IBM Enhanced Diagnostics
The IBM Enhanced Diagnostics program runs independently of the operating
system. You can use this program to test the hardware components of your
computer. This method of testing is generally used when other methods are not
available or have not been successful in isolating a problem suspected to be
hardware related.
You can run the IBM Enhanced Diagnostics program using the Product Recovery
CD that comes with your computer.
