Sorry to reply to my own post, but I just booted up Windows and see that
the wired interface is an Intel 82579LM and the wireless is listed as a
"1x1 11b/g/n Wireless LAN PCI Express Half Mini Card Adapter.
I am sorry I neglected looking at this before sending my last
message. I'll be surprised if the Intel wired Ethernet is not supported
by some driver in 8.0.
