Unprotect for ENABLE 1.00 and 1.01
If you have a hard disk or want to create a backup copy that is not
tied to the original ENABLE system disk, this will remove the copy
protection completely.
This procedure is to be used by legitimate owners of ENABLE only,
as you should make a backup for archive purposes only.
Format a blank disk (but don't use the /s option). Label it the same
as the original ENABLE system disk.
Copy the files from the original ENABLE system to the formatted
disk (*.*).
Place DOS system disk containing DEBUG in drive A:
Place the new copy of ENABLE in drive B:
DEBUG B:SYSTEM.TSG
S CS:0 L EFFF B8 01 04
(You should see either)
XXXX:069C
XXXX:XXXX < this one doesn't matter
(or if Ver. 1.01)
XXXX:0774
XXXX:0789
(If you don't, type Q and <ENTER> - you have a different version!)
Otherwise...
if you found XXXX:069C change 069C from MOV AX,0401 to JMP 0703
E 069C <ENTER>
B8.EB <SPACE> 01.2D <SPACE> 04.90 <ENTER>
W <ENTER>
Q <ENTER>
if you found XXXX:0774 change 0774 from MOV AX,0401 to JMP 07A4
E 0774 <ENTER>
B8.EB <SPACE> 01.2E <SPACE> 04.90 <ENTER>
W <ENTER>
Q <ENTER>
Now all the copy protection has been removed, and you may copy the
files as required.
All checks for specially formatted tracks have been disable.
