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 connec-
tion. 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.
VGA Enable/Disable
JPG1 enables or disables the VGA Con-
nector on the motherboard. See the table
on the right for jumper settings. The de-
fault setting is enabled.
