1. Please note that users cannot install OS, either WinME or Win98, in
their SATA hard drive. Under these two OSs, SATA can only be used
as a normal storage device.
2. To create a bootable RAID volume for a Windows 2000 environment,
Microsoft’s Windows 2000 Service Pack 4 (SP4) is required. As the
end user cannot boot without SP4, a combination installation CD
must be created before attempting to install the operating system
onto the bootable RAID volume.
To create the combination installation CD, please refer to the following website:
This chapter tells you how to install the CPU, memory modules,
and expansion cards, as well as how to setup the jumpers on the
mainboard. Also, it provides the instructions on connecting the peripheral devices, such as the mouse, keyboard, etc.
While doing the installation, be careful in holding the components and follow the installation procedures.

Hardware Setup
Central Processing Unit: CPU
The mainboard supports AMD® Athlon64 processor. The mainboard uses a CPU socket
called Socket-939 for easy CPU installation. 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 have the heat sink and cooling fan, contact your
dealer to purchase and install them before turning on the computer.
For the latest information about CPU, please visit http://www.msi.com.tw/program/
products/mainboard/mbd/pro_mbd_cpu_support.php.
MSI Reminds You...
Overheating
Overheating will seriously damage the CPU and system, always make
sure the cooling fan can work properly to protect the CPU from
overheating.
Replacing the CPU
While replacing the CPU, always turn off the ATX power supply or
unplug the power supply’s power cord from grounded outlet first to
ensure the safety of CPU.
Overclocking
This motherboard is designed to support overclocking. However, please
make sure your components are able to tolerate such abnormal setting,
while doing overclocking. Any attempt to operate beyond product specifications is not recommended. We do not guarantee the damages
or risks caused by inadequate operation or beyond product
specifications.

CPU Installation Procedures for Socket 939
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 gold arrow. The gold
arrow 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 procedures may
cause permanent damages to
your mainboard.

Installing AMD Athlon64 CPU Cooler Set
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 have the
heat sink and cooling fan, contact your dealer to purchase and install them before
turning on the computer.
1. Detach the shield of the backplate’s
paster.
2. Turn over the mainboard, and install
the backplate to the proper position.
3. Turn over the mainboard again, and
place the mainboard on the flat
surface.
Locate the two screw holes of the
mainboard.
4. Align the retention mechanism and
the backplate.
Fix the retention mechanism and the
backplate with two screws.

and then press down the other end
of the clip to fasten the cooling set
on the top of the retention mechanism.
6. Locate the Fix Lever, Saftey Hook
and the Fixed Bolt.
Lift up the intensive fixed lever.

Memory
The mainboard provides 4 slots for 184-pin DDR SDRAM DIMM (Double In-Line Memory
Module) modules and supports the memory size up to 4GB. You can install DDR266/
333/400/433/466/500/533 modules on the DDR DIMM slots (DDR 1~4).
For the updated supporting memory modules, please visit http://www.msi.com.tw/
program/products/mainboard/mbd/pro_mbd_trp_list.php.

(from bottom to top)
Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but doubles the
rate by transferring data twice per cycle. It uses 2.5 volts as opposed to 3.3 volts
used in SDR SDRAM, and requires 184-pin DIMM modules rather than 168-pin DIMM
modules used by SDR SDRAM. High memory bandwidth makes DDR an ideal solution
for high performance PC, workstations and servers.
DIMM Module Combination
Install at least one DIMM module on the slots. Each DIMM slot supports up to a maximum
size of 1GB. Users can install either single- or double-sided modules to meet their
own needs. Please note that each DIMM can work respectively for single-channel DDR, but there are some rules while using dual-channel DDR (Please
refer to the suggested DDR population table below). Users may install memory modules
of different type and density on different-channel DDR DIMMs. However, the sametype and density memory modules are necessary while using dual-channel DDR,
or instability may happen. Please refer to the following table for detailed dual-channel
DDR. Other combination not listed below will function as single-channel DDR.
1. The maximum memory speed decreases when the following two
Memory Combination is selected (you can also refer to the Recommended Memory Combination list shown in the previous page:
- Each channel is installed with two double-sided memory mod-
ules
- Both DIMM1 and DIMM3 slots are installed with double-sided
memory module.
2. Due to the South Bridge resource deployment, the system density will only be detected up to 3+GB (not full 4GB) when each
DIMM is installed with an 1GB memory module.
Installing DDR Modules
1. The DDR DIMM has only one notch on the center of module. The module will only
fit in the right orientation.
2. Insert the DIMM memory module vertically into the DIMM slot. Then push it in until
the golden finger on the memory module is deeply inserted in the socket.
3. The plastic clip at each side of the DIMM slot will automatically close.

You can barely see the golden finger if the module is properly inserted in the socket.

Power Supply
The mainboard supports ATX power supply for the power system. Before inserting
the power supply connector, always make sure that all components are installed
properly to ensure that no damage will be caused.
A TX 20-Pin Power Connector: ATX1
This connector allows you to connect to an ATX power supply. To connect to the ATX
power supply, make sure the plug of the power supply is inserted in the proper
orientation and the pins are aligned. Then push down the power supply firmly into the
connector.
ATX 12V Power Connector: JPW1
This 12V power connector is used to provide power to the CPU.
1. These two connectors connect to the ATX power supply and have to
work together to ensure stable operation of the mainboard.
2. Power supply of 300 (and up) watt is highly recommended for system
stability.

Hardware Setup
Important Notification about Power Issue
NForce chipset is very sensitive to ESD (Electrostatic Discharge), therefore this
issue mostly happens while the users intensively swap memory modules under S5
(power-off) states, and the power code is plugged while installing modules. Due to
several pins are very sensitive to ESD, so this kind of memory-replacement actions
might cause chipset system unable to boot. Please follow the following solution to
avoid this situation.
Unplug the AC power cable (shown in figure 1) or unplug the ATX1 & JPW1 power
connectors (shown in figure 2 & figure 3) before the 1st installation or during system upgrade procedure.
The mainboard provides a standard PS/2® mouse/keyboard mini DIN connector for
attaching a PS/2® mouse/keyboard. You can plug a PS/2® mouse/keyboard directly
