- Protection System PROT.EXE by Data Rx.
- Copyright (c) 1992 by Data Rx
-
- Written by U.F.M. Software (92) All rights reserved.
-
- PROT.EXE is a small protection program which is very easy to install.
- PROT.EXE safely locks your PC and protects your data from unauthorized access.
- PROT.EXE is an unusual program. It is not listed in CONFIG.SYS, AUTOEXEC.BAT,
- or anywhere else. It runs automatically every time you boot.
-
- Upon boot up PROT.EXE asks for your 5-character password which you selected
- when you installed it. If someone wants to access PC, the password must be
- entered correctly before DOS can be loaded.
-
- PROT.EXE has four security modes: 0, 1, 2, 3. If the password is not entered
- correctly, the protected system will respond for each of the security modes
- as follows:
-
- Mode System's response
-
- 0 The PC's hard disks will be "frozen" (will not boot).
- The floppy drives (A: and/or B:) will work, so the PC can be
- started from a bootable floppy disk.
-
- 1 The PC's hard disks will be "frozen" AND the floppy drives
- (A: and/or B:) will not work. The PC can not be started from a
- bootable floppy disk. Restarting the computer and entering the
- correct password will provide access to both the floppy and hard
- drives.
-
- 2 The PC will boot from the hard drive and the hard drive will be
- accessible, but the floppy drives (A: and/or B:) will not work
- and nothing can be copied from the hard disk. Restarting the
- computer and entering the correct password will provide access
- to both the floppy and hard drives.
-
- 3 The PC will boot from the hard drive and the hard drive will be
- accessible, but the floppy drives (A: and/or B:) will not work.
- Furthermore, the PC can not be started from a bootable floppy disk.
- Restarting the computer and entering the correct password will
- provide access to the floppy drives.
-
-
- Do NOT try to change the CMOS setup to defeat PROT.EXE. PROT.EXE has not
- changed anything in CMOS. The PROT program is based on a detailed (and
- undocumented) procedure of DOS booting, not on the CMOS settings.
-
- PROT.EXE does not encode the master boot record (MBR) data area.
- PROT.EXE does not make use of hardware.
- In Modes 0 and 1, the only way the protected hard disk can be read
- without the password is by physically removing it and subjecting it to
- certain data recovery procedures. In Modes 2 and 3,
- the hard disk can be read, but nothing can be copied from it to floppies.

- Handy PROT.EXE Matrix
-
-
- Mode Can I Boot from floppy? I don't know the right password and
- Number I'm booting from the hard disk.
-
-
- 0 YES Computer's hard drive will freeze.
-
-
- 1 NO Computer's hard drive will freeze.
-
-
- 2 YES Computer's hard drive will work, but
- floppies will not work.
-
-
- 3 NO Computer's hard drive will work, but
- floppies will not work.

- How to install PROT.EXE
-
-
- 1 Turn off all caching software before installing PROT.EXE
- 2 Insert the PROT.EXE disk in your floppy drive. Log to the floppy
- drive.
- 3 Type the command PROT P <mode number>. As an example you could
- type PROT P 0 or PROT P 1. Note that there are spaces between PROT
- and P and between P and the <mode number>. Also note that the
- switch number is not enclosed in the pointy brackets <>.
- The P between PROT and the number stands for the protection mode
- you wish to utilize.
- 4 PROT.EXE will ask you for your password.
- Your password must be exactly five alphanumeric characters long.
- Uppercase characters are different than lower case letters.
- As an example: Captain Kirk's password "SPACE" is different from
- Mr. Spock's password "space" and Scotty's password "SpAce".
-
- 5 After you enter your password PROT.EXE will verify your password
- before allowing you to proceed.
-
- 6 Reboot after installation. PROT.EXE has been installed
- and your computer is protected.
-
-
- Other PROT.EXE Switches
-
-
- C use this <switch> if an attempt at installation results in the error
- message: "Track 0 Head 0 Sector 2 is not free"
- This error message means that PROT.EXE found something
- (either a virus or special coding) in your MBR. If you use the "C"
- switch. Example: PROT C. PROT.EXE will overwrite the data located
- on the MBR at Track 0, Head 0, Sector 2.
- Overwriting this data may result in total loss of access to
- the hard disk.
- Do not use the C switch unless you are certain you know what you
- are doing. You may never regain access to your hard disk without
- extensive data recovery procedures.
- Data Rx cannot be and will not be responsible for any losses
- that result from using PROT.EXE.
-
- U removes PROT.EXE and cancels protection (see WARNING below).
-
- Example: PROT U.
-
- ? for the help file. Example: PROT ?
-
- I for the help file. Example: PROT I
-
- H for the help file. Example: PROT H
-
-
-
- WARNING!
-
-
- Before installing PROT.EXE, turn off cache software.
-
- Before adding any new command(s) to your CONFIG.SYS file, remove PROT.EXE.
-
- If you forget to turn off PROT.EXE and protect modes 1 or 3 are on, AND if
- your PC for any reason does not support the new driver you are adding to
- your CONFIG.SYS file, your system will "freeze" and DOS will never load!
- The hard disk will have to be removed and subjected to extensive data
- recovery efforts.
