Adding a second CPU

[Langdon Stevenson]

I have just switched my server from one 450 Mhz CPU to a pair of 500 Mhz 
CPUs.  No problems so far.

Machine started and detected both CPUs. Fedora 7 booted and

   cat /proc/cpuinfo

returns all the correct information.  Bot CPUs show up as expected.

My question: do I need to do anything else to Fedora to make it use both 
CPUs?  Like install a different kernel?  Or will it just use the second CPU?

Thanks for any feedback.

Regards,
Langdon
