CMOS Clear
JBT1 is used to clear CMOS (which will also clear any passwords). Instead of
pins, this jumper consists of contact pads to prevent accidentally clearing the
contents of CMOS.
To clear CMOS, first power down the system, then
1) Unplug the power cord(s)
2) With the power disconnected, short the CMOS pads with a metal object such
as a small screwdriver
3) Remove the screwdriver (or shorting device)
4) Reconnect the power cord(s) and power on the system.
Note: Do not use the PW_ON connector to clear CMOS.
