NOTE: Keyboard failure may result when a key is held down for extended periods of time. To avoid possible keyboard failure, press and release <F12> in even intervals to open the Boot Device Menu.

NOTE: If at any time a message appears stating that no diagnostics utility partition has been found, run the Dell Diagnostics from your Drivers and Utilities disc (see "Starting the Dell Diagnostics From the Drivers and Utilities Disc" on page 34).
