mic bias same as mic voltage?

[raygan_gamer]

So I'm trying out this X-FI to Front Panel mod and I'm connecting my stacker 830 front panel audio wiring...I'm just lost on the MIC voltage...the rest of the wires are labeled...the only thing I see related to the MIC is this MIC BIAS...is this the voltage being referred to in the tutorial?
advance thanks
