I would guess you have to re-compile the kernel for SMP support... I don't know much about that -- I just use Mandrake 9.1 for my machines. Single or multi processor configurations get configured properly with the Mandrake install. They have an SMP kernel and an Enterprise kernel that both show up on the menu after installation. I guess the enterprise one is for systems with large memory. I use that one and specify 'mem=2048M' in my Lilo configuration.

Your Kernel SAYS its an SMP kernel.

What does <b>uname -a</b> return?

And the vodoo solution... does it still do it after you reboot?

it worked finally

Well, guess what, the BIOS settings had hyperthreading off. Once I turned it ON both processors were seen.
