I ran across something similar to this not too long ago.  I don't
recall the D5 message, but the system would just hang at
initialization time.  It turned out to be the way the motherboard wait
states were set.  Apparently the Intelliport board (unlike the
Advantage board) has a problem with certain timings on certain
motherboards.  As I recall, I added a wait state to memory refresh and
it started working.  I say memory refresh, but it could also have been
i/o waits -- sorry, I just don't remember exactly.
