You dont need to use pmpatch. You must do this:

1. backup: afuwinx64 extracted-bios.bin /o

2. apply the changes to extracted-bios.bin file. Eg: change the microcode
3. apply: afuwinx64 extracted-bios.bin /gan

HI Florin9doi,

The instructions that you are giving are confusing to me because I have never tweaked a bios. I have a .CAP bios not a BIN. Are you talking about modifying with a command line?
Man , 7 years as an MVP and I don't understand BIOS tweaking .

Thanks for your patience.

At first step you backup the current bios. So the file will be created with the given name of your choice. I prefer .rom extension for example. So do not bother for the file name.

Sorry I haven't started a topic about that method earlier, as I have planned like 2 weeks ago. Will do it ASAP.

This dump/modify/flash method was tested on variety of boards, but there are reports, that sometimes it doesn't changes anything (BIOS remains untouched after "successful" flashing attempt), and in rare cases it can also brick the board, so please try it as a last resort and on your own risk.

/GAN is not needed only on boards that have no SMI and BIOS locks, which are very rare now.
AFU is not as reliable as Intel FPT or flashrom, but it's the only flasher that can bypass security verification issues on modern AMI Aptio-based boards.

Hi CodeRush,

I'm really confused.

Is it possible to have the bios that Virtualfred modded (Post #4) to load without security warning? I tried to mod using the command line PMPatch Z87A.CAP Z87APATCHED.C
AP

So it seems that the biggest issue with modding certain .cap files is the Security Verification or Validation failed problem

Well, I hope that someone can get a functionnal tool to fix this.

Hi Fernando,

VirtualFred did remod with tool and Security Verification or Validation failed was still showing.

No,

He pm'd me and had re moded bios. It did not work.

Hi Fernando,

To be frank with you it doesn't really matter anymore because bios has been updated to 1707 version, but FYI he had renamed it Z87A.cap. I tried to rename the mofified version but to no avail.
