Re: Add A second CPU,need i software configuration
The only thing you'll need to do (software wise) is to ensure you're running an SMP kernel.
This should be available via up2date (or if you're not doing updates, on the distribution CD's).

If you use up2date, just 'up2date -i kernel-smp'.

Re: Add A second CPU,need i software configuration
you have to install SMP kernel. if it is redhat then the package name would be kernel-smp-* install the package and reboot the system and on next reboot you should be able to see two entries in your boot loader.
First and default entry for SMP kernel and second for UP kernel. boot through SMP kernel and if it boots up fine and cat /proc/cpuinfo shows two processor then you are done. If it fails to boot through SMP kernel then try booting it through UP kernel and see whether that solves the problem.
no other packages need to be recompiled and you dont have to pay any extra license for adding one more CPU :)
