The mainboard provides jumpers for setting some mainboard functions. This
section will explain how to change the settings of the mainboard functions
using the jumpers.
Clear CMOS: CLEAR_CMOS
The onboard CMOS RAM stores system configuration data and has an
onboard battery power supply. To reset the CMOS settings, set the jumper
on pins 1 and 2 while the system is off. Return the jumper to pins 2 and 3
afterwards. Setting the jumper while the system is on will damage the
mainboard.
