Jumpers
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 automati-
cally 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 main-
board.
