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 sys-
tem, remove the AC power cord and then short JBT1 to clear CMOS.

Watch Dog Enable/Disable
Watch Dog (JWD1) is a system monitor that
reboots the system when a software applica-
tion 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.
