David Broughton pictured at the “What DOS Can Do For Windows Users” talk at the Riverside Centre
Denny Linzmaier once again showed his skills and flair in
Computer Technology by showing how to couple up two monitors
using an extra PCI graphics card with 32MB RAM in a Dell desktop
computer. To illustrate to our members present at the meeting,
Denny implemented two projectors, instead of using two monitors to
enlarge the demonstrations. After changing the settings in the
Display Properties to get the correct resolutions on both monitors,
Denny showed how to drag and drop files from the one screen to the
other. Denny had on hand a Belkin 2 port switch box, which enables
two computers to work together. Hitting the scroll lock on the
keyboard enabled Denny to use the arrow keys to move a file from
the one screen to the other.
After the coffee break, Denny then discussed the linking of the two
computers by means of network cards and cable and then ran a piece
of useful software called WinVNC. The VNC viewer was installed
on the second computer, which then enabled the one computer to
control the second computer and we saw that the mouse ran on both
computers. Thanks Denny for your very interesting presentation.

A family consists of Mum, Dad and the three children, Gerald, Fred and
Gerald is four times older than Angela. He is also the sum of Fred's and Angela's ages. And if
Gerald's age is added to Mum's, you get Dad's age. Dad is nine times older than Fred. All the
family's ages added together come to 58 years. (For the sake of the problem, we assume they
all have a birthday on the same date so that their ages are all whole numbers of years.) What
are the ages of each member of the family?

This puzzle was to draw a diagram with E (the number of edges) = 15; V (the number of
vertices) = 10 and F (the number of faces) = 7. Only three edges were permitted at each
vertice. I was also interested in how many different diagrams could be produced with these
constraints. By "different", of course, I mean different topologically. I found 6 which are
shown above. Peter Greenhalgh, Ray Boote, Rosemary West and Bill Woodmore sent in
diagram D1, the double pentagon. Gordon Stonham and John Bownas found D2. Les
Burridge sent in the interesting D4b which he described as a tetrahedron with the top vertice
chamfered off on three edges. At first I thought this was a new form but later realised it was
topologically equivalent to my own D4a. It is an interesting exercise to check that this is so.
Notice that D4a is a cube with a corner cut off. John Moxon sent in D6. All the diagrams have
been redrawn by me (using Paint) so that all polygon faces have internal angles not exceeding
180 degrees with the external face having angles not less than 180 degrees. If anyone can find
a new diagram that is not topologically equivalent to one of the six above, I shall be very
interested. The numbers in each polygon, plus the external face, are the number of sides for
each polygon and their total must be 30. This was one way of checking the validity of the
answers. Can you prove that this is a sufficient check?
Many thanks to the eight members who sent in answers to this interesting and novel puzzle.
As usual, one was chosen at random for the £5 book token and this was won by John Bownas.
Congratulations to all eight and thank you for your answers.

Browsing through a mail order catalogue from Simply Computer, which is
delivered to my door on a regular basis, it never ceases to amaze me as to the
huge range of hardware available on the market. What do they do with all the
items that are unsold? As the editorial section of Computer Shopper Magazine
says “if you hear PC buyers complaining about choice, it’s usually because
there’s too much. The sheer number of products on offer can be bewildering”.
Computer Shopper Magazine went on to say, because you can buy your
favourite artist’s music from only one record label, you’re forced to pay
whatever they dictate 60 minutes is worth and let’s not forget that prices went up when the world
switched from vinyl to CD, despite the fact that CD’s are cheaper to manufacture and distribute”.
Maybe if the price of this vast wealth of material was reduced to a more realistic level, more
products would be purchased by consumers. Some of the best selling hardware can be seen on
pages 8 and 9 of this journal.
