Hey all. Sorry for all the questions! But I have one about the "DSDT Patch" im wondering what exactly the deal is with it? Is it only for those who's motherboards won't allow it to install?

DSDT patching is like rearranging the hardware info table in pc's BIOS so OSX kernel can get it.(like..O.k I get it!)
So you can use less custom kext . Less custom kexts = more original kexts = more like Mac = . This has lead to a bios patching for hackintosh that result a custom bios (--> Gigabyte mobo).
Detail about DSDT can be read here.

Actually the other way around. BIOS modding led to DSDT patching . Work like this was way before Gigabyte BIOS or Hackint0sh's.
