Chapter Two - Testing
On units with MS-DOS installed, diagnostic tests are provided as a tool to verify the op-
eration 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’s Product Repair & Customization De-
partment (see Chapter 4).
Note
Remove any device drivers or memory resident programs (TSRs) in-
stalled on the system before running Xycom diagnostic tests. If you do
not, unexpected failures may occur.
Note
You must hook up a monitor before running any tests.
Make sure the BIOS setup menus are configured properly (factory set configuration).
To enter the Setup Menu:
1.
Press
F2
after the POST RAM test has completed.
2.
Make the necessary changes by following directions on the screen.
3.
Press
ESC.
4.
Press
ENTER
twice to save the Setup and exit.
Refer to your CPU manual for more information on the BIOS setup menus.
