Confirming the System Configuration Information
When you boot your computer from your diagnostics diskette, 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:
The system configuration information settings (stored in nonvolatile random-access memory [NVRAM]) that you
selected while using the System Setup program
Identification tests of the microprocessor, the video controller, the keyboard controller, and other key
components
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. Instead, the printer is listed as a parallel port. The computer recognizes the parallel port as LPT1, which is
an address that tells the computer where to send outgoing information and where to look for incoming information.
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 Ports tests.
