Also review the documentation provided with any installed expansion cards and other devices for additional interrupt information for the specific devices.

Running the Diagnostics

The diskette-based diagnostics (included with the system) contains tests that aid in troubleshooting all major components of the computer system.

CAUTION: To prevent damage to the original Dell Diagnostics Diskette, always use a backup copy of the diagnostics diskette when servicing a user’s system. Dell recommends that users make several copies of this diskette to ensure that one is always available.

To start the diagnostics, turn off the computer, insert a copy of the Dell Diagnos- tics Diskette into drive A, and then turn on the computer.

Starting the diagnostics causes the Dell logo screen to display, 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 SIMM has failed.

If no errors are found in main memory, the diagnostics loads and the Diagnos- tics Menu displays. This menu lets you choose the following options or exit to the MS-DOS®prompt:

•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 All Tests — Runs all tests for a thorough check of the system

•Run Specific Tests — Tests a particular area or subsystem

See the chapter titled “Running the Diskette-Based Diagnostics” in the Diagnos- tics and Troubleshooting Guide for more information.
