Hello!
I see.
My basic problem is that my test device, doesn't use the normal
methods of supplying a networking device. It uses PCMCIA cards to
supply them.

And when I instruct the basic PC one to add both PCMCIA things to it,
the first one goes in, that's for storage it seems, the second one,
for networking does not.

What I want to do is to produce a PC one, without the I82544 included
in it. Equivalent to a bare PC board that was created without the
embedded networking and perhaps even USB that was popular at the start
of the time period.
