    The only difference you will notice is that SYS and FORMAT /S will
no longer work properly if it's PC-DOS's IBMBIO and IBMDOS, and MS-DOS's
utilities (or vice versa).

    No, you'll have to edit the boot sector too - it contains the names
of the files that MUST be there for it to work.  Of course, if you can
do that, you can also just rename IBMBIO and IBMDOS; but be aware of the
not in item 1.

    You *should* be able to delete IBMBIO.COM and IBMDOS.COM and then
SYS the system (after having booted from the floppy, and using the SYS
command from the floppy, not from the hard disk.).  If SYS refuses, reboot
the system from the floppy after you delete the files, then COPY both
IO.SYS and MSDOS.SYS to the hard disk.  (You reboot to make sure that DOS
will put them in the lowest available clusters.
