Captain America Posted May 10, 2012 Share Posted May 10, 2012 So I have an MSI GX740 235-US and when I run the USB, I get stuck on PCI Configuration Begin when I do it with Lion. When I try Snow Leopard, it just reboots. I tried npci=2000 (and 3000) and that didn't do anything. This has been driving me nuts and any help would be much appreciated. Thanks.

Conti Posted May 10, 2012 Share Posted May 10, 2012 Read the troubleshooting section of the guide, it discusses npci flags - but also links to some IOPCIFamily kexts that netkas put together that may help you. Link to comment Share on other sites More sharing options...
Captain America Posted May 11, 2012 Author Share Posted May 11, 2012 Will do. I don't know anything about replacing kexts though. EDIT: Nevermind, I read the Troubleshooting section about it and dropped the files in the folder. Is there anything wrong with the fact that the particular kext didn't already exist? Also, it didn't work when I booted it...still getting stuck on PCI Configuration Begin. EDIT2: Tried the kext on Snow Leopard. Still reboots.

Conti Posted May 11, 2012 Share Posted May 11, 2012 Did you run myfix after adding the extensions to /Extra/Extensions ? Link to comment Share on other sites More sharing options...
Captain America Posted May 11, 2012 Author Share Posted May 11, 2012 Yup. Didn't help. Link to comment Share on other sites More sharing options...
Conti Posted May 12, 2012 Share Posted May 12, 2012 Try to replace AppleACPIPlatform.kext with an older version as well. Link to comment Share on other sites More sharing options...
Captain America Posted May 12, 2012 Author Share Posted May 12, 2012 Alright, I'll give it a shot after work. Thing is though, how do I get it? EDIT: Got it from this site: http://www.osx86.net/view/1481-appleacp ... 0.6.6.html Didn't work still getting the PCI Configuration Begin. EDIT2: I managed to get it working! I used the flags -v -x npci=0x3000 pci=off GraphicsEnabler=No But I have new problems. My trackpad doesn't work, I don't have Wifi or Ethernet drivers, I need the MyHack USB to boot with the flags that I mentioned before. Not only that but no other USB devices work, my disc drive won't open, the graphics are kind of laggy. I think pretty much everything except the operating system itself aren't working. When I try to run MyHack it tells me that it can't be run in safe boot mode. I have so many problems right now its ridiculous. EDIT3: a little hardware background might help you Intel Core i5 450M ATI Mobility Radeon HD 5870 Ralink RT3090 (wifi card) 8GB DDR3 1333MHz Intel HM55 Chipset EDIT 4: Trackpad works now, still no ethernet, sound or wifi. I got it to boot without MyHack by installing Chameleon and editing the plist to add the pci=off (which I think is the reason I can't use my wifi).I tried downloading OS X drivers from RaLink's website but the wireless utility doesn't detect the wifi card probably because PCI is disabled. Other USB devices work now thanks to myfix, disc drive seems to work. Safe mode isn't an issue anymore. But like I just said, I still need: WiFi Ethernet Sound thanks for the help.
