 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. Power supplies of 300watt (and up) are highly recommended for system 
stability. 
 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.  
 ATX 12V Power Connector: JPW1 
This 12V power connector is used to provide power to the CPU. 
 
 
 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.  3.3V-12VGND GND PW_OK-5V 5V_SB

GNDIDE 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.  Chassis Intrusion Switch Connector: JCASE1  
This connector is connected to 2-pin connector chassis switch. If the 
Chassis is open, the switch will be short. The system will record this status. To clear the warning, 
you must enter the BIOS setting and clear the status. Fan Power Connectors: CPU_FAN/SYS_FAN 
The CPU_FAN (processor fan) and SYS_FAN (system fan) 
support system cooling fan with +12V.  They support 
three-pin head connector. When connecting the wire to the 
connectors, always note that the red wire is the positive and should be 
connected to the +12V, the black wire is Ground and should be connected to GND. If the 
mainboard has a System Hardware Monitor chipset on-board, you must use a specially designed 
fan with speed sensor to take advantage of the CPU fan control. MSI Reminds You...  Always consult the vendors for proper CPU cooling fan.  21GNDCINTRO 
						

							 
9 Serial ATA Connectors: SATA1 & SATA2 
The mainboard provides dual high-speed Serial ATA interface ports.  The 
ports support 1st generation Serial ATA data rates of 150MB/s and are fully 
compliant with Serial ATA 1.0 specifications. Each Serial ATA connector can 
connect to 1 hard disk drive. Front Panel Connectors: JFP1 & JFP2 
The mainboard provides two front panel connectors for 
electrical connection to the front panel switches and 
LEDs. The JFP1 is compliant with Intel Front Panel I/O 
Connectivity Design Guide.  
 CD-In Connector: CD_IN1 
The connector is for CD-ROM audio connector. 
 SPDIF-Out Connector: JSP1 
This connector is used to connect SPDIF (Sony & Philips Digital Interconnect 
Format) interface for digital audio transmission. 
 Front USB Connector: JUSB1/JUSB2 
The mainboard provides two standard USB 2.0 pin headers 
JUSB1&JUSB2. USB2.0 technology increases data transfer rate 
up to a maximum throughput of 480Mbps, which is 40 times 
faster than USB 1.1, and is ideal for connecting high-speed USB 
interface peripherals such as USB HDD, digital cameras, MP3 players, printers, modems and the 
like. 
 MSI Reminds You...  Note that the pins of VCC and GND must be connected correctly or it may cause some damage.  Serial Port Connector: JCOM1 (Optional) 
The mainboard offers one 9-pin male DIN connector COM A (on the rear 
panel), and one optional serial port JCOM1. Both are 16550A high speed 
communication ports that send/receive/ 16 bytes FIFOs. You can attach a 
serial mouse or other serial device directly to them.

10 Front Panel Audio Connector: JAUDIO1 
The front panel audio connector allows you to connect to 
the front panel audio and is compliant with Intel ® Front 
Panel I/O Connectivity Design Guide.  
 MSI Reminds You...  If you do not want to connect to the front audio header, pins 5 & 6, 9 & 10  have to be jumpered in order to have signal output directed to the rear        1
2 9
10 audio ports. Otherwise, the Line-Out connector on the back panel will not function.   Clear CMOS Jumper: JBAT1 
There is a CMOS RAM on board that has a power supply 
from external battery to keep the system configuration data. 
With the CMOS RAM, the system can automatically boot OS every time it is turned on. If you 
want to clear the system configuration, use the JBAT1 (Clear CMOS Jumper) to clear data.  MSI Reminds You...  You can clear CMOS by shorting 2-3 pin while the system is off. Then return to 1-2 pin position. Avoid clearing the CMOS while the system is on; it will damage the mainboard. The mainboard provides one AGP slot, three 32-bit PCI bus slots. 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 slot supports 8x/4x AGP 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,  
						

							 
11  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.   PCI Interrupt Request Routing 
The IRQ, acronym 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: 
 
 Order 1 Order 2 Order 3 Order 4 PCI Slot 1 INT B# INT C# INT D# INT A# PCI Slot 2 INT C# INT D# INT A# INT B# PCI Slot 3 INT D# INT A# INT B# INT C#   
						

							 
12 BIOS Setup 
Power on the computer and the system will start POST (Power On Self Test) process. When the 
message below appears on the screen, press  key to enter Setup. 
DEL: Setup   
If the message disappears before you respond and you still wish to enter Setup, restart the 
system by turning it OFF and On or pressing the RESET button. You may also restart the system 
by simultaneously pressing , , and  keys.

14 Frequency/Voltage Control The items in this submenu includes some important settings of CPU, AGP, DRAM and 
overclocking functions. MSI Reminds You... Change these settings only if you are familiar with the chipset.  
Current FSB Frequency 
It shows the current clock frequency of the front side bus. (read only) 
Adjust CPU Ratio 
This setting controls the multiplier that is used to determine the internal clock speed of the 
processor relative to the external or motherboard clock speed. 
Adjust CPU/AGP/PCI Frequency 
This setting allows you to select the clock frequency of CPU/AGP/PCI. 
Memory Voltage 
Adjusting the DDR voltage can increase the DDR speed.  Any changes made to this setting 
may cause a stability issue, so changing the DDR voltage for long-term purpose is NOT 
recommended.  
AGP Voltage 
AGP voltage is adjustable in the field, allowing you to increase the performance of your AGP 
display card when overclocking, but the stability may be affected.  
Auto Disable DIMM/PCI Clock 
This item is used to auto detect the DIMM/PCI slots.  When set to [Enabled], the system will 
remove (turn off) clocks from empty DIMM/PCI slots to minimize the electromagnetic interference 
(EMI).   
  
						

							 
15  Spread Spectrum 
When the motherboard’s clock generator pulses, the extreme values (spikes) of the pulses 
create 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, select one of the options for EMI reduction.  
Remember to disable Spread Spectrum if you are overclocking because even a slight jitter can 
introduce a temporary boost in clockspeed which may just cause your overclocked processor to 
lock up.   
						

							 
16 Load Optimized Defaults 
You can load the optimized values provided by the mainboard manufacturer for the stable 
performance.
