Making Backup Copies
It is important to make copies of all your data and system
diskettes. Make backup (or working) copies
contain programs, such as the original MS-DOS and Reference
diskettes that come with the Equity 386SX, and use only the
copies. Store the original diskettes in a safe place away from
your working diskettes.
Copy your data diskettes regularly, whenever you revise them,
to keep them up-to-date, and store them away from your
originals.
To make backup copies of your diskettes, use the DISKCOPY
command, the MS-DOS Shell, or the MENU program. See
Chapter 4, your Shell User’s Guide, or your MS-DOS Reference
Manual for instructions.
It is best to store the programs and data files you use regularly
on the hard disk. Keep backup copies of all your program files
on diskettes, and regularly copy important data files to diskettes
as well. See “Backing up the hard disk” in this chapter for more
information.
Note
Most files on your Reference diskette (including the Setup
and diagnostics programs) run properly only if you execute
them from the Reference diskette. If you have a hard disk,
copy only the following Reference diskette files onto it:
CORFIX.EXE, HDSIT.COM, HDSIT.VER, and
ROMBIOS.COM.
