Running the System Diagnostics
You can run system diagnostics from either the utility partition on your hard drive or from a set of diskettes that you create from the Dell OpenManage Server
AssistantCD.
To run the diagnostics from the utility partition, perform the following steps:
1. Start the utility partition by pressing <F10> during POST.
2. From the utility partition's main menu, select the Run System Diagnostics option from Run System Utilities.
See "Using the Dell OpenManage Server Assistant CD" in the User's Guide for additional information about the utility partition.
To run the system diagnostics from the diskettes, perform the following steps:
1. Create a set of diagnostics diskettes using the Dell OpenManage Server Assistant CD.
See "Using the Dell OpenManage Server Assistant CD" in the User's Guide for information on creating diskettes.
2. Boot the system from the first diagnostics diskette.
If the system fails to boot, see "Obtaining Technical Assistance."
When you start the diagnostics, a message is displayed telling you that the diagnostics is loading. The Diagnostics menu appears. The menu allows you to
run all or specific diagnostic tests or to exit system diagnostics.
For a quick check of the system, select Test All Devices and then select Quick Tests. This option runs only the device tests that do not require user
interaction and that do not take a long time to run. Dell recommends that you choose this option first to increase the chance of tracing the source of the
problem quickly. To test a particular device, select Test One Device. For a complete check of the system, select Test All Devices and then select Extended
Tests.
To check a particular area of the system, choose Advanced Testing. When you select Advanced Testing, the main screen of the diagnostics appears. This
screen includes a listing of the various device groups in the system and the system's service tag.
To view data on test results, select Information and Results. Select Program Options to view the program options screen, which lets you set various test
parameters.
By selecting the Device Configuration option, you can see an overview of the devices in the system.
Selecting Exit to MS-DOS exits the diagnostics and returns you to the MS-DOS®operating system environment.
To select an option from the Diagnostics menu, highlight the option and press <Enter>, or press the key that corresponds to the highlighted letter in the
option you choose.
