X7SLM/X7SLM+ User's Manual
CMOS Clear
JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact pads
to prevent 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.

Watch Dog Enable/Disable
Watch Dog is a system monitor that can
reboot the system when a software appli-
cation hangs. Close pins 1~2 of the Watch
Dog jumper (JWD) to reset the system if an
application hangs. Close pins 2-3 to gener-
ate 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.
