Previous boot incomplete-Default configuration used
description:
solution:
The previous POST did not complete successfully. The POST loads defult 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 can also terminate POST and cause this error on the next
boot.
Run Setup and verify the wait-state configuration is correct. This error is cleared
the next time the system is booted.
