Clear CMOS Jumper:JBAT1

There is a CMOS RAM on board 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. That battery has
long life time for at least 5 years. If you want to clear the system configuration,
use the JBAT1 (Clear CMOS Jumper ) to clear data. Follow the instructions
below to clear the data:

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.
