Thank you @joeyd for this detailed tutorial, out of curiosity when I run:
$ ./intelmetool -s
I get the following output:
Bad news, you have a QM77 Express Chipset LPC Controller so you have ME hardware on board and you can't control or disable it, continuing...
Error mapping physical memory 0x0000004275159040 [0x4000] ERRNO=1 Operation not permitted
Could not map MEI PCI device memory
Any idea what this is about and how to address it?
Sorry for the late reply, I somehow overlooked your comment.
Best place to get feedback on that problem is either via the me_cleaner website. If it's not addressed in one of the issues, it might end up needing you to open a github issue for it. For a lot of the problems I ran into I got a lot of help on the coreboot irc, you can reach it by clicking on the diagonal banner in the top right corner when you go to https://www.coreboot.org.
