Firmware update

The following documentation describes the process of Dasharo open-source firmware update. If your device is currently flashed with the proprietary firmware please refer to Initial deployment documentation.

For simplicity of the update process, we recommend using Dasharo Tools Suite.

Before starting the update procedure be sure to disable Dasharo BIOS Boot medium lock:

  1. Power on the device.
  2. While the device is booting, hold the DELETE key to enter the UEFI Setup Menu.
  3. Enter the Dasharo System Features menu using the arrow keys and Enter.
  4. Enter the Dasharo Security Options submenu.
  5. Verify the state of the Lock the BIOS boot medium option - if the option is chosen, press Space and then F10 to save the changes.
  6. Reboot the device to properly apply the changes.

Only the RW_SECTION_A partition of the flash needs to be updated. Flash it using the following command:

flashrom -p internal -w [path] --fmap -i RW_SECTION_A

This command also preserves Dasharo UEFI settings and the boot order.
