    Software defined custom pipeline, card was ahead of its time.

    Really fascinating! I never really understood all of the intricacies of graphics cards, and just how much they've changed over the years!

      When this card was on sale in 1998 there were so many options: S3, Cirrus Logic, SiS, Trident, Permedia, Number 9 etc. And of course 3dfx, ATI, Matrox and nVidia.

    As of current standards, it will be a chip made by SK Hynix. LG Semicon (Lucky + Gold Star) -> Hyundai Electronics (was in the same group as Hyundai Motor) -> Hynix(“Hy”undai Electro”nix”) -> SK Hynix

      I know it has nothing to do with this, but I got a Goldstar microwave, with display and touch buttons, still going strong. It's from the 80s. Older than myself.
      I just wanted to share it, no idea as to why. :)

    Programmable graphics chip before shaders. With just a little bit more performance it could become a real competitor to fixed pipeline chips. I wonder if it would be possible to have more than one DSP on single card and how the performance would scale.

      There are some articles about Mpact 2 chip as early as November 1996 - but the card was on the market in 1998, it was too late and this basically killed the entire company. If drivers would have been ready in late 1996 - it think this card could have been a good competitor for 3dfx Voodoo Rush which was 30% faster but it had compatibility problems with many games and no MPEG2 decoding.

    Wow, an Mpact! Lovely card, I wish I could find one. They never show up for sale, I'm lucky to have my Permedia 2.

      I got this Mpact card by chance. I found it on slot A Athlon K7 850Mhz PC. Didn't knew it was an Mpact, but the digital audio out made me curios enough to extract the card for a further examination...

    Nice! Never heard of this card or company. Looks like it was way better than S3 or Cirrus Logic default video cards that came with new computers sold in 1997/1998. I actually played MDK on a AMD K5 PR200 (133Mhz) + S3 Virge GX 2MB.

    Like a fever dream, I barely remember this era of hardware. I guess PCs were so weak that you needed additional hardware just to watch a DVD. IIRC, 512x384 performed better than 400x300 on the Permedia 2 due to something with the texture memory. I was using D3D wrappers for a lot of things until OpenGL 2.1 started getting used on eveything...maybe the late 2010s? Scitech GLDirect was worth the cost back in the these days of mega janky hardware.

      Yes, back at mid 90s, late 90s you would need a decoder card to play DVDs as a Pentium II at 233 MHz was too weak for that task, however with the Pentium III 500 MHz you would be able to play DVDs by software decoding, with some screen tearing, but also at that time most video cards would start to include dvd acceleration (motion compensation) to help the cpu.

    If I use my Android phone, which is an iQOO Z3, the USB tethering is not working on Windows 2000. How can I fix this in Windows 2000?

    I installed UniATA after adding a second drive as SATA, it directed in VirtualBox. However, when I booted on a real PC again, I still encountered the 0x00007B error.

    • @O_mores
      @O_mores  3 месяца назад

      To resolve the 0x00007B error after installing UniATA, the issue might stem from UniATA not recognizing the specific SATA controller on your newer motherboard. UniATA supports many controllers, but with newer hardware, sometimes the necessary hardware IDs for your SATA controller might not be included in its .inf file.
      You can try adding your SATA controller's hardware ID manually to UniATA's driver .inf file:
      1.Go to Device Manager in Windows and find your SATA controller under "IDE ATA/ATAPI controllers" or "Storage Controllers."
      2.Right-click on it, go to "Properties," then "Details" tab, and select "Hardware Ids" from the dropdown menu.
      3.Copy the hardware IDs listed.
      4.Open the UniATA .inf file (found in the driver package), and add those hardware IDs under the appropriate section.
      5. Reinstall UniATA with this modified .inf file.
      This way, UniATA will recognize your motherboard’s controller, which should help bypass the 0x00007B error.
