I've seen many BIOS that allow you to do that

  I've never seen a BIOS not allow that. Often called "multi-processing" or something similar in BIOS.

    I've haven't seen a bios that would allow disabling all cores except for one since at least intel 2xxx series - there is almost always a switch to disable hyperthreading, but a switch to disable all cores bar one?
