IBM Enhanced Diagnostics
IBM provides programs that you can run to diagnose hardware problems and
some software problems. Several utility programs that provide helpful
information about your computer are also included. The user interface for
running these diagnostic and utility programs is provided by PC-Doctor.
The IBM Enhanced Diagnostics program will isolate your computerhardwarefrom
software that was preinstalled (or that you have installed) on your hard disk.
These programs run independently of the operating system and are generally
used when other methods are not available or have not been successful in
isolating a problem suspected to be hardware related.
