Just our of interest, do you people have some award ceremony with prizes for things such as:

Best Design for inaccessable Motherboard battery

or

Most user unfriendly socket on a motherboard

Let me know, wont you.

A motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, while providing connectors for other peripherals. The motherboard is sometimes alternatively known as the main board, system board, or, on Apple computers, the logic board. It is also sometimes casually shortened to mobo.

Prior to the advent of the microprocessor, a computer was usually built in a card-cage case or mainframe with components connected by a backplane consisting of a set of slots themselves connected with wires; in very old designs the wires were discrete connections between card connector pins, but printed circuit boards soon became the standard practice. The Central Processing Unit, memory and peripherals were housed on individual printed circuit boards which plugged into the backplane.

During the late 1980s and 1990s, it became economical to move an increasing number of peripheral functions onto the motherboard (see below). In the late 1980s, motherboards began to include single ICs (called Super I/O chips) capable of supporting a set of low-speed peripherals: keyboard, mouse, floppy disk drive, serial ports, and parallel ports. As of the late 1990s, many personal computer motherboards supported a full range of audio, video, storage, and networking functions without the need for any expansion cards at all; higher-end systems for 3D gaming and computer graphics typically retained only the graphics card as a separate component.

The early pioneers of motherboard manufacturing were Micronics, Mylex, AMI, DTK, Hauppauge, Orchid Technology, Elitegroup, DFI, and a number of Taiwan-based manufacturers.

Popular personal computers such as the Apple II and IBM PC had published schematic diagrams and other documentation which permitted rapid reverse-engineering and third-party replacement motherboards. Usually intended for building new computers compatible with the exemplars, many motherboards offered additional performance or other features and were used to upgrade the manufacturer’s original equipment.

The term mainboard is archaically applied to devices with a single board and no additional expansions or capability. In modern terms this would include embedded systems and controlling boards in televisions, washing machines, etc. A motherboard specifically refers to a printed circuit with the capability to add/extend its performance and capabilities with the addition of “daughterboards.”

It’s been a busy couple of weeks on the project. I had a few vacation days left to take at work, so I nabbed a week off and put it to good use making some progress. With the basic shell assembled and painted, I wanted to get onto the basic computing power for the sim, and in particular to creating the various mountings needed to place the various bits in the shell.

As I mentioned in a previous installment, I plan on putting all the computing and electronics gear needed for the sim into the shell itself, so that it’s essentially self-contained. This contrasts with some other sims where the computing power is a stack of beige boxes lined up against the next-door wall – there’s nothing wrong with that approach, I just wanted something that was all-in-one.

In Phase 1, the sim will be powered by four PCs: two ‘conventional’ PCs, an HP tablet PC and a recycled Asus R2 ultra-mobile PC (UMPC) that I happened to have lying around doing nothing. One conventional PC (PC1) will power the main display and nothing else at all – most likely I’ll even have sound disabled on this machine so that all the CPU power available goes to rendering the front view and get the frame rates up as high as I possibly can. The second conventional PC (PC2) will run the left and right-hand screens that will serve as PFD/MFD in glass cockpit aircraft, and analog panels in others, and will also be the place where most of the controls (yoke etc) plug in via USB. The tablet PC (PC3) will serve as an additional control panel display, but – with its touch screen – will also be a control center, where the custom screens I’m planning to write to control aspects of the sim itself and of simulated aircraft where I have no physical controls available – engine fuel feeds, for example – will also run. Running off PC3 will be a second, 7″ touchscreen monitor which will be physically located in the pedestal and will provide a radio stack. Lastly, the UMPC (PC4) will be located in the pedestal and will serve as CDU, weather radar and various ancillary screens that would normally appear in that position.

By way of specs, PC1 is powered by a quad-core Q9450 chip which runs stock at 2.66GHz but can be clocked to 3.2GHz and even a bit further quite happily in my experience; PC2 runs on an older quad-core Xeon X3210 which runs stock at 2.13GHz but I have been able to push to 2.7GHz reliably. Neither of these are as fast as you can get, although the Q9450 overclocked is very competitive with anything else in the Core 2 Quad range. Both boards have 4GB DDR2-800 RAM on them. For now I’m holding off going to Core i7, though at some point I’ll most likely want to do so for the main rendering board. PC3, the tablet, uses a Core 2 mobile chip running at 3GHz and has 2GB RAM on board, with a 13″ 4:3 touch (sadly not multi-touch) screen. PC4, the UMPC, is rather underpowered compared to all the others, designed as it was as a small, low-heat platform. It runs a Pentium 4-class Celeron at a meagre 900MHz and sports a rather insipid 1GB of RAM, but since its purpose in the sim is to run a single panel at a time and be touch-sensitive, this it does reasonably well. It’s also the only PC in the solution which will be running Windows XP rather than Windows 7, simply for the hardware support and memory overhead.

PC1 and 2 exist in the form of bits and pieces – motherboard, CPU etc pulled together from previous projects and upgrades with some bought new for the project. They are not complete PC systems; although one is made from parts mostly pulled from a server which had a case and was in use as a development server, I am not attempting to install a whole PC enclosure inside the shell – it just wouldn’t fit. Instead I’m going for a barebones approach and as such, I needed to construct an enclosure and mounting system for these PCs within the main shell.

Originally I was going to put one board on the left-hand side of the console at the rear, and the other on the right, but a quick check of dimensions proved that I wouldn’t have room left to mount the control yokes, and I can’t re-size those. I then settled on a plan to mount them in a double-decker style in the middle of the console behind the mounting for the tablet PC, where there will be no embedded control hardware. This left me needing to fashion some form of enclosure.

