adamsweeting Posted August 30, 2009 Share Posted August 30, 2009 Hey people... Hope someone can help me out, I'm going mad here! I've got a perfect vanilla 10.5.8 running on another harddrive... Got Snow running good on a seperate harddrive, with sound, networking - just can't get hardware accelerated GFX. Installed retail Snow using my 10.5.8 system, EFIv10.1, the usual extensions in /E/E I am not using dsdt.aml.. GFX is working via software rendering, but as soon as I add EFI strings to the boot.plist in /E/E - the system boots, but I get a black screen. I know it's running coz I can get sounds, eject DVD tray via keyboard etc. I've tried using EFI studio, UIinstaller, copying the hex from my 10.5.8 system = all don't work. One thing I thought of was that a while ago when there was an issue with mouse jerking when a Quicktime update came out, I flashed my GFX card with a custom ROM that solved it. I don't know if that would be the cause... because it works perfectly with EFI in 10.5.8 I also got the same result adding Natit.kext to /S/L/E Link to comment Share on other sites More sharing options...

adamsweeting Posted August 31, 2009 Author Share Posted August 31, 2009 What's the device ID of your card? Link to comment Share on other sites More sharing options...
adamsweeting Posted August 31, 2009 Author Share Posted August 31, 2009 Solved now. I flashed my GFX with a vanilla ROM from the manufacturers website using nvflash. Then created my own custom EFI string using OSX Tools with DVI / DVI output. All working properly now. Link to comment Share on other sites More sharing options...
