Overview

Each time you turn on your computer system or press the reset button, the system compares the hardware installed in the system to the hardware

listed in the system configuration information stored in nonvolatile random-access memory (NVRAM) on the system board. If the system detects a

discrepancy, it generates error messages that identify the incorrect configuration settings. The system then prompts you to enter System Setup to

correct the setting.

You can use System Setup as follows:

l To change the system configuration information after you add, change, or remove any hardware in your system

l To set or change user-selectable options—for example, the time or date on your system

You can view the current settings at any time. When you change a setting, in many cases you must reboot the system before the change takes

effect.

Dell has set up your system for optimal operation, and under most circumstances you should not have to change any of the settings. After you set

up your system, run System Setup to familiarize yourself with your system configuration information and optional settings in case you need to

change them. Dell recommends that you print the System Setup screens (by pressing <Print Screen>) or record the information for future

reference.

Before you use System Setup, you need to know the kind of diskette drive(s) and hard-disk drive(s) installed in your computer. If you are unsure of

this information, see the Manufacturing Test Report that was shipped with your system and is located in the Dell Accessories folder.

Entering System Setup

ToenterSystemSetup,performthefollowingstep

1. Turn on your system.

If your system is already on, shut it down, and then turn it on again.

2. When the Press <F2> to Enter Setup window 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 shut down the system

and try again.

System Setup Screen

The System Setup screen displays the current setup and configuration information and optional settings for your system. Information on the

System Setup screen is organized in four areas:

l Title — The box at the top of all screens lists the system name.

l System data — The two boxes below the title box display your system processor, level 2 (L2) cache, service tag, and the version number of

the basic input/output system (BIOS).

l Options — The main area of the screen is a scrollable window containing options that define the installed hardware in your computer and the

power conservation and security features for your computer.

Fields next to the options contain settings or values. You can change those values that appear bright on the screen. Options or values that

you cannot change (because they are determined or calculated by the computer) appear less bright.

l Key functions — The line of boxes across the bottom of all screens lists keys and their functions within System Setup.
