I've no relevant experience to help with that. The only late model BIOS modding I've done was to add NVME support to a P8Z68-V board following a tutorial on the Winraid forum. But perhaps another member who is more familiar with adding CPU support for late UEFI BIOS can chime in?

Hope so

According to this:

The Intel ME is indeed in the PCH, so there is nothing I can do at EEPROM level.
The guy at Win-Raid is damn wrong.

Is there someone here that can help?

If someone can send me a bios dump of a Z97 Pro motherboard would be great.

Maybe try this... https://rog-forum.asus.com/t5/downloads-for-m … x99/td-p/853082

Thanks
I have already this
The PCH is in protection mode, it shuts down after 30 minutes.
I lost all original bios data (uuid, me, serial…), I am trying everything

From my limited experience, the ME is in the BIOS chip, I think one option would be a CH341A and a clamp to program the entire chip, it is possible that a software update does not program BIOS + ME.
Another option would be to look for the Intel FPT version that works with that chipset and find out what version of ME corresponds to that motherboard, with FPT you can program the ME from Windows, as long as the flash is unlocked.
The CH341A path requires extracting the BIOS body from the .CAP file because with this extension, if it is an Aptio IV or V BIOS, it could be easy to do it with UEFITool (https://github.com/LongSoft/UEFITool) extracting the BIOS body. On the Winraid forum, there are many threads dedicated to these things. The CH341A option is the fastest, you just have to be careful with the chip voltage and the voltage supplied by the programmer you use, on the CH341A black, you should make a small modification for most of the chips working at 3.3v.
Good luck.

Thanks I already assessed all of this with both a ch341a and a Xgecu t48.

The PCH is in recovery mode.
