[comp.os.minix] Modifying the ethernet driver

RON@psuvm.psu.edu (Ron McCarty) (03/14/91)

I tried this before and got no response. That probably means no one has an
answer but i'll try anyway.

We have MINIX running on ps2/70s which are connected to DECNET using
"DEMCA" ethernet cards. We would like to modify the MINIX driver to
communicate with these cards. However, we have been unable to get
documentation from DEC concerning control regsiter formats and
assignments. Does anyone out there
      - have technical data about DEMCA?
      - know where one could get their hands on such data?
      - have a strategy for figuring out the formats etc by studying
        the card in action?
      - have any other suggestions?

I would gladly pay for the information if I could just find out where to get
it.

Thanks ahead of time for any help.
