DOCUMENTATION TO PASSWORD.SYS VERISON 1.1


PASSWORD.SYS enables you to protect your Harddisk or Floppydisk from
not welcomed Users. If you have the problem that several people enter
your system without your permission, and you are sick of that, then you
could find this little program useful.
It asks for a PASSWORD (maximum 40 characters long), and repeats until
the correct password is typed in or halts your machine if the password
isn't valid after the fourth try. The password is quite sure and very hard
to break - so don't worry, that a Hacker could enter your machine. The
difference to other commercial products is, that it is written as a
device driver, which means, one cannot interrupt its Code. There are only
two ways: one: Reenter the password or switch off the computer. there's of
course too the posibilty to access via the Floppydisk and alter the Config.sys
file, but for normal use its quite save.
I just wrote this program to test the devicedriver possibilities of MSDOS.
This program does nothing exept asking for a password, and lock the computer,
if no one right is typed in. It doesn't cut off any of your valuable RAM.

Installation

1) Copy PASSWORD.SYS and SETPASSW.EXE to your root-directory (or utility
   directory, if you have got one).
2) Load the file CONFIG.SYS (in the rootdirectory of your bootdrive) into a
   texteditor(only ASCII-TEXT) and insert the Following as the first in
   CONFIG.SYS:

          DEVICE=C:\PASSWORD.SYS

3) After doing this reboot your Computer. Now should be the Pasword-prompt
   on your screen. The default-password is "GUEST". Enter it now; be care-
   ful: the program works case-sensitive, that means that GueST and GUEST
   aren't the same (like in C and Modula-2).

4) If you like to change the Password, then use the program SETPASSW.EXE,
   which comes with PASSWORD.SYS. First you have to enter the correct
   password and then yu can enter a new one. Write it down and store it
   in a save place, so that if you forget your password you could look it
   up.

There are some tips using Passwords:

 -) You should change your password regularly (e.g. each week).
 -) Use random combinations of Letters and numbers; then you could be
    quite secure, that no one will be able to hack in.


If you find this program useful and like it, then be so kind and send me
something for it, so that I get more ideas to develope my program (I'm
thinking of Directory access rights etc...). A little gift would be
appreciated in the range from US 5$ to US 10000000$. If you register then
you get always news about new products and updates for this one.

THIS PRODUCT IS SHAREWARE - YOU ARE ALLOWED TO HANDLE IT TO YOUR
FRIENDS AND OTHERS BUT ONLY IF NOTHING IN THE PROGRAMS OR THE DOCUMENTATION
IS ALTERED. I DON'T CHARGE FOR ANY DAMAGES, THE USE OF THIS PROGRAM MAY
CAUSE. ALTHOUGH IT IS PROGRAMMED TOTALLY CLEAR ERRORS CAN'T BE EXCLUDED.
IF SUCH ERRORS OCCUR, AND YOU ALLOCATE THE ERROR THEN PLEASE SEND A MAIL TO
ME.

MAIL.Address:
  Because I don't have an account for myself, I have to use the address of
  a friend of mine. He'll send the mails to me after that. His address:

REMARKS:
  Version 1.1 now enables hidden input of Passwords; not as the Version
  1.0 did, which echoed the String to the screen. Now for each Character
  a '*' is displayed. you can edit your input as you are used to it.
  The first Release of my program was a test, if it would be useful for
  other users. after a mail fron Mr. Salmi from GARBO i got encouraged to
  develope my program more. Next versions will have the option to switch
  the screenprompt between several languages (spanish, french, german,
  italian, and english).

  Bueno amigos, ­hasta lugo!
