This will not work, he is asking to debug at the ntldr time. First, make
sure your driver is clean, build it with the Windows 2003 DDK with PreFast
and fix all the problem. Second, make sure your driver runs clean under the
checked build, and with driver verifier. Third, make sure it passes all the
HCT tests for SCSI. If it still doesn't work you are probably going to
have to beg Microsoft for help under NDA, or acquire an Arium
http://www.arium.com/ to go further.
