This is probably too simplistic to be helpful..., but what I
do is put a modified/stripped-down bootsect.S (512 bytes) on a
floppy.  I can (theoretically) tell that code which hard drive
to boot from (like 0x80 or 0x81).  I haven't tried it with
more than 2 drives (don't have more than 2 drives).

And I install LILO on each target boot drive.  LILO complains
a little bit, but it still works.
