              How To Unprotect:  ATI Training Software              JRE
==========================================================================

         This information is provided to allow legal owners of the
    above software to liberate themselves from the dependence of a
    single floppy diskette.

         Using the below patches, you will be able to make unlimited
    backups of the floppy, but more importantly, be able to boot the
    entire system off a hard disk.

         The copy protection method used on this program expects an
    unusually formatted Track 2.  The easiest way around this
    was to patch the 'Verify Track' routine.

         When you run the unprotected copy of Chart Master, you will
    get an error message.  You can ignore this an just press <ENTER>.
    I'm sure that this can be bypassed also, but after running the
    program, I was disappointed and decided not to spend any more
    time debugging it.  If you can eliminate this shortcoming, feel
    free to modify this file and upload it to your favorite BBS.

         I assume that you are familiar with DEBUG (found on the 2nd
    DOS diskette).  Everything displayed below in upper-case will be
    supplied by the computer; you must type everything that is in
    lower-case.  Note that the '-' is DEBUG's prompt and should not
    be typed.  Make a copy of the file 'ATI.EXE'; never work
    with you only copy.  Place the program diskette in Drive A,
    and Debug in Drive B.

                                   /------ Comments -------------------
   A> ren ati.exe ati              | Debug can't resave an EXE file
   A> b:debug ati                  | Enter Debug
                                   |

   -q                              | Exit DEBUG
A> ren ati ati.exe                 | REName the file to it's original name

   Thats It.  Use 'COPY A:*.* B:' to move all files to a formatted
diskette and you will have the whole system unprotected and copyable.
