System Settings
Each time you start your computer, it compares the installed hardware with the system configuration information stored in nonvolatile random-access memory
(NVRAM). If the system detects a discrepancy, it generates an error message for each incorrect configuration setting.
You can use system settings as follows:
l To set user-selectable options such as date and time or system password
l To set the current configuration information such as the amount of memory or type of hard drive installed
You can view the current settings at any time. Dell recommends that you record the information for future reference. If you have a line printer connected to the
parallel port on your computer, you can print the system setup screens by pressing <Print Screen>.
Before you use system setup, you need to know the kind of diskette drive(s) and hard drive(s) installed in your computer. If you are unsure of this information,
see the Manufacturing Test Report that came with your system and is located in the Dell Accessories folder.
Entering System Setup
1. Turn on your system.
2. If your system is already on, restart it.
3. When F2 = Setup appears in the upper-right corner of the screen, press <F2>.
If you wait too long and your operating system begins to load into memory, let the system complete the load operation; then restart the system and try again.
System Setup Screens
The system setup screens display the current configuration information for your computer. Information on the screen is organized into four areas:
l Title — the box at the top of all screens that lists the computer system name.
l Computer data — two boxes below the title box that display your system processor, level 2 (L2) cache, service tag, and the version number of the basic
input/output system (BIOS).
l Options — a scrollable box listing options that define the configuration of your computer, including installed hardware, power conservation, and security
features.
Fields to the right of the option titles contain settings or values. Those that you can change appear bright on the screen. Those that you cannot change
(because they are set by the computer) appear less bright. When <Enter> appears to the right of an option title, press <Enter> to access a pop-up
menu of additional options.
l Key functions — a line of boxes across the bottom of all screens that lists keys and their functions within system setup.
l Help — press <F1> for information in the currently highlighted option.
System Setup Navigation Keys
The following table lists the keys you use to view or change information in system setup and to exit setup.
