Does your task manager and/or device manager show two processors?

I hadn't thought to check those items.
Device manager shows 2 instances of the processor.
Task manager / performance tab shows only 1 instance.
Now I am really confused.

did you install xp with ht enabled? or only with 1 cpu?

Thanks Alonzo,

is there such an option in xp installation?
I have not seen such a thing, but I am quite inexperienced.
Nick.
