Chapter 5: Advanced Motherboard Setup

Onboard Speaker Enable/ Disable

The JD1 header allows you to use either an external speaker or the in- ternal (onboard) speaker. To use the internal onboard speaker, close pins 6 and 7 with a jumper. To use an external speaker, remove the jumper and connect the speaker wires to pins 4 (+5V) and 7 (control signal). See the table on the right for settings and the table associated with the Power LED/ Keylock/Speaker connection (previ- ous section) for jumper settings.
