macbrush Posted December 11, 2012 Share Posted December 11, 2012 I just upgraded my q9450 hack to i7 3770 on a Gigabyte Z77-DS3H board. The process was pretty painless, I just removed some unnecessary kexts, set BIOS to boot legacy and then it just works, with one exception; my PCI cards aren't working anymore. I know it is something to do with the PCI-PCIe bridge since Z77 doesn't natively support PCI slots, but I can't seem to find a solution. I have tried setting PCIRootUID=0 to no avail. Any suggestion or pointer would be very much appreciated. Cheers Kenneth Link to comment Share on other sites More sharing options...
macbrush Posted December 11, 2012 Author Share Posted December 11, 2012 I guess I will have to answer my own question. First of all, I apologise since it wasn't really a OS X problem nor BIOS. It was the 8 pin 12V somehow wasn't connected properly. The sitting looked fine, even have power on the firewire devices, but somehow it didn't supply any power to the PCI cards. I had to re-sit it a couple of times to get it working. Link to comment Share on other sites More sharing options...
