Software Diagnostic Packages
« on: April 30, 2013, 04:49:58 AM »
Several commercially available disk-based diagnostic routines can check the
system by running predetermined tests on different areas of its hardware.
The diagnostic package evaluates the response from each test and attempts
to produce a status report for all of the systemís major components. Like the
computerís self-tests, these packages produce visual and beep-coded error
messages. Figure 3.1 depicts the Main menu of a typical self-booting software
diagnostic package.

This menu is the gateway to information about the systemís makeup and
configuration, as well as the entryway to the programís Advanced Diagnostic
Test functions. You can find utilities for performing low-level formats on
older hard drive types and for managing small computer system interface
(SCSI) devices through this menu. In addition, options to print or show test
results are available here, as is the exit point from the program.
The most common software-troubleshooting packages test the systemís
memory, microprocessor, keyboard, display monitor, and the disk driveís
speed. If at least the systemís CPU, disk drive, and clock circuits are working,
you might be able to use one of these special software-troubleshooting packages
to help localize system failures. They can prove especially helpful when
trying to track down non-heat-related intermittent problems.
If a diagnostic program indicates that multiple items should be replaced,
replace the units one at a time until the unit starts up. Then replace any units
removed prior to the one that caused the system to start. This process
ensures that there are not multiple bad parts. If you have replaced all the
parts, and the unit still does not function properly, the diagnostic software is
suspect.
