Thanks Jaguarskx, I should have been more clear. I have no HD or OS installed. I have it posted here:

In your situation the only thing I can think of is the BIOS is corrupted. You can try to remove the CMOS battery to clear the BIOS settings. It probably will not work, but worth a try. Otherwise the BIOS chip itself needs to be replaced and you would need to go through Dell to do that assuming they have it stock for such an old laptop.
