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.
