PAE means physical address extension and allows 32bit cpus to make use of
memory beyond the 4gb limit addressable with 32bit.
Centos/RHEL 6 doesn't support cpus without this as it's hard to come by a
machine these days that doesn't have this extension.
So basically your hardware is too old to run Centos 6.
