I'd hold on with that for a moment... I was able to gather 14 different
ISA NICs for testing with FreeBSD alpha. However, I was only able to get
the kernel to recognize 3 of them, all of which were different models
of 3com EtherLink III.
With small modifications to files, files.i386, options and options.i386 I
was able to compile these drivers into the kernel: cs, ep, ex, fe, le, sn.
These would not compile: ed, lnc, sbni.
Now I admit that due to time constraints, all I did was put a card in,
boot the system and see if the card was recognized by kernel. If not, I
moved on.
Now I said the Elinks would be recognized, however they didn't exactly
work:

Next I will see if I can repeat the panic I got with bridging.
Any questions?-)
