Overview

Use system setup as follows:

Before you use system setup, it is recommended that you write down the system setup screen information for future reference.

NOTICE: Unless you are an expert computer user, do not change the settings for this program. Certain changes can make your computer work incorrectly.

Entering System Setup

  1. Turn on (or restart) your computer.

  2. When the blue DELL™ logo is displayed, you must watch for the F2 prompt to appear.

  3. Once this F2 prompt appears, press <F2> immediately.

NOTE: The F2 prompt indicates that the keyboard has initialized. This prompt can appear very quickly, so you must watch for it to display, and then press <F2>. If you press <F2> before you are prompted, this keystroke will be lost.
  1. If you wait too long and the operating system logo appears, continue to wait until you see the Microsoft® Windows® desktop. Then, shut down your computer and try again.

System Setup Screens

The system setup screen displays current or changeable configuration information for your computer. Information on the screen is divided into three areas: the options list, active options field, and key functions.

Options List — This field appears on the left side of the system setup window. The field is a scrollable list containing features that define the configuration of your computer, including installed hardware, power conservation, and security features.

Scroll up and down the list with the up- and down-arrow keys. As an option is highlighted, the Option Field displays more information about that option and the option's current and available settings. By pressing <Enter> or the left and right arrow keys, you can toggle between a primary topic (collapsed) and subtopics (expanded).

Option Field — This field contains information about each option. In this field you can view your current settings and make changes to your settings.

Use the right and left arrow keys to highlight an option. Press <Enter> to make that selection active.

 

 

 

 

 

 

 

 

 

Key Functions — This field appears below the Option Field and lists keys and their functions within the active system setup field.

System Setup Options

NOTE: Depending on your computer and installed devices, the items listed in this section may not appear, or may not appear exactly as listed.

System

System Info

Lists system information such as the computer name, the BIOS version number and date, system tags, and other system-specific information.

NOTE: The system name listed in the BIOS may not appear exactly as the name that appears on the computer or in the computer's documentation.

Processor Info

Identifies whether the computer's processor supports Hyper-Threading and lists the processor bus speed, processor ID, clock speed, and L2 cache.

Memory Info

Indicates amount of installed memory, memory speed, channel mode (dual or single), and type of memory installed.

Date/Time

Displays current date and time settings.

Boot Sequence

The computer attempts to boot from the sequence of devices specified in this list.

NOTE: If you insert a boot device and restart the computer, this option appears in the system setup menu. To boot from a USB memory device, select the USB device and move it so it becomes the first device in the list.

Drives

Diskette Drive

Identifies and defines the floppy drive attached to the FLOPPY connector on the system board as Off, USB, Internal, or Read Only.

Drives 0 through 1

Identifies the drives attached to the SATA connectors on the system board, and lists the capacity for hard drives.

Drives 2 through 3

Enables or disables an ATA device (such as a CD or DVD drive).

SATA Operation

Identifies and defines the SATA controller settings for RAID. You can set the SATA controller to RAID Autodetect/AHCI, RAID Autodetect/ATA, or RAID On.

Onboard Devices

Integrated NIC Controller

You can set the NIC to On (default), Off, or On w/ PXE. When the On w/ PXE setting is active (available only for the future boot process), the computer prompts you to press <Ctrl><Alt><b>. Pressing this key combination causes a menu to display that allows you to select a method for booting from a network server. If a boot routine is not available from the network server, the computer attempts to boot from the next device in the boot sequence list.

Integrated Audio Controller

Enables or disables the onboard audio controller.

USB Controller

Set to On (default) so that USB devices will be detected and supported in the operating system.

Card Reader

This field enables and disables the Media Card Reader.
Off = Media Card Reader is disabled.
On = Media Card Reader is enabled.
The factory default setting is On.

This option appears only if a Media Card Reader is installed.

Video

Primary Video

This setting specifies which video controller is primary when two video controllers are present on the computer.

Video Memory Size

Offering selectable options of 1MB and 8MB, this field configures the system memory allocation reserved for the integrated video controller.

Performance

HyperThreading

If your computer's processor supports Hyper-Threading, this option appears in the Options List.

HDD Acoustic Mode

  • Bypass (default) — Your computer does not test or change the current acoustics mode setting.
  • Quiet — The hard drive operates at its most quiet setting.
  • Suggested — The hard drive operates at the level suggested by the drive manufacturer.
  • Performance The hard drive operates at its maximum speed.

NOTE: Switching to performance mode will cause the drive heads to move faster, causing the hard drive to be noisier. However, some drives may not see an increase in data transfer rates.

NOTE: Changing the acoustics setting does not alter your hard drive image.

This section displays available system security options.

Admin Password

This option provides restricted access to the computer's system setup program in the same way that access to the system can be restricted with the System Password option.
