Cmos Clear; Watch Dog - Supermicro X7DAL-E User 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.
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. Closing
Pins 1-2 will cause WD to reset the system if an
application hangs. Close Pins 2-3 to generate a
non-maskable interrupt signal for the application
that hangs. See the table on the right for jumper
settings. Watch Dog must also be enabled in the
BIOS.
