[9fans] problems with AlphaPC164 and 21143 cards?

[Mike Haertel]

I am trying to get Plan 9 to run on my AlphaPC.  It *almost* works;
it hangs after I hit return at the "root is from..." prompt.  Here
is a transcript of the session:

I suspect the problem is with the ethernet card.  I don't see
any network activity after I hit return.  Note also that the
system claimed it is "0Mbps" rather than giving the actual
media type.

The card is an honest-to-goodness DEC DE-500, with a 21143 NIC.
(I couldn't get the SRM console to do BOOTP on a non-DEC 21140
card, so it appears I am stuck with the 21143.)

Suggestions?
