"Activating" Dual Core

Hi,

I have a notebook which has a Centrino Duo CPU but Windows is only
recognising one othe cores. I think this is down to the fact that the
machine was imaged from a Single CPU Machine. Is there a way, without a
total re-install of Windows, which will allow me to "activate" dual
core? (getting Windows to actually know the CPU is there!). This is
Windows XP Pro.

The BIOS is already set to Dual Core aware but Windows doesn't know jack
about it at present.

TIA

The wrong HAL is being loaded because of the image. The easiest way to fix
it is with a repair install.

Repair Installation *might* fix it up.
The problem is the HAL was not loaded for MultiProcessor systems.
