PC Troubleshooting Project

Stop Code: PROCESS1 INITIALIZATION FAILED

As a result of a PC replacement and upgrade project for Action for Asperger’s, we were presented with a seemingly serviceable Dell Optiplex 755 machine but suffering from a critical failure on power-up, meaning that the computer was unable to boot into windows, preventing use and severely limiting the diagnostics and configuration options.

PC restart

The first step following a reboot was an automatic ‘startup repair’, however, this didn’t result in a fix:

Startup Repair

Rebooting again and selecting F2 during the initial boot-up screen:

Boot Up

enabled a look at the system information, which indicated that the PC hardware was fine.

System info
Processor info
Memory info

As an extra measure, the internals of the computer were briefly examined, ‘reseating’ components including the video board, memory chips and hard disk and then the system test run to verify all was well.

Internal
Test

It was concluded therefore that the PC hardware was not the cause of the difficulties, and that the Windows installation was severely compromised. 

From the bootup, troubleshooting was selected

Choose an option

From the ‘advanced options’, the Command Prompt was accessed.

Advanced options

Using these commands:

DISKPART

SEL DISK 0

LIST VOL

It was possible to view and confirm the drives and their assigned letters.

Diskpart

Extra information was provided using this command:

wmic logicaldisk list brief

Progress was further hampered by the internal DVD/CD drive not being recognised on boot-up, in its place an external DVD drive was connected.

Rebooting and pressing F12 on power up enabled the adjustment of the Boot priority, selecting the DVD drive first.

A copy of the Boot Repair Tool by yannubuntu was next downloaded and a boot-repair-disk created

This was run from boot and gave encouraging results:

Boot Repair Disk

Alas, these steps hadn’t cured the problems, now a further critical error message was displayed:

Recovery

Consequently, using the Microsoft USB/DVD Download Tool, a Windows 10 install disk was created (confusingly the site specifies Windows 7, but it works fine for Windows 10)

This was booted and the appropriate selections made for a fresh installation of Windows 10:

Windows Setup
Windows Install now
Windows type of installation
Windows operating system selection
Activate Windows
Applicable notices and licence terms
Partition choice

At this point, it was found necessary to delete the old windows partition, extend a different partition and create a new partition in order to be able to commence the windows installation.

Partition selection

It did however then allow the installation of Windows onto the other partition, meaning that two bootable volumes were created. Might be useful for future upgrades or troubleshooting.

Choose OS

Just the straightforward matter left of completing the user configuration of the operating system ready for use. 

Choose region

All done, pleasing to conclude that the critical issues with this PC could be resolved through software corrections alone!

Nokia ‘Dynanet’ Telecoms – Stock disposal

Nokia Dynanet

‘Last chance’ for spares!

The Nokia ‘Dynanet’ family of PDH Transmission telecoms products has served customers well for the last 20+ years, and indeed some networks continue providing good operational service. 

DM2
Dynanet Subtrack

@YellowsBestLtd has supported requirements to maintain these networks by supplying various spare part items from refurbished and surplus stocks in perfectly working order.

However, demand has recently reduced and warehouse space is needed, so now the time has come to recycle / dispose of a large proportion of the remaining equipment. Consequently, there remains a short-term opportunity to obtain any items still required to maintain existing deployed infrastructure, before the products are gone.

Here is a stock list of the main items currently available, though there may be a few additional parts that can be supplied. Hence, please check and if you do have any requirements, please let us know – before it’s too late! We look forward to hearing from you.

Solar energy project

Solar Energy Project

“Off-grid eCharger”

The aim of this ‘off-grid’ solar energy project was to build a charger for an eBike so that its battery could be charged (when not in use) from power collected from the sun via a ‘fixed’ off-grid installation, rather than relying on mains energy. This can also be used for other battery charging and small backup supply purposes.

Four main elements were put together to create the solar charging ‘system’:

SolarPorjectElements

Solar Panel

This fundamental part performs the key task of converting sunlight into electrical energy. There is a wide range of panel types to choose between. Firstly, sizes include the very small, through 50W, 60W, 80W and up to 100W. Thereafter, systems are typically built from connecting multiple panels together.

