bulletin Board.
The BIOS Configuration Utility is stored in the 512KB Flash memory device and contains compress
configuration/overlay (CFG/OVL) files used to set the various system features. The Configuration Utility
is decompressed into a secure memory location and executed during system boot by pressing [F1] during
the Power On Self Test (POST). By clearing the NVRAM (switch S8C1-1) both the CMOS setup
configuration and NVRAM configuration are reset to factory defaults. These values assume that no hard
drive is installed, an unknown single processor module is installed, but a 3 -inch floppy as drive A: is
present. The clearing of NVRAM assumes the user will immediately execute the Configuration Utility to
fully configure the server.
The BIOS setup displays configuration information is on four pages, which are accessed by using the Page
Up and Page Down keys:
♦ The [F10] key saves the BIOS Setup configuration, exits the Setup utility and reboots the system.
♦ The [F5] function key loads known default configuration values (different then factory/NVRAM
default values) for all four BIOS Setup utility pages for use with a Pentium processor module.
♦ The [F6] function deletes any changes made while in the BIOS Setup utility and goes to the previous
values stored in CMOS before entering Setup via the [F1] key. Although the BIOS Setup utility can
fully configure the system, it is strongly recommended the System Configuration Utility (SCU) be
used to set the system configuration. The System Configuration Utility ensures that the information
located in Flash memory is synchronized with the configuration information stored in CMOS.

SCSISelect Utility
The Prioris server comes with an Adaptec controller and a SCSISelect configuration utility. This utility
enables to change host controller settings without opening the server or handling the SCSI controller board.
Use SCSISelect to:
♦ Check factory default settings for each device on the SCSI bus.
♦ Change SCSI device settings that might conflict with other SCSI devices.
♦ Perform low-level formatting on new SCSI disk drives.
To start the SCSISelect configuration utility:
1) Press Ctrl + A when the BIOS banner appears during the boot process.
2) When the SCSISelect configuration utility appears, follow the instructions on the screen to configure
the SCSI controller and run SCSI disk drive utilities.
RAID Configuration Utility
RAID-ready Prioris ZX 5000 MP servers include a Mylex RAID controller and RAID configuration utility.
If the RAID controller was factory installed, the RAID configuration utility appears when the server is
booted with the ServerWORKS Quick Launch CD-ROM disk. Use this utility to configure the RAID
array.
Refer to the Mylex User’s Manuals for more information.

Digital PRIORIS ZX Server Server Utilities & Configuration
MCS Logistics Engineering - Nijmegen 21
System Configuration Utility (SCU)
The SCU enables to check or change the server’s configuration. The SCU is PCI-aware, and complies with
both EISA and ISA plug and play standards. You must run the SCU each time you add, remove, or
relocate an EISA or ISA expansion board. Running the SCU is optional for plug and play and PCI
expansion boards.
Each EISA expansion board comes with a diskette that contains a configuration (.CFG) file. The .CFG file
describes the board's characteristics and the server resources that the board requires. The configuration
registers on PCI and plug and play expansion boards contain the same type of information that an EISA
.CFG file does. The server’s main logic board also comes with a .CFG file.
The SCU uses the information provided by .CFG files, configuration registers, NVRAM, and the
information that is entered, to specify a particular configuration. The SCU then configures the server by
writing the configuration information to flash memory
The SCU stores most of the configuration values in the battery-maintained memory (NVRAM) of the real-
time clock (RTC), and the rest of them in flash memory. These values take effect each time you boot the
server. POST checks the values against the actual hardware configuration; if they do not agree, it generates
an error message. You must then run the SCU to specify the correct configuration before the server boots.
Pressing F1 on the keyboard, in response to the BIOS prompt during POST, activates the BIOS Setup
The SCU modifies the CMOS RAM and EISA NVRAM, under your direction. The BIOS POST routines
and the ISA plug and play Auto Configuration Manager (ACM) actually configure the hardware.
The SCU always updates the checksums for both areas so that the BIOS can detect any potential data
corruption before the actual hardware configuration takes place. If the data is corrupted, the BIOS requests
to configure the server before it can boot.
Locating the SCU
The SCU is located on the ServerWORKS Quick Launch CD-ROM disk. The SCU can be used in one of three
ways:
1) During the Quick Launch boot process, when selecting to create a MS-DOS partition, the SCU is
copied to the MS-DOS partition on the hard disk drive. This enables to run the SCU anytime from
the MS-DOS partition.
At the MS-DOS prompt change to the SCU directory and type:
SCU.BAT
2) Using the Install Software Conventional method in ServerWORKS Quick Launch, a bootable SCU
diskette can be created. This enables to run the SCU anytime using the diskette you created.
3) The SCU can be runned by inserting the Quick Launch CD-ROM disk, rebooting the server, and
pressing the right [ALT] key during the boot process to display the SCU.
NOTE
If EISA or PCI cards have been added to the server, the SCU will be invoked
automatically when you boot from the Quick Launch CD-ROM disk. The .SCI file is
not saved when using this method to run the SCU.

