Unless my memory fails me, booting procedure depended on TOS. It is 
TOS that reads and loads the very first sector in memory and the
boot sector uses TOS again to read the rest of the code from the
floppy. If there was  a way of distinquishing SS or DS, what use
would it be? The boot disk can be double sided or single sided depending
on how you actually compile the source code. Making use of TOS until
the control is passed to Minix OS makes life a lot easier. I just
cannot understand the question. I am sorry. Incidentally, my boot disk
is double sided.
