This is a new thread to remove the clutter from my old one, which can be found here:


This is for new builds utilizing a new technique which does not "scrub" the management engine, but turns it off via an issued command and forces execution of it's code to halt. If you need more technical details, all I can say is it's a simple property change to make the documented "ME Temporary Disable" mode permanent. (US Government targets use this mode in it's HAP form, you can trust it). You can probably figure out what I did by dissecting the roms, but since some vendors seems to be adapting to my changes, I won't be saying more.

Scrubbing the rom entirely just got too hard, but this should be functionally the same.

You can get stable/approved builds for some boards here. It's really just the Taichi right now. (prefix "ZxTC")


Experimental boards (basically just the Z390 Phantom Gaming X) can be found here. Support for them may/may not continue depending on test results. They may also have a slight brick risk:


Important: Follow the instructions below. Make sure you flash the absolute STOCK bios before using the zip file mod!

Instructions:

Step 1: Flash your stock firmware image, same version as the one you want to disable ME on.

Step 2: Take note of your settings.

Step 3: Restore BIOS defaults (or get as close as possible if you need some obscure setting for booting, that is ok).

Step 4: Boot Windows, download the zip for your version.

Step 5: Extract the zip file. Note the directory path.

Step 6: Open an Admin CMD prompt.

Step 7: Cd to the directory. (ie cd C:\path\to\directory)

Step 8: type "flashme" and hit enter.

Step 9: Let the flash complete and shutdown the computer.

Step 10. Power on and enter bios. Reset to defaults one last time. (essential!) Now, reboot and set your settings how you want them.

Step 11: Boot to Windows and confirm management engine is disabled (If you don't have any "management engine" device in device manager (usually an Unknown or System Device), you have it disabled).

Step 12: Profit.

Old thread reported for closure. Please issue reports on the new builds here. I also take requests for new boards and reports of new firmware versions on supported boards in this thread... But to limit my level of insanity, I'm currently only working with ASRock and GIGABYTE boards (they are the ones I am most familiar with right now).

Thank you so much for your hard work Z39PGX110 worked beautifully!

We have one failure report on the Z370 Taichi v4.10, so be cautious around that one. Dual bios on the taichi should keep you safe, but... just a PSA.

Asrock has removed the Z370 Taichi v4.10 Bios.
So maybe the problem was related to the bios itselfe and not your Mod. Just to let you all know.

May take a bit longer, as said in my profile, spent this weekend in the ER (am fine, just a scare) and it greatly limited me.

Will try to work on it this week.
