Quick reply since I’m at work, it seems to be an AMI Aptio 5 based firmware, I have yet to look into those, but I’ll probably be looking at one tonight (say… 9h from now) so if I am confident that I can help, I will.
In any case, look into these, they’re guides that should come in handy:
Also, what you posted, that results20 archive, is useful 
, for example:
- The “x64_All_regions_15.0.1.1347.bin” file contains the whole content of your flash chip, if anything went wrong it could be used to restore it to a sane state.
- “x64_bios-region_15.0.1.1347.bin” is the file to be working with, after modifications a similar one would be flashed using FPT (e.g.,
fptw -bios -f modified_file.bin), and you can find that tool in the this thread, at the C2 section: Intel (Converged Security) Management Engine: Drivers, Firmware and Tools (2-15)
That’s all for now, if you do modifications yourself and you want it to be checked I’m sure if you post the modified file here someone would.
