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: 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
JWD controls the Watch Dog function. Watch
Dog is a system monitor that can reboot the
system when a software application is “hung
up”. Pins 1-2 will cause WD to reset the sys-
tem if an application is hung up. Pins 2-3 will
generate a non-maskable interrupt signal for
the application that is hung up. See the table
on the right for jumper settings. Watch Dog
must also be enabled in BIOS.
Note: When enabled, the user needs to write
their own application software in order to dis-
able the Watch Dog Timer.
