List, I am experimenting with a Dual processor Supermicro and plan to use CentOS 5 when it is released. 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. Thanks, Greg Ennis
