MS-6593 ATX Mainboard

The motherboard provides the following jumpers for you to set the

computer’s function. This section will explain how to change your

motherboard’s function through the use of jumpers.

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.

FSB Clock Jumper: SW3

This jumper provides 100MHz and 133MHz Front Side Bus frequency

selection.

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.
