I have a machine with National Semiconductor DP83815 (MacPhyter) ethernet adapter. The network is 10Base-2.

On this site they say it works. I tried it with debian live (kernel 2.6.24). It recognizes the adapter, and lets me configure it like everything is all right.

After I do all that I get no ping.

On the same machines under Windows it works flawlessly.
