hey,
here is a link to my modified Maximus ix extreme bios (modified with coffeetime):

M9E

I`m looking for hidden menus (GPU Aperture size setting to be exact) AND the SR-IOV option to be enabled.
also I would like to know if it`s possible to port a bios from M10A (closest z370 board I can think of) for better memory stability.(there are some other settings that doesn`t work properly on my board but they do on a M10A I have tested)
here is the link to M10A bios:
Maximus X Apex

Edit by Fernando: Thread title customized

Use IFRextract and see wot ur bios got about the variables u intend... the rest is ridiculous, im sure that u see a lot of "porting" where ever..
