I know one way to check CPU info:
first type cd /proc, this would get you to the proc dir. Then type
cat cpuinfo (i think this is the way to do it), this would give you information on your cpu.
Although I have Redhat 7.1, but I think it works on 6.2 as well.
Hope it helps
ps. I'm not at home how, so I can't check if it works. I'll check it as soon as I get home.
