Noncritical malfunctions cause incorrect results that might not be apparent tothe user. An example of a noncritical error is a memory module failure. If anoncritical error occurs, an error code is displayed, and the testing isstopped. Testing can be continued on a noncritical error by pressing theEsc key.After a successful POST (one in which no critical errors were detected), asingle short beep is generated. The system attempts to load an operatingsystem. The system can be customized for different start (boot) methods.The system’s default startup sequence automatically looks for the operatingsystem files on the hard disk if the files are not found on diskette.Note: Remember that the POST does not test all areas, but only those thatallow the system to operate well enough to run the Diagnostics and Utilitiesprogram.Repair InformationThis chapter contains removal and replacement instructions.Parts/Test Point LocationsThis chapter contains system board layouts and jumper settings.
