Clear CMOS Jumper: CLR_CMOS1
There is a CMOS RAM onboard 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. If you want to clear the system configuration, set
the CLR_CMOS1 (Clear CMOS Jumper ) to clear data.

Important
You can clear CMOS by shorting 1-2 pin while the system is off. Then return to
2-3 pin position. Avoid clearing the CMOS while the system is on; it will damage
the mainboard.
