whaase Posted February 25, 2013 Share Posted February 25, 2013 I'm going nuts trying to figure this issue out. I've been googling and trying things for 4 days now. I have a Gigabyte GA-H55M-UD2H with a i3 and a Nvidia Geforce 520. I could not use the onboard gfx to install. It froze with every command I could try. I tried using the 520 during the instlall, I could not even get the install to even start. I would get the dreaded PCI Configuration Begin error. So... I put in a 7300GT I had knowing its not 64bit supported, but I was able to install ML. I then shut down, put in my 520 again and tried booting again. Same PCI Configuration Begin error. I've tried every combination of: -x GraphicsEnabler=No and Yes UseKernalCache=Yes and No ncpi=0x2000 and 3000 I can boot my Lion partition with the 520 card in no problem using 32bit mode. What am I missing or doing wrong? Thanks Walter Link to comment Share on other sites More sharing options...

iFIRE Posted February 25, 2013 Share Posted February 25, 2013 Try this, put in your USBInstaller in S/L/E or in ExtraExtensions carpeta sin tà tulo.zip Link to comment Share on other sites More sharing options...
whaase Posted February 25, 2013 Author Share Posted February 25, 2013 Ok, I tried that. I'm still getting the same message. I can usually figure this stuff out on my own but this one has got me stumped Link to comment Share on other sites More sharing options...
iFIRE Posted February 25, 2013 Share Posted February 25, 2013 use this flag: -f -v npci=0x2000 GraphicsEnabler=No UseKernelCache=No Link to comment Share on other sites More sharing options...
whaase Posted February 25, 2013 Author Share Posted February 25, 2013 Ok, I got a bit further. I got it to boot into the installer, I installed ML. I rebooted into the installer, used those flags to boot ML. I get this now... never seen this one lol Link to comment Share on other sites More sharing options...
eep357 Posted February 26, 2013 Share Posted February 26, 2013 You have different versions of same kexts trying to load, these could be from S/L/E, kernel cache and/or Extra/Extensions. Remove all from Extra/Extensions installing to S/L/E instead. Repair permissions and boot using -f at least, if you then get hangup from GPU add -x 1 Link to comment Share on other sites More sharing options...
whaase Posted February 27, 2013 Author Share Posted February 27, 2013 I ended up finding a 520 kext that someone edited. I copied it to the bootloader and drive. Fixed permissions and it booted perfect. What I don't understand is why Lion had no issues? Weird stuff but at least I got it now. Thanks to everyone for your help. Anyone needs the drivers I can link them Link to comment Share on other sites More sharing options...
