...delete found my answer
when you first turn on the computer, when the dell logo comes up push F2, that will put you into the bios setup. the first screen you see will show you your model number, bios version, service tag number. you can see your processor information, it tells you what your system is. you have to be quick to push f2, coz that screen is only up for about a 1/4 of a second. when you are done, at the bottom of the screen it will tell you what button to push to get out. i think it's escape. then the next page at the topright is the choices to get out of the bios. good luck.
