I see, thanks, @wessu. It makes sense since the motherboard is pretty new (by my standards, anyhow). Appreciate your help, guess I'll need to find some different h/w or get a different ethernet board as you suggested.
@rojoone2 Thanks for your help trying to get me operational. It seems that with no appropriate ethernet driver the machine is not coming onto the network.
Once I get compatible hardware hopefully I'll be back on the board with a success story!
