Confirming the System Configuration Information
When you boot your computer from the Dell Latitude L400 ResourceCD, the diagnostics checks your system configuration information and
displays it in the Device Groups area on the main screen.
The following sources supply this configuration information for the diagnostics:
l The system configuration information settings (stored in nonvolatile random-access memory [NVRAM]) that you selected while using the
system setup program
l Identification tests of the microprocessor, the video controller, the keyboard controller, and other key components
l Basic input/output system (BIOS) configuration information temporarily saved in RAM
Do not be concerned if the Device Groups area does not list the names of all the components or devices you know are part of your computer. For
example, you may not see a printer listed, although you know one is attached to your computer. Because your printer is a parallel communications
device, the computer recognizes the printer by its LPT1 address and identifies it as a parallel port. You can test your printer connection in the
Parallel Portstests.
