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: You must completely shut down the system, remove the AC power
cord and then short JBT1 to clear CMOS.

Watch Dog Enable/Disable
JWD controls the Watch Dog function. Watch
Dog is a system monitor that can reboot the sys-
tem when a software application hangs. Close
pins 1-2 to reset the system if an application
hangs. Close pins 2-3 to generate a non-mask-
able interrupt signal for the application that
hangs. See the table on the right for jumper set-
tings. Watch Dog must also be enabled in the
BIOS.
