Installation Guide

Terminal basics

Kext list

Install a kernel:

CODE
sudo cp /Users/<username>/Downloads/<kernelname> /<kernelname>
       sudo chown root:wheel /<kernelname>
       sudo chmod 644 /<kernelname>


Install a kext:

drag and drop the .kext into the /System/Library/Extensions/ folder, click "authenticate" if it asks you to. Type your password, then open a terminal and type:

CODE
sudo chown -R root:wheel /System/Library/Extensions/<kextname>.kext
    sudo chmod -R 755 /System/Library/Extensions/<kextname>.kext


Add a vendor/device ID combo into a plist:

First you must go *into* the kext, as kexts are merely folders containing other things

You can cd into the kext directory, and then deeper into the Contents directory, to be in the same directory as the Info.plist. For the purpose of explanation, we'll go into the NVDAResman.kext.
CODE
cd /System/Library/Extensions/NVDAResman.kext/Contents/


If you were to cat the the Info.plist then you would see the following: (notice in hot pink the list of vendor/device ID combos that this device supports.)

We can take a look at the PCI Database to find out information about the first one in the list (again, as an example) 0x011010de . Also, note the key that these IDs are found under, IOPCIPrimaryMatch. Ignore the 0x, this just signifies it's a hex code, the first four after the hex are 0110, this is a device id, and the 10de is the vendor ID. More information on the specifics can be found at Wikipedia. Basically, the device/vendor ID combination is very specific to that one device, and every PCI device (meaning a device that uses a PCI bus, not just "PCI" specifically). Section 2A of this page describes how you can find these IDs under Linux or Windows. What we are doing by editing these plists are forcing the PCI bus to match ( IOPCIPrimaryMatch ) against the hardcoded IDs on the device.

Usually all that's required for these pre-existing kernel extensions to act as a driver for normal PC hardware is for the device/vendor ID combo to be added to the requisite kext's info.plist, and sometimes an injector. B166ER shows some of the details about adding in Nvidia driver functionality using this exact explained method in this topic.
