[I was once in a similar situation: NT on the primary master IDE disk
in the PC provided by my employer, so I put NetBSD onto a full disk as
the secondary master. Here's how I booted the machine...]
As a first pass at a solution, you might like to look into GRUB: The
Grand Unified Boot Loader. You'd have to construct your own GRUB-
bootable floppy, but that is relatively painless with NetBSD [using
'dd', though only marginally less difficult than using rawrite.exe
Put your custom boot menu on the floppy [with just two major entries:
one for NT, and one for NetBSD---the examples provided show you how to
do all of this], then, just boot the machine from floppy every time!

Pass. Next question, please.
