Jumpers Jumpers Jumpers 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 Connector: CLEAR_CMOS1
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.

system boot failure. Avoid clearing the CMOS while the system is on;
it will damage the mainboard.
