Clear CMOS jumper: JM1
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.

the system is on; it will damage the mainboard.
