Watch Dog
J18 controls Watch Dog, a system
monitor that takes action when a soft-
ware application freezes the system.
Pins 1-2 will have WD reset the system
if a program freezes. Pins 2-3 will
generate a non-maskable interrupt for
the program that has frozen (requires
software implementation). Watch Dog
must also be enabled in BIOS.
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 clearing 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.
Do not
use the PW_ON connector to clear
CMOS.
