stanFL was refering to the ERD, which, of course, is not bootable and is not what you were looking for.
booting from the cd will start installation, also not what you were looking for.
the only boot floppy you can make for NT uses most of the files on the hard disk, and just boots you to NT. also not what you were looking for.
you need to make a DOS boot floppy using a 98/95/ME machine, and use that to flash your bios. i suggest once you make one, use something like winimage to take an image of the floppy for future use.
