4.5.2 Clear CMOS Setup (JP2)
If the motherboard fails to boot due to improper BIOS settings, use this jumper to clear the
CMOS data and reset 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 displays during the boot up process, try to correct
the fault by pressing the F1 to enter the CMOS Setup menu. Then do one of the following:
Enter the correct CMOS setting
Load Optimal Defaults
After one of the above has been done, save the changes and exit the CMOS Setup menu.
