0280 Previous boot
incomplete - Default
configuration used Previous POST did not complete successfully. POST
loads default values and offers to run Setup. If the

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.
