SYS

Creates a startup disk by copying hidden MS-DOS system files (IO.SYS and
MSDOS.SYS), the MS-DOS command interpreter (COMMAND.COM), and the part of
MS-DOS that provides access to compressed drives (DRVSPACE.BIN) to the disk.
(SYS copies DRVSPACE.BIN only if the DRVSPACE.BIN file exists in the root
directory of the source drive or directory.)

IO.SYS, MSDOS.SYS and DRVSPACE.BIN are hidden files and do not typically
appear when you type the DIR command. To see these files, type DIR /A.

Syntax

    SYS [drive1:][path] drive2:

Parameters

[drive1:][path]
    Specifies the location of the system files. If you do not specify a
    path, MS-DOS searches the root directory on the current drive for the
    system files.

drive2:
    Specifies the drive to which you want to copy the system files. These
    files can be copied only to a root directory, not to a subdirectory.
