CMOS Clear<br />
JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact pads<br />
to prevent accidental clearing of CMOS. To clear CMOS, use a metal object such<br />
as a small screwdriver to touch both pads at the same time to short the connection.<br />
Always remove the AC power cord from the system before clearing CMOS.<br />
Note 1: For an ATX power supply, you must completely shut down the<br />
system, remove the AC power cord, and then short JBT1 to clear CMOS.<br />
Note 2: Be sure to remove the onboard CMOS Battery before you short<br />
JBT1 to clear CMOS.<br />
Note 3: Clearing CMOS will also clear all passwords.<br />
Watch Dog Enable/Disable<br />
Watch Dog (JWD1) is a system monitor that<br />
can reboot the system when a software application<br />
hangs. Close pins 1-2 to reset the<br />
system if an application hangs. Close pins<br />
2-3 to generate a non-maskable interrupt<br />
signal for the application that hangs. See the<br />
table on the right for jumper settings. Watch<br />
Dog must also be enabled in the BIOS.<br />
