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 automatically 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.
