Restoring M S-DOS System Files
You cannot restore system files without having first created
the backup diskettes. If your system is down, you cannot
create these diskettes. It is very important to create
backup system diskettes as soon as possible after the
purchase of your computer. Refer to Chapter 1,
Creating
Back Up System Diskettes
.
The
MS-DOS
files
COMMAND.COM
,
IO.SYS
,
EXTMSDOS.SYS
, and
MSDOS.SYS
are necessary for the operation of your
computer. If any of these files is accidentally deleted or
modified, your computer will not function as designed. This
section describes the procedure for restoring these files
without affecting the applications and data files that may
be on your hard drive.
If you need more information, see the
MS-DOS User’s Guide
