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 1. 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.
Note 2. Be sure to remove the onboard CMOS Battery before you short
JBT1 to clear CMOS.
Note 3. Clearing CMOS will also clear any passwords.
Watch Dog Enable/Disable
Watch Dog (JWD1) 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.
