Piddling problem with Device Manager

[Gustavus]

I have three computers -- with more or less the same complement of devices. On two of them Device Manager does not show a category "Processors". On one of them it does, but mysteriously shows two processors. In other words if I expand Processors on that machine there are two identical lines each saying "Intel Pentium 4 CPU 2.4GHz". The machine in question is on an ABIT IS7-E2G motherboard (single Processor). Checking to show hidden devices on the two that do not have a category "Processors" does not cause Processors to be added.

As I said the problem is piddling, but I would like to know why one machine shows a category Processors and then why it shows two identical processors.

Thanks.

PS
I did the obvious of course and removed one of the processor entries, but on reboot they are both there again.

Note added:
Apparently I was focusing on the wrong "piddling problem". These are all multi threading Pentium 4 processors, so for Device Manager to show a category "Processors' with two entries the same is normal. The new piddling problem is why the other two do not. That is a less interesting problem, so I withdraw the question. The other two machines are both based on ABIT IC7-G motherboards so perhaps the difference in bahavior for Device Manager is motherboard related.

Your added note explains why that may be. I have three systems also - two are P4 "desktops" and the thrid is a much newer notebook w/Centrino P-Mobile. Desktop 1 shows one CPU. Desktop 2 shows one CPU. Laptop shows one CPU. All have multithreading capability. None are Abit mobos. So, that could be the difference.

Why not try removing BOTH processors and rebooting to see if it finds two new ones?
