Thanks for the suggestion, but I can not find anything in this BIOS that 
allows me to make any useful changes involving the hard drive or it's 
controller.    I am just using F2 when system boots which seems pretty 
standard with Dell, and I get into the setup, but it seems like they give 
pretty limited options with this machine.

Thanks, Mike
