fighterhawk Posted September 28, 2009 Share Posted September 28, 2009 I installed snow leopard and then used this in the chameleon rc3 to get the card detected <key>GraphicsEnabler</key> <string>Yes</string> however I can't seem to change the resolution and when i tried inserting an EFI string using osx86tools i ended up with a blank screen once the os loads. Am I missing an important step somewhere? Link to comment https://www.insanelymac.com/forum/topic/189270-qeciresolution-for-8600gt-512mb-on-snow-leopard/ Share on other sites More sharing options...
joamateo Posted September 28, 2009 Share Posted September 28, 2009 Hi, It looks like you are doing it correct, I have the same problem. I have been looking at different forums and tried to add the EFI string for my model (8600GTS 512mb) and the 8600GT 512 (the one working on my 10.5.7). I have used EFI, osx86 tools, manually... and no luck, as you said loads ok (grey apple logo) and then black screen. If you find a solution pls post it here. I have only 2 problems with leopard (vainilla, original snow DVD) sound and graphic card. I know the sound would not be too difficult but I do want to have the graphics fix first as it is the most important thing for performance. Right now the graphic shows 32mb VRAM. Good luck!!

subliminal tone Posted September 28, 2009 Share Posted September 28, 2009 Seems like a wrong nvcap settings. Try with Universal OSx86 Installer. Apply EFI string for cideo card => dont choose your card from drop down menu, on a very bottom of menu you will find custom settings => write your card name (nVidia 8600GTS 512Mb) => Choose ram (512) => then choose right Nvcap settings for your card (DVI/DVI, VGA/DVI or DVI/VGA).

joamateo Posted September 28, 2009 Share Posted September 28, 2009 Hi, I read the instructions and I thought that would solve my issue, but not luck I still get the same black screen after the gray screen (apple logo). Any ideas? At least the solution provided was totally different!! Thanks for trying! By the way this is the boot.plist i have now (not working) <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Graphics Mode</key> <string></string> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string>None</string> <key>device-properties</key> <string>6c0200000100000001000000600200000d00000002010c00d041030a000000000101060000010 101060000007fff04000e0000004e00560050004d0000002000000001000000000000000000000000 000000000000000000000000000000220000005600520041004d002c0074006f00740061006c00730 069007a006500000008000000000000201c0000006400650076006900630065005f00740079007000 650000000f0000004e5644412c506172656e740e0000006e0061006d00650000000b0000006469737 06c617922000000400030002c006400650076006900630065005f00740079007000650000000b0000 00646973706c617922000000400031002c006400650076006900630065005f0074007900700065000 0000b000000646973706c6179100000006d006f00640065006c0000001a0000006e56696469612047 65466f726365203836303047545320000000400031002c0063006f006d00700061007400690062006 c00650000000e0000004e5644412c4e564d616314000000400030002c006e0061006d006500000012 0000004e5644412c446973706c61792d4114000000400031002c006e0061006d00650000001200000 04e5644412c446973706c61792d4220000000400030002c0063006f006d0070006100740069006200 6c00650000000e0000004e5644412c4e564d6163100000004e0056004300410050000000180000000 4000000000003000c00000000000007000000001e00000072006f006d002d00720065007600690073 0069006f006e0000002e0000006e5669646961204765466f7263652038363030475453204f70656e4 74c20456e67696e65205b4546495d</string> </dict> </plist> And this is the plain one that works fine: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string></string> </dict> </plist> Link to comment https://www.insanelymac.com/forum/topic/189270-qeciresolution-for-8600gt-512mb-on-snow-leopard/#findComment-1283394 Share on other sites More sharing options...

everdone Posted March 2, 2010 Share Posted March 2, 2010 There are two possible com.apple.Boot.plist. The original one is in Library/Preferences/Systemconfiguration and is the one that OS86tools and EFIStudio modify. With a Chameleon bootloader there can also be a boot.plist in /Extra folder. If there is one in that folder, Chameleon will use that one during boot. That boot.plist should contain the GraphicsEnabler key or the device_propertities key if using EFI string for video. Do not use both GraphicsEnabler and EFI string for video at the same time. If you have a boot.plist in /Extra and have used OS86tools to create an EFI string and it is in the L/P/Sc folder, you can copy and paste the string from that plist to the one in /Extra (be sure to include the device_properties key).
