default setting for the onboard speaker.

ware Reset function, which is the same as power on/off. The system will do a
cold start after the Reset button is pushed. The Reset switch is a 2-pin
connector and should be installed on pins 22 and 23 of jumper block J8.

The EXTSMI (External System Management Interface) connector, JP16, is used
by some plug-in cards. Certain applications associated with these plug-in
cards use the interface for hardware control and queries.
