To return to the boot sequence you use for normal operation, repeat steps 1 through 5, customizing the boot sequence to fit your

When you start the diagnostics, the Dell logo screen appears, followed by a message telling you that the diagnostics is loading.
After the diagnostics loads, the Diagnostics Menu appears (see Figure 1). The menu allows you to run all or specific diagnostic tests
or to exit to the MS-DOS® prompt.
For a quick check of your computer, select Quickly Test All Devices. This option runs only the subtests 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 odds of tracing the
source of the problem quickly. For a thorough check of your computer, select Fully Test All Devices. To check a particular area of your
computer, select Select Devices to Test.
To select an option from this menu, highlight the option and press <Enter>, or press the key that corresponds to the highlighted letter in
the option you choose.