Do you find that follow up support for items of hardware leaves a lot to be desired? “After sales
support is considered to be the Cinderella of the consumer PC Business, sidelined by suppliers
focussed on building bigger, faster and evermore powerful computers” so says the PC Magazine
editorial and I definitely agree with this view. The manufacturers say that their hardware profit
margins are slim but surely the average home user doesn’t want all the sophistication that the
manufacturers are serving up. The home user and possibly the business sector desire a capable
computer that operates in a simple but efficient way without all the bel ls and whistles. A good
example of lavish products is a Midi Tower that I have recently purchased through mail order,
which contains a Cold Cathode Fluorescent Lamp with Voice Control. I don’t know how this
works because this extra in my case has failed to operate. On contacting the suppliers, the reply
to my need of a replacement was met with “send the whole case back” but what about the cost of
the transportation? The cost of sending the case in the first place cost £18 by courier and then
there is the cost of postage to return the case and another £18 to send a replacement case. This
doesn’t add up in my book as a paying customer. From a marketing point of view shouldn’t some
consideration have been given by the manufacturer, namely Q-Tec, to keep spare parts so that in
the event of a failure the item that is giving a problem could be replaced without the shipment of
the entire case?

The road to data recovery
Tools such as SystemWorks and SystemSuite
can help you work out where problems are
occurring on your PC, and they even provide
unerase tools that can help recover files that
have been deleted accidentally.
When recovering lost data, there are a
number of options open to most users. In the
first instance, a Windows crash may have
made your system unstable – what is less
important here than the issue of your data
going missing is the fact that your PC is
becoming unworkable.
Windows Me and XP have built-in System
Restore tools that you can access from the
Programs, Accessories, System Tools menu,
returning Windows to a previous, more stable
For users of earlier versions of Windows,
GoBack from Roxio provides a similar
service. If you have lost important data, as
mentioned previously, utility suites from
McAfee, Ontrack and Symantec include tools
for unerasing data, while Ontrack also
provides a more robust data recovery
application, EasyRecovery Professional,
which performs similar diagnostics tests to
SystemSuite but also offers a host of tools for
retrieving data from your system.
Such tools are not always sufficient,
however. Installing them after you have
experienced data loss is likely to do more
harm than good. This is because when data is
deleted the operating system does not actually
remove it, it simply gets rid of the file headers
that point to where the data is on disk.
Installing more files will subsequently
overwrite that data, making it unrecoverable.
Such tools are also less useful when a disk
has suffered some form of physical damage.
But even if you do not have data recovery
software installed or your drive is harmed in
some way, you may still be able to retrieve
information via a data recovery service, such
as Vogon:(,
MJM Data Recovery:( or
Ontrack:- (
Ontrack, which first supplied its Disk
Manager in 1985 and began data recovery
services in 1987, is the best known of these
companies. It offers data recovery both in the
lab and remotely over the net.
In either case the first service provided is an
estimate of the projected time and cost of
retrieval. “The time it takes to get data back is
critical,” points out Ontrack Europe’s Todd
Johnson. “With remote data recovery we can
get the customer up and running in a couple of
When using a firm such as Ontrack for data
recovery, the disk is first diagnosed, either
remotely by sending it to the company, or by a
visit to your home or office from a technician.
Some companies offer free diagnosis, but this
will probably be recouped at a later date. In
any event, be prepared to pay. As Ontrack’s
Johnson remarks, “You only have one chance
to get back your data.”
Prevention is better than cure
. “There are plenty of people who wish to
attack you and run malicious code on your
PC. To prevent a computer being
compromised, we always advise people to
implement safe computing, which means both
using the right software and maintaining a
certain way of thinking,” says Symantec’s
André Post.
For Post, antivirus software is “supermandatory” on any system. “It’s the core of
safe computing practices,” he says. “Why do I
think that? We see many viruses that are so
poorly written that, in many cases, they do not
simply infect files but destroy the host. If that
happens, the chances are that you won’t be
able to recover all your data if you try to clean
a virus after the event.”

Bios data; alternatively, a poorly configured
machine could go down, corrupting
information that points to the files on your disk.
But CD-Rs are not without their problems.
