Multiprocessor - simple question

I have a server running Windows Server 2003 Enterprise Edition.
I have added an additonal processor to this server.
How can I tell if Windows 2003 is actually using this new extra processor ?
Do I need to reinstall or is there a trick ?
Are there still two different HALs for single and multiprocessor ?

Go to Device Manager, Select the Computer section and read what it says.  If it says Uniprocessor, then it's only seeing one CPU.  If that's the case, you need to update the driver for the system to read it as multiprocessor.

Look in Taskmanager under "Performance.
How many cpu history windows do u see?
(for each Hyperthreating CPU there should  be 2 windows.)

OK. I have looked at these articels and I have gone into device manager and expanded Computer.
There is on sib-node called : Advanced Configuration and Power Interface (ACPI) PC
When I try to update the driver on this (i.e. to change the HAL to MPS) it doesn't work.
It doesn't offer any alternative.

And if NO other drivers are listed in step 7, then it might be that the system doesn't support multiple CPUs with 2003 - this is why it's important to post details on your system.  There may be a reason for this that I (and possibly others here) aren't yet aware of.
This is a Dell GX300 workstation wil two Pentium III 650 Mz processors.
Only offers me Standard PC and ACPI as alternatives.

What can I do ?
