Chapter 2 - Testing
On units with MS-DOS, Xycom Automation provides diagnostic tests to verify the
operation of the system hardware functions. If any of these tests fail, 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 & Customization Department (see Chapter 5).
Note
Remove device drivers and memory resident programs (TSRs) that are installed on the
system before running Xycom diagnostics. If this step is not completed unexpected
failures may occur.
Make sure the BIOS setup menus are configured properly (factory-set configuration).
To enter the BIOS setup menus:
• Press
F2 after the POST RAM test has completed.
• Make the necessary changes by following directions on the screen.
• Press ESC
.
• Press ENTER twice to save the settings and exit.
Refer to the CPU manual for more information on the Setup Menu.
