Actually, with dos 4.01 this is not true.  The sys command will work on any
drive that has an old system on it.  I installed it quite a few times this
weekend on disks that had 3.3 on them, and lots of other software as well.
Worked every time.  Could there be differences in releases.  I am using IBM
dos.  Is this different than MS?
