XP sp2. Task Manager graph only showing 1 CPU

Hello,

I have a Dell Precision Workstation with Windows XP SP2 and 2 Xeon CPU's and am only seeing 1 processor in the task manager graph.
So far I have checked the following:

Bios sees 2 processors (0 and 1)
Hyperthreading is turned OFF in the bios. (recommended by the manufacturer of a software package we use)
Device manager under Computer shows ACPI Multiprocessor PC
Device manager under Processors shows 2 processors
Task Manager/Performance/View/CPU History/One Graph All CPU's shows 1 graph
Task Manager/Performance/View/CPU History/One Graph Per CPU shows 1 graph

Am I missing something? Thanks.

The processor performance section in task manager is "expressed as a percentage of total capacity" according to my windows book so i'm guessing that it works out the total from both your processors and then displays how much is being used!

James,

Thanks for the response.

I would agree with your statement if looking at "One Graph All CPU's".

Funny thing is "One Graph Per CPU" is showing both CPU's today. Two graphs. Not sure why it has changed from what I was seeing the other day.
