2.8 Jumper
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 2 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:
Clear CMOS Jumper: JBAT1
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.
