  I had this same problem, did lots of chasing and found the 2nd stage boot
code had a BIG broken in it ! It would work with a real W.D. chipset
controller, but NOT some of the clones. Turns out to be a real NO NO in the
code, using registers explicitly stated as WRITE ONLY, and explicitly stated
as 4 bits big, as a READ for status (trying to read the TOP 4 bits, which
are stated to BE RESERVED and UNDEFINED !!!!).
  To make the long story short, we posted a fix to the net, see article 2608.
This includes diffs and a uuencoded bootwd needed to correct the problem.

Jim
