`SAT0` patch fixes potential SATA compatibility issues \(untested\). `HDEF` is checked by `AppleHDAController` to identify a controller as "not GFX." The `NTFY` and `RWAK` patches are to [fix TB3 hotplugging](thunderbolt-3-fix.md#hotplug-event). The two patches to rename `TBDU.XHC` to `TBDU.XHC2` are required for [TB3 companion ports](thunderbolt-3-fix.md#usb-companion-device) because they require a unique device name and `XHC` is already taken by the PCH XHCI controller. The `XHC.GPEH` patch redirects the USB hotplug events from the original `SB.PCI0.XHC` device \(which we disable in a custom SSDT\) to our port-fixed `SB.PCI0.XHC1` device. Finally we disable the `PNP0C09` device which is recognized as the embedded-controller by OSX. It has to be disabled because the NUC has a "virtual" EC that ignores reads/writes to it and this confuses OSX \(for example, if it sees there's an EC, it will try to write sleep/wake info to it\).

It has to be disabled because the NUC has a "virtual" EC that ignores reads/writes to it and this confuses OSX \(for example, if it sees there's an EC, it will try to write sleep/wake info to it\). However, to enable USB power management, we still rename `H_EC` to `EC` even though we do not use the EC. The power management kext does not actually do anything hardware-wise, but it does set static limits for the USB controller to use. The `HS09._UPC` change allows us to redefine the `_UPC` method in the SDST in order for OSX to recogize the Wifi/BT card as internal \(otherwise the port does not show up\). Finally, the `GFX0` to `IGPU` patch allows the graphics power management drivers to load for the Intel iGPU.

The alcid argument is for AppleALC for our [HDA fix](hda-fix.md). Hiberation is not implemented so we make sure we do not accidently trip it. XMP detection is only useful for people who overclock their RAM.

The first `device-id` patch chages the Vega M to be recognized as a Baffin GPU so the graphics accelerator can be enabled. The `name` patch changes the device name for the SD card reader so it can be recognized by `AppleSDHC`. The second `device-id` patch makes AppleLPC get recognized on the LPC device \(the driver does some non-critical power management\).
