Yes I was hving a simmilar problem so I did a Bing search. there was someone saying that the OS software didn't have a "BIOS" but something that he said was "better" which I forget the name of at the moment. Anyways you access this by pressing Control-Option-O-F at the same time. Sort of like the Control-Alt-Delete when your in windows but at the start up. He also said somehing about adds which I think would just get in your way. Anyways have fun testing this information.
