jeffffff Posted March 11, 2009 Share Posted March 11, 2009 Hi everyone, I've been trying different installs to get osx running on my pc here at home. the build/components are as follows: GA-ep45-ds4p mobo intel e8400 3 ghz processor ati sapphire 3850 video card 4 gigs g-skill ram sata WD 7200 rpm hard drive sata dvd drive I'm using iatkos 10.5.5 and the particular problem I have doesn't seem to be documented (at least I haven't been able to find it after spending a lot of time googling)... basically, after "successful" installs, whenever I try to start up osx I get about ten seconds of a spinning cursor and the gray apple loading screen followed by a strange-looking corrupted graphics screen and a locked machine. I am able to boot the machine into safe mode successfully but have no idea how to proceed from there to fix whatever issue is occurring. I have attached three images below... the first is the corrupted image upon normal startup, the second is the -v code that appears as close to the lockup as I could photograph and the third is the corrupted and locked-up image after startup in -v mode. Any help you all could provide would be appreciated! I am happy to answer any/all questions as I just want to get this problem solved. Thanks so much for your time!

kulos Posted March 11, 2009 Share Posted March 11, 2009 I'm sorry, but I cant read the text in the middle picture. Can you improve the picture quality?? Did you install any drivers for the ATI card? I would choose as few drivers as possible (only the necessary ones) when installing and add graphics and audio drivers/EFI strings later! kulos Link to comment https://www.insanelymac.com/forum/topic/157241-ga-ep45-ds4p-iatkos-1055-and-unsuccessful-startups/#findComment-1104804 Share on other sites More sharing options...

Re: video drivers... I have installed iatkos with the "Graphics Update" and "ATI HD 2xxx and 3xxxx" options selected, with only the "ATI HD 2xxx and 3xxxx" option selected and with neither selected. I have had similar results in each instance.

jeffffff Posted March 12, 2009 Author Share Posted March 12, 2009 subsequent installs with different options/drivers tried out has led to similar results, though sometimes I get a hanging blue screen, not the corrupted graphics as shown earlier... any suggestions?

jdratlif Posted March 13, 2009 Share Posted March 13, 2009 I recommend deleting (or better moving) all kexts related to ATI drivers until Mac is forced to use the VESA drivers. Then you can try to find a driver that works. Sorry I don't know any of the names. Look for things in the /System/Library/Extensions folder with ATI, Natit, Titan, or Radeon in the names. Move them to a different folder. Then delete /System/Library/Extentions.mkext and reboot.
