Clear CMOS Jumper: JBAT1

There is a CMOS RAM onboard that has a power supply from an external battery to

keep the data of system configuration. With the CMOS RAM, the system can auto-

matically boot OS every time it is turned on. If you want to clear the system configuration,

set the jumper to clear data.

Important

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.
