Until mentioned board contains BIOS, which follows all specifications,
you may use FD without any modification. On the other side, if under "hook
and HD" you mean "hook on the fly", then you can't - neither standard
BIOSes, nor any DOS support hot swapping, for this you should write your own
device driver, but this aplied for any DOS.

FD should run on this your "minimal hardware" without trimming.
