Displayed after any recoverable error message.
Press <F2> to enter SETUP
Optional message displayed during POST. Can be turned off

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.
