Fan Power Connectors: CFAN1/SFAN1/PWFAN1/PWFAN2

The CFAN1 (processor fan), SFAN1 (system fan), PWFAN1 (Power

Supply fan) and PWFAN2 (Power Supply fan) support system cooling fan with +12V. It supports three-pin head connector. When connecting the wire to the connectors, always take 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. This mainboard has a System Hardware Monitor chipset on-board, so that you must use a specially designed fan with speed sensor to take advantage of the CPU fan control.

MSI Reminds You...

1. Always consult the vendors for proper CPU cooling fan.

2. CFAN1 supports the fan control.

You can install Core Center utility that will automatically control the CPU fan speed according to the actual CPU temperature.

Front USB Connectors: JUSB1 / JUSB2

MSI Reminds You...

If the Power LED on the front panel flashes every two seconds, this signal tells you that one of the power connection has been protected; if the Power LED flashes every one second, it tells that the CUP has been protected due to overheating. To refresh the system, please disconnect the power cable from the computer, and then reconnect the power cable to the computer again in at least five senconds.

Hard Disk Connectors: IDE1 & IDE2

The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 66/100/

133 controller that provides PIO mode 0~5, Bus Master, and Ultra DMA 66/

100/133 function. You can connect up to four hard disk drives, CD-ROM,

120MB Floppy (reserved for future BIOS) and other devices.

IDE1 IDE2

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.

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.

Power Saving Switch Connector: JGS1

Attach a power saving switch to this connector. Press the switch once to have the system entered the Sleep/Suspend state. Press any key to wake up the system.

Jumper

The motherboard provides the following jumper for you to set the computer’s function. This section will explain how to change your motherboard’s function through the use of jumper.

Clear CMOS Jumper: JBAT1

There is a CMOS RAM on board that has a power supply from external battery to keep the data of system configuration. 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. Follow the instructions below to clear the 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.

Hardware Setup

Slots

The motherboard provides one AGP slot, and five 32-bit PCI bus slots.

AGP Slot

PCI 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/2x/1x 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, 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.

BIOS Setup

Chapter 3. BIOS Setup

BIOS Setup

This chapter provides information on the BIOS Setup program and allows you to configure the system for optimum use.

You may need to run the Setup program when:

”

An error message appears on the screen during the system booting up, and requests you to run SETUP.

”

You want to change the default settings for customized features.

MS-6702 ATX Mainboard

Entering 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 <DEL> key to enter Setup.

DEL:Setup F11:Boot Menu F12:Network boot TAB:Logo

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 <Ctrl>,

<Alt>, and <Delete> keys.

Selecting the First Boot Device

You are allowed to select the 1st boot device without entering the BIOS setup utility by pressing <F11>. When the same message as listed above appears on the screen, press <F11> to trigger the boot menu.

The POST messages might pass by too quickly for you to respond in time. If so, restart the system and press <F11> after around 2 or 3 seconds to activate the boot menu similar to the following.

CDROM

[Up/Dn] Select

Select First Boot Device

: 1st Floppy

: IBM-DTLA-307038

: ATAPI CD-ROM DRIVE 40X M

[RETURN] Boot [ESC] cancel

The boot menu will list all the bootable devices. Select the one you want to boot from by using arrow keys and then pressing <Enter>. The system will boot from the selected device. The selection will not make changes to the settings in the BIOS setup utility, so next time when you power on the system, it will still use the original first boot device to boot up.
