CMOS Clear
JBT1 is used to clear CMOS. Instead of pins, this jumper consists of con-
tact pads to prevent accidentally clearing the contents of CMOS.
To clear CMOS, 1) First unplug the power cord(s) 2) With the power discon-
nected, short the CMOS pads with a metal object such as a small screw-
driver 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.
