Hmm.  The card on the back has a RJ45 plug _and_ a BNC connector.
I don't see any AUI connector, though.

I tried changing ewa0_mode from the SRM console and it gave me the
following options:

     twisted-pair
     twisted-pair (full duplex)
     BNC
     AUI (I don't see an AUI port on the back of the machine)
     Fast
     FastFD (full duplex)
     Auto-Detect

If I set the mode to Auto-Detect, it comes back and says the mode is not
supported and defaults to twisted-pair.  If I set the mode to Fast, the
command succeeds, but the link light on my hub remains out (both the
10baseT light and the 100baseT light).  If I boot the machine in Fast
mode, NetBSD claims that the de0 device is in "autodetect" mode and
presently set to 10baseT.

Although my friend and I purchased the machines from the same person
just a few weeks apart, it sounds like I may have received one with a
different ethernet setup.

What do I need to do the upgrade, and is the cost comparable to just
buying another supported PCI ethernet card that runs at 100baseT?

Thanks for all the helpful replies on this subject!
