If the MMGA fails to boot due to improper BIOS settings, the clear CMOS jumper clears
the CMOS data and resets the system BIOS information. To do this, use the jumper cap to
close pins 2 and 3 for a few seconds then reinstall the jumper clip back to pins 1 and 2.
If the “CMOS Settings Wrong” message is displayed during the boot up process, the fault
may be corrected by pressing the F1 to enter the CMOS Setup menu. Do one of the
following:
 Enter the correct CMOS setting
 Load Optimal Defaults
