CAUTION: To prevent possible damage to the original diagnostics dis-
kette, always use a backup copy of the diagnostics diskette when servicing a
user's system. If the user has not already made a backup copy of the diagnostics
diskette, do so before you run the diagnostics.
To start the diagnostics, turn off the computer, insert a diagnostics diskette into
the diskette drive, and then turn on 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 which memory address failed.
If no errors are found in main memory, the diagnostics loads and the Diagnos-
tics Menu appears. This menu lets you choose the following options or exit to
the MS-DOS prompt:
•
RUN QUICK TESTS
locate the failure or to indicate where further testing may be needed to iso-
late a failure
•
— Runs all tests for a thorough test of the computer
RUN ALL TESTS
•
RUN SPECIFIC TESTS
— Runs selected tests from all test groups to quickly
— Tests a particular area or subsystem
