The following documentation describes the process of Dasharo open-source firmware update. The update process may be different, depending on which firmware version is currently installed on your device.
You can check your current firmware version with the following Linux command.
sudo dmidecode -t bios | grep Version
Alternatively, it can be checked in the Dasharo Setup Menu when booting the device.
First, determine your device version with the following Linux command.
sudo dmidecode -t system | grep "Product Name"
Alternatively, it can be checked in the Dasharo Setup Menu as well.
Device name based on the previous output and the following table.
|Product Name output||Device name|
|NV4XMB,ME,MZ||NV4x 11th Gen|
|NS50_70MU||NS5x/7x 11th Gen|
|NV41PZ||NV4x 12th Gen|
|NS50_70PU||NS5x/7x 12th Gen|
Depending on the firmware version, there may be manual steps required to ensure
that the firmware can be updated.
11th Gen devices starting from version v1.5.0
12th Gen devices starting from version v1.7.0 have support for Firmware
Update Mode. For older versions, please continue with
the Updating older versions section.
Firmware Update Mode
If the currently installed Dasharo version supports Firmware Update Mode, follow the steps outlined in the generic Firmware Update documentation.
Check out our YouTube video for a demonstration of Firmware Update Mode.
Updating older versions
First, ensure that UEFI Secure Boot has been disabled.
Boot to the Dasharo Tools Suite. We recommend the network boot option.
In the main menu of Dasharo Tools Suite, select option
5to proceed with the installation of the firmware update.
In case you want to know more about the firmware update option in Dasharo Tools Suite, please check out the features section of the dedicated Dasharo Tools Suite documentation page.
This update method is for advanced users only and is not recommended for regular end users.
Ensure that the firmware protections are disabled (1) in
Dasharo Security Options.
BIOS boot medium lock and
Enable SMM BIOS write protection should
be unchecked. UEFI Secure Boot
must be disabled as well (uncheck
Attempt Secure Boot if
Current Secure Boot State does not say
Disabled). To apply changes, you
will need to reboot.
- These options were introduced in v1.5.0 for TGL models and v1.7.0 for ADL models. You can skip these steps if you are using an older firmware version.
Follow the manual update procedure described in the DTS firmware update documentation.
Please make sure you that you update the BIOS firmware and the EC firmware respectively.
