How To Unprotect: Aardvark McGraw-Hill Financial 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 7. The easiest way around this was to
bypass the entire 'Verify Track 7' routine.
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. Place the program diskette in Drive A, and Debug
in Drive B. The following example applies to 'Estate Tax Planner'
but the same theory seems to apply to all in the series.
/------ Comments -------------------
A> b:debug est1 | Enter Debug
-r cs | Get CS from debug (always different)
CS XXXX | Add 1000 to the number returned
| by DEBUG. This becomes yyyy.
: <return key> | Example: CS 2502, + 1000 = 3502 (yyyy)
-s yyyy:0 ffff e8 a 0 75 5 | Use above calculated yyyy in this line.
YYYY:CF3D | If DEBUG does not return this number, add
| another 1000 and retry.
-e yyyy:cf3d 90 90 90 90 90 | Tell prog to skip copy prot. routine.
-w | Save the program with the changes.
Writing 1E000 bytes | DEBUG displays this message.
-q | Exit DEBUG
Thats It. Use 'COPY A:*.* B:' to move all files to a formatted
diskette and you will have the whole system unprotected and copyable.

If you are like me, and you follow the above directions verbatim, you will
never succeed in unprotecting the AARDVARK software. In the step above
where you are waiting for the computer to return CF3D, it does NOT have to
be CF3D. On my software, it was something totally different. So...the
proper step, in my case, was to take the value returned: YYYY:CF3D <or
whatever value appeared>, and type:
-e yyyy:CF3D <or whatever value appeared above> 90 90 90 90 90
in place of what the program tells you above.
C A U T I O N: IT IS HIGHLY RECOMMENDED THAT YOU USE THIS PROTECTION
SCHEME ON A *BACKUP* COPY OF YOUR SOFTWARE, IN CASE
YOU HAVE A PROBLEM. UNDER NO CIRCUMSTANCE SHOULD YOU
USE THIS ROUTINE ON AN ORIGINAL FLOPPY.
I DID THE ROUTINE ON A COPY CREATED BY QUAID SOFTWARE'S
"COPYRIGHT" <A PROGRAM I HIGHLY SUGGEST YOUR PURCHASING>.