Since wood, rather than metal, is my medium for this project, it would be necessary to create a wooden frame. This would be open to maximise airflow. I set out by measuring up the ATX motherboard dimensions and then cutting out two panels of 6mm MDF with a 20mm margin around the edges to provide room to place support structures. In the event I mis-measured and left only a 10mm margin and was forced to adapt a little later on rather than start again. I used scrap wood left over from earlier in the build, which is why the finished result doesn’t look hugely polished; as it’ll never be seen in normal use, it doesn’t need to be, and my stock of untouched MDF can be used for other purposes.

Next I took a scrap old AMD K7 motherboard (which is ancient, but ATX has stayed the same for countless years so it was fine as a template I could afford to get dirty and broken) and used this to mark the positions of the screw-holes where the board is screwed into the retainers. I had to pop off to Maplin to get a packet of motherboard retaining bolts so I could populate out the board with them.

Putting retaining bolts onto the 'bottom deck' board

Once this was done with both boards I measured the height of a standard PC expansion card to the retaining rail where the card is screwed in, as I would need to provide a similar support structure in my frame. I then cut some pine baton down to the right length to act as supports for the top deck, and positioned these around the edge of the bottom board.

Support pillars in place, with K7 motherboard in as a test

Into the top of each pillar I drilled a deep 4mm hole to accomodate a machine screw. I then drilled a wider 8mm hole, 4mm deep, at the top of each 4mm hole – this was, in hindsight, the wrong way to do it. I should have drilled the larger hole first and then I’d have had a better guide for the smaller hole; but with a drill press this is immaterial provided you keep the material fixed in the right place. Into the larger hole I placed a nut for a 4mm machine screw and glued it into place. I could then screw a 4mm bolt into the pillar with the nut acting as the anchor. Finally I drilled 4mm hole in the top deck board in the appropriate place, and could then mount one on top of the other.

A further two batons went on the bottom deck right at the rear of the structure, with two more directly above them on the top deck, cut and grooved to interlock to provide a single long baton running the full height of two boards + full-height expansion cards, and then into the top of those batons I drilled 6mm holese and put 6mm tee nuts to accomodate 6mm roofing bolts. A strip of MDF (made deliberately over-wide for reasons which will become clear later) went on top and provided a support structure for the expansion cards on the top deck. Two smaller strips of MDF were then run up the back of the vertical support batons and tee-and-bolt combinations placed in them at 3 locations to lock the whole structure together when assembled. The finished product looks like this:

Completed double-deck frame for PC1 and 2

This whole structure fits into the central part of the console and is bolted down with four bolts at the corners into the main shelf of the console.

Next, I needed to mount the power supply units to run these two PCs. Originally I tried constructing a shelf behind the PC enclosure, keeping the PSUs in place with artfully-bodged screws and a couple of angle-brackets (these actually work really well, and again, ‘polish’ wasn’t the aim here, so don’t knock it!).

PSU shelf, Take 1

Sadly, this pushed the main PC enclosure frame so far forward that the full-length graphics card used would foul the tablet PC mounting, so I had to abandon this. I went for the simplest thing that could work, which was to split the shelf in the middle and mount the two halves on the other side of the vertical divider in each case, like this:

PSU shelf, Take 2

An extra steel support bracket was used for each to help bear the weight of the PSU. Keeping the PSU up high like this to give clearance below for the other parts – notably the yoke assembly – is critical, so a shelf was necessary.

Once I tried to plug it all in for a test, of course, I discovered that the ATX power and P4 ancillary power leads on both PSUs were just too short to reach. In modern PCs the PSU is located close to the main board and there’s no need to have miles of free cable. While some PSUs provide more than others, one of the supplies I was using for the project had particularly short cables. No amount of bodging was going to fix this. So, a further trip to Maplin bought me a pair of ATX and P4 cable extensions, designed for installing PSUs into large server cases. With these, I was finally able to make all the connections with room to spare. Time to fire the PCs up and make sure they still work!

It lives! Both PCs fired up and running.

To my relief, both of them fired up immediately, so I shut them down, put the displays for PFD and MFD into place on the front panel, and connected them up. You’ll have to take my word that they’re working in the picture below, because my lousy phone camera is unable to deal with the contrast in the shot and is overwhelmed by the glare (I must remember to recharge my proper camera and start using that for picture-taking):

No, it's not the Amityville Horror house...

Each PC will now be outfitted with a brand new solid-state drive (SSD) which should help it go like lightning, reduce noise and power consumption and – importantly – heat. Because neither needs much local storage, I’m putting 60GB models in both. The tablet and UMPC both have small laptop HDDs which I will leave in for now.

Next up is work on the yoke. I need to convert a standard CH Products yoke, adding 120mm to its shaft length, and finding a way to fit it permanently into the console. Soldering iron time…

Computer hardware are all part of the physical computer, and are distinguished by the data in it or who operate in it, and are distinguished by the software (software) that provides instructions for the hardware to complete the task.

Boundary between hardware and software will be a little blurry when we speak about firmware, because this firmware is software that is “made” into the hardware. This firmware is the area of computer science and computer engineering, which is rarely known by the general user.

You might be wondering why you hear an unfamiliar noise from your CPU and you sometimes face a hardware error that you don’t even understand.

Maybe this video can help you out a little bit..

It might range from CPU Fan malfunction to Processor slowing down to Heatsinks that can’t be used so try to check this out..

Possible Questions regarding troubleshooting CPU and Motherboard Errors:

a. Why should I even bother troubleshooting the problem?

– Troubleshooting problems by yourself saves up the time and money. It also increases your knowledge regarding these kinds of situations you would encounter lately.

b. Then if I try to fix the problem, would the procedures be easy?

-It would be easy if you know the know-hows of the parts but if you also follow the instructions carefully and try not to guess what’s next to do then you’re gonna be fine. Fixing it would range from just reseating the component to removing the component then placing it back could fix the problem.

c. Would this fix the problem?

