CMOS Clear

JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact pads

to prevent 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 short JBT1 to clear CMOS.
