JP3: 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 mainboard from operating. To clear the CMOS memory, discon-
nect all the power cables from the mainboard and then move the jumper cap
into the CLEAR setting for a few seconds.
