The SYS command is used to transfer a copy of the DOS operating system files
from the default drive to the specified disk drive.  The command format
is as follows:

           SYS d:

The target disk in the specified drive must be completely empty or be formatted
using the /S or /B options of the FORMAT command (see the help file FORMAT for
details).  DOS requires its startup files to be the first two directory entries
in the root directory of the disk, and the file IBMBIO.COM must be contiguous
(see the help file FRAGMENT for information about contiguous files).

If SYS cannot place the system files in valid directory positions, an error
message is displayed on the screen and the files are not transferred.
