Hi Mike,
Thanks for the response....

Don't know for sure, but these are both two well know cards:
Cardinal MPV288C2
Megahertz XJ2288

Didn't help. I got the passed the probe error on the cardinal but then
go the unfielded interrupt later.

Actually one or the other occurs depending on the reset delay:
probe 3 fails or the fielded interrupt. An then there is the
64 stray strange interrups on sio0..
Thanks for the suggestions,
Mark
