The 82596 does also support 100/10, is this correct?
If so, I think I still have some Phobos EISA card for HP 9000s I
could try.

You misunderstood me - systems with a CPU newer than PA-8200 have a
very different I/O-subsystem than the older ones.

The C200 e.g. still uses a lot of LASI functionality, together with
Dino and Wax and is based in large parts on GSC-devices (although to
a lesser extend than the 32-bit 700s).

The B2000 in turn is based on the Astro system controller together
with Elroy PCI bridges and has zero GSC-devices left.
