INTRODUCTION
============
FSK Security System is a password protection program for a personal computer.
After this program is installed only the person knowing the password you have
selected can boot up your computer.
FSK Security System has two passwords that you select. SYSTEM password needed
to boot up the computer. And the CONFIG password needed to change the system
password.
This way when you give someone your password to use the computer, that person
can no longer lock you out from your own computer by changing the access
password.
Features :
- 1 to 40 character passwords
- separate password required to change the system password
- passwords are not case sensitive
- passwords are never displayed on the screen
- passwords are stored in the encrypted file
- simple program to change passwords
- system locks after 4 invalid access attempts
- Ctrl Break and Ctrl C sequence disabled
Before installing FSK into your autoexec.bat file you must first run
INSTALL.EXE to initialize the FSK, create data file, and select the passwords
for the first time.
The computer freezes after four unsuccessful system password entries, or after
two unsuccessful config password entries.
Four attempts are given since the back space button is disabled.
FIRST TIME INSTALLATION
=======================
After obtaining the .zip file with FSK program, create a directory.
type MKDIR \FSK
Copy all files of the program into that directory.
type COPY *.* \FSK
You should have 4 files at this time: FSK.EXE, CONFIG.EXE, INSTALL.EXE, and
FSK.DOC (this file). Change the current directory to the one you have just
created and plan to run FSK from.
type CD \FSK
Run INSTALL.EXE program to initialize configuration file.
type INSTALL
Blue screen will appear asking to enter your SYSTEM password. Type the
password that you want to boot up your computer with. Press <enter>, and the
prompt asking to confirm system password. Retype the system password to make
sure that you did not make a mistake, since the password you typed in is not
displayed on the screen (for security reasons). Press <enter>, and the prompt
asking to enter CONFIG password will appear. Type here the password that later
on will be needed to change the passwords. After pressing <enter> the program
again ask you to confirm config password. Retype the config password and press
<enter>.
If the confirm password you entered is not identical with the one entered
previously, the program displays a warning and ask you to enter the password
again.
After this program ends you will have 5 files in the directory, the files will
be: FSK.EXE, CONFIG.EXE, FSK.CFG, REGISTER.FRM, and FSK.DOC (this file).
After running install.exe add 3 lines to the beginning of your
AUTOEXEC.BAT file :
CD d:\path (drive and path of the directory were this program
is located)
FSK
CD \
FSK cannot be executed through the path or by d:\path\FSK.EXE, but the actual
directory of the program must be entered. This is because the program reads
the FSK.CFG (configuration file) from the current path.
REGISTRATION
============
To register your copy of FSK: print REGISTER.FRM, fill out the information
requested, attach the check or money order for 5.00 US dollars made payable to
VLADIMIR KILIN, and mail it to the address given at the end of this document.
When your check is received you will be sent a code after entering which, all
delays and registration reminders will disappear forever.
If you do not have a printer it is important that the program's serial number
appears on the paper that you will send me, since the registration code that is
sent to you depends on the program's serial number and can register only that
copy of the program. This number can be found in REGISTER.FRM file or in the
program itself by typing /? instead of the system password at boot up time.
