You don't need to know the correct settings. The settings are correct by default. If you messed with them and need to reset them to default, there should be an option to restore defaults in the bios. If you can't find it, turn of the computer, unplug it, open it and find a "watch battery" on the motherboard. Remove it. Wait a couple seconds then put it back. You just deleted all the changes made to the bios and everything will be back to defaults when you boot up again.
