Windows XP Pro is licencenced for not more than two Processors in a single computer and thus recognises your dual CPU configuration. Windows Home does not. Make sure you have Pro and not Home.

You may need to refer to your user guide in order to have BIOS recognise the second CPU, but I don't think it is necessary.

In XP Pro, go to Device Manager, double click on Computer, double click on ACPI Uniprocessor PC
In the Properties tab click on Driver tab and click on Update Driver
Click on Next to begin the Update Device Driver Wizard. In the next windowselect Display a list of known drivers then click on Next to continue.
Select Show all hardware of this device class and in the Manufacturers section, select [Standard Computers] and in the Models section, select ACPI Multiprocessor PC and then click on the Next buttton.
Click on Next to install the driver and when this is complete, click on Finish.
Close all windows and restart your PC when prompted.

It should reboot and be able to use both CPUs.

Good luck.
