What's New
This file contains a brief listing of new features and other
changes from PC-Vault 4.4w. If you are not already familiar with
version 4.4w, please skip this file and read your Administrator's
manual.
New In PC-Vault and PC-Vault Plus Version 4.5
The implementation of Maximum Floppy Boot Protection is
completely new and uses totally different techniques from those
used in prior versions. It will be much more secure against a
hacker who is trying to break in. In addition, we expect it will
be more compatible with today's variety of disks, controllers,
and software.
Substantially improved compatibility with OnTrack's Disk Manager.
Except on XTs, use of Password Ageing no longer requires that
PC-VAULT.EXE be resident on the hard drive, nor does it require
the PC-VAULT/A statement in AUTOEXEC.BAT.
The administrator can prohibit users from changing the system
date and time. Note: It is always possible for a program to
write CMOS memory directly, but we do not know of any that do.
In any event, the clock regression rules will cause all passwords
to expire if the clock has regressed by more than four hours.
(See menu item T in Select Options.)
When selecting password ageing, the administrator can choose
whether or not the administrator password will expire.
HelpUser can now be used to grant either Administrator, or User 1
access to a PC.
WHO /L will display the name of the current user.
WHO /E will cause an environment variable to be defined:
PCVU=username. This is very useful in batch files. Example:
CD \%PCVU%
The number of users in addition to the administrator has been
increased to 12.
The LOGOFF utility has been added. Running LOGOFF will log you
off of the computer, and give another user the opportunity to
logon without rebooting. Simply type LOGOFF at the DOS prompt.
After the new user logs on, the DOS prompt will re-appear. The
default drive will be the one from which DOS was booted. The
default directory will be the root directory.
It is no longer necessary to use the special display blanking
option with Windows and VGA.
The Windows 32 bit disk driver (also known as FastDisk and
WDCTRL) will now load and work correctly.
If one of the following comments is placed in the CONFIG.SYS file
prior to installing PC-Vault, PC-Vault will place its DEVICE
statement on the line following the comment.
REM CLEANDSK.DRV HERE
REM CLEANDSK.DRV HERE (HIGH)
REM CLEANDSK.DRV HERE (SPECIAL,TEXT)
The second comment line will cause PC-Vault to use a DOS 5.0
DEVICEHIGH statement. This feature makes removal and
reinstallation of PC-Vault easier in those situations where the
device statement should not be first, or where a special device
statement is required by a memory manager such as QEMM. Please
see the administrator's manual for additional information.
If a virus invades your master boot record (boot sector) or it is
otherwise trashed, PC-Vault will recognize the condition and ask
if you would like for PC-Vault to rebuild it for you.
VIOLS /L will now display the date and time of the user's last
logon. This will alert a user that someone else knows his/her
password and uses the computer at times when the legal user is
away.
If the administrator states that the person installing PC-Vault
is to be the administrator (See PC-Vault /P in your manual), he
may also require that the administrator password be entered
before PC-Vault will install. This will prevent unauthorized
persons from installing PC-Vault, and ensure that the installer
knows the administrator password.
See also the "New in the EXEC Program" below.
New In PC-Vault Plus Version 4.5
A new line on the Directory Access Control screen allows the
administrator to control each user's permissions will have to new
level 1 sub-directories between their creation and the time when
he actually assigns permissions to them.
Execute access is both necessary and sufficient to execute
programs under Windows (this is a bug fix).
The log file, ACCESS.SYS, is now a locked file. FLUSHLOG now has
a /U switch which unlocks the log file. If you delete or rename
the log file a new locked log file will be created when new
entries need to be added.
The global .EXE/.COM access control has been replaced with
control for each root & 1st level directory. (See the PC-Vault
Plus main menu's D option.)
Directory permissions will be remembered across removal and
subsequent re-installation.
Directory permissions changes are effective immediately. No
re-boot is required unless total number of root and first level
sub-directories has been increased since the last boot. In this
case, an informative message will be displayed.
Changes in file accesses to be logged are effective immediately.
New in the EXEC Program
Two new parameters have been added to the EXEC program. Their
use is somewhat technical, and most users can skip the following
description. The EXEC command line now has the form:
EXEC [/R] [/Ln] [/Tn] /drive:\full_path_name\prog.ext param-list
The new parameters, /L and /T allow the program started by EXEC
to execute other programs. /Tn allows a total of n programs to
be executed, additional execution attempts will fail. The n may
be any number from 0 (the default) through 9. This parameter is
necessary to start Windows 3.1, for example, because it asks DOS
to execute 2 or 3 programs (Standard or 386 modes) during its
startup. Once started windows could execute any number of
Windows programs, but no DOS programs since that would exceed the
selected value of a properly chosen n.
The /Ln parameter allows the program started by EXEC to execute
another program, which may execute another program, etc. to a
depth of n levels. Thus if EXEC /L1 started a menu program (level
0), the menu program could execute any number of other programs
(all at level 1). The level 1 programs started by the menu
program could not execute any other programs because a depth of
level 2 would not be allowed. The n may be any number from 0
(the default) through 9.
You may not use both the /L and /T parameters.
