CMOS Clear
JBT1 is used to clear CMOS. Instead
of pins, this "jumper" consists of contact
pads to prevent the 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.
Do not
use the PW_ON connector to clear
CMOS.
