• Don't waste your money on 4 GB of RAM. You won't be able to use it all with Windows XP or Vista 32bits...

    "To address 4GB of memory you need 32 bits of address bus. (Assuming individual bytes are addressable.) This gives us a problem - the same problem that IBM faced when designing the original PC. You tend to want to have more than just memory in a computer - you need things like graphics cards and hard disks to be accessible to the computer in order for it to be able to use them. So just as the original PC had to carve up the 8086's 1MB addressing range into memory (640K) and 'other' (384K), the same problem exists today if you want to fit memory and devices into a 32-bit address range: not all of the available 4GB of address space can be given over to memory."

    Installing the ventilator: Attention, with the kit of my brother (bought on www.ebay.de ) we receive a SANFU radiator with a Paps ventilator mounted on it. After installing everything, we try the system: 65°C and the system reboot (35°C in room)....in fact the ventilator was extracting air and not pushing fresh air on the radiator. I reversed the air flow and as a result we get 52°C even in BURN mode....(True XP2800+ with an Innovatek cool 3.0)

    • A must for ears, so quiet and so easy to install (only if you reduce voltage of fans from 12V to 5V as on PC2).
    • I recommend you a middle or big tower to install everything inside (as on PC1)
    • I recommend you to choose the smallest radiator available (the senfu on PC1 provide good performance at a noise level you can not hear!!!!)
    • Expensive? yes¨but:
      1. You can use part during years...You must admit that this is not the case with your air cooling radiator. For example: forget you Alpha pal 6035 with your latest XP 3000, it is only validated till 1500MHz, it cost me alone 50â?¬
      2. You can choose a less expensive radiator, or buy an old one from an old car, but you will have to cleaned it properly.
      3. You do not need 2 or 3 ventilators, one is enough.
    • Maintenance? every 6 months check the coolant.

  • à Mon PC de 1999

    En février 99, après avoir lu un article sur www.kikumaru.jp qui relatait la possibilité de transformer n&39;importe quel Celeron Slot1 en Bi-proc en réactivant l&39;APIC responsable du SMP. Je décidais d&39;acheter deux Celeron slot 1 300A et de les modifier. Mauvaise idée, car j&39;ai surestimé mes capacités de soudure en ultra-cms. www.msi.comà eut la bonne Idée de fabriquer des adaptateurs MSI MS-6905 compatible Bi-proc mais non disponible en France à l&39;époque.à Unà mois et 330 francs plus tard, je reçois d&39;Allemagne les deux précieuses pièces (merci www.citosoft.com et MSI Allemagne (quel idiot ces Français, ZUT à MSI France et MSI Angleterre !), le temps de vendre mes 300A slot 1 et de racheter des PPGA 370 et NT4 en multi-processing me voila. Tout ça pour vous dire que il est vrai que selon les applications, le gain de performances n&39;est pas stupéfiant (des fois 90% ;-)) mais que le sentiment de puissance est bien la, NT ne semble plus d&39;essoufler quel que soit le nombre d&39;applications ouvertes, seul le disque dur reste la ressource critique qui freine les performances de l&39;ensemble (IBM UDMA 7200 tr/min). Toute les applications semblent bénéficier dans une certaine mesure de ce deuxième coeur d&39;après mes observations.

    La facture s&39;élève à (Février 99)

    1 DFI P2XBL/D 1154 FRF
    2 Celeron PPGA 300A 2x 470 FRF
    2 Adaptateurs MSI 6905 (ppga->slot1)330 FRF avec le port
    2 ventilateurs STANDARD 2x 60 FRF
    ce qui restait le prix d&39;un P2 300 avec 1 carte mère.
     2544 FRF

    Aujourd&39;hui, une Abit BP6 et le tour est joué (1140 FRF +2 cpu).

    Tenter donc l&39;aventure si vos besoins en calculs pure sont important, c&39;est la meilleur affaire de la décennie et Intel ne referra pas deux fois la même erreur.

  • I've made many errors when building my NAS server, and
    this  force me to forget using SUN Zeta File System, at least
    for this year...In fact I have decide to build a NAS before
    even knowing the existence of ZFS, and bought following
    hardware components:
    • 1 Promise Supertrak EX8350 with 8 SATA2 3GB port (RAID6)
    • The cheapest integrated mainboard available: NFORCE4 IGP
    • AMD64 3000+
      I took me half a day to update both mainboard (in order to use the Promise EX8350 PCI e4X in the PCI e 16X port) and controller bios (support of RAID6)! The crazy process of updating BIOS and firmware with a floppy disk has still not disappear. The second issue was also to create a floppy disk on a system without any OS.

