The line-up boasts many firsts for the graphics industry, including a powerful second-generation Unified Shader Architecture (USA), a 512 Mbit memory bus designed for full performance high dynamic range (HDR) rendering, and new Unified Video Decoder (UVD) technology for high-fidelity HD multimedia playback. I am reprogramming Chameleon to add better support for RS880 and RV620 cards.Ĭurrently, the target system is an AMD Mobility board running with Radeon HD Mobility 4250 (9712).Īlso I have been searching high and low for the SharksFB.rtf to add to my kexts because apparently that is what is needed for the Graphics Card I have (HD 3200) not mobility (unless they are the same thing which I dont believe is the case).The ATI Radeon HD 2000 series of products introduces immersive DirectX® 10 gaming enabling the next generation of visual effects at every price point.

The Mobility Radeon HD 3400 is getting old now, and I am having graphics issues even on the latest linux releases. I edited my connector values in the ATIRadeon2600 frame buffer to get the internal LVDS to work (only 16-bit colour depth as I dont know the correct dithering values for my panel).Īlso as my GPU is an ATI Mobility Radeon HD 2600 XT (the same as iMac8,1) my hardware ID is already present in all the required kexts. PD: I use Chameleon with a custom EFI graphics property list based on the EFI values of an iMac8,1. What is clear is that ATIRadeonX2000GA enables the creation of hardware accelerated overlays and is properly creating them but no content is written to such overlays. I suspect that as Apple decided to replace the display detection routines by fixed value tables there is some value that the accelerator requires to properly write the accelerated pixels in the correct memory offset. I did many tests without success, it is pretty complex as acceleration is based on lots of hardware instructions with nearly any open source reference.

So to make these graphics cards work in reasonable useful way in Mac OS X you would have to understand the disassemblies of the hardware acceleration driver components, specially the part that refers to writing rendered pixels to display buffers.

I even managed to check that in fact graphic acceleration works for this graphics cards in Mac OS X 10.6 but for some reason the hardware accelerated surfaces are not written back to the display frame buffer.Ībout flashing an original Mac GPU bios, it might result useless as most of PC versions of this GPUs only have a 64 Kb on-board EPROM while a Mac GPU bios has 128 Kb of size being the last bytes of the bios image the ones that contain the EFI initialization code that makes Mac bios different from PC. The most I have managed to get with one of these cards (ATI Radeon HD 2600 XT) in Mac OS X 10.6 is a fully working frame buffer which gives support for up to two monitors with cloning and desktop expansion modes (no backlight control for my LVDS CCFL backlighted display).

These cards might work properly in Mac OS X 10.5.x with hardware acceleration (GL, QE, CI, and Video) but considering the Mac App Store requires applications to be compiled for Mac OS X 10.6.x as a minimum with no backwards compatibility you will only be able to run outdated versions of most of applications. Of course having only BIOS file you can get its Hardware ID just reading that bios with RBE tool ( under windows).Īnd if I have stated any stupid or uninformed comments please go easy.Īlthough you can comment here, but this topic is not intended for this. You have bios files with card ID and manufacturer description.
