JUMPERS

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.

WARNING: You can clear CMOS by shorting 2-3 pins while the

system is off. Then return to 1-2 pins position. Avoid clearing the

CMOS while the system is on; it will damage the mainboard.
