SeanieB Posted December 12, 2010 Share Posted December 12, 2010 Hi. I upgraded to 10.6.5 because seemingly I couldn't upgrade over 10.6.0 and have working graphics.. It looks like I'm close though. Safeboot can see the info for the GPU, I have Chameleon RC5 installed, graphicsenabler on and my device and vender ID's are in ati4800controller.kext's info.plist. Just to make sure: <key>IOName</key> <string>ATI4800Controller</string> <key>IOPCIMatch</key> <string>0x94421002 0x944a1002</string> ATI Radeon 4850 Series: Chipset Model: ATI Radeon 4850 Series Type: GPU Bus: PCIe Slot: Slot-1 PCIe Lane Width: x16 VRAM (Total): 256 MB Vendor: ATI (0x1002) Device ID: 0x9442 Revision ID: 0x0000 ROM Revision: 113-B7710C-176 EFI Driver Version: 01.00.318 Displays: Display: Resolution: 1400 x 1050 Pixel Depth: 32-Bit Color (ARGB8888) Main Display: Yes Mirror: Off Online: Yes Display Connector: Boot.plist: <dict> <key>EthernetBuiltIn</key> <string>Yes</string> <key>Graphics Mode</key> <string>1680x1050x32</string> <key>GraphicsEnabler</key> <string>Yes</string> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string>arch=x86_64</string> <key>PciRoot</key> <string>1</string> <key>Theme</key> <string>Default</string> <key>Timeout</key> <string>3</string> </dict> Safe boot works, obviously, but if I boot normally when I think it is supposed to change the resolution, it just scrambles the screen. The dongle trick doesn't work here. Anyone have any better ideas? I'm also stuck at 1400x1050, that might just be a restriction of the generic driver. I just noticed - it seems to be detecting 256MB for a 512MB card, my card is a Gigabyte GA-R485ZL-512H. The DEVID's and VEN's match windows' detections. (1002 and 9442). I am not sure how I'd fix that though.

SeanieB Posted December 12, 2010 Author Share Posted December 12, 2010 Strangely, booting it up to Windows and back to OS X seems to have fixed the problem. OS X is also now detecting the right amount of RAM for the card. Must have been some sort of NVRAM setting the CCC on windows cleared out or something, but it's working great now.

TH3L4UGH1NGM4N Posted December 12, 2010 Share Posted December 12, 2010 Well I guess maybe the kexts had to be reloaded on the restart is my best guess but good for you Seanie you got things rolling with your 4850 Link to comment Share on other sites More sharing options...
