Keith, I don't see that you identify what sort of old machine you're
trying to use.
You should be aware that current versions of Centos/RHEL REQUIRE some
flavor of i686-class processor at minimum. that means Pentium Pro/Pentium II
or later.
Of course, you may also be hitting some situation where there's some really
obsolete hardware in the machine for which newer systems don't have the
driver built in.
or a bad image burn, too, since you say you haven't yet tested it.
Good luck!
