Onboard Speaker Enable/
Disable
The JD1 header allows you to use
either an external speaker or the
internal (onboard) speaker. To use
the internal (onboard) speaker, close
pins 6 and 7 with a jumper. To use an
external speaker, connect the speaker
wires to pins 4 through 7 of JD1. See
the table on the right for settings and
the table associated with the Power
LED/Speaker connection (previous
section) for pin defi nitions.

Watch Dog Enable/Disable

JWD1 controls the Watch Dog function.
Watch Dog is a system monitor that
can reboot the system when a software
application hangs. Pins 1-2 will cause
WD to reset the system if an applica-
tion has frozen. Pins 2-3 will generate
a non-maskable interrupt signal for the
application that is frozen. See the table
on the right for jumper settings. Watch
Dog must also be enabled in BIOS.