Solar Panel

50W Mono Flexi Solar Panel

Then, there are four main types of solar array:

a) Poly Crystalline – cheaper to manufacture, sensitive to high temperature, less efficient with a shorter lifespan
b) Mono Crystalline – more expensive, more efficient, with a longer lifespanc)
c) Thin-Film Amorphous (A-Si) – flexible, lower cost – easier to produce, shorter lifespan, lower power
d) Concentrated PV Cell (CVP) – very high performance, solar tracking and cooling required, very expensive.

Finally, there is the choice of construction type:

i) Rigid – cheapest and most solid, heavy and longest lasting
ii) Flexible – PET – light-weight and bendy, ideal for vehicles and temporary installations
iii) Flexible – ETFE – longer lasting, marine grade, can be walked on.

For this project, the aim was to use something lightweight that could be easily attached to an existing small building structure by means of the re-enforced ringlets in its corners (not all panels have these, so choosing had to be careful), rather than a permanent roof-top installation, and so the Flexible PET type was indicated.

After some consideration of likely ‘sun-hours’ – estimates tend to indicate an average of 2-3, depending on the season and weather – and also cost, a 50W 12V Mono Crystalline Flexible PET panel was selected. This size could prove to be an under-estimation for the task, but this can be supplemented later as necessary since its possible to join panels in parallel to increase current (or series, to increase voltage). That will require ‘T’ or ‘Y’ joining pieces for the MC-4 solar cable connectors, and potentially in-line fuses to protect separate ‘strings’ of connected panels (on their own they don’t need the fuses since their short-circuit current rating is sufficient).

If a panel becomes partly shaded, its whole output diminishes. Hence the advantage of having separate panels is that they may contribute more energy individually that using one large single panel. Another aspect is that it is likely that the cost of solar panels will reduce over time, and so adding to the system over time makes sense, rather than trying to ‘future proof’ the power requirement.

;

Charge Controller

The task performed by this element is to ‘condition’ the output of the solar capture, converting an unregulated supply of around 18V (for a single panel) to a more stable 12V, the energy from which can be directly used or stored in the battery. The use of a controller avoids the risk of over-charging of the battery or issues with varying power, and will shut off its output to the loads when the supply is diminished and the battery is discharged. There are many models, which vary in power rating and functionality, some with simple LED displays and others showing a range of information, and may include sense terminals for long cable runs, temperature measurement for adjustment due to the weather and equalisation functionality for spreading charge across multi-battery systems.

PWM Charge Controller

PWM Charge Controller

The controllers fall into two main types:

a) PWM – Pulse Width Modulation

b) MPPT – Maximum Power Point Tracking

The latter of these is much more efficient, likely to convert more of the captured solar energy into stored power. However, these tend to be at least 3 times more expensive, often much more.

A modestly–priced (reasonably-functioned) PWM unit was selected for this system, with a 20A rating (more than enough for the initial project requirements). The reasoning for this product selection is this: with a small system, should the captured energy be not enough, then purchasing additional panel(s) to increased the wattage is more cost-effective in terms of energy produced, compared with the gain from the more efficient controller. It only becomes worth purchasing the MPPT version when much more energy is being generated (and therefore ’lost’ with a less efficient charge controller).The controller model selected is capable of both 12V and 24V operation, which allows for the increase the voltage rating of the system if desired in the future.

;

Battery

The traditional choice for this type of storage application is the ‘Lead-Acid Cell’, though it needs to be of a Deep-Cycle ‘Leisure’ variety, which is intended to be frequently discharged and recharged, rather than the ‘starting’ classification which is used in a vehicle for short-bursts of energy to get a motor running, after which its mainly in stand-by and therefore expected to be 100% charged most of the time.