-There are some instances that when doing the procedures, it leads to failure so that just means that the component needs to be replaced.

And one more thing, always check the safety precautions before opening and never do anything unless you know something about what you are going to do.

Gigabyte’s been listening to all of the iPhone syncing issues from motherboard owners using Intel’s P55 chipset. They’ve put out a beta BIOS that addresses the problem. Unfortunately, that doesn’t help all the Asus and MSI users who are having the same troubles, but hopefully now that Gigabyte has set an example the others will follow.

If you’re one of the unlucky few, hit the link to grab the update. [Gigabyte via PC World]

I acquired a shiny new mini-ITX box with an Intel D945GCLF2 the other day to replace an ageing Pentium II box. Installation went smoothly (after some initial messing with what to boot from): I started from a lenny amd64 live CD and debootstrapped from there, making use of dpkg --get-selections and dpkg --set-selections along the way and aptitude to finish the job and mark various packages, mostly library packages, as automatically installed.

/etc, /home and a few other directory trees came from its predecessor, which wasn’t too painful since that was also running lenny. Some light tweaking was done, what with it being a different computer.

(I did consider running a 64-bit kernel with 32-bit userland, which would have meant just copying from the old box’s HD. Obviously easier, but less fun.)

In use

It’s now in service and doing its job well. There are only three issues that I can see at present, both minor:

• I can’t plug in the case’s built-in speaker (one of the usual PC bog-standard beepers). No great loss.
• The custom kernel which I’ve built for it (2.6.27.38) doesn’t seem to shut everything down properly: I checked its power usage with a power meter and found it still using about 20W despite being in standby. I’ve probably missed something silly… again, not a problem, since I’m leaving it on 24/7 anyway.
• Others have reported that the northbridge fan is noisy, but I think that it’s just a little noisier than it might be.

Normal idle power usage is around 41W, about 5W or 6W of which is due to the hard disk. I was slightly surprised to find that the old PII box used 43W when idling – I was expecting more – but then it uses up to 70W under load compared to the new box’s 45W.

(The PII box has one 160GB IDE HD, a CD-ROM drive and one four-port USB2.0 card; the Atom box has one 250GB SATA HD. I’ve not measured without said hardware; suffice it to say that the older HD probably uses a watt or two more.)

Obligatory benchmarking

If I don’t include this, I’m sure that somebody sooner or later will complain

Kernel build timings weren’t too far off my main desktop box’s timings, at least when using CONCURRENCY_LEVEL=4 fakeroot make-kpkg kernel-image (not that dissimilar to make -j4 deb-pkg): it took almost 11 minutes, which is about 2 minutes slower. (The desktop box has an Athlon 64 3500+.) Without any explicit use of parallel processing, it took about 23½ minutes.

Blind flash BIOS dikenal juga dengan istilah Boot-Block BIOS adalah trik yang digunakan untuk mengembalikan BIOS seperti sediakala bila terjadi kegagalan BIOS pada motherboard. Biasanya BIOS motherboard corrupt dikarenakan proses update BIOS yang gagal. Yang dibutuhkan adalah file BIOS sesuai dengan motherboard yang bisa diperoleh dari website vendor motherboard atau dari beberapa website lain (Wim’s BIOS berbaik hati membuat rangkuman linknya di sini) dan Floppy Disk.

Cara-cara ini saya peroleh dari website motherboard MSI (link persisnya sudah lupa). Saya sendiri belum pernah mengalami kegagalan flash BIOS atau kerusakan file BIOS karena sebab-sebab lain, jadi trik ini belum pernah saya coba.

AMI BIOS

1. Rename AMI BIOS file menjadi AMIBOOT.ROM lalu save ke floppy disk. contoh: Rename A569MS23.ROM to AMIBOOT.ROM
2. Masukkan floppy disk tadi ke floppy drive. Nyalakan komputer, tekan dan tahan Ctrl+Home untuk memaksa update. Hal ini akan membuat komputer membaca file AMIBOOT.ROM dan me-recover BIOS dari drive A.
3. Setelah terdengar suara 4x beeps, keluarkan floppy disk dan restart Komputer.

AWARD BIOS

1. Buat bootable floopy disk.
2. Copy Award flash utility & BIOS file ke floppy disk tersebut.
3. Bikin file autoexec.bat dan masukkan parameter “awdfl535 biosfilename” misal: awadfl535 a619mj21.bin
4. Boot up komputer dengan floppy tersebut (sekitar 2 menit akan keluar tampilan)
5. Re-flash BIOS & reboot.

PHOENIX BIOS

Anda bisa menggunakan Phoenix BIOS Recovery Disk langkah-langkah penggunaannya dijelaskan di rechner.org (tersedia juga link direct download disana)

WismBIOS : How to recover a corrupt BIOS ?

Menjelaskan 4 teknik untuk melakukan flashing BIOS bila BIOS asli corrupt. Teknik nomor 4 bisa digunakan untuk beberapa tipe motherboard Intel yang dilengkapi Flash Recovery jumper.

Penjelasan dari 0scil0sc0p3 :

Belajar sih boleh aja….tapi ya Gw jadi malu…lha Gw sendiri aja masih cupu dan masih perlu banyak belajar…

Sebenarnya sih untuk nanganin masalah itu ngga perlu repot2 kok….yg terpenting ya keberanian…Sebelum terus, Gw mau tanya dulu ama loe berani apa ngga…? soalnya dari yg Gw baca di forum kayaknya loe masih agak2 ragu gitu…

Untuk flash bios yg bermasalah atau corrupt karena gagal flash itu sebenarnya ngga perlu pakai mobo yg sejenis untuk flash ulangnya….loe bisa gunain mobo apa aja asal yg penting penggunaan kapasitas chip biosnya sama ama mobo yg nantinya akan loe pakai…bahkan ada beberapa mobo yg pakai bios Award sebenarnya bisa loe flash langsung pakai mobo itu sendiri.

