Jumper Settings (JWD)
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.
Watch Dog Enable/Disable
JWD enables the Watch Dog func-
tion. Watch Dog is a system moni-
tor that can reboot the system
when a software application is
"hung up". Pins 1-2 will cause WD
to reset the system if an applica-
tion 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 can also be enabled via BIOS.
(*Note, when enabled, the user
needs to write his own application
software in order to disable the
Watch Dog Timer.)
