Insert a copy of theDell Diagnostics Diskette into the diskette drive. Turnon all peripherals and the computer.2. For OptiPlex NX1 systems, enter the System Setup program, set DisketteDrive A to 3.5 Inch, 1.44 MB, and set Primary: under Drives: to Auto (seeFigure A-1). Then press to reboot the system.Starting the diagnostics causes the Dell logo to appear on the monitorscreen, 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 isdetected, a message indicates which DIMM has failed. If no errors arefound in main memory, the diagnostics loads and the Diagnostics Menuappears.3. Observe the monitor screen for the Diagnostics Menu.This menu lets you choose the following options or exit to the MS-DOSprompt:á Run Quick Tests — Runs selected tests from all test groups to quicklylocate a failure or to indicate where further testing is needed to isolatea failureá Run All Tests — Runs all tests for a thorough test of the systemá Run Specific Tests — Tests a particular area or subsystemIf the Diagnostics Menu does not appear, check the diskette drive connec-tions, insert a copy of the diagnostics diskette into the diskette drive, andreboot the system. If the Diagnostics Menu still does not appear, proceedto the next section, “Getting Help.”The diskette-based diagnostics consists of the same test groups described in“Hard-Disk–Based Diagnostics (OptiPlex NX1 Systems Only)” found earlier inthis chapter. For a complete description of the diskette-based diagnostics, see“Diskette-Based Diagnostics” in the onlineNetwork Administrator’s Guide oronlineSystem User’s Guide.*HWWLQJ+HOSIf none of the troubleshooting procedures in this chapter or the tests in theserver-based, hard-disk–based, or diskette-based diagnostics reveals thesource of the problem or leads to the proper troubleshooting steps for deter-mining the source of the problem, call Dell for technical assistance.
