Before starting the Dell Diagnostics, you must configure the computer cor-
rectly. For more information, see “Before You Start Testing” in Chapter 4,
“Running the Dell Diagnostics,” of the
Reference and Troubleshooting Guide
.
Follow these steps to start the diagnostics:
1. Install a CD-ROM drive in the options bay.
2. Turn off the computer.
3. Place a copy of the
Dell Diagnostics Diskette
in the diskette
drive, and boot
the computer.
Starting the diagnostics causes the Dell logo screen to appear, followed by a
message indicating that the diagnostics is loading. Before the diagnostics
loads, a program tests the portion of main memory (RAM) required for loading
the diagnostics. If a main memory error is detected, a message appears on the
screen telling you a memory module has failed.
If no errors are found in main memory, the diagnostics loads, and the Diag-
nostics Menu appears. This menu lets you choose the following options or
exit to the MS-DOS
®
prompt:
Run All Tests — Runs all tests for a thorough test of the computer
Run Quick Tests — Runs preselected tests to quickly locate a computer
failure or to indicate where further testing is needed to isolate a failure
Run Specific Tests
— Tests a particular area or subsystem of the
computer
