I know all that. That's not what I asked. The help on menuconfig for this option specifically said it's for Pentium 4's with hyperthreading. It doesn't mention Pentium IIs for instance (I also have a twin Penitum II system), and it doesn't mention Xeons (my main system has two Xeon procesors). So I repeat the question.
Can't you read? Pedro answered your question with his first word. YES.
