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

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 Defaults

and then Save Changes and Exit.
