on the printed circuit board. See
the motherboard layout pages for
jumper locations.

CMOS Clear
JBT1 is used to clear CMOS. Instead of pins, this jumper consists of con-
tact pads to prevent accidentally clearing the contents 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 sys-
tem, remove the AC power cord and then short JBT1 to clear CMOS.
Do
not use the PW_ON connector to clear CMOS.
SCSI Termination Enable/
Disable
The SCSI Termination jumpers
allow you to enable or disable
termination for the two SCSI
channels. The normal (default)
position is open to enable SCSI
termination. See the table on the
right for jumper settings.
