If you are like me, you have information contained in your PC that
should not be made available for public consumption. The ^1PC Security^0
system can help you prevent easy access to your private data. Once this
system is installed, everytime the computer is booted you will be prompted
for a password. If it is not entered correctly, an alarm is sounded and
you will be prompted for the password again.
^1INSTALLING THE PC SECURITY SYSTEM^0
Use the "Copy It" command from the Big Blue Disk menu system to copy
PW.COM and SECUR.SYS to your bootable floppy or hard disk drive. These
files should reside in the root directory. Once the files have been copied,
either change your current or create a new CONFIG.SYS file. The first
line of this file should be DEVICE=SECUR.SYS.
^1WHAT IS THIS CONFIG.SYS FILE, ANYWAY?^0
When you first turn your computer on the system goes through a process
called "Booting Up". This "Boot Up" procedure includes system testing,
loading of the operating system into memory (IO.SYS and MSDOS.SYS files),
and starting the command line interpreter (COMMAND.COM which interprets and
executes the commands that you enter at the DOS prompt). Before the command
line interpreter is started, the computer looks for a file in the root
directory of your bootable disk called CONFIG.SYS. This file is used to
CONFIGure your system. A typical CONFIG.SYS file might have the following
information:
DEVICE=SECUR.SYS
FILES=20
BUFFERS=20
DEVICE=MOUSE.SYS
BREAK ON
NOTE: If you intend on using PC SECURITY, the only line that is required in
your CONFIG.SYS file is DEVICE=SECUR.SYS.
^1REMOVING THE PC SECURITY SYSTEM^0
If you decide you no longer want to use PC SECURITY, you must remove it
from your CONFIG.SYS file. If the only line in your CONFIG.SYS file is the
line, DEVICE=SECUR.SYS, then you can simply delete the entire CONFIG.SYS
file. However, if the file has other commands in it, only remove the
"DEVICE=SECUR.SYS" line.
^1USING PC SECURITY^0
Once you have installed PC SECURITY on a disk (either floppy or fixed),
everytime you start your computer from that disk you will be prompted for
the system password. PC SECURITY comes installed with an initial system
password of "bootup". However, you may change it at any time by running
the PW.COM program. When you enter a password the characters will NOT be
echoed to the screen and you will not have to press the ENTER key when you
are finished.
NOTE: When you are prompted for a password you must be sure and enter it
in the same case as you entered it initially. For example, if the
password was "BOB" and you entered "bob", the program would sound
the alarm and prompt you again for the password.
^1CHANGING THE PASSWORD^0
Once you have started the system, the password can be changed by running
PW.COM. Type PW.COM at the DOS "*>" prompt. You will be prompted for the
master password (the initial master password is "bootup"). If you enter an
incorrect value, the program exits without making any changes. After the
correct master password is entered, you will be allowed to change both the
system and master passwords. You will be prompted for the system password
initially. Once the this value has been changed, you will be prompted for
a new master password. The process of entering a new master password is
the same as for the system password. In both cases the system and master
passwords are limited to ten characters each.
