Did you try another keyboard? –  Moab Nov 14 '11 at 3:02

Go to the Dell support website, go to Drivers and Downloads, enter the service tag of your system (should be 7 alphanumeric characters on a small sticker on the back or top of your system), and you'll be presented with a list of drivers and BIOS updates for your system.

The BIOS updater runs from Windows. You can run it from a WinPE boot CD/USB drive or possibly a BartPE boot CD/USB drive, which you will have to either make on another working computer, or obtain from someone else.
