Easy. Just burn the I386 cabs onto a CD, and then use something like EZCD Creator to make it bootable with a DOS floppy. I have 2 utility CD\'s I made that do just that. They contain unattended installs for 98SE, NT4 SP6, 2K Pro SP2, and Windows XP Pro (not to mention many more utilities that I use frequently).
Simply run WINNT.EXE from within DOS, and you\'re all set. Make your own ANSWER file, and you can walk away ( winnt.exe /u:d:answerfile.txt) while it installs.
Its nice that MS still allows you to begin these installs from within DOS.
