CMOS Clear (CMOS1)

The AIMB-581 motherboard contains a jumper that can erase CMOS data and reset

the system BIOS information. Normally this jumper should be set with pins 1-2

closed. If you want to reset the CMOS data, set CMOS1 to 2-3 closed for just a few

seconds, and then move the jumper back to 1-2 closed. This procedure will reset the

CMOS to its default setting.
