Chapter Two - Testing; Preparing For The Tests - Xycom 3500 Series Manual

Chapter Two – Testing
On units with MS-DOS installed, diagnostic tests are provided as a tool to verify the op-
eration of system hardware functions. If any of these tests fails, either you do not have
the correct default setting or there is a failure. Check the default settings and run the tests
again. If another failure occurs, contact Xycom Automation's Product Repair & Cus-
tomization Department (see Chapter 5).
Remove any device drivers or memory resident programs (TSRs) in-
stalled on the system before running Xycom Automation diagnostic
tests. If you do not, unexpected failures may occur.
The diagnostic disk does not provide an option to test a CD-ROM drive.
