Other diagnostic programs on the Software Selections CD
The Software Selections CD supplied with your computer also contains
diagnostic programs designed specifically for certain operating systems.
Because these versions work with the operating system, they not only test the
hardware, but also analyze certain software components of your computer.
These diagnostic programs are especially useful in isolating problems related to
the operating system and device drivers.
