The Intel Management Engine ('IME' or 'ME') is an out-of-band co-processor integrated in all post-2006 Intel-CPU-based PCs. It has full network and memory access and runs proprietary, signed, closed-source software at ring -2, independently of the BIOS, main CPU and platform operating system - a fact which many regard as an unacceptable security risk (particularly given that at least one remotely exploitable security hole has already been reported).

In this mini-guide, I'll run through the process of disabling the IME on your target PC.

Apparently, the IME co-processor runs... MINIX 3. That is incredibly fascinating. This means every post-2006 Intel PC runs MINIX.

It doesn't help that AMD changed the name twice. First to PSP (Platform Security Processor) and now to "Secure Processor".

According to this article, the first in-the-wild PSP cores back in 2014 were 32-bit ARM Cortex-A5 cores:

...and here are some more recent links about it:
