Hello there.

I need some help with Rebar enabling on my system. I using ASrock Z170 Extreme4 motherboard.
Already figure out how to turn on hidden 4G decod command is setup_var 0x387 0x1
And add FPS module
Also done with patching.
But not doing DSDT Patching because think its is not needed.
So, question is how to flash my modded BIOS?)
