This is a hard one
IŽve tried several different methods to modify the bios and they have all failed.
It seems that there are some kind of special checksum or encryption which prevents AGESA from loading if the microcode is changed.
This does not seem to be any "standard" feature by AMI so it will be hard to figure out.