Kalau loe pakai mobo lain (dan ini satu2nya jalan untuk mobo yg pakai bios AMI) maka loe harus memberanikan diri untuk melakukan prosess cabut pasang chip bios pada mobo dalam keadaan hidup (disini perlu kehati2an dan keberanian)…Jadi loe hidupkan mobo yg bagus seperti biasa dan masuk ke DOS mode….setelah di DOS mode loe cabut bios mobo yg bagus itu lalu loe pasang chip bios yg bermasalah (ingat chip2nya harus yg sama kapasitasnya ya) setelah selesai pasang chip yg bermasalah maka loe bisa flash chip bios tersebut seperti biasa…paling nanti disaat prosess flash ada error sedikit…tapi itu loe abaikan aja, karena error itu cuma pendeteksian kalau mobo yg loe pakai itu ngga sesuai dengan file bios yg akan loe flash nanti…so, loe lanjutin aja sampai selesai…setelah selesai dan restart loe bisa cabut chip bios tersebut dan loe pasang lagi dimobo asalnya dan lihat hasilnya.

Itu tadi pada AMI bios…nah kalau pada Award bios itu lebih mudah karena ada beberapa system yg tetap bisa mencari system file ke disket walaupun biosnya corrupt dan ada tampilan pada layar yg hanya sampai ke A:\ saja…kalau seperti ini mah enak banget…loe cukup sediakan disket startup DOS yg sudah berisi file bios dan Flashernya dan juga file autoexec.batnya untuk prosess eksekusi otomatis bila perlu….loe bisa gunakan disket tersebut untuk prosess flash bios ulang.

Tapi ada juga yg tidak memberikan tampilan ke monitor tapi tetap mencari file ke disket. untuk mengetahui apakah system loe yg biosnya corrupt itu bisa mencari file ke disket atau tidak itu mudah…loe liat aja di floppy drivenya, lampunya nyala atau tidak…kalau lampu floppynya nyala sesaat maka loe bisa gunakan disket tadi untuk prosess flash bios ulang. Tapi loe mungkin perlu file autoexec.bat untuk prosess flash otomatisnya…kenapa..? ya karena loe ngga bisa lihat prosessnya gimana dilayar monitor…bener ngga..?

ini adalah parameter yg sering Gw pakai untuk prosess flash otomatis dibios Award.

award xxxxx.bin /py/sn/cc/r enter

award = flash utility
xxxxx.bin = file biosnya
/py/sn/cc/r = option pada flash utility agar bisa lakukan flash secara otomatis. untuk lebih jelasnya loe bisa lihat help pada award.exe nya

Tapi kalau kedua kondisi diatas tidak terjadi pada mobo loe yg pakai bios award…maka jalan terakhir ya tetep pakai cara pertama…yaitu gunakan mobo lain yg ukuran biosnya sama dan cabut pasang chip bios dalam kondisi On…mobo ngga perlu sejenis…tapi pada option flash utility nya biasanya saya pakai /F juga…ini maksudnya untuk prosess force, biar prosess flash tetap bisa dilakukan walaupun kita menggunakan mobo dan bios yg berbeda dari file bios yg akan kita tulis nantinya.

Semoga ini bermanfaat

Salam,

Motherboard dengan Fitur Backup BIOS

Beberapa vendor untuk motherboard seri tertentu melengkapinya dengan fitur backup BIOS untuk memudahkan recovery bila terjadi kegagalan BIOS cara untuk recovernya terdapat di manual setiap motherboard tersebut. Contoh :

• Gigabyte dengan fitur Dual BIOS
• Albatron dengan fitur BIOS Mirror
• Intel dengan Flash Recovery Jumper
• ECS dengan Top Hat Flash
• Asus dengan CrashFree BIOS (memungkinkan pengguna untuk mengembalikan data BIOS yang rusak dengan menggunakan flash disk USB yang berisi file BIOS).

Bila anda mengalami kesulitan dengan cara-cara telah disebutkan ada cara sederhana yaitu membawa motherboard ke distributornya untuk diflash ulang, jika masih dalam masa garansi untuk masalah seperti ini biasanya distributor tidak akan mengenakan biaya. Ada juga distributor yang malah memberikan layanan update BIOS secara gratis contohnya untuk merk Abit anda bisa menghubunginya distributornya di :

P.T. Spectrum Utama

Kabar buruk untuk para pecinta motheboard DFI, sebuah merk yang cukup terkenal di kalangan overclocker karena produknya yang sering berkualitas tinggi telah ditemukan beberapa motherboard DFI palsu yang beredar di pasaran Indonesia.

Saya sendiri mengetahui informasi ini dari thread yang dibuat Pak Wasis perwakilan salahsatu distributor resmi DFI di Indonesia (DPJ) di Forum CHIP : DFI Mainboard Palsu?!.

DFI Taiwan sudah mengeluarkan pernyataan resmi mereka yang dapat dilihat di sini. Semakin memprihatinkan bahwa produk palsu disebutkan didistribusikan oleh distributor lama DFI di Indonesia yang sudah dicabut haknya untuk mendistribusikan produk DFI di Indonesia secara resmi. Pihak DFI Taiwan dan para distributor resminya sudah mengambil beberapa langkah yang diperlukan dan bila perlu membawa masalah ke meja hukum. Pak wasis selaku perwakilan DPJ tidak bisa menyebutkan nama distributor lama yang dimaksud.

Saya dan banyak orang lain tahu distributor produk DFI sebelumnya adalah Sempurna Computer. Saya sudah mengirimkan email ke pihak sempurna dan sejauh ini belum ada tanggapan dari mereka.

