System Setup 19 System Setup This computer offers you the following options: • • Access System Setup by pressing Bring up a one-time boot menu by pressing Press to enter System Setup and make changes to the user-definable settings. If you have trouble entering System Setup using this key, press when the keyboard LEDs first flash.
When you enter the or keystroke correctly, the computer beeps. The key sequence invokes the Boot Device Menu. Since the one-time boot menu only affects the current boot, it has the added benefit of not requiring the technician to restore the customer's boot order after completing troubleshooting. Timing Key Sequences The keyboard is not the first device initialized by Setup. As a result, if you press a keystroke too early, you lock out the keyboard.
Beep Codes and Text Error Messages The OptiPlex BIOS is capable of displaying error messages in plain English, along with beep codes. If the BIOS determine the previous boot was unsuccessful, it displays an error message similar to the following: Previous attempts at booting the system have failed at checkpoint ______. For help resolving this problem, please note this checkpoint and contact Dell Technical Support. Navigation The computer setup can be navigated by either the keyboard or the mouse.
