Clear CMOS
JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact pads
to prevent 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.
Always remove the AC power cord from the system before clearing CMOS.
Note: For an ATX power supply, you must completely shut down the
system, remove the AC power cord and then close pins 1 and 2 to clear
CMOS.
