Hardware Installation
Speaker On/Off Select
The system board is equipped with a buzzer which serves as the
PC's speaker. By default the buzzer is "on" allowing you to hear the
system's beep messages and warnings. If you intend to use an AC97
external speaker, turn this function off by setting JP4 pins 1 and 2 to
On.
