It's much more than that: in the CPU and PCH chip you have 3 (THREE!) cpus
derived from vintage 486 plus a few modern opcodes (probably related to

related subsystems.

The whole harness is supposed to be disabled as described in the link to
the Positive Technologies team.

Yep, that's it! Three cores that run their own OS separated from the main
CPU. Scary!
