7. Updating the uEFI BIOS
BIOS updates are typically delivered as an update CD ISO image. This ISO image needs just
to be burned to a CD and booted. Follow the menu for updating the uEFI BIOS. For further in-
formation refer to the update CD documentation.
7.1 uEFI BIOS Fail-Over Mechanism
The CP6003-SA/RA/RC has two SPI boot flashes programmed with the uEFI BIOS, a standard
SPI boot flash and a recovery SPI boot flash. The basic idea behind that is to always have at
least one working uEFI BIOS flash available regardless if there have been any flashing errors
or not.
7.2 Updating Procedure
An update CD is provided for flashing the latest uEFI BIOS on the standard SPI boot flash. The
standard SPI boot flash can also be programmed with the latest uEFI BIOS via the kflash -p
uEFI Shell command.
Note: To have the same content in both SPI boot flashes, clone the standard SPI boot
flash to the recovery SPI boot flash. For further information, please refer to Chapter
6.2.7, kflash uEFI Shell Command.
7.3 uEFI BIOS Recovery
In case of the standard SPI boot flash being corrupted and therefore the board not starting up,
the IPMI controller boots the board from the recovery SPI boot flash if the DIP switch SW1
(CP6003-SA) / SW3 (CP6003-RA), switch 2 is set to OFF. On the CP6003-RC, the configura-
tion resistor R759 must be set to Open in order for the IPMI controller to boot the board from
the recovery SPI boot flash.
For further information about the boot configuration, refer to the respective chapters in the
board’s user guide or contact Kontron for further assistance. Information about the boot config-
uration for the CP6003-SA is provided in the CP6003-SA User Guide, Chapter 4.1, for the
CP6003-RA in the CP6003-RA/RC User Guide, Chapter 4.1 and for the CP6003-RC in the
CP6003-RA/RC User Guide, Chapter 4.2.
7.4 Determining the Active Flash
Sometimes it may be necessary to check which flash is active. On the AMI Aptio-based uEFI
BIOS, the information is available using the kboardinfo uEFI Shell command. For further in-
formation, refer to Chapter 6.2.2, kboardinfo uEFI Shell Command.