AGM Battery

AGM Battery

Apart from this distinction, there are two main types of product:

a) ‘Flooded’ Wet-Cell or Valve Regulated Lead-Acid (VRLA)

b) Absorbed Glass Mat (AGM) or Gelled Electrolyte (Gel)

Of these, the Wet-Cell traditionally required periodic ‘maintenance’, topping up with fluid, though VRLA sealed versions are now available, and tend to ‘vent’ gas and can’t be tipped over due to the fluid inside. The AGM and Gel types however are available maintenance-free, don’t ‘vent’ gases and don’t have fluid that can spill out.

The AGM-type was selected for this project as, whilst being a bit more expensive, offered the convenience of a product shouldn’t require special attention; these are less sensitive to over-charging and can stand for 30 days totally discharged without harm.

There are a number of measurements of the capacity and capability of batteries:

  • Reserve Capacity (RC) is how long the battery can deliver a constant current of 25A at 80F
  • AmpHour (AH / C20) represents how much charge is stored. It is the energy delivered continuously in 20 hours at 80F without falling below 10.5V
  • Cold Cranking Amps (CCA) is a measure of the ability to start an engine cold. It is the number of Amps delivered at 0F for 30sec by a 12V battery whilst maintaining at least 7.2 Volts

A capacity of 110AmH was chosen for this project.  Whilst ‘the more the merrier’ in terms of storage is certainly the case, this capacity should be sufficient for the basic storage needs.  It is advisable however to allow for discharge of only 50% of the stated rating, whilst also bearing in mind the possibility of a few days without sun.

It is possible to add batteries in Parallel to create more storage, or in Series to increase the voltage of the system. For a modest system set-up, 12V is sufficient and convenient for the purpose. Adding another battery to double the system voltage to 24V would have a side-benefit of requiring lower gauge of wiring.

;

Inverter

In order to convert the 12V DC power generated from the Solar Panel and stored in the battery, to the 240V AC required by the Load, the Li-Ion battery charger adapter, an inverter is needed. This wouldn’t be the case if a suitable 12V charger-adapter could be sourced, which would avoid the inefficient ‘double-conversion’ of 12V DC into 240V AC and back into 42V DC again. The inverter does however provide the flexibility for powering other equipment requiring an AC ‘mains’ supply and therefore is ideal for a range of charging and backup tasks.

PSW Inverter

PSW Inverter

Apart from the selecting the correct voltage, which is normally either 12V or 24V (12V required to fit with this system set-up), there are two main choices:

a) Modified Sine-Wave

b) Pure Sine-Wave

The first type is the low-cost product, and available in a wide range of power-ratings, so if high-power is required then that tends to be the preferred choice. The draw-back is that it is less-efficient, creating a ‘blocky’ AC waveform which can upset sensitive equipment. The second type produces a smooth sinusoidal AC waveform equivalent to the standard AC ‘mains’ supply, and therefore is suitable for all equipment types, though at higher cost and usually lower-power rating.

Given the performance uncertainty and potential for harm to some equipment that the MSW product might bring, and the modest power needed, it seemed sensible to select the PSW variant. A 300W product was chosen, partly limited by cost, but also since it is recommended to ‘match’ the power rating to the consumption requirements; in practice the inverter size should be around 3-7 times the power needed by the load appliance. A much higher-than needed inverter is ultimately less efficient for smaller loads, consuming more power than necessary.

.

Additional parts required were cabling and mounting accessories, plus some optional ‘add-ons’ in the form of other battery chargers and lights to make full use of the generated power:

System accessories

Accessories

Accessories – MC-4 Connectors & Cable, Light, Battery Charger, Fuses and holder

  • An extension cable to connect the solar panel to the solar controller. The panel itself comes with about 1m of ‘tails’, fitted with MC-4 connectors which are standard for solar equipment. A ‘male’ connector provides the positive supply, and a ‘female’ connector offers the return negative connection. Two cables are therefore required, with the appropriate MC-4 connectors at one end, and unterminated at the other to connect to the solar controller. A ‘top tip’ is to obtain a single fully-terminated extension cable of twice the required length, and cut the cable half-way. For this project, a 25m extension cable was sourced, which provided 12.5m as a sufficient length for both positive and negative connections once cut in half. Thickness of the cable is an important consideration, so that the rating is sufficient for the power of the system and the loss due to the length of the connection. For this installation, a 4mm2 (12AWG) cable was selected, suitable for up to around 15m and 23A, meeting the needs.
  • Battery terminal leads
  • Midi and Blade Fuses and holders for fusing of the output from the battery supply (40A) and protecting the input to the charger controller (15A). The inverter came with a 35A mini-blade input fuse.
  • Lugs and wire for the Solar supply and DC power connections
  • Fixing screws for the solar panel, and cable clips
  • 12V Lamp with remote and motion sensor, providing a light powered by the solar energy for the indoor work area
  • AA / AAA / C / D / PP3 battery charger, for supplementary battery charging requirements, fed from the 12V output from the charge controller (avoiding unnecessary 240V conversion)

The resultant assembly captures energy from the sun via the solar panel, ‘conditioned’ by the controller (to avoid over-charging or issues with varying power) and stored in the battery. Naturally, this can take place throughout the day when the sun shines, without the need for a load to be present. Then when required, the load can be supplied from the stored energy.

The inverter is utilised to supply a replacement AC feed to the specialised Li-ion charger required for the load battery, which can therefore be used as an ‘off-grid’ power source for other uses in place of a regular ‘mains’ supply.

Charging additional Li-ion or Ni-Cad batteries for other equipment can be also be facilitated using the 12V output to supply an appropriate battery charger, and as well as powering 12V LED lights for illumination of the work space.

Hopefully this project is of interest and of use to anyone contemplating establishing a solar energy system, with the aim of harvesting energy from the sun, a ‘free’ resource available to us all!

Legacy Computing – Windows through time

windowsthroughtime

DOS Beginnings – the early days of ‘personal computing’

The ‘Personal Computer’ (PC) launched by IBM in 1981 was a breakthrough that revolutionised the workplace, though the early ones were quite limited especially in terms of how to use them and what they displayed. Not only did they have no ‘touch screens’ for ‘swiping’ and ‘apps’ as we know them now, but there was no ‘graphical user interface’ either. Rather than a ‘desktop’ with icons and a mouse pointer, there was just a black screen with text and a flashing cursor.

DOSscreen

DOS

This was Microsoft DOS (Disk Operating System), which seemed to be the ‘proper’ way to use computers for at least a decade.

GEM - Atari ST

GEM – Atari ST

Indeed, some PC users were initially ‘suspicious’ of icons and windows which had appeared on the Apple Mac as well as other alternatives in use like GEM on the Atari ST.

People had become so used to typing commands, and knew all the ‘switches’ and other modifiers e.g. DIR /W to display a list of the files across the screen rather than in a column. And ‘WP’ was all you needed to get ‘Word Perfect’ to launch – the then favoured Word Processor, which gave rise to some still familiar short-cuts like ‘Control-C’ to copy.

Desktop computing takes-off and ‘Windows’ takes-over

Windows 3.1

Windows 3.1

Windows 3.1 showed PC users something different from around 1992, when 386 and 486 PCs powerful enough to run it well became available.

mouse tutorial

mouse tutorial

It even came with a tutorial to show users how to use a mouse!

Windows 3.1 floppy disks

Windows 3.1 floppy disks

No-one enjoyed having to install it using 7 floppy disks though.

And at first it seemed somewhat unnecessary to run existing applications.

Win95-DOSprompt

Windows 95 – DOS prompt

Indeed, there was a bit of an ‘outcry’  that Windows 95 and later variants didn’t first boot into DOS!

But then it was realised there were some key benefits. Now you could delete a whole directory in one go without having to clear out each ‘level’ – not always the safest feature! Email really became more useable when you didn’t have to log in specifically to check to see if you had messages; now it could be running all the time in its own window.

