That's not the job of ntldr.  The way you boot a NetBSD system via
the ntldr code is to write the MBR bootstrap of the NetBSD disk to
a file on the WinNT/Win2K file system (e.g C:\netbsd.dat), then you
load that file via the ntldr menu system.  The MBR code has to set
the drive - ntldr has no idea what disk it came from.  When you
reach the PBR boot stage the drive is obviously set correctly.  I
only needed it set since, as I mentioned, I overlap the MBR & PBR
(though I originally wasn't for my SCSI system).
