Jumpers
The mainboard provides jumpers for setting the mainboard’s functions. This section will explain how to change settings for your mainboard’s functions through the use of the jumpers.
Clear CMOS: CLEAR_CMOS
The onboard CMOS RAM stores system configuration data and has an onboard battery power supply. The long-life battery has a lifetime of at least
5 years. If you want to clear the system configuration data from the CMOS
RAM, use the CLEAR_CMOS (Clear CMOS jumper). You can clear the
CMOS by shorting 1-2 pin while the system is off. Then return it to the 2-3 pin position. Shorting the jumper while the system is on will damage the mainboard.
