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:
- Power on the device.
- While the device is booting, hold the
DELETE
key to enter the UEFI Setup Menu. - Enter the
Dasharo System Features
menu using the arrow keys and Enter. - Enter the
Dasharo Security Options
submenu. - Verify the state of the
Lock the BIOS boot medium
option - if the option is chosen, pressSpace
and thenF10
to save the changes. - 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.
