BACKING UP YOUR HARD DRIVE:

Turn your system on.  You will need to have quite a few pre-formatted 
floppy diskettes on hand before you begin.  Type CHKDSK then press [ENTER].  
You will see a display similar to this:  

Volume MS-DOS_5      created 09-05-1994 12:53a
Volume Serial Number is 373B-07FF

 315645952 bytes total disk space
    557056 bytes in 68 directories
 185483264 bytes in 2099 user files
 129605632 bytes available on disk

      8192 bytes in each allocation unit
     38531 total allocation units on disk
     15821 available allocation units on disk

    655360 total bytes memory
    458896 bytes free

Add together the lines labeled "bytes in xx directories" and "bytes in
xxxx user files".  This is the total amount of disk space your files
occupy on your hard drive.  If you are using 360k diskettes for your 
backup, you will need approximately 3 diskettes per megabyte of occupied 
hard drive space.  For 720k diskettes, about 1.5 diskettes per meg will be 
needed.  For 1.2 meg diskettes, well, a little over a meg will fit on
one diskette.  As for 1.44 diskettes, just under 3 megs fit on 2 diskettes,
so add a few extra to your total for good measure.  Make sure you have
enough diskettes ready, as you will not be able to format more once you
start.

From the C: prompt, type CD\.  This will assure you are in the root directory 
and that your entire drive will be backed up.  Now, type the following:

C:\DOS\BACKUP C:\*.* A: /S [ENTER]   to backup to your A: drive
C:\DOS\BACKUP C:\*.* B: /S [ENTER]   to backup to your B: drive

The system will prompt you "Insert backup diskette 01 in drive A:".
It will also give you a warning that all data on this diskette will
be erased.  Put one of your blank diskettes into the drive and press
[ENTER].  The system will begin writing a copy of your hard drive to
the diskette.  Once this diskette is full, you will see "Insert backup
diskette 02 in drive A:".  Remove the first diskette and label it
C: BACKUP 01 and put today's date on it.  Put another blank diskette
into the drive and press [ENTER] again.  Continue removing and labeling
the diskettes until your entire drive is backed up.  A message on the
screen will inform you when the backup is complete.  It is recommended 
you store the backup at another location if your data is important (such
as business records).  Use the same command to backup other drives,
replacing C: with the drive letter you wish to make a backup of.
