This doesn't work, since ntldr isn't a supported binary type. GRUB
refuses to load it this way.

Upps! An option I overlooked. I've tried it, but with no success.
Forcing ntldr to load just prints four characters on screen, but
doesn't start ntldr as expected. There are two possibilities: ntldr
has to reside a a certain place in memory, or there is a
displacement the correct start adress is loacated at ...

Partly: I can force it now to load, but this does not make it run :-(

I am interested, since I have to set up a test machine equiped with
various versions of Windows 98, Windows 2000, Windows XP, Windows
2000 Server, Windows 2003, Linux in some flawers and last FreeBSD.

Linux isn't a problem, as isn't FreeBSD. But Windows ntldr just
doesn't allow for more than 10 selectable items while booting and
there are 27 Windows versions (German, English, Chinese), with
different Service packs applied to boot.
