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 ob-
ject 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.
Do not use the PW_ON
connector to clear CMOS.
