This message was composed from a machine that was connected to the
Internet with the ex driver:

so it looks like it is working.  Not sure why it is getting those
Oerrs, but I'm not seeing anything major wrong with it.

I'd say we're a 'go' for committing this card.  I have some ISA
versions of this card, but no ISA machines to test them on.  Rather
begs the question why I still have the ISA card collection...

P.S.  I've not tried to eject the card yet....
