(Sorry, I inserted uneeded "and"... Should be "the 'sys' command to"...)
There is no authorized access for a DOS PC. It's entirely based on trust
of
the individual. You could copy all the available DOS files from the
machine, but they were unuseable without a bootable DOS disk. DOS'
SYS.COM
creates bootable disks. By removing SYS.COM, the files become worthless
(unless you knew an alternate method to construct a bootable disk without
SYS.COM).
