NOTE: Your operating system may automatically configure most of the options available in the system setup program, thus overriding options that you set through the system setup program. (An exception is the External Hot Key option, which you can disable or enable only through the system setup program.) For more information on configuring features for your operating system, click Start
(or Start in Windows® XP) ®Help and Support.
You can use the system setup program as follows:
To set or change user-selectable features—for example, your Tablet-PC password
To verify information about the Tablet-PC's current configuration, for example, the amount of system memory
After you set up the Tablet-PC, run the system setup program 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 Tablet-PC, such as:
System configuration
Boot order
Boot (start-up) configuration and docking-device configuration settings
Basic device-configuration settings
System security and hard-drive password settings
NOTE: 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 Tablet-PC work incorrectly.
System Setup Screens
Viewing the System Setup Screens
Turn on (or restart) your Tablet-PC.
When the DELL™ logo appears, press <F2> immediately. If you wait too
long and the Microsoft® Windows® logo appears, continue to wait until
you see the Windows desktop. Then shut down your Tablet-PC and try
again.
NOTE: For information about a specific item on a system setup screen, highlight the item and see the Help area on the screen.
On each screen, the system setup options are listed at the left. To the right of each option is the setting or value for that option. You can change settings that appear as white type on the screen. Options or values that you cannot change (because they are determined by the Tablet-PC) appear less bright.
The upper-right corner of the screen displays help information for the currently highlighted option; the lower-right corner displays information about the Tablet-PC. System-setup key functions are listed across the bottom of the screen.
Commonly Used Options
Certain options require that you reboot the Tablet-PC for new settings to take effect.
NOTE: The information in this document may vary from the selections displayed on the system setup screens. Review the selections and instructions provided on the system setup screens for specific directions.
Changing the Boot Sequence
The boot sequence, or boot order, tells the Tablet-PC where to look to find the software needed to start the operating system. You can control the boot sequence and enable or disable devices using the Boot Order page of the system setup program.
The Boot Order page displays a general list of the bootable devices that may be installed in your Tablet-PC, including but not limited to the following:
Modular Bay HDD
Internal HDD
Optical Drive
During the boot routine, the Tablet-PC starts at the top of the list and scans each enabled device for the operating system start-up files. When the Tablet-PC 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.
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.
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 the system setup program.
Performing a One-Time Boot
You can set a one-time-only boot sequence without entering the system setup program. (You can also use this procedure to boot the Dell Diagnostics on the diagnostics utility partition on your hard drive.)
Shut down the Tablet-PC through the Start (
in Windows Vista®)
menu.
If the Tablet-PC is connected to a docking device (docked), undock it. See
the documentation that came with your docking device for instructions.
Connect the Tablet-PC to an electrical outlet.
Turn on the Tablet-PC. 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 Tablet-PC and try again.
When the boot device list appears, highlight the device from which you
want to boot and press <Enter>.
The Tablet-PC boots to the selected device.
The next time you reboot the Tablet-PC, the previous boot order is restored.
