  1. ATI HD4850 (Sapphire) in Snow Leopard

    Actually you do have QE/CI enabled System Profiler no longer shows QE/CI information since all Intel CPUs support it.
  2. ATI HD4850 (Sapphire) in Snow Leopard

    You didn't answer my questions Also, make sure you install the 10.6.2 combo update before making the changes.
  3. HD4850 (HDMI/VGA/DVI) on 10.6.2

    Thank you for your answer Alex. The DVI output doesn't work in any resolution and since it works using HDMI->DVI I'm quite sure the problem is the graphics card's driver and not the monitor. If I had the source code of the driver I believe I could fix it. For now I'm indeed happy with the HDMI->DVI cable
  4. ATI HD4850 (Sapphire) in Snow Leopard

    Your device id is 0x94421002 What is the exact model of your graphics card? what are the available video outputs? do you use DVI, HDMI, VGA or DisplayPort? Are you using PC EFI or Chameleon 2.0 RC4? This is the recommended way to get HD4850 (not Sapphire specific) working on SL 10.6.2 assuming you just updated to 10.6.2 using the combo update from Apple site: 1. Download Kext Helper b7 and Kext Utility. 2. Remove ATI4500Controller.kext and ATI4600Controller.kext from System/Library/Extensions. 3. Add LegacyATI4800Controller.kext to Extra/Extensions using Kext Helper b7. 4. Rebuild caches using Kext Utility. 5. Reboot with -v GraphicsEnabler=Yes and if you get kernel panic in ATIRadeonX2000.kext reboot again with -v GraphicsEnabler=Yes -pci1 PciRoot=1 If this doesn't work (please test all outputs before you assume it doesn't) try installing this and then this. Then boot again as described in step 5 above. Good luck!
  5. HD4850 (HDMI/VGA/DVI) on 10.6.2

    Hi all, I have a PowerColor HD4850 512MB card with HDMI, VGA and DVI outputs. My monitor is Dell 2209WA with DVI-D and VGA connections. I installed Snow Leopard 10.6.2, removed 4500/4600 kexts, added legacy4800controller kext, and booted with Chameleon 2.0-RC4 with PciRoot=1 GraphicsEnabler=Yes. * VGA works well (using VGA-VGA). * HDMI works well (using HDMI-DVI). * DVI doesn't work (using DVI-DVI). I get a black screen and the monitor enters power saving mode. I really want to use the DVI output for this monitor. In safe mode all outputs work (without QE/CI of course) so the solution is probably patching ATIRadeonX2000.kext. Is any source code available for this kext? I know there are patched kexts from netkas so it must be possible Other hints on how to get the DVI output working are welcome. Note that I've already read all HD4850 posts in these forums. Thanks, Roee.
