Enabling my second CPU

Hi,
I have this same motherboard, and it doesnt actually support anything but
dual MP processors. There is a mod that you can do to a XP processor that
will make the motherboad believe that it is a MP processor and enable you to
use it, but this would void any warranty.

I havnt tried this personally.
But, other than that it is not supported.
Thanks
David Lodeiro
