 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: CONN1 
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.  
						

							 
8 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.   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. Fan Power Connectors: CPU_FAN1/SYS_FAN1/PWR_FAN1 
The CPU_FAN1 (processor fan), SYS_FAN1 (system fan), and 
PWR_FAN1 (power 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. 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  
						

							 
9 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 interface for digital audio 
transmission.  Front USB Connectors: JUSB1/JUSB2  
The mainboard provides two USB 2.0 pin headers that are compliant with 
Intel®
 I/O Connectivity Design Guide. USB 2.0 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: COM2  
The mainboard offers one serial port connector without housing.  This 
connector is a 16550A high speed communication port that sends and 
receives 16 bytes FIFOs. You can attach a serial mouse or other serial 
device directly to it.  
						

							 
10 Front Panel Audio Connector: JAUD1 
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  audio ports. Otherwise, the Line-Out connector on the back panel will not function.   Clear CMOS Jumper: JBAT2 
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 JBAT2 (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, two 32-bit PCI bus slots and one CNR slot. 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.   CNR (Communication and Networking Riser) Slot (Optional) 
The CNR slot allows you to insert the CNR expansion card. CNR is a  
specially designed audio, or modem riser card for ATX family 
motherboards. Its main processing is done through software and controlled by the motherboard’s 
chipset. 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 C# INT D# INT A# INT B# PCI Slot 2 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.