Because data is burnt rather than stamped into
the recording layer, apparently indestructible
CDs can deteriorate fairly rapidly and even the
best are rarely guaranteed for more than 10
In addition, the 650-700MB limit of CDs
makes them unsuitable for backing up today’s
multi-gigabyte hard drives. Writable DVDs are
becoming more popular, but backup is one area
where tape comes into its own. Tape can, in the
right conditions, have a shelf life of up to 30
years. Though slow, drives such as the
Seagate TapeStor ( or
HP Surestorecan (
accommodate up to 40GB of data – more than
enough room for a complete backup.
Increasingly popular, however, are drive
alternatives: fixed or removable, internal or
external. At its cheapest, this can be no more
than a second hard drive - copy your data from
C to D and you will have one of the fastest and
most reliable backup options on the market. If
anything happens to the first disk, you can
simply switch to the alternative.
External drives are another option. Iomega,
famous for its Zip Disk has recently released
the Peerless cartridge drive with capacities of
10-20GB (
Firewire or USB drives are even better priced
alternatives, offering capacities of anything up
to 160GB. Like the Peerless system, external
drives also have the advantage that they and
your data can easily be taken off site.
Crash team
True hard drive crashes, where the drive
mechanism fails – for example, when the read/
write head collides with a platter – are
fortunately very rare, but there are plenty of
other reasons why you may not be able to
access your data. A virus, for example, could
delete files or, more seriously, wipe essential
Such events need not be entirely catastrophic,
but you do need to prepare for them in advance.
First and foremost, you need to prepare a
recovery disk. This consists of a set of strippeddown MS-DOS drivers that enable you to boot
your PC from the A drive. You can create such
disks in Windows 9x and Me via the Recovery
Disk tab in Add/Remove Programs, or by
booting from your Windows XP CD and using
the Recovery Console by typing D:/i386/
winnt32.exe /cmdcons, where D is the letter of
your CD drive.
A startup disk or Recovery Console provides
a few basic command tools to diagnose and
repair your system. Typing Chkdsk /f, for
example, checks the status of a disk and can
repair some errors, while Fixboot writes a new
partition boot sector to your disk and Expand
extracts a file – useful if you need to replace a
device driver, for example, from your Windows
disk. These are powerful tools, but also
difficult to use, and it is no surprise that a
number of simpler safety net utilities have
developed, such as Ontrack’s Fix-It Utilities
(also available as part of SystemSuite 4.0):
McAfee Utilities 4.0:
and Norton Utilities 2003 (included in
Symantec’s SystemWorks 2003)
These programs all work in a similar fashion,
and include most of the tools you will ever
need to protect and optimise your PC –
SystemWorks and SystemSuite in particular –
including antivirus and even firewall protection
as well as diagnostics and repair tools.
If you have SystemWorks or SystemSuite
installed, each program offers a one-stop
solution for beginners that will analyze and fix
most faults on a system. If you require a more
detailed repair, both also offer expert tools,
such as Norton Disk Doctor and
PCDiagnostics, and DiskFixer as part of

Ta l k on DOS, 4 t h June
Trouble-free computing
David Broughton stepped in at short notice for the first Wednesday meeting to deliver a talk
with the title "What DOS Can Do For Windows Users", originally scheduled for 2nd July. He
started with a short PowerPoint presentation that answered the question "What is DOS?" in
two ways. The first answer was that DOS (for Windows users) is like a stethoscope for
finding out what is really going on inside the computer as opposed to the gloss and spin that
users are presented with when using Windows.
The second answer was more prosaic: DOS was the original operating system for the first
IBM-PC brought out in 1980. It works by the user typing commands on a command line and
pressing Enter. Whilst primitive in operation, DOS has been gradually improved by Microsoft
over the different generations of Windows with the latest version that comes with Windows
XP being a considerable improvement over older versions. Help in using DOS commands can
be found by typing "/?" after the command where a summary of the command's operation can
be found with any of the extra enhancements. For example, the XCOPY command now
features an optional exclusion list. This is a text file of directories that are to be excluded from
the copy operation, useful when using XCOPY for backup operations.
