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.
