Sorry it took me so long to get back to you.
This grew out of, IMHO, an interaction between the 3C905B and a 3C900
card I had in the same machine.
When I took the 3C900 out of the box, the problem disappeared.  While
this was not a conclusive test, I put the 3C900 in another machine and
the 3C900 worked.

Once I took the 3C900 card out, the 3C905B would figure out, correctly,
what media type it was connected to.

With the 3C900 card in place even the media command would not get the
3C905B to recognize the 10base-2 connection.

I no longer use both of these cards in the same machine.
I "fixed" the problem by avoiding the problem.
Sorry I can't be more help.
Cheers...
