(aka) Is it possible to hack CPUID instruction or BIOS to make it show wrong CPU information?
Yesterday, I was having a chat with computer sales guy. He is little close to me. During the conversation he said that,
A processor is not what it shows in bios. On inquiring further he said that they know a guy who can make a processor look like another. I didn't believe him. Then he said that for past few months they've been selling computers with Celeron processors by posing them as duo core. I was shocked! I started arguing with him about how its not possible. He simply gave a smile.
I've been racking my brain since then on how on the earth is it possible:
- He might be lying to me, I mean what ever he said is a lie. But I don't see any point on why he would do that.
- They are actually hacking the bios to show wrong information?
- They are hacking
CPUIDprocessor instruction to make it return wrong values. I think its impossible.
