    On laptops, it's frequently the case that c000:0003 will jump to a
    section of code that is no longer mapped into the address space.
    Instead, it's entirely possible that some other section of BIOS will be
    mapped there. The resulting behaviour is undefined, and can cause the
    hardware to hang.
