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
jumper is labeled as “JM1”. The default setting is on pins 1 and 2.

Except when clearing the CMOS RAM, never remove the cap from the JM1 (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.
