Disk Protection










































INTRODUCTION


Protek and the Test utilities allow a PC programmer to add
software protection to his/her distribution diskettes. While
Protek is fully functional, it is meant to be used strictly for
demonstrative purposes. The Shareware version of Protek allows
for protection of 360k 5" Floppy disks only.


PROTEK & TEST


Operation of Protek is straight forward. Type PROTEK to run
the program, and use the on-screen menu to select your task.

The first thing you must do, is to enter the security code
required to operate Protek, this is to stop unwanted parties from
using the program. Disks can easily be destroyed if unknowing
parties use this program. The Security code for the Shareware
distributed version is PROTEK, and may be entered in either
upper or lower case. When the correct Security code has been
entered, you will be able to select from the menu items. If an
invalid Security code is entered, the program will halt, causing
you to have to reboot your computer.

The menu consists of the following selections:

[Q] Quit the program back to DOS.

[A] Cylinder 39 protection in a 360k drive. This method of
protection prevents Diskcopy programs from duplicating
disks.

[B] Cylinder 39 protection in a 1.2MB drive. This selection
creates a disk protected similar to the above selection,
but must be used for 1.2MB high-density drive system.

[C] Cylinder 40 protection in a 360k drive. This method of
protection allows Diskcopy programs to make backups of
the original, but will not allow them to test properly
with the Test program. This is the preferred method,
since users can easily make an archival copy, but still
retain protection on the original.

[D] Cylinder 40 protection in a 1.2MB drive. This selection
creates a disk protected similar to the above selection,
but must be used for 1.2MB high-density drive systems.

[E] Format a new 360k disk in a 360k drive. The Format disk
feature is included to allow you to protect new disks out
of the box without having to bounce back and forth between
DOS's Format command and Protek.

[F] This selection is similar to the above, but is used for
1.2MB high-density drives.

[S] Allows you to select Drive A or B as the target drive for
Protection/Format operations.


Introduction - Protek and Test 1



Status displays show the current Date, in addition to the
current Drive, Cylinder, and Head numbers.


EXAMPLE


To demonstrate the Protek program, perform the following:

1. Copy PROTEK.EXE and TEST??.EXE to a new formatted 360k disk.

2. Run TEST40 and note that the message returned shows that
the disk is NOT protected.

3. Run Protek and select Cylinder 40 Protection on this disk.

4. Run TEST40 and note that the protection has now passed the
test.

The TEST39 program works similarly, except you must choose
Cylinder 39 Protection on the Protek program. Cylinder 40
protected disks can be copied using the standard DiskCopy
programs, but will always prevent the test from passing.
Cylinder 39 programs will show an error when using standard
DiskCopy progams.
