Thanks to the following people (in no particular order):
James C. Bevier & D. Michael McFarland. In a message exchange on the reddhat-list they provided some information on how to boot NT from Linux.
Gilles Vollant. BootPart is a very useful utility and Gilles makes it available for free with some nice documentation. Thanks Gilles.
Mike Harlan. By reading his 'Linux-DOS-Win95-OS2' mini-HOWTO, it helped me make some assumptions about LILO's behavior.