REM File: BU.BAT, 2003-06-02

Isabel Robertson, a freelance writer who lives
on one of the islands of the Inner Hebrides,
thought. Having spent days researching and
writing an article for a key client, four hours
before the deadline she tried to open the file
from a floppy disk to send it by email. Her
computer refused to read the drive.
After trying a number of basic steps, it
became obvious that there were serious
problems and she was in danger of losing her
client. Because of the deadline, as well as the
fact that she was a day’s travel from the
nearest centre that could help her, Robertson
used the internet to find an emergency service
that could help. She accessed the remote data
recovery service offered by Ontrack and was
able to save her files – and her contract.
“Without Ontrack’s help I would have let the
client down badly. The Ontrack engineer was
brilliant and I was so impressed that I could
retrieve the data without leaving the house. I
would recommend the remote data recovery
service to anyone,” she said.
should also be complemented with regular
checkups that include virus protection”.
For André Post, senior researcher at
Symantec Security Response, it is all about
safe computing, which is not just software but
a way of thinking: “Make sure you have
antivirus software installed and kept up to
date, and preferably a firewall as well. Also,
keep all your software patched with the latest
security fixes to keep your system as safe as
possible. Last, but not least, use common
sense – for example, when receiving emails
from sources you don’t know.”
When is data disaster most likely to strike?
Most common are those incidents where, after
upgrading a piece of hardware or installing
new software, a conflict occurs and a carefully
balanced house of cards comes tumbling
down. Many people will perform a major
operation, such as changing to a new operating
system, without checking their backup systems
only to find that a vital piece of hardware or
software, such as a tape drive or backup
application, no longer works.
Computer rehab
The most important step for recovering from a
computer crash is to ensure that you have
backups of all your important data and
Disks and images
An alternative to this type of backup software
is to use disk imaging programs such as
Norton Ghost 2003 or PowerQuest’s Drive
Image ( These
applications create a compressed image of
your drive that stores all application, user and
system files and can be copied to CD. Should
your computer fail, simply boot from your
drive image to restore your system as it was
Your data lifeline
According to Todd Johnson, general manager before the crash.
Hardware options are more varied; Probably
at Ontrack Europe: “Protecting information is
the most common form of backup, now that
not just about restoring data in the event of a
crash, but also ensuring that you have plans in the humble floppy has had its day, is the CD:
place to keep it safe. Central to this is having a cheap enough and, with the latest CD-writers,
fast enough not to deter even the most
proper procedure for backup, but the sort of
surgery required for full recovery of your PC recalcitrant data savers.

by David Broughton
After the short PowerPoint presentation, David demonstrated various DOS commands and
how they can be used within Windows. In WinXP, the old Win 95/98 MS-DOS prompt
icon is replaced with a Command Prompt icon (see top of page 6) which can be found in the
Accessories area. You can drag these on to your desktop. The new Command Prompt in
WinXP provides for a large buffer to hold text that previously disappeared off the top of the
screen. A scroll bar is now provided to bring back the vanished data into the DOS window.
The End key gets you back to the flashing cursor on the command line.
The Win95/98 set of icons along the top of the DOS window are replaced in the WinXP
version with a menu that can be invoked with a right mouse click on the title bar.
Born in 1934, David spent his childhood in a small mining village in Yorkshire. After leaving
school at age 14 he had an assortment of jobs from ophthalmic lens setting to the chemical
analysis of metals before entering the RAF where he spent the first 9 months learning about
electronics full time. This was a great career booster. On Leaving the RAF in 1957 he joined the
BBC as a technical assistant and rose, after 20 years and lots of part-time education, to the status
of an Electronics Design Engineer. On the introduction of computers at the BBC in 1962 David
took a course in programming the Elliot 803 computer and got hooked on programming. The
Elliot 803 weighed 594 kg without any peripherals and consumed 3.5 kW of power.
