1.8.2 CMOS Clear (JCMOS1)
The AIMB-275 A2 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.
