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 clear-

ing CMOS.

Important: For an ATX power sup-

ply, you must completely shut down

the system, remove the AC power

cord and then short JBT1 to clear

CMOS.
