CMOS Clear
JBT1 is used to clear CMOS. In-
stead of pins, this jumper consists
of contact pads to prevent acci-
dentally clearing the contents of
CMOS. To clear CMOS, use a

screwdriver to touch both pads at
the same time to short the connec-
t i o n . A l w a y s r e m o v e t h e A C
power cords from the system be-
fore clearing CMOS.
Note: For an ATX power supply,
you must completely shut down
the system, remove the AC power
cords and then short JBT1 to clear
CMOS. Do not use the PW_ON
connector to clear CMOS.
