This set of patches/makefile can be used to patch your Haswell Gigabyte BRIX DSDT/SSDTs. It relies heavily on already existing laptop DSDT patches at github here: https://github.com/RehabMan/Laptop-DSDT-Patch.. There are also post install scripts that can be used to create and install the kexts the are required for this laptop series.
The current repository actually uses only on-the-fly patches vai config.plist and an additional SSDT, SSDT-HACK.aml.
Please refer to this guide thread on tonymacx86.com for a step-by-step process, feedback, and questions:

add preliminary Broadwell support (not tested)
copy "essential" kexts to EFI/Clover/kexts/Other as part of install_downloads.sh

refactor SSDT-HACK into separate SSDTs
inject graphics with SSDT-IGPU (more flexible and will handle models other than this specific BRIX)

Use Arbitrary injection (new feature in Clover, working with my fixes to Clover v3279+)
use DSDT/Patches for IGPU/HDAU renames (DSDT/Patches faster with my fixes to Clover v3279+)
