Vista (64bit Ultimate) reports only 1 Core on new AMD X2 CPU

Can anyone confirm this?

Running Vista 64bit Ulitmate and upgraded my Single Core AMD to an X2.
I was expecting Device Manager and Task Manager to show 2 cores but instead
only shows one.

Does Vista show Dual Core CPU's as a single device by design or is there
something wrong here and if so....anyone know how to resolve this?

Thanks in advance

I see two cores in Vista Ultimate x64..

Ok...done some research and it appears that the HAL needed to be replaced.
This sorted it.

How did you do that?
My 64 bit Ultimate Vista lists two cpus in Device manager but not in
performance manager or even when I run Intels ID program.
Yet bios is up to date and if I boot to Xp on other drive, both cores
are being used.

Thanks in dvance
