5.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. No audio standard exists for the three pick-up surfaces on male audio ports, so it is necessary to switch the jumpers from the default position CENTER/BASS (pins 1-2) to BASS/CENTER (pins 2-3) 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. See section Ò5.3 Software information.Ó

6.DDR voltage selector (4-pin DDRVOL1)

This jumper allows you to select the voltage supplied to the system memory by changing the jumper setting.

It is recommended that you keep the default setting (2.5V) for system stability. The other settings do not guarantee better system performance.
