I have many machines with WD8003 eithernet cards in them.  The machines
range from 386-33's to 486-33 EISA systems and have no problem with the
8003.  I would look elsewhere for your problem since I can guarantee you
that this card works fine in over 60 machines that I have put them into.
Most were under ISC.

I found that it seems that the ISC TCP/IP gets lost from time to time and
can no longer find the hosts even if it is talking to one.  I run 1 slip
and 2 eithernet gates in one machine and when using broadcast and netmask
statements in netd.cf instead of what the auto script generates things seem
to work better.  When running a gated systems don't use /etc/gated it flat
has problems, set it up using multiple routed statements to the multiple
sides of the gate.  Even under very heavy load from unix-unix and unix-pci
the network hasn't gone away for a period of months.  I know this is just a
backward way around things, but until ISC can fix gated and other things it
is the best that we can do.
