- Suppressing the Serial Number Search on Drive A:
- for Symphony 1.1
-
- NOTE: THE METHODS DESCRIBED BELOW APPLY ONLY TO THE VERSION OF SYMPHONY
- 1.1 PRODUCED BY THE "COPYIIPC" ARCHIVAL BACKUP PROGRAM. DO NOT ATTEMPT
- THE FOLLOWING STEPS IF YOU HAVE NOT BACKED-UP UP YOUR SYMPHONY 1.1
- PROGRAM DISK WITH COPYIIPC.
-
- A number of people are under the impression that Symphony 1.1 must
- still search for the serial number of the key disk even after having
- used COPYIIPC to make a backup copy that will run from a hard disk.
-
- This is not necessarily true, and it proves that it pays to read the
- documentation that programs come with. COPYIIPC includes a program
- called NOKEY which, if executed prior to running Symphony 1.1, will
- prevent the serial number search to drive A:. If fact, NOKEY even
- supplies a serial number of 0's for Symphony to display on the opening
- screen.
-
- But even if you use NOKEY, you may still encounter problems. There
- is a situation in which NOKEY will not work properly. If you use
- Sidekick, the "ACCESS" program to start Symphony 1.1 together with NOKEY
- you will get a message "cannot find file COMMAND.COM". You have to stop
- using either NOKEY or ACCESS to run Symphony 1.1 successfully from a
- hard disk.
-
- Luckily there is a way to get aroung this problem. As a minor side
- benefit, you will no longer need to use NOKEY to stop the serial number
- search. You will be making a slight modification to the file
- "SYMPHONY.EXE". Note that this file is created by COPYIIPC. Do not
- modify any other file!
-
- Follow the DEBUG instructions below. After you finish, Symphony 1.1
- will not go to drive A:. Since Copyiipc has already removed the
- Softguard protection, this means Symphony 1.1 is usable from a hard disk
- without any dependence on your floppy drive.
