CMOS Clear
JBT1 is used to clear CMOS. Always remove the AC power cord from the system
before clearing CMOS. Instead of pins, this "jumper" consists of contact pads to pre-
vent the accidental clearing of CMOS. To clear CMOS, use a metal object such as
a small screwdriver to touch both pads at the same time to short the connection.
Note: For an ATX power supply, you must completely shut down the system, remove
the AC power cord and then clear CMOS. Do not use the PW_ON connector to
clear CMOS.
