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 auto-
matically 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:

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.