The rise of the Internet – and security issues

Win98Desktop

Windows 98 ‘desktop’

With each variant of ‘Windows’ came more sophistication, and suddenly a whole world of connected information could be accessed with Netscape and then Internet Explorer, which then meant Windows really became a ‘must have’.

Internet Explorer - WinXP

Internet Explorer – Windows XP

Certain difficulties were experienced getting old and new applications to behave themselves in the Windows environment; stability and also backwards compatibility started to become issues. Users now had to deal with ‘blue screen’ crashes of Windows, and then a variety of increasing security threats and viruses requiring ever-more enhanced anti-malware protection applications and mandatory backups.

The continuing need for ‘Legacy’ support

Although the majority of modern offices, educational establishments and homes now use the latest PC hardware as well as phone and tablet computing devices running the newest generation of operating software and applications, some industrial workplaces have professional implementations of systems that still make use of early computing platforms (ranging from desktop PCs to OSS servers), where the basic requirements are unchanged, and particularly in stand-alone use where security threats aren’t an issue. And some people still have old PC games to play!

Drive Setup

Drive Setup

It can however be quite a task to restore the operation of legacy systems, particularly if backups are missing or incomplete.

FDISK for partitioning

FDISK for partitioning

Associated issues include obtaining the appropriate hardware replacement parts such as disks (modern versions can be too high capacity to work well with old systems) requiring the right settings of cylinders, heads and sectors, and preparation using FDISK and FORMAT commands.

Floppy Disk

Floppy Disk

Software ‘patching’ of configurations may be needed, hunting out correct versions of driver files and specifying the right parameters. Creating a floppy disk with ‘boot’ files can also be a helpful tool!

Emulation and Virtualisation

There’s still a way today to run legacy software even without the old PC hardware, and that’s via the ‘joy’ of emulation and virtualisation. Even using an Apple Mac or Linux computer, it’s possible to run various flavours of Windows legacy software.

Particularly useful applications to enable this include:

DOSbox

DOSbox

DOSBox – a handy emulator tool which enables the running of old DOS based applications in an application window. Relatively straight-forward to setup, with the ability to ‘mount’ folders so that files can be imported.

VBoxWin95

VirtualBox-Windows95

VirtualBox – a fully featured virtualisation tool that allows the creation of ‘virtual machines’ into which can be installed a full operating system, such as Windows 3.1, Windows 95 or Windows XP. The tool also emulates CD and Floppy drives for  loading disk images and running legacy applications.

CPU fix for Win95

CPU fix for Win95

Takes a bit of work to set up, preparing a virtual ‘hard disk’, and then installing the operating system. There’s a ‘work-around’ needed to take account of modern processors being ‘too fast’ for the old operating software! Also, to set the display to the necessary resolution and get sound working, special video and audio drivers may need to be installed.

win95app

Or you could try the Windows 95 ‘computer as an’ App created by Felix Rieseberg, which can be downloaded and installed on macOS, Windows and Linux!

Legacy mobile phones

Legacy Mobile Phones

The original ‘smartphone’ – Nokia Communicator

Remember way back in the late 90’s and early 2000s, when Nokia ruled the mobile phone market, they launched the Communicator series. Essentially it was the coming together of a mobile phone and a PDA, joined with a hinge that ‘opened up’ to reveal a full QWERTY keyboard and display screen. Always somewhat big and bulky, it initially was way ahead of anything else, offering phone, text, email and even fax communication.

LegacySmartPhone

Nokia E90 Communicator

The E90 was the last and most feature-packed variant, produced in 2008. More compact and powerful, it featured colour screens inside and out, video and photo cameras with flash, 3G telephony, Bluetooth and WiFi connectivity, together with internet browsing, GPS maps, photos, video and music players, radio, clock, calendar, contacts and a file manager, plus games and the ability to install apps like quick office for document creation and spreadsheeting. In short, it had everything we’ve come to expect in a ‘smartphone’, lacking one key ingredient – a ‘touch’ screen.

