Introduction
This description applies for the system board D992 with PCI bus (Peripheral Component
Interconnect).
System board D992 is available in two variants: as a monoprocessor system (D992-
Mono) and as a dual-processor system (D992-Dual). This manual applies for both
variants. Explicit reference is made to any differences.
You may find further information in the description "BIOS Setup".
Further information to drivers is provided in the readme files on hard disk or on the
supplied drivers diskettes or on the "Drivers & Utility" or "ServerStart" CD.

Boards with electrostatic sensitive devices (ESD) may be identified by labels.
When you handle boards fitted with ESDs, you must observe the following points under
all circumstances:
• You must always discharge yourself (e.g. by touching a grounded object) before
working.
• Theequipmentandtoolsyouusemustbefreeofstaticcharges.
• Pull out the power plug before inserting or pulling out boards containing ESDs.
• Always hold boards with ESDs by their edges.
• Never touch pins or conductors on boards fitted with ESDs.

Recovering System BIOS - switch 1
Switch 1 enables recovery of the old system BIOS after an attempt to update has failed.
To restore the old BIOS you need a Flash BIOS Diskette (call customer service). The
existing BIOS settings are meaningless for restoring the system BIOS (e.g. the Security
menu in the Flash Write field).
OFF The System BIOS is started with the system BIOS from the system board
(default setting).
ON The system is started from the Flash BIOS Diskette in drive A. A recovery
of the system BIOS is executed.
i
If switch 1 is set to ON, switch 3 must be set to OFF (OPEN).
Write protection for System BIOS - switch 3
Switch 3 enables and disables system BIOS updating. Before an update of the system
BIOS can be carried out, write protection for the system BIOS must also be disabled in
the BIOS Setup (in the Security menu,theFlash Write field must be set to Enabled). If you wish
to update your system BIOS, please consult our customer service.
OFF System BIOS can be overwritten (default setting).
ON System BIOS is write protected.
Write protection for floppy disk drive - switch 4
Switch 4 is used to define whether floppy disks can be written or deleted in the floppy
disk drive. To write and delete floppy disks, the write protection in BIOS setup must be
disabled (in menu Security,thefieldDiskette Write must be set to Enabled).
OFF Read, write and delete floppy disks is possible (default setting).
ON The floppy disk drive is write-protected.

Upgrading main memory
The system board incorporates four locations for installing memory modules in DIMM
format (bank 0 to bank 3). The board supports a maximum of 512 Mbytes. On 333-MHz
processors with extended cache ability only, the maximum memory capacity is 1 Gbyte.
You may use EDO DRAM memory modules of 64, 128 or 256 Mbytes.
Equipping must be performed starting with bank 0 in sequence.
EDO-DRAM = Enhanced Data Output Dynamic Random Access Memory
!You ma
y
onl
y
use buffered 3.3V memor
y
modules. Unbuffered memor
y
modules are not
p
ermitted.
EDO-DRAM memor
y
modules must have an access time of 60 ns or less.
Installing memory modules
Ê Flip the holders on each side of the relevant location outwards.
Ê Insert the memory module into the location.
Ê At the same time flip the lateral holders upwards until the memory module snaps in
place.
Removing a memory module
Ê Flip the holders to the right and left of the location outwards.
Ê Pull the memory module out of its location.
Replacing the Pentium II
System board D992 dual
The system board can be upgraded with a second Pentium II processor in slot 2. You can
replace the Pentium II processor in slot 1.
If the system board contains only one processor in slot 1, a terminating board must be
inserted in slot 2 and there is no voltage converter for processor 2 inserted.
!The second Pentium II

System board D992 mono
The system board can only be operated with a Pentium II processor in slot 2. There is a
terminating board in slot 1. Voltage converter slot 1 is empty.
