System Setup Program: Dell Dimension Lxxxc Systems Reference
System Setup Program: Dell Dimension Lxxxc Systems Reference
Each time you turn on or restart your computer system, the system compares the hardware
installed in the system to the hardware listed in the configuration information stored in
nonvolatile random-access memory (NVRAM) on the system board. If the system detects a
discrepancy between the two, it generates error messages that identify the incorrect
configuration settings. The system then prompts you to enter the system setup program to
correct the setting.
You can use the system setup program as follows:
- To change the system configuration information after you add, change, or remove any
hardware in your system
- To set or change user-selectable options for example, the user password
Dell recommends that you print the system setup program screens (by pressing <Print
Screen>) or write down the information for future reference.
The system setup screens are organized as follows:
- At the top is a menu bar for accessing the main program screens.
- The box on the left side of each screen lists options that define the
installed hardware in the system. Fields beside
the options contain settings or values. You can change those that are enclosed in
brackets. Values that are grayed out contain status information reported by the system.
- The box on the right side of each screen displays help information
for the option with a currently highlighted field.
- The bottom right area lists keys and their functions for the
currently displayed screen.
The menu bar provides access to the following screens:
- Main screen Provides settings for the basic system configuration
- Advanced screen Provides detailed settings for some system features
- Security screen Provides indications and settings for system password and setup
password
- Boot screen Provides information about which device boots the system
- Exit screen Provides selections for saving and loading the configurations and
options
In addition to these screens, options identified by a right arrow
provide access to submenus.
Enter the system setup program as follows:
- Turn on (or restart) your system.
- When the blue Dell logo appears, press <Del>.
If you wait too long and the operating system begins to load into memory, let the
system complete the load operation. Then shut down the system and try again.
