4.4 TEST SELECTION MENU
The Test Selection Menu selections vary
according to the configuration of the computer
being tested. You can elect to run one test, a
combination of tests, or all of the tests. When
you run multiple tests, the program proceeds
automatically from one test to the next until
testing is completed successfully. When running
the program in the unattended mode, tests that
require operator intervention are not performed.
For complete system checkout, each test should
be run at least once in the attended mode. The
diagnostic tests are:
□ Processor
□ Memory
□ Keyboard
□ Parallel Interface
□ Video
□ Diskette Drive
□ Monochrome Video Board
□ Asynchronous Communications Interface
□ Modem Communications
□ Fixed Disk Drive
□ Fixed Disk Drive Backup (Tape)
□ Enhanced Color Graphics or Video Graphics
□ Auxiliary Input Interface
NOTE: If error codes appear as you run the
tests, refer to Chapter 5, ERROR MES-
SAGES AND CODES, for a list of error
codes, code descriptions, and the proce-
dures recommended for correcting the
error condition.
The following paragraphs describe these tests.
Processor
The Processor test verifies the main processor,
coprocessor (if installed), configuration (CMOS)
memory (if applicable), processor support logic,
and speaker.
