Clear Cmos; Watch Dog - Supermicro X7DBT-INF User Manual

X7DBT/X7DBT-INF/X7DGT/X7DGT-INF 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 clearing
CMOS. Note: You must completely shut down the system, remove the AC power
cord and then short JBT1 to clear CMOS.
Watch Dog Enable/Disable
JWD controls the Watch Dog function. Watch
Dog is a system monitor that can reboot the sys-
tem when a software application hangs. Close
pins 1-2 to reset the system if an application
hangs. Close pins 2-3 to generate a non-mask-
able interrupt signal for the application that
hangs. See the table on the right for jumper set-
tings. Watch Dog must also be enabled in the
BIOS.
