Clear CMOS Jumper: JBAT1
There is a CMOS RAM onboard that has a power supply from an 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. If you want to clear the system configuration,
set the jumper to clear data.
Important
1. 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
