Hi, I downloaded Backtrack 2.0 Final, and burned it to a CD

I bought a new wireless card, a cheapy that would do the job (TRENDnet TEW-423PI) and I wanted to see if Backtrack supported it, so I searched around and found this site someone recommended:

It has the TRENDnet TEW-401PC, just not my card

How would I setup or install the drivers for the card onto the backtrack installation?

Or any topics about this before? I couldn't find much, thanks in advance
