& AbsoluteBoot 2000
Does your IT service spend too much time reinstalling Windows NT or 2000
and the applications following a false user manipulation, or as a result
of the installation of software which makes the machine hang, or following
slowing down or malfunctioning of the computer? The proper functioning
of workstations is even more crucial in educational establishments or
training centres, where machines are used by a large number of inexperienced
users but where they have to always be in an operating condition.
Beyond a concern for control of the total cost of ownership ( TCO
) associated with the use of a large number of PCs and laptops in the
company, the IT personnel in-charge are confronted with problems of reliability
and complexity of configurations. Indeed, even if the 'plug-n-play' technique
makes the installation of PCs increasingly easy, the operating systems
and the applications offer such a variety of configurations and options
that this flexibility is rendered counter-productive by a more difficult
and expensive management of the pool.
Additionally, increased risks are to be taken into consideration when
the non specialist users install a new application on their PC altering
the integrity and the safety of the computer system. Indeed, Windows is
such an open and complete system that the installation of new applications
and certain peripherals become much simpler and therefore impossible to
The AbsoluteBoot and AbsoluteBoot 2000 solution
AbsoluteBoot is a unique and innovative solution developed specifically
to meet these needs of reliability and simplification of workstations,
while securing the operating system and the applications.
Launched in 1998, AbsoluteBoot enables you to 'boot' (start) Windows
NT and 2000 on any computer, with or without a hard drive ('diskless'),
from either the server of a local network, a CD-ROM, a CompactFlash card
or the hard drive, and to execute the OS and applications in RAM memory,
thereby making any system writing 'virtual'. The OS/applications file
contains all that the user needs to execute the applications immediately,
without reconfiguring the local system or touching the network.
AbsoluteBoot is based on a unique technology, VMA
(Virtual Media Architecture), developed by APCT to guarantee the
proper operation of PCs under all circumstances. VMA architecture
differs from a traditional architecture by the re-direction, during the
execution of the programs, of the access to the C: drive (or any other
boot media) towards a virtual disk which gets installed in RAM memory.
Thus, the media is only accessed in Read mode and any modification of
the configuration (which includes the registry) will only be effective
until the next loading of the system. A simple ' reboot' of the machine
is enough to restore the clean configuration.
Thanks to the execution of programs from a protected and stable image,
AbsoluteBoot makes the work environment secure and reliable. Calls
to the maintenance team are practically eliminated, reducing thereby one
of the principal costs of TCO.
More than 25000 AbsoluteBoot licences are used today by major accounts
or State organisations to develop and secure their computers, and to guarantee
their proper operation.
Security: AbsoluteBoot brings a new solution in terms of
hazard control by increasing safety at both user level, since its applications
are ' unbreakable ', and system level since the administrator is the
only one to have the power to modify the configuration of the machines.
Reliability: AbsoluteBoot guarantees a reliable and invulnerable
Optimisation: AbsoluteBoot enables you to install recent
OS versions and applications on first-generation computers, thus optimising
the performances of your existing PC park.
Flexibility: AbsoluteBoot offers the unique possibility
to start Windows NT or 2000 from any boot media: CD ROM, CompactFlash
card, network server or hard drive. This flexibility is due in particular
to the considerable reduction of the size of the image compared to the
size of the original system (an AbsoluteBoot image comprising
Windows NT and IE weighs only 32Mb).
Maintenance: AbsoluteBoot facilitates the task of the administrators
responsible for the installation and the maintenance of a computer park
by 'simplifying' the machines. Indeed, the machines function from an
image of the configuration; in case of false manipulation or an awkward
installation of the user, or should the least system breakdown occur,
the user only has to switch off and re-boot the machine to instantaneously
find the original clean configuration.
Costs Reduction: AbsoluteBoot generates a significant fall
(between 30 and 60%) of the Total Cost of Ownership (TCO)
by the significant reduction of support and maintenance requests: elimination
of help-desk calls, elimination of maintenance interventions, total
availability of the systems and applications critical to the good operation
of the company, maximum productivity, etc.

Execute Windows NT4.0 or 2000 from a local CompactFlash card.
Indeed, the Spy tool allows to withdraw any unnecessary file or program
from the operating system. An AbsoluteBoot image including Windows
NT4 and IE weighs only 32Mb.
Operation of AbsoluteBoot
The administrator creates a reference PC, on which Windows NT or 2000
and the desired applications are installed and parameterised, and installs
AbsoluteBoot. The latter generates a compressed image of the configuration
according to parameters fixed by the administrator. This image, which
can be of a very reduced size compared to the real size of NT or 2000,
is then transferred on the selected medium (CD, hard disk, Flash card
or boot server), and the target machine is ready to start with the 'OS'
AbsoluteBoot and AbsoluteBoot 2000 comprise 2 applicative
Wimagen: the files generator Wimagen creates the image(s)
from the selected files, and compresses the image. The image file is
then transferred on the selected media, and the target machine is ready
to boot from the image.
Pattern Editor: user interface dedicated to editing the image models
in order to not be limited to the only examples provided in AbsoluteBoot.
These applicative tools use notably the following programs:
MarDev: at the heart of VMA architecture, this 32 bits driver
makes it possible to execute the image in RAM memory.
Spy: once the reference machine is set by the administrator, the
latter starts the Spy program. Spy literally 'spies' the
system to detect the files really necessary for the execution of the
chosen applications and selects them, leaving aside those which are
not necessary in order to generate an even smaller image.
Pagemas: in order gain space in RAM memory, AbsoluteBoot
can off-set a major part of the volatile area used towards a file (Pagemas)
on the hard disk. This solution makes it possible moreover to use a
far more important memory capacity.
Conditions of implementation
Have a valid Windows NT or Windows 2000 licence(s)
Have a sufficient knowledge of the installation and maintenance procedures
of Windows NT or Windows 2000.
Format the hard drive of the 'reference' (source) system in FAT16.
Client computers can be either PCs, Network Computers (NC) or NetPCs
that have an INTEL x86 (Pentium recommended) processor and a minimum
of 32 Mb of memory.
Client computers must have the possibility to choose the boot sequence
(CD-ROM and/or network) and have either a network card or a CD-ROM drive.
