What are the returned messages.   That might help me isolate what is
going on.    I have found in the code where the drivers are burping.

I will have to check that out.  I have always had the timeout problems
on vme hardware (sun4) but it always worked fine on sun4c hardware
(SS1 and IPX).

Yeah, that is what I am trying to load......(:+\\.....

Yes indeedy... on the olden suntoyz it is all great fun.
