I am starting to wonder if maybe the card was jolted or something when I
moved the machine to my ISP. Could the card
still be responding to these kinds of diagnostics, even without being
squarely in the slot? Before I moved them, I am sure
that I had them talking with each other without problem. I will try a
different switch tommorrow, or try switching ports on the current
switch.

The MAC address is only one off between the two cards, and the rest of the
info is very similar, so I'd think that would mean
they are from the same lot....

As you might have seen in the recent thread, these are new cards that
don't follow the same rules as the old cards. As there is nothing in the
docs regarding them, we can only guess and come up with approximate fixes
like the one that you mentioned; this is not a correct solution, but it's
the only one that exists right now.

Richard Gooch, who also owns some CX cards, was expected to give some
statistics about loop counts needed for different operations. If you say
that one works with 1.5M, use this in both drivers.

This is the problem................................................^^^^^

...but this is not the same card as the first one. All CX cards that I
have seen until now don't report the MII transceiver correctly, while this
one does.
Please run 'vortex-diag -v' after ifconfig (or network start) to check for
manufacturing date and code.

This indicates that no link could be established. Are you sure that
everything is working properly: switch, cab`le ?
