Watch Dog Enable/Disable
Watch Dog (JWD) is a system monitor that
reboots the system when a software appli-
cation 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.

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.
