FuManchu84 Posted September 5, 2009 Share Posted September 5, 2009 I'm planning to install SL and according to the threads around it should be no problem on my GA-EP35-DS4. The only thing I'm not sure about is my ATI Radeon 2600XT. Is there anyone who had success running SL with this card? There are many people that report bad things about the Radeon 2600 series under SL. So, will it be possible or not? I'm currently running 10.5.8 and this driver. Is there a chance that it also works with SL? Link to comment Share on other sites More sharing options...
errandwolfe Posted September 6, 2009 Share Posted September 6, 2009 To answer your question, I will tell you what I THINK...I would not take this as the final word on the subject... Right now it looks like the ATI series is not supported as far as QE/CI is concerned. You can get it working as far as resolution changes are concerned but to the best of my knowledge there is no support currently for accelerated video and there most likely will not be any support ever for the new OpenCL technologies.

Thanks for the answer, but HOW do I get it working? I'm a little pissed becaus I bought this card (and the rest of my components) to maximize compatibility with OSX (the older Mac Pros had the exact same model). And now SL doesn't support it any more? For Leopard I used the installer (see link above). So I never messed around with EFI strings or something like that. Several guides recommend to use EFI studio to create a GFX string. But the EFI studio I have (V 1.1, I think it's the latest release) only supports some Geforce cards. So did you get your Radeon running under SL and HOW did you do it?

Original Sl support Hd 2600XT, bu the firmware is not the same. Only 48xx series is supported with QE/CI in Snow/Hackintosh. Rare cases of x1950 working are present in the forum. For working with 2600XT in Snow, only resolution change, but not QE/CI, you must put EFIstring for 2400XT in your com.apple.Boot.plist and erase ATIRadeonX2000.kext Giorgio Link to comment Share on other sites More sharing options...
