3 Basic System Test
What is Tested
❒ Keyboard tests:
•
Keyboard controller
•
Keyboard clock line
•
Keyboard data line
❒ VESA Video memory test
❒ USB test
❒ Other tests:
•
Basic serial port test (does not include data transfer – this is an
advanced test)
•
Basic parallel port test (does not include actual printing – this is
an advanced test)
Each test listed above is performed only if it is appropriate for your
PC’s configuration. For example, if your PC does not have a SCSI
controller, or no SCSI device is connected to the SCSI controller, no
SCSI tests will be done.
Furthermore, a component test will only be performed if the
component was correctly detected in the hardware detection phase.
For example, if you have recently installed an IDE hard disk drive and
it was not detected during the hardware detection phase, the hard disk
drive will not be tested. (For more information about hardware
detection, refer to page 11.)
NOTE DiagTools does not test components that have not been detected.
However, we recommend that you continue with the basic system test
to verify that the underlying components are functioning correctly.
