I've had a little correspondence with Larry Stefani
<stefani@lkg.dec.com> since I posted.

Not only do I no longer have access to the machine, the mail I sent at
the time was... ah... misappropriated by my clients. I corresponded with
Matt Thomas <thomas@lkg.dec.com>, who wrote the driver, and knows what
the incompatibilities are.

The machine I put together was a Gateway 2000 P-166 with 2 FDDI cards,
an NEC chipset SCSI controller, and Gateway's Matrox
Not-Quite-Millenium-MGA card in the PCI slots. Gateway's motherboard
uses the Intel Triton chipset, and this is the source of the trouble.
Once I'd added 'pseudo-device fddi', 'device dfa0' and 'device dfa1' to
the config file, I found that soon after traffic started to go over the
FDDI, the machine would lock up, with one card or two.

IIRC, the boards I had were revision C, and D or later was what I needed
- Matt and Larry, I'm sure, will be able to provide more details.

I hope this helps. Well, in fact, I hope it's irrelevant ;-)
