IIRC, in Intel's case, the chipset has the vendor keys burned into it. This is not an issue, as the chipset is not a part you would remove from the board and use elsewhere.
- my123 5y agoIn Intel’s case the ME as a whole is on the PCH.
- amluto 5y agoIntel’s or AMD’s assistance is not needed at all. There is a rather boring flash chip connected by SPI to the CPU and/or PCH. One could interpose a microcontroller that verifies whatever it pleases on that SPI link.
- my123 5y agoThat’s the approach used by the Apple T2. On the Intel side, it’s the chipset soldered on the motherboard which does that verification, so CPU swapping isn’t affected.
