I have not touched my Centos systems for over a year; it is time to get current to do some new, interesting things. So of course, 6.3, but which install? I run a local repo that I rsync from a mirror near me. So I believe I can use the Netinstall iso, but which one? How do I determine if I have a i386 or x86_64 processor? If x86_64 how do I determine if I use EFI or not?
