@zaq_hack - What's the issue you're trying to solve? I've been able to get mine functioning from a bricked BIOS, so while I don't know how to change the microcode, I might be able to help you with at least a workaround.

advisoryIDs = "INTEL-SA-00161", "INTEL-SA-00219", "INTEL-SA-00289", "INTEL-SA-00334"

Far as I know, these can only be fixed with new microcode and proper BIOS options.

Interesting. I haven't had that problem, that I know of. May I ask how you can tell, and what are the problems it's causing? I had to flash a generic G7 BIOS on my machine to get it unbricked, and now it thinks it's a G5, so I wonder if some of the issues I'm having could be caused by microcode problems.

Ok friends, there are Eeprom's write protect variables to set 0x00 ...

BIOS platform - AMI Aptio 5

Error 167: Protected Range Registers are currently set by BIOS, preventing flash access.
Please contact the target system BIOS vendor for an option to disable
Protected Range Registers.

FPT Operation Failed.

Variables are :

BIOS Lock VarOffset - 0xA07
FPRR VarOffset - 0x10C1

We cannot write back the bios mod without these modifies, so use RU shell like into these tutorials and set the values to 0x00 :

You'll find under Setup [EC87D643-EBA4-4BB5-A1E5-3F3E36B20DA9] GUID

We have to check too the MEinfo to check the Boot Guard and FPF active ... use this tool and get the verbose log :

[Tip] Use of the Intel MEInfo Tool under Win8.1 RTM