2 distributor resmi DFI di Indonesia sekarang sesuai pernyataan di situs resmi DFI adalah :

DINAMIKA PERKASA JAYA (DPJ)
Jl. Kaliurang km 5.5 Gg Pandega Mandala
23 Yogyakarta – INDONESIA 55281
TEL : +62-274 554499, 7412787
info@dpj.co.id

FirstCom
Harco Mangga Dua Blok A1 no.1,
Jakarta 10730 – Indonesia
TEL : +6221-62203662
FAX : +6221-62203664
info@firstcom.web.id

Sejauh ini baru ditemukan 2 tipe Motherboard DFI yang dipalsukan yaitu DFI-MCP73V dan DFI MCP68V Gambar resolusi tinggi dari motherboard palsu (thanks to Pak Wasis) dapat dilihat di :

• Fake model 1: DFI-MCP73V
• Fake Model 2: DFI-MCP68PV
• Fake Model 2: DFI-MCP68PV (Box)

DFI-MCP73V palsu memiliki kemiripan dengan produk dari vendor J&W yaitu JW-IN7100-HD dan untuk DFI-MCP68PV memiliki kemiripan dengan JWT-N68PV (hasil analisa jomblosejati alias Pak Gunawan).

Untuk perbandingan gambar produk J&W tersebut :

• JW-IN7100-HD versi Non Full Solid Caps (gambar asli milik itsvet.com)
• JW-IN7100-HD versi Non Full Solid Caps (diupload oleh non)
• JW-IN7100-HD versi Solid Caps (diupload oleh jomblosejati)
• JWT-N68PV (diupload oleh jomblosejati)
• JWT-N68PV (diupload oleh jomblosejati)

Update link produk J&W langsung dari situs resminya :

• JW-IN7100-HD
• JWT-N68PV

Bila tebakan tersebut benar, maka kasus pemalsuan ini menggunakan teknik re-label (mengganti identitas pembuat asli dengan merk lain dan bila diperlukan dibuat pula kemasan baru).

Sesuai pernyataan DFI di situs resmi mereka saat ini produk baru DFI yang beredar secara resmi di Indonesia hanya ada 9 tipe yaitu :

Pihak J&W telah memberikan tanggapan sebagai berikut :

Official declaration to rumors spreading in the Indonesian market

14th April, 2008.

Dear all J&W distributors and customers,

Over the last week, we have received many enquiries from our distributors and OEM customers concerning the fake ‘DFI” branded motherboards case discovered in the Indonesian market.

We checked in details with those information provided by them and we noticed that those board pictures were taken from our high-quality motherboards manufactured; yet, they are not branded as “DFI” by J&W. We must emphasize that we did not and this is an official declaration.

After tracing all our sales record to the Indonesian market, we found that on January 2008, a company named “Tiga-Dimensicom” had purchased a certain quantity of MCP68PV and MCP73V motherboards from J&W, which they claimed are for OEM & project purpose, and no J&W brand logo should be included in the motherboard, manual, driver disc and BIOS as requested. (Note: We may provide evidences to related parties upon requests, but we will not disclose them here.)

These motherboards left our factories legitimately without any infringements. We did not, and we absolutely would not support this kind of infringement activities, which is illegal and immoral.

During these few days, we also received reports that the Indonesian and Philippines distributors of one of the motherboard manufacturers accused us, J&W, for making such faked motherboard under the “DFI” brand name. We hereby declaring that we did not, and will never, manufacture pirated products which would infringe the intellectual properties/ copyrights of other parties. We only produce OEM/ODM products for our customers under their brand names when authorized. We hereby also condemn these types of activities conducted by them to discredit our company’s image and are asking for a STOP of that. We reserve all the rights for legal actions against them.

Yours sincerely,

J&W Technology Limited

Silakan lihat sendiri di situs resmi J&W di sini.

Dan sekali lagi menurut jomblosejati, Tiga-dimensicom adalah afiliasi dari Sempurna bisa diperhatikan dari label dan stiker pada produk DFI lama yang pernah didistribusikan Sempurna tampak gambar angka 3 dan huruf D.

Ada pula beberapa iklan yang tampak menjual produk palsu ini :

• Dynacom Surabaya
• Egrosir

Bisa jadi yang membuat iklan tidak mengetahui bahwa produk DFI yang mereka jual adalah palsu, semoga mereka dapat memberikan penjelasan.

Untuk para calon pembeli DFI agar tidak ragu membeli produk DFI ada beberapa tips :

1. Pastikan produk DFI yang anda beli di toko komputer berasal dari distributor resmi (saat ini DPJ & Firstcom) bisa lihat segel di badan motherboard atau tanya langsung ke tempat anda membeli.
2. Sebelum membeli lihat dulu ke situs resmi DFI, apakah produk tersebut tercantum di sana dan didistribusikan untuk wilayah Indonesia.
3. Bila ragu silakan menghubungi pihak distributor resmi DFI di Indonesia selain melalui kontak diatas, pihak distributor resmi DFI sudah membuka perwakilan di Forum CHIP : DFI Represented.

Tambahan informasi dari Pak Wasis (DPJ) :

label kita biasanya pake yang ada tulisan HIS dilingkari semacam gergaji bunder… ke depan kita pake segel yang resmi untuk produk DFI kita, yaitu DFI Indonesia… sementara blm bisa post, krn segel sih bkn masalah untuk sekarang. Krn yg palsu sdh pasti model MCP73PV dan MCP68. TIPE2 lain, tidak ada.

Aa Noto sudah membuat postingan di blog yang bersangkutan tentang kasus ini. Bahkan beberapa situs IT terkenal sudah sudah memberitakannya antara lain slashdot, vr-zone dan techarp. Adapula komentar menarik khususnya mengenai posisi J&W di jonnyguru-forum.

Anakart Nedir?

