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 sys-
tem when a software application hangs. Close
pins 1-2 to reset the system if an application
is hung up. Close pins 2-3 to 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
his/her own application software in order to dis-
able the Watch Dog Timer.
