UsingSystemSetup:DellPrecision™WorkStation420SystemsUser'sGuide

Overview

Each time you turn on your computer system or press the reset button, the system scans the system configuration for changes. If the system

detects any changes, it generates messages that identify them. If required, the system then prompts you to enter System Setup to correct any

settings.

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.

After you set up your system, run System Setup to familiarize yourself with your system configuration information and optional settings. 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steps:

1. Press the power button to 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 to press <F2> and cannot enter System Setup, let the system complete the startup 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.
