CLR_CMOS: Clear CMOS Jumper

Use this jumper to clear the contents of the CMOS memory. You may need to clear

the CMOS memory if the settings in the Setup Utility are incorrect and prevent

your motherboard from operating. To clear the CMOS memory, disconnect all the

power cables from the motherboard and then move the jumper cap into the CLEAR

setting for a few seconds.

Note: To avoid the system unstability after clearing CMOS, we recommend users

to enter the main BIOS setting page to “Load Optimal De-faults” and then

“Save Changes and Exit”.

Jumper Settings
