SYNOPSIS
The Configuration Control Program (CCP) is a system access,
boot, and configuration control program for MS-DOS and PC-DOS
based systems. CCP provides secure access, boot protection,
configuration locking, and optional hard disk password
protection.
The CCP installation program installs a new master boot
record (MBR or partition table) on the hard disk. The original
MBR is copied to a hidden file on the hard drive and to a
floppy diskette for recovery purposes.
The new MBR prevents access to the hard disk when the
system is booted from a diskette, password-protects the hard
disk on boot-up, and/or prevents booting if changes have been
made to the CONFIG.SYS or AUTOEXEC.BAT files without supervisor
approval -- a feature for standardizing configurations in
corporate environments. The supervisor selects which features
the new MBR will have.
CCP Version 1.1 works on any system with 512Kb of
memory and DOS 3.3 or greater. One floppy disk is required
for each system CCP is installed on. CCP is not compatible
with DOS 2.nn systems, systems partitioned with a third-party
disk partitioning program such as SpeedStor or Disk Manager, or
systems with a 'dual boot' partition, such as DOS-Unix or
DOS-OS/2. It is not compatible with DR-DOS. CCP is not
compatible with Windows 3.1 '32BitDiskAccess' (or FASTDISK)
feature. Change your WIN.INI file to read 32BitDiskAccess=OFF
if it does not currently read this.
Version 1.0B checks for the use of disk compression
programs to prevent disk interrupt conflicts, and performs
integrity checking before restoring the original partition
from the backup disk.
CHANGES
Version 1.1 contains fixes for bugs which occurred during
attempts to update or reinstall CCP.
NOTE: CCP Version 1.1 is backwards-compatible with Version 1.0.
However, CCP Version 1.1 can not be uninstalled with CCP
Version 1.0.

AUTHENTICITY
CCP is packaged with the VALIDATE program to ensure the
integrity of the CCP files. The VALIDATE.DOC file tells how
to use VALIDATE. VALIDATE can be used to check subsequent
versions of CCP for tampering.
The validation results for Version 1.1 should be:
FILENAME SIZE DATE CHECK METHOD
CCP.COM S:9,499 D:07-21-92 M1: E5E3 M2: 17FC
CCP.MBR S:39,361 D:12-04-92 M1: E658 M2: 0BE5
If your copy of CCP differs, it may have been damaged (or the
CCP.MBR file may have been pre-configured by the system
administrator). Always obtain CCP from a known source, such as
McAfee Associates, its Agents, or the person responsible for
computer security in your organization. The latest version of
TCM and validation data for its programs can be obtained from
McAfee Associates' bulletin board system at (408) 988-4004, from
McAfee Virus Help Forum on CompuServe (GO MCAFEE), or by
anonymous ftp from the mcafee.COM site on the Internet.
All of McAfee Associates' programs have been archived
with PKWare's PKZIP Authentic File Verification. If you do
not see an "-AV" after every file is unzipped and receive
the "Authentic Files Verified! # NWN405 Zip Source: McAFEE
ASSOCIATES" message then do not use them.
If your version of PKUNZIP does not have verification
ability, then this message may not be displayed. Please
contact us if you believe tampering has occurred to the .ZIP
file.

CCP OVERVIEW
CCP installs a custom Master Boot Record (partition table)
onto the first five sectors on the hard disk, an area of the
disk that typically remains unused.
The MBR installed by CCP can be configured to perform
several functions: It can prevent access to the hard disk when
the PC is booted from a floppy, prompt the user for a password
when the system is booted from the hard disk, and lock the
system when changes have been made to the CONFIG.SYS and
AUTOEXEC.BAT files.
The MBR will also prevent accesses to the first five (5)
sectors of the hard disk which contain its code. Access to
this area while CCP is active will show the original (pre-CCP
installation) MBR. CCP will prevent any changes from being
made to this part of the disk.
NOTE: When CCP's custom MBR is installed and running, it will
reduce the amount of total conventional memory available
to the system by 1,024 bytes. Thus, a system with 640Kb
of memory (655,360 bytes) will report that it has 639Kb
of memory (654,336 bytes) available.
When CCP is installed, it will save the original MBR to
a floppy diskette as a backup. The floppy disk should be
clearly labeled as a CCP RECOVERY DISKETTE and write protected.
Be sure to write the user's name, department, PC serial number
and any other important information on the label. CCP will
also create a hidden file in the root directory of the disk
containing the first five sectors of the hard disk. The file
is named ▒≡DISK≡▒.IDN.
NOTE: Do not install or run CCP while disk caching software or
hardware is in use. CCP performs direct writes to the hard
disk which may not be handled correctly by disk caching
algorithms. Use of disk caches while installing CCP via
the CCP.COM program may result
