function through the use of jumpers.
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. The battery has
long life time for at least 5 years. If you want to clear the system configuration
stored in the CMOS RAM, 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.
