Remember: disabling the IME is a completely optional step: proceed entirely at your own risk.

On some (though not many) PCs, the ME is used to initialize or manage certain system peripherals and/or provide silicon workarounds - if that is the case on your target machine, you may lose functionality by disabling it. It may result in your machine becoming 'bricked'. The process involved will require re-flashing your system's BIOS-chip firmware image, and will almost certainly void your system warranty. This combined 'belt-and-braces' approach means that the ME ought to cleanly enter a self-induced null state (after resetting the 30-minute watchdog timer) but, should that not work, it will nevertheless enter a failed state shortly thereafter (as the majority of its core software modules have been purged). removes the vast majority of the ME's software modules (including network stack, RTOS and Java VM), leaving only the essential 'bring up' components (the latter being necessary because, on modern systems, if the IME fails to initialize, either the machine startup will be completely halted at that point, or startup will appear to complete, only for a watchdog timer to reset the whole PC 30 minutes later ).sets the 'High Assurance Program' bit, an ME 'kill switch' that the US government reportedly had incorporated for PCs used in sensitive applications.

This software operates on the firmware stored in your PC's BIOS chip (where the bulk of the ME's code resides), and does two things: To do so, we will use Nicola Corna's me_cleaner. In this mini-guide, I'll run through the process of disabling the IME on your target PC. It has full network and memory access and runs proprietary, signed, closed-source software at ring -3, 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 ). The Intel Management Engine ('IME' or 'ME') is an out-of-band co-processor integrated in all post-2006 Intel-CPU-based PCs.