Bilgisayar donanımlarını birbirlerine bağlamak ve koordineli halde çalışmalarını sağlamak için kullanılan bir donanımdır. Parçaların aralarında iletişim kurmasını ve gerekli işlemlerin gerçekleşmesini sağlamak için anakartlar üzerinde harici işlemci yanında kart işlemcileri de bulunmaktadır. Chipset olarak ta adlandırılan bu işlemcilerin bilgisayar performansı üzerinde çok etkili oldukları bilinmektedir. Dahili parçaları birbirine bağlamanın yanında bilgisayarı dış çevre ile iletişimini (ses, görüntü, veri) sağlamak içinde üzerinde portlar bulunmaktadır. Kısaca bilgisayarların olmazsa olmaz parçasıdır. Günümüzde birçok anakart üreticisi firma (intel, asus, gigabyte, msi, dfi vs..) genellikle birkaç chipset üreticisinin işlemcilerini kullansalar bile kartlar üzerindeki diğer donanım ve araçlar ile birbirlerine karşı üstünlük sağlamaya çalışmaktadırlar.

Anakartların Temel Parçaları ve Görevleri
Diğer bilgisayar donanımlarını ve dış dünya ile iletişimi sağlamak için anakart üzerinde çeşitli portlar ve entegreler (işlemci ve diğer) bulunmaktadır. Aşağıdaki resimde örnek bir anakart devresinin üstten görüntüsü bulunmaktadır.
Yukarıdaki resimde gözüken anakart ile diğer anakartlar arasında mantık ve çalışma prensibi olarak çok fazla fark yoktur. Devre üstünde bulunan parçalardan diğer anakartlarda da bulunan anakartların ortak parçaları olan adlandırılan çalışma birimlerini inceleyecek olursak;

Anakart İşlemcisi – Dahili İşlemci (Chipset):

Yukarıda da kısaca bahsettiğimiz gibi, anakartlarda parçalar arasındaki veri transferlerini ve anakartı dışarı ile çeşitli bağlantılarını sağlamak için anakart işlemcisi olarakta adlandırılan chipset işlemcileri bulunmaktadır. Örnek olarak harddisk üzerindeki bir veri işlemci ile işlenirken veya işlemcideki bir veri ekran kartı üzerinden görüntüye dönüştürülürken bu entegreler üzerinden transfer yapılmaktadır. Bilgisayara takılı olan parçalar genellikle farklı hızda ve türde iletişim birimlerine sahipleridir. Birbirleriyle direk olarak haberleşemezler işte burda da yine chipset’ler devreye girmektedir. Aradaki bu farklılıkları ortak bir merkezde toplayarak parçaların uyum içinde haberleşmelerini sağlamaktadır. Aşağıdaki resimde yukarıdaki anakartın Kuzey Köprüsü işlemcisi yani kart üzerindeki iki dahili genel işlemciden biri gözükmektedir.

Dahili işlemci (chipset) hızları çok yüksek olduğu için ve mimarileriyle de ilgili olarak ısınmalar gözükmektedir. Bu nedenle parçalar için soğutucu modüller kullanılmaktadır. Birçok aletin aynı zamanda haberleşmesini ve birbirlerine veri transferi yapmasını sağlayan bu entegreler anakartların en temel parçalarındandır. Şu anda birkaç büyük firma (intel, nvidia, via ..) bu chipsetlerin üretimini üstlenmiştir. Anakart üreticilerinin bir çoğru bu firmaları özellikle intel ve nvidianın chipsetlerini kullanmaktadır.
Dahili Parça Portları
Bu portlar bilgisayar kasası içinde bulunan ve genellikle sadece dış bağlantılarını gördüğümüz kartların ve parçaların bağlandığı portlardır. Aşağıdaki anakart resminde numaralandırdığımız portlar ve görevleri aşağıda verilmiştir.

1.PCI Portları: Bu portlar bilgisayara satın aldığımız, ekran kartı dışındaki kartları bağlamak için kullandığımız portlardır. Örnek olarak ses kartı, televizyon – tv kartı, ethernet kartı, güvenlik kartı gibi kartlar bu portlara bağlanmaktadır. PCI portunun veri hızı 33 MHz veya 66 MHZ düzeyindedir. 124 pi ile tek seferde 32 bitlik bir veri transferi sağlamaktadır. 3.3v veya 5v düzeyinde çalışma gerilimine sahip olup 32bit adresleme yapabilmektedir (4GB). Son olarak ta saniyede 133MB veri transferi yapabilmektedir.
2.PCI Express Portları: Bu portlar PCI slotunun yerini almak için tasarlanmıştır ve çok yakın zamanda artık kartlarda sadece bu portlar kullanılacaktır. Veri transfer hızları ve ergonomisi sebebiyle PCI ile kıyaslanmaz derece güçlüdür. PCI Express 1.1 ve PCI Express 2.0 versiyonları mevcuttur. PCI Express 1.1 de 2.5GB/Saniye veri transfer hızı PCI Express 2.0 da ise bunun iki katı yani 5GB/saniye veri transfer hızları yapılabilmektedir. Yeni üretilen dahili kartlar (ses, tv, mpeg decoder vs…) artık bu teknolojiye uygun olarak üretimlerini arttırmaktadırlar.
3. PCI EXPRESS X16 Portu: Bu slot ise AGP ye alternatif olarak geliştirilmiştir. Temelde PCI EXPRESS mantığını kullanmaktadır fakat katman sayısı çok fazla olduğu için veri transfer hızları inanılmaz boyutlara ulaşmıştır. Bazı anakartlarda iki adet bu slottan bulunmaktadır. Temel mantık iki ekran kartını aynı anakarta bağlayarak görüntü işleme kalitesini dahada yükseltmektir. Ekran kartları için tasarlanan PCI EXPRESS X16 slotu saniyede 4GB veri transferi sağlamaktadır. 16 hat kullanmakta ve her hat saniyede 250MB veri transferi sağlayabilmektedir. Yeni nesi ekran kartlarının tamamı bu slot yapısına uygun olarak üretilmektedir.
4.IDE – ATA Portu: Bu port ise bilgisayarımıza CDRom, CRrewriter, DVDRom, IDE Destekli Harddiskleri bağlamak için kullanılmaktadır. Integrated Drive Elektronics – Dahili Sürücü Elektroniği terimlerinin kısaltması ile elde edilmiş olan bu arabirimin üst versiyonları 100MHZ hıza ve 48 bit ile 144PB depolama kapasitesine sahiptir. Paralel ATA olarak adlandırılan bu arabirimde veriler 40 gözlü kablolar ile iletilmekte ve aynı kablo üstüne birden fazla IDE destekli parça takılabilmektedir.
5. Sata ve Sata 2 Portları: Bu portlar ise ATA arabiriminin paralel moddan seri moda ve bazı geliştirilmeler yapılmasıyla elde edilmiştir. Veri transfer hızları çok büyük ölçüde artmakla birlikte yeni sürümde sata 2.0 ile 3.0Gb/saniye veya 300MB/saniye veri transferi sağlayabilmektedir. Kullanılan kablo teknolojisi ile kasa içinde daha ergonomik bir kullanım sağlanmaktadır. 4 Pin ile harddisk anakart arasında veri iletişimi sağlanmaktadır. Yakın zamanda sata 3.0 ın çıkması ile birlikte veri transfer hızı 6.0Gb/Saniye düzeyine çıkacaktır. Bu portlar anakart işlemcilerine direk bağlantılı değildir. Kablolardan gelen veriler öncelikle bu iletişim protokolü için özel olarak üretilen sata kontrolcü entegreleri tarafından işlenip chipsete aktarılmaktadır.
6. Distek Sürücü Bağlantı Portu: Bu porta ise disket sürücüler bağlanmaktadır. Son derece sınırlı bir transfer hızına sahiptir ve ergonomik olarak kullanışlı değildir. Yeni nesil pclerde artık bu slot kullanılmamaya başlanmıştır.
7. Güç Bağlantı Portu: Kasada bulunan güç kaynağından (power supply) anakarta gerekli olan gücü sağlamak için yapılacak bağlantıda kullanılacak olan porttur. Sağlam bir şekilde karta monteli olup kart için gerekli olan +5v -5v +12v güçleri buradan sağlanmaktadır.
Dahili parçalar için kullanılan portları ve çalışma şekillerini yukarıda anlattık. Diğer sabit parçalar ve bağlantı portları ile ilgili bilgiler aşağıda bulunmaktadır.
Dahili Parça Portları – İşlemci ve Ram
Bu soketlerin diğer bağlantılardan farkı, anakart üzerinde takılı kalmaları ve bilgisayarın en önemli parçalarından ikisi olmalarıdır. Bilgisayar üzerinde yürütülen ana işlemleri hepsi bu iki parça üzerinde yapılmaktadır.
İşlemci – CPU Portu: İşlemci kendisine gelen komut ve bilgileri uygun şekilde işleyerek çıktıları ram ve diğer gereken parçalara aktarmaktadır. Bilgilerin büyük kısmı ram üzerinde toplanacağı için bu iki parça arasında çok fazla sayıda bağlantı vardır ve genellikle birbirine yakın pozisyonda tasarlanırlar. Aşağıdaki resimde örnek bir işlemci slotu gözükmektedir.

Bu slotlar genellikle değişik standartlarda üretilirler. Günümüzdeki en önemli iki işlemci üretici firmanın ürettiği ve kullandığı genel standartlar;
Intel İşlemcileri için: Soket 370, 423, 478, 479, 486, 495, 603, 604, 611, LGA 775
AMD İşlemcileri İçin: 563, 754, 939, 940, AM2, AM2+, AM3, 1207 gibi soketler kullanılmaktadır. Bizim resmimizde bulunana soket LGA 775 soketidir. Bu soket türlerinde erkek bacaklar anakart üzerinde bulunmaktadır.
İşlemciler çalışırken ısı seviyeleri yükseldiği için soğutulmaya kesinlikle ihtiyaçları vardır. Hatta pasif değil fan montajı ile aktif olarak soğutulmaları gerekmektedir. Soğutucu bağlanabilmesi içinde yuva çevresinde belirli bir boşluk bulunmaktadır. Ayrıca yuvanın çevresinde bulunan parçalar genellikle güç mosfetleri ve regulatör devreleridir. İşlemcilerde voltaj dalgalanmasının çok ufak değerlerde olması yada hiç olmaması tercih edilmektedir. Bu nedenle güç kaynağı regulasyonu yanında anakart üreticileri işlemci için kendi özel geliştirdikleri regulatör devrelerinde kullanmaktadırlar.
Ram Portu – DIMM Port: Yukarıdada kısaca açıkladığımız gibi işlemci ve ram slotları birbirine genellikle yakın üretilirler çünkü aralarında çok fazla kablo bağlantısı vardır ve bilgisayar hızını en çok etkileyen elemanlardır. Ram parçasına kısaca değinecek olursak, normalde bilgileri harddisk üzerinden okuyup işlemek ne kadar hızlı olursa olsun ekranda takılmalar ile karşılaşırız çünkü bir sayfadan diğerine geçerken harddisk üzerindeki verinin alınıp işlenmesi, harddsikin erişim süresinden dolayı gecikir. Fakat ram’lar, üzerindeki bilgileri anında ekrana ve gerekli birimlere aktarma yeteneklerine sahiplerdir. Dolayısıyla gerekli bilgiler işlemci tarafından işlenip ram’e aktarılır ve oradan da gerektiği zaman kullanılırlar. Örnek verecek olursak bilgisayarımızda bir program çalıştırdığımız zaman bu program harddsik züerinden uygun şekilde işlenerek ram bellek üzerine aktarılmaktadır. Program üzerinde herhangi bir işlem yaparken aslında program ram üzerinden çalışmaktadır. Aksi taktirde herhangi bir işlemde veya sayfa değişiminde her defasında harddsik kullanılıyor olsaydı çok fazla zaman kaybımız olurdu.

