Using the System Setup Program
DellPrecision™MobileWorkstationM20User'sGuide
Overview
Viewing the System Setup Screens
System Setup Screen
Commonly Used Options
Overview
You can use system setup as follows:
l To set or change user-selectable features—for example, your computer password
l To verify information about the computer's current configuration, such as the amount of system memory
After you set up the computer, run system setup to familiarize yourself with your system configuration information and optional settings. You may want to
write down the information for future reference.
The system setup screens display the current setup information and settings for your computer, such as:
l System configuration
l Boot order
l Boot (start-up) configuration and docking-device configuration settings
l Basic device-configuration settings
l System security and hard-drive password settings
Viewing the System Setup Screens
1. Turn on (or restart) your computer.
2. WhentheDELL™logoappears,press<F2>immediately.IfyouwaittoolongandtheWindowslogoappears,continuetowaituntilyouseethe
Windows desktop. Then shut down your computer and try again.
System Setup Screen
The System Setup screen consists of three panes. The left pane contains a menu of control categories. To show or hide subcategories, select a category (such
as System, Onboard Devices, or Video) and press the <Enter> key. The right pane displays information about the category or subcategory.
The bottom pane describes how to control System Setup with key functions. Use the keys to select a category, modify settings, or exit System Setup.
Commonly Used Options
Certain options require that you reboot the computer for new settings to take effect.
Changing the Boot Sequence
The boot sequence, or boot order, tells the computer where to look to find the software needed to start the operating system. You can control the boot
sequence and enable/disable devices using the Boot Order page of system setup.
The Boot Order page displays a general list of the bootable devices that may be installed in your computer, including but not limited to the following:
NOTE: Your operating system may automatically configure most of the options available in system setup, thus overriding options that you set through
system setup. (An exception is the External Hot Key option, which you can disable or enable only through system setup.) For more information on
configuring features for your operating system, see your Windows Help (Microsoft®Windows®2000) or the Windows Help and Support Center
(Windows XP).
NOTICE: Unless you are an expert computer user or are directed to do so by Dell technical support, do not change the system setup settings. Certain
changes might make your computer work incorrectly.
NOTE: To change the boot sequence on a one-time-only basis, see "Performing a One-Time Boot."
l Diskette Drive
l Modular Bay HDD
l Internal HDD
l CD/DVD/CD-RW Drive
During the boot routine, the computer starts at the top of the list and scans each enabled device for the operating system start-up files. When the computer
finds the files, it stops searching and starts the operating system.
To control the boot devices, select (highlight) a device by pressing the down-arrow or up-arrow key, and then enable or disable the device or change its order
in the list.
l To enable or disable a device, highlight the item and press the space bar. Enabled items appear as white and display a small triangle to the left;
disabled items appear blue or dimmed without a triangle.
l To reorder a device in the list, highlight the device and then press <u> or <d> (not case-sensitive) to move the highlighted device up or down.
Boot sequence changes take effect as soon as you save the changes and exit system setup.
Performing a One-Time Boot
You can set a one-time-only boot sequence without entering system setup. (You can also use this procedure to boot the Dell Diagnostics on the diagnostics
utility partition on your hard drive.)
1. Shut down the computer through the Start menu.
2. If the computer is connected to a docking device (docked), undock it. See the documentation that came with your docking device for instructions.
3. Connect the computer to an electrical outlet.
4. Turn on the computer. When the DELL logo appears, press <F12> immediately. If you wait too long and the Windows logo appears, continue to wait
until you see the Windows desktop. Then shut down your computer and try again.
5. When the boot device list appears, highlight the device from which you want to boot and press <Enter>.
The computer boots to the selected device.
The next time you reboot the computer, the previous boot order is restored.
Changing Printer Modes
Set the Parallel Mode option according to the type of printer or device connected to the parallel connector. To determine the correct mode to use, see the
documentation that came with the device.
Setting Parallel Mode to Disabled disables the parallel port and the port's LPT address, which frees computer resources for another device to use.
Changing COM Ports
Serial Port allows you to map the serial port COM address or disable the serial port and its address, which frees computer resources for another device to
use.
Enabling the Infrared Sensor
1. Under Onboard Devices, select Fast IR.
2. Press <Enter> to select the Fast IR setting, and use the right-arrow or left-arrow keys to change the setting to a COM port.
3. Press <Enter> and then <Esc> to save the changes and exit the system setup program.
After you enable the infrared sensor, you can use it to establish a link to an infrared device. To set up and use an infrared device, see the infrared device
documentation and the Windows Help and Support Center (Help in Windows 2000).

Using Smart Cards
DellPrecision™MobileWorkstationM20User'sGuide
About Smart Cards
Installing a Smart Card
About Smart Cards
Smart cards are portable credit-card shaped devices with internal integrated circuits. The top surface of the smart card usually contains an embedded
processor located under the gold contact pad. The combination of the small size and integrated circuits make smart cards valuable tools for security, data
storage, and special programs. Using smart cards can improve system security by combining something a user has (the smart card) with something only the
user should know (a PIN) to provide more secure user-authentication than passwords alone.
Installing a Smart Card
You can install a smart card in the computer while the computer is running. The computer automatically detects the card.
To install a smart card:
1. Hold the card so that the gold contact pad is facing upward and pointing toward the smart card slot.
2. Slide the smart card into the smart card slot until the card is completely seated in its connector. The smart card will protrude approximately 1/2 inch from
the slot. The smart card slot is located below the PC Card slot.
If you encounter too much resistance, do not force the card. Check the card orientation and try again.

Ensuring Sufficient Power for Your Computer
Your computer is designed to use the 90-W AC adapter; for optimum system performance, you should always use this adapter.
The 65-WACadaptersusedinotherDell™portablecomputerscanbeusedwithyourcomputer,buttheywilldecreasesystemperformance.Usingless-
powerful AC adapters, including the 65-W AC adapter, will cause you to receive a WARNING message.
Docking Power Considerations
Due to the extra power consumption when a computer is docked to the Dell D/Dock, normal computer operation is not possible on battery power alone.
Ensure that the 90-W AC adapter is connected to your computer when the computer is docked to the Dell D/Dock.
Docking While the Computer Is Running
If a computer is connected to the Dell D/Dock or Dell D/Port while the computer is running, presence of the docking device is ignored until the AC adapter is
connected to the computer.
AC Power Loss While the Computer Is Docked
If a computer loses AC power while docked to the Dell D/Dock or Dell D/Port, the computer immediately goes into low-performance mode.
