JP1: 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 BIOS
Setup Utility are incorrect and are preventing your mainboard from
operating. To clear the CMOS memory, disconnect all the power
cables from the mainboard and then move the jumper cap into the
Clear CMOS memory setting for a few seconds. CMOS is cleared.
