I agree that doesn't answer the specific question of "is this particular = RealTek chipset supported". The point I was really trying to make is = that, in my experience, RealTek NICs have performed so poorly that I = would avoid them completely thereby making the status of their support = irrelevant. Again, my anecdote was intended to direct you away from a = path that may have more pain in it than you want. Chris=
