Recent (1-2 years?) AMD BIOS supports disabling the Platform Security Processor (their ME equivalent).
I haven't been able to figure out what exactly this means, but it does seem to be disabled after system initialization. Kind of like Intel's HAP bit, except user-settable.
Thanks for that! This is quite relevant to me right now as I'm thinking about my next upgrade. Obviously, I'd prefer to buy AMD, especially if this disable switch is legit. But grotesquely, I'm still considering going with Intel, because at least I know I can use me_cleaner there, and more or less understand exactly what it does. Hopefully this document will clear some of that up.
