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 pin 2 and 3 while the system is off. Return the
jumper to pin 1 and 2 afterwards. Setting the jumper while the
system is on will damage the mainboard.
Setting 1 2 3
Normal Operation (default) ON ON OFF
Clear CMOS setting OFF ON ON
Caution:
Except when clearing the RTC RAM, never remove the CLEAR_CMOS
jumper cap from the default position. Removing the cap will cause
system boot failure. Avoid clearing the CMOS while the system is on; it
will damage the mainboard.
