It is most likely an rj45 connector like Ethernet.  If it is an adapter
like this, it is either the AUTO adapter or the Turbo adapter.  I don't
_think_ they made any other adapters that were non-streamers that had the
RJ45 connect but I could be wrong.  Wait, yes I am.  If it doesn't have
switches on it, it is either the Auto or the Turbo adapter.  :)  If it
still has switches on it, it's probably close to the same adapter you have
in the 8bit slot and I am pretty sure I know which one you mean (and have
used it with Linux).

I do not have a hardware manual around for the token ring cards.  I need
to track one down - I don't work with token ring as much as I used to.  I
have always used the settings:

UDUUUDDDUUDU - which will configure it for a 16Mbit ring.  Not sure
anymore what the IRQ and Mem is on that either anymore.  Sorry - just have
the switch pattern engraved into my head.  If you have a 4Mb ring, I think
you need to switch the last switch to D.  (U=up D=down BTW).  See if that
helps any.  It may or may not depending on your system configuration.

If it has a 16/4 sticker, and is the card that I am thinking of, it should
go 16Mbit fine.

Yes, it is definately a problem - if you do a 'dmesg' the kernel is most
likely spitting all kinds of errors out at you every few seconds as it
tries to insert into the ring.  Get it onto the ring, make sure that the
routes are configured properly and then try a ping.
