Enhanced Pre-Boot System Assessment (ePSA)
diagnostics
The ePSA diagnostics (also known as system diagnostics) performs a complete check of your hardware. The ePSA is embedded with the
BIOS and is launched by the BIOS internally. The embedded system diagnostics provides a set of options for particular devices or device
groups allowing you to:
•
Run tests automatically or in an interactive mode
•
Repeat tests
•
Display or save test results
•
Run thorough tests to introduce additional test options to provide extra information about the failed device(s)
•
View status messages that inform you if tests are completed successfully
•
View error messages that inform you of problems encountered during testing
NOTE:
Some tests for specific devices require user interaction. Always ensure that you are present at the computer terminal
when the diagnostic tests are performed.
