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 connec-
tion. Always remove the AC power cord from the system before clearing CMOS.
Note 1:
For an ATX power supply, you must completely shut down the
system, remove the AC power cord, and then short JBT1 to clear CMOS.
Note 2:
Be sure to remove the onboard CMOS Battery before you short
JBT1 to clear CMOS.
Note 3:
Clearing CMOS will also clear all passwords.
