MSI Reminds You...
Replacing CPU
While replacing the CPU, always turn off the ATX power sup-
ply 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 toler-
ate such abnormal setting, while doing overclocking.  Any at-
tempt to operate beyond product specifications is not
recommended.  We do not guarantee the damages or risks
caused by inadequate operation or beyond product
specifications. AMD Athlon™/Duron™/Athlon™ XP processor requires a LARGER heatsink
and fan. You also need to add thermal grease between the CPU and heatsink
to improve heat dissipation. Then, make sure that the CPU and heatsink are
securely fastened and in good contact with each other. These are needed to
prevent damaging the processor and ensuring reliable operation.  If you want
to get more information on the proper cooling, you can visit AMD’s website
for reference.

Hardware Setup
The mainboard provides 2 slots for 184-pin DDR SDRAM DIMM
(Double In-Line Memory Module) modules and supports the memory size up
to 2GB. You can install PC2100/DDR266 or PC1600/DDR200 modules on
the DDR DIMM slots (DDR 1~2).

(DDR 1~2)
Installing DDR Modules
1.The DDR DIMM has only one notch on the center of module. The mod-
ule 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 in-
serted 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.  Be-
fore inserting the power supply connector, always make sure that all compo-
nents are installed properly to ensure that no damage will be caused.
ATX 20-Pin Power Connector: JWR1
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.

IDE1 (Primary IDE Connector)
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 (Secondary IDE Connector)
IDE2 can also connect a Master and a Slave drive.
The mainboard provides connectors to connect to FDD, IDE HDD, case,
modem, LAN, USB Ports, IR module and CPU/System/Power Supply FAN.
Floppy Disk Drive Connector: FDD1
The mainboard provides a standard floppy disk drive connector that
supports 360K, 720K, 1.2M, 1.44M and 2.88M floppy disk types.
Hard Disk 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 (reserved for future BIOS) and other devices.

Fan Power Connectors: CFAN1/SFAN1
The CFAN1 (processor fan) and SFAN1 (system fan) support system
cooling fan with +12V.
Chassis Intrusion Switch Connector: J3
This connector is connected to a 2-pin chassis switch. If the chassis is
open, the switch will be short. The system will record this status and show a
warning message on the screen. To clear the warning, you must enter the
BIOS utility and clear the record.
CD-In Connector: J10
The connector is for CD-ROM audio connector.

header, pins 5 & 6, 9 & 10 have to be jumpered in
order to have signal output directed to the rear
audio ports. Otherwise, the Line-Out connector on
the back panel will not function.