Nokia E90

Nokia E90 (closed)

10 years on, it’s a testament to Nokia’s impressive build quality that it looks almost as good as new and still works as well as it did, though of course without the ability to pinch, zoom and swipe, and no ‘app store’. The photo and video quality now looks very basic, as do the limited number of games and apps; but it is possible to load it up with an up-to-date Opera web-browser and Google maps. The music player still works well, using a headset or in speaker mode, as does email and texts – and naturally it can still make telephone calls!

Nokia E90 Communicator

The original ‘smartphone’ – Nokia Communicator

The Nokia phone business itself didn’t fair so well, being eclipsed by the competition and then sold off, as recently well documented in “The rise and Fall of Nokia” (shown previously on BBC4, now on youtube) by Arto Koskinen. However, more recently Nokia phones have made a bit of a comeback, relaunched by HMD Global. Though probably no hope of a new Communicator model?!

Mobile phones for all – Nokia 5110 ‘featurephone’

If you can remember the 20th Century and the dawn of the mobile phone, then the Nokia 5110 maybe familiar. Introduced in 1998, during the period of Nokia’s seemingly unstoppable rise, and helped them become the world’s number one mobile phone producer, which they remained for the next 14 years.

Nokia 5110

‘Featurephone’ for all – Nokia 5110

This was the breakthrough when phones ceased to be ‘bricks’ (though still including an external antenna) and became mass-market devices that everyone could consider carrying, even just as an ‘emergency’ phone. Text messaging was included, though many people at the time couldn’t see what the point of that was: “its easier to just ring someone, isn’t it?” How times have changed! Plus it had a clock, calculator, and a choice of ring tones including the now famous ‘Nokia tune’. And Nokia introduced the world to ‘snake’, heralding in the era of mobile gaming. No app store yet, and ‘touch screens’ and even colour displays were still to come. But you could now choose the colour of the product; they didn’t have to be just black anymore!

'snake' game

The phones themselves were of the solid long-lasting construction that characterised the products of that time from the Finnish manufacturer, perhaps due to the harsh winter environment of home they were built to survive, which is why 20 years later, it still works! Looking back, the surprising thing is that despite its rugged nature, a case was often used, and given the (now, seemingly) impressive talk and standby time, it was quite usual to have a spare battery too. Perhaps that was because they were still seen as an expensive luxury, and given that ‘normal’ desk phones didn’t run out of power, ‘early adopters’ wanted to make sure they could always make use of their investment.

Legacy 'Featurephone'

Much has since changed in the world of mobiles, such that they’re not even used much as just ‘phones’, and Nokia’s phone business itself came and went, though now being revived by HMD Global. On the cusp of the launch of a new ‘flagship’ model, the Nokia 6.1 plus, it’s also interesting to see the ‘re-introduction’ of some ‘classic’ phones, the 8110 and 3310, harking back to those early beginnings.

Keeping Customers Operational – ‘telling’ not ‘selling’

@YellowsBestLtd our mission is to provide our Customers with Management Services and Solutions so their infrastructure networks continue to serve and perform – “Keeping Customers Operational

Needs vary from the launch of the latest IT and Telecoms technologies through to the support of well-established legacy systems.

Given that each organisation is unique, both in its business practices and deployed infrastructure, then we find that its best to take a flexible approach and provide tailored services to suit exacting demands.

Our no-cost and no-obligation Customer consultation is all about finding out needs, regardless of technology or manufacturer, and then sourcing the required solution(s), which may mean seeking out difficult to obtain products or requiring the supply of specialist services.  So in essence, it’s not about us ‘selling’ them something we have, but rather our clients ‘telling’ us what to provide. Making it easier and more convenient for busy procurement and operational teams,  saving them effort, time and cost.

We’re always keen to see how we can enhance our range of #business services, increase the #enterprise infrastructure we support and expand our mix of #systems solutions to supply the required #technologies and products for our customers.

Please help us understand what services would be of interest to you to  support your systems requirements, by getting in touch; we look forward to hearing from you.
