I am using a "Bullet" 286 XT, and I posted some diffs that were included in
the xt_wini.c that AST recently posted as the 1.2 version for the XT
disk driver.  Some of those diffs had to do with getting the
disk driver to work with the "Bullet" and a Western Digital Style
(Basic Time) Controller. The same changes allowed my system at
home (a regular IBM PC with an ordinary Western Digital Controller)
to function properly.

The change pertinent to the "Bullet" was in fact increasing the
retry count. I had increased it to 32000 (already in the 1.2 version) and
that worked fine until I built a system with Microsoft
C version 4.0. Then I had to further increase the count to 0xfff0
but that requires the variables associated with the retry count be changed
to unsigned ints. (from signed ints or shorts) These changes did NOT get
included in the 1.2 version of xt_wini.c that AST recently posted. They are
easy to do though, just look for all occurrences of the retry count
and change the associated variable types. Then change the definition
of the maximum retry count to 0xfff0. I haven't had any troubles since
with the "Bullet" 286 XT.

Hope this is of some help for you or others with the "Bullet" 286 XT.
