Hardware Setup
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. It also 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.
Central Processing Unit: CPU
The mainboard supports Intel Pentium 4 Northwood & Prescott Celeron processor in the 478 pin
package. The mainboard uses a CPU socket called PGA478 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 find 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 )
Example of CPU Core Speed Derivation Procedure
If CPU Clock = 133MHz
Core/Bus ratio = 23
then CPU core speed = Host Clock x Core/Bus ratio
= 133MHz x 23

CPU Installation Procedures for Socket 478
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.
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.
Installing the CPU Fan
As processor technology pushes to faster speeds and higher performance, thermal management
becomes increasingly important. To dissipate heat, you need to attach the CPU cooling fan and
heatsink on top of the CPU. Follow the instructions below to install the Heatsink/Fan:
1. Locate the CPU and its retention mechanism on the motherboard.
2. Position the heatsink onto the retention mechanism.
3. Mount the fan on top of the heatsink. Press down the fan until its four clips get wedged in the
holes of the retention mechanism.
4. Press the two levers down to fasten the fan. Each lever can be pressed down in only ONE
direction.

6
5. Connect the fan power cable from the mounted fan to the 3-pin fan power connector on the
board.
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.
Memory
The mainboard provides two 184-pin unbuffered DDR200/DDR266 DDR SDRAM, and supports the
memory size up to 2GB. To operate properly, at least one DIMM module must be installed. (For the
updated supporting memory modules, please visit
http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_trp_list.php )
Install at least one DIMM module on the slots. Memory modules can be installed on the slots in any
order. You can install either single- or double-sided modules to meet your own needs.
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.

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 300W or above power supply is suggested.
ATX 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.

MSI Reminds You...
1. Always consult the vendors for proper CPU cooling fan.
2. CFAN1 supports the fan control. You can install the PC Alert utility that will automatically control the
CPU fan speed according to the actual CPU temperature.
IDE Connectors: IDE1 & IDE2
The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 33/66/100/133 controller that provides
PIO mode 0~4, Bus Master, and Ultra DMA 33/66/100/133 function. You can connect up to four hard
disk drives, CD-ROM, 120MB Floppy and other devices.
The first hard drive should always be connected to IDE1. IDE1 can connect a Master and a Slave drive.
You must configure second hard drive to Slave mode by setting the jumper accordingly. IDE2 can also
connect a Master and a Slave drive.
MSI Reminds You...
If you install two hard disks on cable, you must configure the second drive to Slave mode by setting its
jumper. Refer to the hard disk documentation supplied by hard disk vendors for jumper setting
instructions.
Front Panel Connectors: JFP1 & JFP2

AGP (Accelerated Graphics Port) Slot
The AGP slot allows you to insert the AGP graphics card. AGP is an interface specification designed for
the throughput demands of 3D graphics. It introduces a 66MHz, 32-bit channel for the graphics
controller to directly access main memory. The mainboard supports 4xAGP card.
PCI (Peripheral Component Interconnect) Slots
The PCI slots allow you to insert the expansion cards to meet your needs. When adding or removing
expansion cards, make sure that you unplug the power supply first. Meanwhile, read the documentation
for the expansion card to make any necessary hardware or software settings for the expansion card,
such as jumpers, switches or BIOS configuration.
CNR (Communication Network Riser) Slot
The CNR slot allows you to insert the CNR expansion cards. CNR is a specially designed network,
audio, or modem riser card for ATX family motherboards. Its main processing is done through software
and controlled by the motherboard chipset.
PCI Interrupt Request Routing
The IRQ, abbreviation of interrupt request line and pronounced I-R-Q, are hardware lines over which
devices can send interrupt signals to the microprocessor. The PCI IRQ pins are typically connected to
the PCI bus INT A# ~ INT D# pins as follows:
Order1 Order2 Order3 Order4
PCI Slot 1 INTA# INT B# INT C# INT D#
PCI Slot 2 INT B# INT C# INT D# INT A#
PCI Slot 3 INT C# INT D# INT A# INT B#

CPU Clock Ratio
End users can overclock the processor (only if the processor supports so) by specifying the CPU ratio
(clock multiplier) in this field.
Auto Detect PCI/DIMM Clk
This item is used to auto detect the PCI slots. When set to Enabled, the system will remove (turn off)
clocks from empty PCI slots to minimize the electromagnetic interference (EMI).
Spread Spectrum
When the motherboard’s clock generator pulses, the extreme values (spikes) of the pulses creates EMI
(Electromagnetic Interference). The Spread Spectrum function reduces the EMI generated by
modulating the pulses so that the spikes of the pulses are reduced to flatter curves. If you do not have
any EMI problem, leave the setting at Disabled for optimal system stability and performance. But if you
are plagued by EMI, set to Enabled for EMI reduction. Remember to disable Spread Spectrum if you

15
are overclocking because even a slight jitter can introduce a temporary boost in clock speed which may
just cause your overclocked processor to lock up.
CPU Clock
Use this item to select the appropriate clock frequency of the CPU host bus.
