The OptiPlex G1 systems use diskette-based diagnostics, which contain tests
to aid in troubleshooting all major components of the system.

Starting the diagnostics causes the Dell logo 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 main memory error is
detected, a message indicates which DIMM has failed. If no errors are
found in main memory, the diagnostics loads and the Diagnostics Menu
appears.

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 test of the system
‡ Run Specific Tests — Tests a particular area or subsystem
If the Diagnostics Menu does not appear, check the diskette drive connections, insert a copy of the diagnostics diskette into the diskette drive, and
reboot the system. If the Diagnostics Menu still does not appear, proceed
to the next section, “Getting Help.”
For a complete description of the diskette-based diagnostics, see “DisketteBased Diagnostics” in the online Network Administrator’s Guide.

If none of the troubleshooting procedures in this chapter or the tests in the
server-based, hard-disk–based, or diskette-based diagnostics reveals the
source of the problem or leads to the proper troubleshooting steps for determining the source of the problem, call Dell for technical assistance. For
instructions, see “Contacting Dell” in the online System User’s Guide.
