If the MOTHERBOARD fails to boot due to improper BIOS setting, 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. Do one of the following:

Enter the correct CMOS setting

Load Optimal Defaults

Load Failsafe Defaults.

After done one of the above, save changes and exit the CMOS Setup menu.
