Problem with Dell

Hi:

A friend gave me an old Dell Dimension X P S T500 computer.

I have tried the F1, F2, F3, F8, F10, F11, F12 and Delete Keys but cannot get into the setup utilities. If anyone knows how to get into the setup utilities on that computer, I would greatly appreciate your sharing that information with me.

Thanks for your assistance with this problem and I look forward to your quick response.

Regards.