Starting and Using the SCU
To start and run the SCU:
1) Turn on the server and allow the POST to complete.
2) If POST detects an error refer to Chapter 4, “Troubleshooting” and take the appropriate steps to
correct the problem. After the problem has been resolved, restart the server.
3) Start the SCU from the DOS partition or insert the SCU diskette into drive A and soft boot (reset) the
server.
From the MS-DOS Startup menu select one of the following:
1) Execute AMISCU
2) Execute AMISCU (baseboard configuration only)
3) Execute AMISCU using the Overlay Lite
4) When the SCU title appears, press any key to continue.
Afterwards, follow the instructions on the screen to access the SCU main menu.
5) From the main menu, press the up or down arrow to highlight an item and then press [Enter] to select
it. When using a mouse, point to an item and double-click the left button to select it. Press [F1] at
any time for help about a selection.
6) When needing additional information about configuring the server, select “Step 1: About
System Configuration.”
Additional Security Features
Additional Security Features are available as options in the scu and through main logic board jumpers.
The SCU includes the following setup options to improve server security:
♦ Display <F1> for Setup Message during POST - Setting this option to disabled prevents
unauthorized personnel from entering the BIOS Setup utility each time the server is turned on or
reset.
Display <F1> fot Setup Message during POST appears as an <F1> Setup prompt on the monitor
screen each time the server boots
When selecting Disable, the server does not inform when to press <F1> to enter Setup. Setup can
still be entered by pressing <F1> before POST completes.
♦ Floppy Writes - Setting this option to Disabled prevents unautorized personnel from writing data
to a diskette.
♦ Video Blanking - Settingt this option to Enabled requires a password to reactivate the monitor after
a set period of keyboard inactivity.
♦ Reset and Power Switch Locking - Setting this option to Enabled prevents the power and reset
switches from being locked out during secure mode.
The main logic boards Enable Flash Write switch (S8C1-3) should also be set to OFF to prevent
unauthorized personnel from loading a new server BIOS. Loading a new server BIOS might enable
someone to overide other server security features or introduce a virus in the server

SCU Options
The following tables list the options that are available in the SCU (Change Configuration Settings). Use
the keyboard function keys to help to select options, change values, and display help information.
NOTE
The server also has a BIOS Setup utility available to change the server’s BIOS
settings. Although the BIOS Setup utility is separate from the SCU, the SCU will
automatically update the BIOS settings. In most cases, the server will operate
according to the most recent changes regardless of which utility you use to make
changes. However, Digital recommends to use the SCU to configure the server each
time you add hardware, remove hardware, or change server settings to ensure that the
server operates properly.
The following menu fields might not reflect current BIOS or SCU revisions. Refer to
the BIOS Setup utility screens, the SCU, and any associated on-line help for more
information.
