Hi all,
I've installed the SLC4 64bit from the standard menu installation using 
the network at CERN.
I have a standard cern desktop HP dc-5850 with a AMD Phenom X4.

I discovered that the installed kernel does not support multicore;
this is what I see from /proc/cpuinfo

This is the kernel installed on my machine:

What I should do to install the 64bit multicore kernel and then modify 
the boot kernel?

thanks,
Daniele
