Watch Dog

JWD controls Watch Dog, a system

monitor that takes action when a

software application freezes the

system. Pins 1-2 will have WD re-

set the system if a program

freezes. Pins 2-3 will generate a

non-maskable interrupt for the pro-

gram that has frozen (requires soft-

ware implementation). Watch Dog

must also be enabled in BIOS.

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: 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.
