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 clear-
ing 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.

Watch Dog Enable/Disable
Watch Dog (JWD) is a system monitor that
can reboot the system when a software ap-
plication hangs. Close Pins 1-2 to reset the
system if an application hangs. Close Pins
2-3 to generate a non-maskable interrupt
signal for the application that hangs. See the
table on the right for jumper settings. Watch
Dog must also be enabled in the BIOS.
