Introduction
iThis system board is available in different configuration levels. Depending on the
hardware configuration of your device, it may be that you cannot find several options in
your version of the system board, even though they are described.
You may find further information e. g. in the complete Technical Manual for the system board and in
the description "BIOS Setup". For detailed information see chapter "Documentation".
Further information to drivers is provided on the supplied drivers diskettes or on the "Drivers &
Utility" or "ServerStart" CD. For detailed information please look at chapter "Installing drivers". The
latest BIOS version or drivers can be found on the internet under
http://www.siemens.de/computer/service.

!Computer system boards and components contain very delicate IC chips. To protect them
against damage caused from electric static, you have to follow some precautions:
• Unplug your computer when you work inside.
• Hold components by the edge, don't touch their leads.
• Use a grounded wrist strap.
Place the system board and the components on a grounded antistatic pad whenever you
work outside the computer.
Once you have installed the system board, you should remove the battery protection (i.e.
the thin plastic plate between battery and contact spring).

Configuration
Clock frequency
!The switches may only be set as specified in the tables below for the particular processor
used.
There are also processors, which automatically always operate at the proper frequency,
regardless of the switch position.
As these new processors do not differ externally from the previous processors, we
recommend always setting the switches in accordance with the processor.
This system board you may use with Pentium II processors with 100 MHz Front Side Bus
or with Pentium III processors with 100 MHz Front Side Bus or with Celeron processors
with 66 MHz Front Side Bus.
Information on which processors can be used is available from your sales office or the
customer service center.

Main memory
Support: The system needs at least one module and can manage at most three SDRAM
modules.
PC100 modules must have an SPD-EEPROM*.
It is not possible to mix SDRAM and EDO modules.
Size: From 16 Mbytes up to 512 Mbytes SDRAM
Technology: 100 MHz unbuffered DIMM modules.
168 pin, 3.3V, 100 MHz SDRAM
2M, 4M, 8M, 16M and 32M x 64 bit
Granularity: For one socket 16, 32, 64, 128 or 256 Mbyte
* The EEPROM of PC100 modules contains a number of critical timing parameters and data
regarding the chip and the module vendor. Due to this the system board will properly recognize
the module by reading all important timing parameters specified in the EEPROM via the Serial
Presence Detect interface.

Troubleshooting
Message BIOS update
The System BIOS provides optimum support for the processor you have chosen. If the message
BIOS update for installed CPU failed
appears the microcode required for the processor inserted must still be loaded. Further information
on this is available in the "BIOS Setup" manual on the "Drivers & Utilities" CD provided.
iIf this error message occur, refer for further information to the description "BIOS Setup"
which is delivered on the "Drivers & Utilities" CD.
The screen stays blank
If your screen stays blank this may have the following cause:
The wrong RAM memory module has been inserted

See the chapter "Main Memory" for information which memory modules can be used.
ACPI S4 (Save-to-Disk) doesn't work
This system board is fully compliant for ACPI S4. Therefore it is PC98 certified by Microsoft.
If you have any problems with ACPI please ensure that all of your components are supporting
ACPI S4.
