HUANANZHI X99-QD4: Success? #395

Closed khankul closed 8 months ago

khankul commented 1 year ago

Since I already used S3TurboTool to flash OC firmware, I decided to stick to it. It uses Intel FPT under the hood. Done on Windows, with occasional help from Debian Live (coreboot utils).

Steps taken:

  1. Use the tool to dump the firmware (Сделать fullbackup)
  2. Run me_cleaner.py -S on the firmware
  3. Use the tool to flash the firmware back (Прошить BIOS)
  4. Shutdown and turn off the power for a few seconds
  5. Reboot into system

intelmetool -m output on Debian:

Bad news, you have a `H87 Express LPC Controller` so you have ME hardware on board and you can't control or disable it, continuing...

Wonder if there's a way to disable Manufacturing Mode.
