Dell Latitude X300 - Manual (Page 103)

Certain options require that you reboot the computer for new settings to take effect.
Changing the Boot Sequence
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:
l Removable Devices
l Hard Drive
l CD-ROM Drive
l Onboard NIC
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.)
1. Turn off the computer.
2. 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.
3. 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
If your computer is connected to the media base (docked), 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, freeing 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, freeing computer resources for another device to use.
Enabling the Infrared Sensor
1. Enter the system setup program:
a. Turn on your computer.
b. Press <F2> when the Dell™ logo appears.
2. Press <Alt><P> until you locate Infrared Data Port under Basic Device Configuration.
3. Press the down-arrow key to select the Infrared Data Port setting, and press the right-arrow key to change the setting to a COM port.
4. Press the down-arrow key to select the Infrared Mode setting, and press the right-arrow key to change the setting to Fast IR or Slow IR.
It is recommended that you use Fast IR. If the infrared device cannot communicate with your computer, shut down the computer and repeat steps 1
through 5 to change the setting to Slow IR.
5. Press <Esc><Enter> and Yes to save the changes and exit the system setup program. If you are prompted to restart your computer, press Enter.
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
Help and Support Center (Help in Windows 2000).
NOTE: To change the boot sequence on a one-time-only basis, see " Performing a One-Time Boot ."
NOTE: Ensure that the COM port that you select is different from the COM port assigned to the serial connector.
