JP2: Clear CMOS Memory Jumper
This jumper can clear the CMOS memory. You may need to clear the CMOS
memory if the settings in the Setup Utility are incorrect that your mainboard
can’t operate. To clear the CMOS memory, disconnect all the power cables,
and then move the jumper cap into the CLEAR setting for a few seconds.
