Previous boot incomplete - Default
configuration used
Previous POST did not successfully complete. POST
loads default values and offers to run Setup. If the
failure was caused by incorrect values and they are not
corrected, the next boot will likely fail. On systems with
control of wait states, improper Setup settings can also
terminate POST and cause this error on the next boot.
Run Setup and verify that the wait-state configuration is
correct. This error is cleared the next time the system is
booted.
