[REQUEST] Dell 7080 Micro unlock bios to support ES CPU

[singsooo]

I am honored to find this forum. I am a novice.
I am going to build a Hackintosh. I bought a Dell 7080 Micro (7080mff), and then purchased a CPU numbered qtb0. But the machine cannot be driven, the screen is black, and the bios cannot be entered. The LED flashes 2 amber and 1 white (CPU error). But the bios contains the microcode A0651 of the ES CPU. I searched a lot of information. Thanks to the experts in this forum. According to the experts, it was found that the stepping was locked. Requesting help, thank you.

Previous/Stock CPU: Intel 10th I9 10900T ES Stepping: p0

OS: Windows 11 Pro (64 bit)

Motherboard: Dell OptiPlex 7080 Micro

Latest version of BIOS from Dell official website. 1.31.0

Current BIOS Installed ：DELL 1.31.0

Problem:

Installed ES CPU, no display. Cannot enter bios. LED flashes 2 amber 1 white. Fans are spinning.

CPU：




Microcode read from BIOS：


I extracted the microcode from the motherboard that can drive this CPU from MSI.
 It is the same as my motherboard. But Dell cannot drive it. It should be the stepping 
problem mentioned by the forum experts. Because the stepping of this es cpu is p0. Thanks again:

Try to flash the oldest version of BIOS.

Thank you very much. I tried version 1.0.7. But it says it cannot be downgraded. I will write it with a programmer later. The bin extracted by EXE contains many files. Is it enough for me to just flash the BIOS file?

You need to downgrade ME-region.

It seems very difficult to downgrade ME. Because the machine does not have a service mode jumper. Thank you, I will go to find information to see how to downgrade ME.
Is there any guide for downgrading ME? Thanks again.

Use compatible version of Intel Flash Image Tool to edit dumped firmware and flash results by a hardware programmer.
