This is the obvious solution. I spend all my time dealing with networks and forget the days when floppies and the like were used for moving stuff! I'll try it as soon as I have time. I suspect that at least the will get my wired working. The Realtek wireless may be another story. I suspect I'll be looking for another card soon. :-( Thanks for kicking my brain over to the right track! -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
