Clearly states:
This vulnerability does not exist on Intel-based consumer PCs.
Now while I agree, effort should be made to triple-check that is the case, by following these detection methods.
We should make note that it primarily affects Intel-based PC/Laptops that advertise vPro technology (look at the above link I posted for sample images) and even then, vPro must be enabled in the BIOS.
Typically you'd find this in "enterprise" quality PC's... for instance those that are issued by Banks, Insurance Companies, and other Large Corporations to their employees.
Consumer-grade Intel computers (the cheap ones you buy at Walmart and Best Buy) typically don't have this vPro BIOS setting, but I recommend you check your system anyway.
