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:

Display or save test results
Run thorough tests to introduce additional test options to provide extra
information about the failed device(s)
