I think a CPU that has no mini PC inside it is much easy to verify, you can try a lot of inputs and see if the output gets weird, I think this technique was used to discover some hidden switches in Intel that the government uses to work around the ME on their own systems.

- simion314 9y agoWhat do you mean the ethernet card triggers changes in Windows instructions? Do you mean it can scan the RAM and do some changes? I am not familiar with how recent hardware works but I would be worried if hardware could scan RAM and edit executable code bypassing the kernel and drivers, so more reasons to get open hardware and drivers.
