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. Do not
use the PW_ON connector to clear CMOS.

monitor that takes action when a soft-
ware application hangs.
1-2 to reset the system if a program

non-maskable interrupt for the program

implementation). Watch Dog must also
be enabled in the BIOS.
