How To Unprotect: Electric Desk 1.04 JRE
==========================================================================
This information is provided to allow legal owners of the
above software to liberate themselves from the dependance 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 9. The easiest way around this was to
bypass the entire 'Verify Track 9' 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. Make a copy of the file 'ELECTRIC.EXE'; never work
with you only copy. Place the program diskette in Drive A,
and Debug in Drive B.
/------ Comments -------------------
A> ren electric.exe electric | Debug can't resave an EXE file
A> b:debug electric | Enter Debug
-r cs | Get CS from debug (always different)
CS XXXX | Add 2000 to the number returned
| by DEBUG. This becomes yyyy.
: <return key> | Example: CS 2502, + 2000 = 4502 (yyyy)
-s yyyy:0 ff00 b8 00 bf 78 | Use above calculated yyyy in this line.
YYYY:D145 | DEBUG should return this number. If not,
| you have a different vers & should quit.
-e yyyy:d145 e9 b0 00 00 | Tell prog to skip copy prot. routine.
-w | Save the program with the changes.
Writing 2D230 bytes | DEBUG displays this message.
-q | Exit DEBUG
A> ren electric electric.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.
