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

in the image 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, which will damage the mainboard.

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 AGP card for 8x/4x at

1.5v (3.3v is not supported).

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.
