3.3. Clear CMOS Jumper
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 2
and 3 while the system is off. Return the jumper to pins 1 and 2 afterwards.
Setting the jumper while the system is on will damage the mainboard. The
default setting is on pins 1 and 2.

Except when clearing the RTC RAM, never remove the cap from the CLEAR_CMOS jumper default
position. Removing the cap will cause system boot failure. Avoid clearing the CMOS while the system
is on; it will damage the mainboard.
