========================================================================== 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. : | 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. ========================================================================== Originally Uploaded To: Rail Road BBS New York JRE ========================================================================== Dec. 6, 1985: From:TOP CAT Rbbs, Springfield, MA Subject: addendum -------------------------------------------------------------------------- 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 , and type: -e yyyy:CF3D 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" . -------------------------------------------------------------------------
