Hi everyone,
I thought I should share my success getting my system up and running. Many thanks to those who kindly provided the stepping stones to this process. The critical step that got me past the dreaded PCI Configuration Begin was a kext called 'AppleUSBXHCI.kext' which I have provided in the zip bundle (called 'kexts.zip').
I will attempt to help anyone I can, but I'm honestly just a trial and error hacker - I don't really fully understand most of this stuff!
My System Specs
Asus Rampage V Extreme
5960x
Titan X
NOTE: I used a Macbook Pro for some of the steps as I have one available to me so this guide assumes you have access to a working Mac/Hackintosh. I also used an SSD drive in a USB3.0 case as the install drive for Yosemite so I could quickly swap the drive between my PC and to my Macbook Pro where necessary.
Method:
1. Using your Mac, download 10.10.5 from Apple App Store. Make a bootable USB using UniBeast method. Name the USB as “USB”
2. Open Terminal. Write
Code:
defaults write com.apple.finder AppleShowAllFiles YES
killall Finder
3. Navigate to /USB/Extra/Extensions and delete all the kexts
4. Navigate to /USB/System/Library/Extensions and delete AppleACPIPlatform.kext and IOPCIFamily.kext
5. The folder titled “5960x test number one” contains some kexts. Using Kext Wizard, install these kexts to /USB/System/Library/Extensions.
6.. Patch the kernel: Open Terminal and enter:
sudo perl -pi -e 's|\x74\x11\x83\xF8\x3C|\x74\x11\x83\xF8\x3F|g' /Volumes/USB/System/Library/Kernels/kernel
8. In Terminal, type:
defaults write com.apple.finder AppleShowAllFiles NO
killall Finder
9. Using Kext Wizard, repair permissions and rebuild system cache. Also Repair Disk Permissions on ‘USB’ using Disk Utility. Also Repair Disk Permissions on ‘USB’ using Disk Utility.
Once completed, connect the USB and Yosemite Drives to your PC.
10. Use the USB drive to boot the system. Use the following boot flags:
-v -f npci=0x2000 kext-dev-mode=1 nv_disable=1 debug=0x14e
11. Install Yosemite. On completion of installation, DO NOT boot into Yosemite. Boot your PC to the BIOS and hard shut down from there. When PC is off, remove your YOSEMITE drive and plug it into your Mac.
12. Patch the kernel on the Yosemite drive: Open Terminal and enter:
sudo perl -pi -e 's|\x74\x11\x83\xF8\x3C|\x74\x11\x83\xF8\x3F|g' /Volumes/Yosemite/System/Library/Kernels/kernel
13. Using Kext Wizard, install the kexts from folder “5960x test number one” AND the kext called ‘AppleUSBXHCI.kext’ into /Yosemite/System/Library/Extensions
THE ‘AppleUSBXHCI.kext’ IS WHAT GOT ME PAST THE PCI CONFIGURATION BEGIN
14. Using Kext Wizard, repair permissions and rebuild system cache. Also Repair Disk Permissions on ‘Yosemite’ using Disk Utility.
15. Connect ‘Yosemite’ to your PC. Boot the system from USB using the same kernel flags as in step 10, but boot into Yosemite. It’s time to install boot loader onto Yosemite SSD.
18. Post installation: Download nVidia’s laters web drivers. (apparently, from here you can use Clover bootloader and Clover Configurator but I just stuck with Chimera as I’m a bit too lazy to figure out Clover at the moment).
19. Install nVidia’s web drivers and reboot in your Yosemite drive. This time, use the following kernel flags:
npci=0x2000 kext-dev-mode=1 PCIRootUID=1 nvda_drv=1 debug=0x14e
20. Use MultiBeast for post-installation. Edit the boot.plist to enter the relevant boot flags etc.
That’s it - you should have a working 10.10.5 Yosemite installation.
Good luck!
Jezza.