To learn more about computing David took a part-time degree course at London University to
obtain an M.Sc. in Computer Science, gaining professional membership of the British Computer
Society. He then set up a new section in BBC Engineering Designs Department providing a
scientific computing service to electronic design engineers.
When home computers became affordable in 1978, David purchased a North Star Z80 computer
running at 4 MHz for £2,500 (with a massive 32 Kbytes of memory!) and programmed it to play
chess. This was a very advanced machine at the time. Communication was via the RS-232 serial
port for keyboard input and display monitor output and it had a primitive disk operating system
predating even CP/M. The floppy disks could store 180 Kbytes of data. The chess program was
entered in the Computer Chess Competition at the Personal Computer World Show in September
1979, winning the top prize for an amateur entry of £1,500 which partly paid for the computer.
In 1980 David left the BBC to become a self-employed programmer and consultant, starting with
chess machines for the commercial market. In 1981 his program won the World Microcomputer
Chess Championship with the SciSys Mark V chess computer. He later worked for a company
producing specialised video effects machines for the television broadcasting industry. These
required complex mathematical equations to be solved in real time using very fast
microprocessors. You often see the results when your TV picture rotates and zooms off into the
distance, and similar effects.
David moved to the Isle of Wight in 1987 with his wife Dina and joined the Computer Club
shortly afterwards where he started the Hot Key journal as Editor in 1991. He has also been
Treasurer, Secretary, Membership Secretary, Vice-Chairman, Database Manager and
Webmaster. His hobbies are inventing puzzles for the Hot Key magazine, chess, astronomy,
table tennis, walking and cycling. He is a confirmed atheist and a member of The Isle of Wight
Humanist Group who try to spread the message that this life is the only one we have so live it to
the full.
What DOS can provide for the Windows user is the ability to find out what is going on
behind the scenes in terms of directory tree structure (which Windows Explorer confuses by
showing several items that reside on the C hard disk as existing nearer the root of the tree).
The use of wildcards in file specifications is useful for seeing subsets of directories or for
operations on subsets of files. One of the most useful features, however, is the use of batch
files where a sequence of DOS commands can be executed by typing one command or
double clicking a desktop icon. Extra commands like "IF" with Go To labels allow for
conditional execution in batch files. The WinXP version also provides an "ELSE" clause,
which brings structure into the language.
David demonstrated how to run a DOS program either from the command line or from a
desktop icon. The Program Information File (PIF file) that can be created for this purpose
provides features that allow each DOS program to run in its own environment with
individually tailored AUTOEXEC.BAT and CONFIG.SYS files for each one (they are
called AUTOEXEC.NT and CONFIG.NT in the WinXP version). These batch files will be
run before the DOS program starts in order to set up drivers and environment variables
needed by the program. And of course, more than one DOS program can be run at the same
time and with other Windows applications. It is also possible to set up a PIF file that will
run a batch file in its own right without any program. The PIF file can be viewed and edited
by right clicking the icon for the program and selecting "Properties". If there isn't one, a
default PIF file will be created. PIF files are not obligatory: DOS executable program files
can be dragged on to the desktop and run from there using a default PIF. The best way to
create a new PIF file is to amend a copy of an existing one by dragging with the right m ouse
button and selecting Copy from the menu.
When a DOS program ends, sometimes there may be important information left on the
screen. To avoid missing this, you have to untick the "Close on Exit" box in the PIF file
under the "Program" tag. This will leave an inactive window containing the text screen
produced by the program.
A simple DOS batch file for backing up frequently used documents was shown and
explained in some detail. This is reproduced opposite. It assumes that the D: drive is a CD
for use as the backup medium. It can only be used with the WinXP version of XCOPY.
With a few extra utility programs that David had written for himself, much can be done in
DOS that, in Windows, is either impossible or very awkward. Some of the most useful a re
programs that find files and folders, whether Hidden or System, anywhere on the hard disk,
optionally within a date window. David said he would make some of these available on the
club's web site. You can e-mail David with questions on DOS via the Yahoo e-group
"iwpcusers" or to David directly (see page 3 for e-mail address).
