Documentation for SAVEIMAGE

                      Copyright (c)1998 by Tim Tesch


PURPOSE:
--------
       SAVEIMAGE was written so that Geneve users could save images of
       their hard drives (HFDC or SCSI) as files to _any_ device.  Saving
       the image to a file instead of to specific sectors on the hard drive
       improves your chances of recovering from a sector zero error.  Users
       of CFORM who format to 34 sectors per cylinder will also be able to
       restore their hard drives, something not possible with the embedded
       MDOS Mirror command.

USAGE:
------
       SAVEIMAGE is a small MDOS program used from the DOS prompt or within
       a batch file as follows:

            SAVEIMAGE <inputdevice> <outputfile>


E X A M P L E S:
----------------
Assumptions:        A:  = DSK1
                    E:  = HDS1
                    F:  = HDS2
                    G:  = SCS1


            SAVEIMAGE F: A:\SAVEHDS1         save image of HDS2. to file on DSK1
            SAVEIMAGE G: F:\SAVESCSI1        save image of SCS1 to file on HDS2
            SAVEIMAGE HDS1. HDS2.PLOP1       save image on HDS1 to file on HDS2

THE IMAGE FILE:
---------------
       The image file contains sector zero and the accompanying bitmap.  I
       was tempted to simply save sector zero since you never know if the
       bitmap is correct when restored... But I left it alone :)-

       IF YOU TRY TO RUN THE IMAGE, IT WILL TELL YOU THAT IT IS AN IMAGE
---->  AND IT WILL INFORM YOU WHICH HARD DRIVE THE IMAGE CAME FROM, the
       DATE AND TIME CREATED, AND THE VOLUME NAME.

       Here is how the IMAGE FILE is set up:

            SECTOR       DESCRIPTION
            ------       -----------
               0         small bit of MDOS code, tells you that you are
                         trying to run an image.
               1         This is sector zero of the hard drive
             2-33        these are the bitmap sectors


RECOVERY:
---------
       I did not release the LOADIMAGE program as I do not feel comfortable
       releasing such a program without building in some security.  I find
       it would be TOO EASY for someone to overwrite their hard drive
       bit map/sector zero using a simple utility.

***    If you would like me to release the program, let me know.  Otherwise,
*****  you need only format the first cylinder of your hard drive and copy
***    sector 1 from my image to sector 0 of the hard drive and so on...
