Clear CMOS Jumper: JBT1
Caution Always remove the AC power cord from the system before clearing CMOS.
Caution 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.
Use JBT1 to clear CMOS. Instead of pins, this “jumper” consists of contact
pads to prevent accidental CMOS clearing. To clear CMOS, use a metal
object such as a small screwdriver to touch both pads at the same time to
short the connection.

mode). For the CompactFlash card to work properly, you must connect the
CompactFlash card power cable to JWF1 and close this jumper to enable it.
The default setting is disabled.
