Press <F1> to resume, <F2> to Setup
This is displayed after any recoverable error
message. Press the F1 function key to start the
boot process or the F2 function key to enter
BIOS Setup and change any settings.
Press <F2> to enter SETUP
This is not an error message. Instead, it is an
optional, informational message that is
displayed during the controller’s power-on
self-test (POST). Note that the display of this
message can be turned off in BIOS Setup.
Previous boot incomplete -
Default configuration used
The previous power-on self-test (POST) did not
complete successfully. The POST then loads
the default BIOS configuration values and offers
to run BIOS Setup. If the failure was caused by
incorrect BIOS values that were set and they
are not corrected, the next boot will also likely
fail. Therefore, ensure that all configuration
values are re-set correctly in BIOS Setup. This
error should then be cleared the next time the
controller is booted.
