FCC-A Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits for a class
A digital device, pursuant to part 15 of the FCC rules. These limits are designed
to provide reasonable protection against harmful interference when the equip-
ment is operated in a commercial environment. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accor-
dance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference, in which case the user will be required to correct
the interference at his own expense.
Notice 1
The changes or modifications not expressly approved by the party respon-
sible for compliance could void the user’s authority to operate the equipment.
Notice 2
Shielded interface cables and A.C. power cord, if any, must be used in order to
comply with the emission limits.

MSI Special Features
PC Alert™ III
The PC AlertTM III is a utility you can find in the CD-ROM disk. The
utility is just like your PC doctor that can de-
tect the following PC hardware status during
real time operation:
ØmonitorCPU &system temperatures
Ømonitor fan speed(s)
Ømonitor system voltage
Ømonitor chassis intrusion
If one of the items above is abnormal,
the program main screen will be immediately
shown on the screen, with the abnormal item
highlighted in red. This will continue to be
shown until user disables the warning.
MSIRemindsYou...
1. Items shown on PC Alert™ III vary depending on your system
status.
2. The mainboard bound with mBMC chip (Server Management
Features) won’t support PC Alert™ III.

Hardware Setup
This chapter provides you with the information about hard-
ware setup procedures. While doing the installation, be careful
in holding the components and follow the installation
procedures. For some components, if you install in the wrong
orientation, the components will not work properly.
Use a grounded wrist strap before handling computer
components. Static electricity may damage the components.

Hardware Setup
The mainboard supports Single/Dual Intel®Xeon™ processor(s). The
mainboard uses two CPU sockets called Socket 604 for easy CPU installation.
You can install SINGLE or DUAL CPUs on the board to meet your own
needs. Keep the following points in mind before installing CPU(s):
1. If SINGLE CPU is intended, always install the CPU on the CPU1
socket.
2. To install DUAL CPUs on the board, you must use the same type
of CPUs running at the same FSB frequency.
Central Processing Unit: CPU
When you are installing the CPU, make sure the CPU has a Heat Sink
and a cooling fan attached on the top to prevent overheating. If you do
not find the Heat Sink and cooling fan, contact your dealer to purchase and
install them before turning on the computer.
MSI Reminds You...
Overheating will seriously damage the CPU and system, always
make sure the cooling fan can work properly to protect the CPU
from overheating.
The system temperature needs to remain under 45°C.
We highly recommend that the direction of inlet air should follow
the direction indicated above for better cooling effect.
CPU1
Recommended inlet air direction

2-4
MS-9125 SSI Mainboard
1. Please turn off the power and
unplug the power cord before
installing the CPU.
2. Pull the lever sideways away
from the socket. Make sure
to raise the lever up to a 90-
degree angle.
3. Look for the cut edge. The cut
edge should point towards the
lever pivot. The CPU can only
fit in the correct orientation.
4. If the CPU is correctly
installed, the pins should be
completely embedded into the
socket and can not be seen.
Please note that any violation
of the correct installation pro-
cedures may cause permanent
damages to your mainboard.
5. Press the CPU down firmly
into the socket and close the
lever. As the CPU is likely to
move while the lever is being
closed, always close the lever
with your fingers pressing
tightly on top of the CPU to
make sure the CPU is properly
and completely embedded
into the socket.

Hardware Setup
The mainboard provides 6 slots for 184-pin DDR SDRAM DIMM
(Double In-Line Memory Module) modules and supports up to 12GB memory
size. You can install PC2100/DDR266 or PC1600/DDR200 modules on the
DDR DIMM slots (DIMM 1~6).

Each DIMM slot supports up to a maximum size of 2GB. Users can
install either single- or double-sided modules depending on their needs, but
memory modules must be installed on the board IN PAIRS.
