PDSM4+/PDSME+ User's Manual
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.

Watch Dog Enable/Disable
JWD allows you to enable the Watch Dog timer.
Watch Dog is used for system monitoring. It can
cause the system to reboot when a software ap-
plication hangs. Close Pins 1-2 to reset the sys-
tem if an application hangs. 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 the BIOS.
