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
the JBAT1 (Clear CMOS 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.
