Flashing

The flash chip cannot be flashed internally when running vendor firmware, and must be flashed externally using a programmer of your choice.

Steps on how to open the chassis and get access to the mainboard are described in the hardware maintenance manual. Follow the steps shown from “Removing the computer cover” until step 1 of “Replacing the storage drive”.

The SPI flash should be easy to identify and the location is shown in the image below. See the datasheet and flashing firmware tutorial for more information.