Yukarıda resimde örnek bir 240 Pin DIMM Ram slotu – DDR2 gözükmektedir. Soket yapılarına gelecek olursak. Ram soket yapı standartları aşağıdaki gibidir;
SDRAM Standartları: 72 pin SO-DIMM, 100 pin DIMM, 144 pin SO-DIMM, 168 pin DIMM
DDR SDRAM Standartları: 200 pin SO-DIMM, 240 pin DIMM bu standartlar DDR2 ve DDR3 içinde kullanılmaktadır.
Boyut olarak 256MB, 512MB, 1GB, 2GB, 4GB gibi standartlar vardır. Anakartların adresleme yeteneklerine bağlı olarak 16GB veri büyüklüğünde ram takılabilecek 4 slot bulunabilir. Ramler üzerindeki bellek entegreleri sayesinde çok büyük verileri kaydedebilirler ve sadece elektrik varken veriler üzerinde durur. Herhangi bir elektrik kesintisinde üstündeki veriler sıfırlanır. Yeni anakartlarda genellikle 4 tane DIMM slotu bulunmaktadır. Dimm slotları kullanılırken eğer elimizde iki tane ram varsa aynı bölgedeki iki slota takılmazlar. 1 tanesi sarıya takılır diğerdie ikinci sarıya takılır. 3 ram varsa işlemciye yakın olan ilk kırmızıya takılır. Ram takma işlemlerini yaparken gerekli belgeleri okumanızı tavsiye ederiz.
Harici Parça Portları
Bu portlar ise bilgisayarımızın içindeki verileri ve bilgilerin dış dünya ile haberleştirilmesini sağlar. Örnek; ses, internet, mouse, klavye gibi parçalar bu slotlara bağlanarak çalışmaktadır. Aşağıdaki resimde bulunan bağlantı portları ve görevlerini inceleyecek olursak.

1. Klavye ve Mouse Portu: Bu portlar ile klavye ve mouse gibi aygıtlarımızı pc’ye bağlarız. Dışarıdan gireceğimiz bilgiler ve yapmak istediğimiz herşeyi kontrol eden bu iki aleti anakarta bağlayan yuva burasıdır. Bu aygıtlar ayrıca USB portu üzerinden de bağlanabilmektedir.
2. Paralel Port: Eski bir iletişim birimidir ve yeni nesil bilgisayar anakartlarında kullanılmamaya başlanmaktadır. Çok küçük veri transfer hızlarıyla (Baud rate) çalışmaktadırlar.
3. Seri Port: RS232 olarak ta adlandırılabile bu port’ta eski bir bağlantı arabirimidir ve yine paralele port gibi yeni nesil kartlarda kullanılmamaya başlanmaktadır. Seri protta veri transferi RX ve TX olarak adlandırılan iki bacak vasıtasıyla iletilmektedir.
4. USB Portu: Yeni nesil iletişim teknolojisi olarak kullanılan USB 480Mbit/Saniye veri transfer hızına ulaşmaktadır. Bağlantı kablo sayısının az olması ve ergonomik bir bağlantı yapısıyla hemen hemen tüm aletler artık bu arabirimi desteklemektedirler. Bilgisayardaki usb port sayısı kasa önü ile birlikte genellikle 4 taneden fazladır.
5. Ethernet Portu: Resimde gözüken en üstteki port RJ 45 olarak adlandırılan ethernet portudur ve bilgisayarın ağ ile bağlantılı olmasını ve internete bağlanmasını sağlamaktadır.10 pinli olan bu konnektör telefon kablosunun uç yapısına bezmektedir.
6. Ses Portları: Bilgisayardaki sesli verileri işleyen ses kartının çıkış portlarıdır. Hoparlörler bu soketlere bağlanırlar. 5+1, 2+1. 7+1 gibi formatları destekleyen türleri bulunmaktadır.
Tüm bu port ve parçaların haricinde anakart üstünde bios adı verilen ve anakartın özelliklerini ve çalışma ayarlarını belirleyen ve bilgisayardan ayarlanabilen entegreler bulunmaktadır. İşlemciler overclock yaparken veya kart üzerindeki sabit bazı ayarları değiştirirken bios yeniden ayarlanmalıdır. Bios haricinde çeşitli görevleri olan birçok entegre ve harici elektronik aygıt’ta, anakartın bir düzen içinde olmasını ve diğer donanımlar ile uyum içinde çalışmasını sağlamaktadır.

Welcome to the updated and revamped Hardware 2.0 “Very Best Kit List” for Nov/Dec 09, the last such list for 2009. Here I’ve put together a list of the best high-end and mid-range and budget components currently available. So if you’re thinking of buying, building or even upgrading a PC, this list is a must-read for you!

See also my Holiday Gift Guide 2009 for even more cool kit! 

This time around sees the addition of several new categories, such as netbooks, notebooks, all-in-one PCs, and wireless routers. I’ve also added new products to some of the existing categories too.

These components are on this list because I firmly believe them to be the best either in terms of performance or price – although I’m ready to admit, as always, that there’s room for debate and some choices “go with the gut” more than others.

NOTE: Each time I come out with a list of kit I always end up fielding a few emails and comments from people wondering if companies have “bought” space on the list. Let me tell you now that the only way for a product to get on this list is to be the best – period. Manufacturers, vendors and PR companies have zero influence over this or any other recommendation that I make.

Final note: All prices are approximate … shop around for the best deals!
