Jumpers

Clear CMOS Jumper: JBAT1

There is a CMOS RAM onboard 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, set

this 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.
