I've installed Mavericks successfully using clover UEFI on a machine with these specs. Asus p8h61-m le (with patched BIOS from biosrepo) i5 2400 (Sandy) Geforce GT210 Thought it was all %100 but after rebooting a few times, boot got stuck at 'P-state error 18' and KPs soon after due to AppleCPUPowerManagement.kext Strange thing is, if I leave it boot cycling, it will eventually boot. Sometimes first go, other times after 30 or more tries. I tried enabling C-states and P-states via clover but no change. (I'm not sure the P-State error actually has anything to do with the KP) I also tried the ssdtPRGen script and used that with clover but still no change. I'm not sure where to go from here. Can someone please point me in the right direction???
TijuanaKez replied to bcc9's topic in ATiHope this isn't too off topic but trying to get 10.7 to recognise both DVI ports on a sapphire 6870 using this procedure but I've hit a wall. The default frame buffer for this card is Duckweed which works with only one DVI port. The duckweed port table lists 2 x DP, 1 x HDMI and 1 x DVI which is not going to work as the card has 1 x DP and 2 x DVI (1 single, 1 dual). Both DVI ports work with GraphicsEnabler=No but DVD Player and Ableton crash without correct frame buffer loaded and ableton crashing is not an option for me.

GPU-Z I've tried just changing the connector type in the first line to 0004 instead of 0400 I've tried copying the single link DVI code from port 3 to port 0. But I have been just hex editing ATI6000Controller and booting 64bit.... will this not work? I'm unclear on instructions for 64bit. Seeing as none of the ATI6000 series FrameBuffers enable the dual-link DVI I have nothing to copy and paste. I'm hoping I have enough information from radeon_bios_decode and IOReigstryExplorer to get it working anyway, just a bit unsure how to implement it. Any help would be greatly appreciated. There are quite a few people struggling with this card and getting a compatible personality would close a lot of threads.
