Greg: As I understand it, the smp kernel is for multiprocessors and the non-smp is for a single processor. You will definitely want to use the smp kernel.

In the meantime I have installed Centos 4.4. Sorry for asking such a basic question but what is the difference between CentOS (2.6.9-42.0.8.ELsmp) and CentOS (2.6.9-42.0.8.EL) Both kernels have been installed, but I have not been able to find which one is best to use for what purposes.
