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
l
System Setup program
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
l
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.
