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.

http://www.livepublishing.co.uk/pcextreme/page_316.shtml

I havnt tried this personally.

But, other than that it is not supported.

Thanks

David Lodeiro
