The Dell Diagnostics contains tests that aid in troubleshooting all major com-
ponents of the computer system. To run the tests, you must first create a
diagnostics diskette using the
Dell Server Assistant CD as described in “Creat-
ing Diskettes” in Chapter 2 of the
User’s Guide.
To start the Dell Diagnostics, turn off the system, insert a diagnostics diskette
into drive A, and then turn on the system.
Starting the diagnostics causes the Dell logo screen to appear on the monitor
screen, 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 RAM error is detected, a mes-
sage appears on the screen telling you which DIMM has failed.
If no errors are found in RAM, the diagnostics loads and the Diagnostics Menu
appears. This menu lets you choose the following options or exit the Dell
Diagnostics:
‡
Run All Tests — Runs all tests for a thorough check of the system
‡
Run Quick Tests — Runs selected tests from all test groups to quickly
locate a failure or to indicate where further testing is needed to isolate a
failure
‡
Run Specific Tests — Tests a particular area or subsystem

Dell Diagnostics reveals the source of the problem or leads to the proper trou-
bleshooting steps for determining the source of the problem, call Dell for
technical assistance. For instructions, see the chapter titled, “Getting Help,” in
the
Installation and Troubleshooting Guide.
