Is there a reason why you're not installing Oracle Linux 6? 4.5 is over a decade old now and will almost certainly run badly on a laptop. If you have to run 4.5, you should possibly run it as a VirtualBox guest on another operating system.
When installing Oracle Linux 4.5 it skips the network installation step. I do not get a chance to configure a card, set up addresses, what have you.
