Serial Port Connector: JCOM1 (Optional)

The mainboard offers one 9-pin male DIN connector COM 1 (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.

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.
