The problem of having DOS and Windows coexist. It might be OK with XP,
which certainly coexists happily with earlier versions of Windows; I
don't know if that extends to DOS but I'm sure I'd find out quite
quickly if I tried it :-) If I do I'll let the list know in case it
helps anyone else who needs an environment for retro software/hardware.

Yes, it's called a DPDT switch ;-) Or you can just use a boot floppy.

I've not seen anything and in fact last time I looked at Linux's
support for non-PC formats, notably anything that started it's sector
numbering at zero as %deity intended, it was sadly lacking (but that
was quite a while ago)

That's the main reason. I'd use teledisk for disk images, as people
seem to use that much more often.
