10. Bass/Center setting (3-pin BCS1, BCS2) (on audio models only)
These jumpers allow you to select the speaker output for a 6-channel
audio system. Switch the jumpers from the CENTER/BASS (pins 1-2)
position to BASS/CENTER (pins 2-3) position to re-route signals on the
internal leads of the Mic port.
Use the audio driver included in the support CD to install the multi-
channel audio feature.

(on audio models only)
By default, these jumpers are shorted (jumper caps on) to route the
signal from the audio controller to the rear panel Line Out jack to make
it available for audio out devices such as speakers or a headphone.
If you connect the Intel Front Panel audio cable to the FP_AUDIO
connector (see page 2-35 for the location), remove the caps from
these jumpers to allow automatic switching of audio signal between the
rear panel Line Out jack and the audio cable.
