Late nights are getting to me.  I was confusing some old NE1000 cards
I once tried.  These don't use shared RAM.  After some mucking about,
the problem appears to be confined to one machine - and OLD Cheetah 486
- and the problem is a recurrance of an old one.  With OS/2 2.0, I had
a devil of a time getting this thing to boot reliably.  It turned out
to be something in the initial loader program that would make
back-to-back write to the real time clock.  The writes were too close
together, so the RTC never got initialized properly and INT 8 was
screwy - like 3000 ms instead of 33....
Anyway, I still can't figure how these cards cause it since the
addresses are well removed, irqs are clean.  It's become more a case of
'mental mastrubation' than anything else, but thanks for you return.
