Clear CMOS Jumper: JP5
There is a CMOS RAM onboard that has a power supply from an external battery to keep the data of
system configuration.
For normal state (default), the jumper is set on pin location 1 and 2.
To clear the CMOS, set the jumper to pin location 2 and 3 for at least 30 seconds while the system is off.
1. You can clear CMOS by shorting pin 2-3 for at least 30 seconds (while the system is
OFF), then place the jumper back to pin 1-2 for normal operation.
2. Avoid clearing the CMOS while the system is ON; this will damage the mainboard.
