JP1: 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 BIOS

Setup Utility are incorrect and are preventing your mainboard

from operating. To clear the CMOS memory, disconnect all the

power cables from the mainboard and then move the jumper cap

into the Clear CMOS memory setting for a few seconds. CMOS

is cleared.

Return the jumper cap to the Normal operation setting. Recon-

nect the power cables and start the system. When the POST

starts, press the delete key to start the BIOS Setup Utility and

reload BIOS optimal settings. Refer to Chapter 3 for information

on BIOS.