    The solution come of course from Knoppix. I was able to find old DOS floppy disk images at www.bootdisk.com: all DOS and Windows version are available there. I quickly boot my disk less machine Knoppix and format a new floppy:
    # fdformat /dev/fd0

    and extract the boot image by typing:
    # dd if=bootdisk.img of=/dev/fd0 bs=1440k
    This has permit me to flash the mainboard with the latest ASS bios available (1001) and the Promise controller.

    Ive contact Promise support 2 times  (Europe AND USA), the response is below:

    So if You ever want to build a NAS powered by a Solaris flavor, first consult the Hardware Compatibility List (HCL), and avoid Promise Technology. I've found that all others main manufacturer like Adaptec and ARECA provide Solaris drivers (HERE) even if it they are quite old (middle of 2005).

    Ive also tried some Solaris flavor which I can definitely recommend You, if You decide  to play with ZFS:
    Both version both seem not to use OpenSolaris Nevada build 44,  so I was not able to play with RAIDZ2 (simulate a RAID6 array)

    A replicated RAID-Z configuration can now have either single- or
    double-parity, which means that one or two device failures can be sustained
    respectively, without any data loss. You can specify the raidz2 keyword for a double-parity RAID-Z
    configuration. Or, you can specify the raidz or raidz1 keyword for a single-parity RAID-Z

    I've also tried Solaris Express 10 (Live CD) which is available also for free (non commercial use), but I was really not convince by the desktop, and hardware was not better recognized.
    What can also stop You from using ZFS is the encryption subproject which has not deliver yet, and the fact that the only supported pool share is NFS (Windows support it with "Windows Services for UNIX version" 300Mb), Samba export still being in development.

    This give me 2 options:  use either a Windows or Linux operating system.Windows has a major advantage by having all drivers support (Cool and Quiet, Nforce4 chipset, Promise driver and management console), but all insecurities and the fully fledged desktop is NOT needed on a true file server. Linux on the other side has also all drivers available (except Promise WebPam management console), and is a lot more modulable: I can remove all functionalities not needed: no FTP, no desktop, no HTTP daemon,... Samba, ssh2 and ReiserFS is all I need!

    I  may choose for the job:
    • OpenSuse 10.1 since I am using SuSE since 3 years  or
    • Free BSD, a leader in stability and securities in the Linux world.
    Right now, I've put 5 disks of 320 GB in a RAID5 logical array, the initialization of 1.2TB  took 18 hours!
    Promise Ex8350 initializing the NAS

    This box has 14 Sata Port and I've add old disk full of data 300GB and  160GB.and 8 USB port (+ 2 Maxtor 300GB USB disk).

    wattage controler checking power comsumption of NAS The power consumption is quite high not only because of all hard disks (15 Watts * 7 = 105), but also because of the AMD64 (95 Watts at 1800MHz and 63 Watts at 800MHz when Cool'nQuiet is active). The promise Intel IIOP cpu is also sucking energy. Without it into he box, total power consumption was below 100 Watts, with 150 Watts!

    In order to better tune the box for power consumption (down clocking, reduce main voltage of CPU core), I've bought a cheap Wattage controller (7 euro), left is the NAS running during init of the array without Cool and Quiet

  • Just got my order of three Raspberry Pi 2!. Compared to the Raspberry Pi 1 it has:

    • A 900MHz quad-core ARM Cortex-A7 CPU
    • 1GB RAM

    Like the (Pi 1) Model B+, it also has:

    • 4 USB ports
    • 40 GPIO pins
    • Full HDMI port
    • Ethernet port
    • Combined 3.5mm audio jack and composite video
    • Camera interface (CSI)
    • Display interface (DSI)
    • Micro SD card slot
    • VideoCore IV 3D graphics core

    Because it has an ARMv7 processor, it can run the full range of ARM GNU/Linux distributions, including Snappy Ubuntu Core, as well as Microsoft Windows 10! The Raspberry Pi 2 has an identical form factor to the previous (Pi 1) Model B+ and has complete compatibility with Raspberry Pi 1.

    Some notes about my experience using the Raspberry Pi model B…and you get it running Linux Debian on it!

    The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming.


    We don’t think that the Raspberry Pi is a fix to all of the world’s computing issues; we do believe that we can be a catalyst. We want to see cheap, accessible, programmable computers everywhere; we actively encourage other companies to clone what we’re doing. We want to break the paradigm where without spending hundreds of pounds on a PC, families can’t use the internet. We want owning a truly personal computer to be normal for children. We think that 2012 is going to be a very exciting year. [About Raspberry PI]
