Instead of installing that kext, setting HotPlug to disabled in the BIOS for your boot drive's SATA port would achieve the same functional result (OS X sees the disk as a internal drive and does not give it a orange ejectable icon). Showing "C600/X79 Series Chipset" in System Information is purely cosmetic and has absolutely no effect on device function. I prefer not to install this kext because I use the Intel and ASMedia HotPlug functionality on my HotSwap drive bays on the front of my case. Installing that kext would kill HotSwap for all Intel SATA ports. 3rd Party SATA kext would kill HotSwap for ASMedia ports. Just set the BIOS correctly and those kexts aren't needed. I will add a not about this in the guide.
