40 OR MORE HOURS OF SINGLE STEPPING THRU CODE AND FIGURING OUT THE

INTENT OF THE ORIGINAL CODE.. SO I WOULD APPRECIATE IT WHEN U PASS

THIS ON TO OTHER BOARDS YOU DO NOT ALTER THIS OR TRY TO TAKE CREDIT

IF YOU HAVE A HARD DISK OR WANT TO CREATE A BACKUP COPY THAT IS NOT
TIED INTO THE PC-DRAW DISKETTE...IN CASE YOUR ONLY COPY GOES BAD
.. THIS PATCH WILL REMOVE THE COPY PROTECTION COMPLETELY....

AS ALWAYS THIS IS FOR YOUR PERSONAL PEACE OF MIND ONLY
IT IS NOT MEANT TO BYPASS ANY COPYRIGHTS..YOU ARE BY LAW BOUND BY
YOUR PURCHASE LISCENSE AGREEMENT.

IF YOU HAVE A HARD DISK AND WANT TO PUT THE PROGRAM ON SUCH
WHY SHOULD YOU BE TIED TO A FLOPPY. YOU HAD TO GIVE UP A LOT OF
'BIG MACS' TO GET YOUR HARD DISK.

THIS WRITE UP ASSUMES THAT YOU ARE FAMILIAR WITH DEBUG,

1). FORMAT A CORRESPONDING EQUAL NUMBER OF DOS2.0 OR 2.1 DISKS
AS SYSTEM DISKS

2). LABEL EACH OF THE 2.X FORMATTED DISKS THE SAME AS EACH ONE OF
THE ORIGINAL 'PC-DRAW' DISKS

3). COPY THE FILES FROM THE ORIGINAL DISKS TO THE 2.X FORMATTED DISK
ON A ONE FOR ONE BASIS, USING 'COPY' COMMAND

4). PLACE THE ORIGINAL DISKS IN A SAFE PLACE, WE DONT NEED THEM ANY MORE.

5). PLACE 'DISK 1' IN THE 'A' DRIVE

6). RENAME DIAGRAM.EXE DIAGRAM

7). DEBUG DIAGRAM

8). YOU NOW NEED TO NOP A RANGE OF SEVERAL INSTRUCTIONS AS FOLLOWS

9). FIRST YOU SHOULD SEE THE FOLLOWING CODE AT ADDRESS

IF U DONT U MAY HAVE A DIFFERENT VERSION SO DONT PROCEED ANY FARTHER,
BUT FIRST DO A SEARCH FOR THE FOLLOWING CODE:

10). S CS:100 L EFFF CD 13 72 21



CD13 INT 13
7221 JB ZZZZ ;WHERE ZZZZ IS AN ADDRESS, MINE WAS 'B2C6'

DEBUG WILL RETURN THE ADDRESS WHERE THE STRING IS FOUND IN THE FORM

XXXX:YYYY MY ADDRESS WAS 8F1:B2A1


ENTER THE CHANGE TO CHANGE "INT 13" TO "STC" AND "NOP", THIS WILL FORCE
A JUMP TO THE NOP'S TO BE ENTERED BELOW


11). E YYYY F9 90

MY 'YYYY; WAS 'B2A1'

12). AGAIN USE THE ADDRESS AT 'ZZZZ' ABOVE TO DO STEP 13.

13). E ZZZZ 90 90 90 90 90 90 90 90 90

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
