  • Only available on Star Labtop Mk IV

fwupd 1.5.6 or later
To check the version of fwupd you have installed, open a terminal window and enter the below command:

fwupdmgr --version

This will show the version number. Anything higher than 1.5.6 will work.
fwupd version
On Ubuntu 20.04, Ubuntu 20.10, Linux Mint 20.1 and elementaryOS 6, fwupd 1.5.6 can be installed from our PPA with the below terminal commands:

sudo add-apt-repository ppa:starlabs/ppa
sudo apt update
sudo apt install fwupd

On Manjaro:

sudo pacman -Sy fwupd flashrom-starlabs

Instructions for other distributions will be added once fwupd 1.5.6 is available.

Disable BIOS Lock
BIOS Lock must be disabled when switching from the standard AMI (American Megatrends Inc.) firmware to Coreboot. To disable BIOS Lock:

1. Start with your LabTop turned off. Turn it on whilst holding the F2 key to access the BIOS settings.
2. When the BIOS settings load, use the arrow keys to navigate to the advanced tab. Here you will see BIOS Lock.
3. Press Enter to change this setting from Enabled to Disabled

Disable BIOS Lock

4. Next, press the F10 key to Save & Exit and then Enter to confirm.

Switching Branch

Switching branch refers to changing from AMI firmware to Coreboot, or vice versa.

First, check for new firmware files with the below terminal command:

fwupdmgr refresh --force

Then, to change branch, enter the below terminal command:

fwupdmgr switch-branch

You can then select which branch you would like to use, by typing in the corresponding number:
Switch Branch
You will be prompted to confirm, press y to continue or n to cancel.

Once the switch has been completed, you will be prompted to restart.

Installed Coreboot
The next reboot can take up to 5 minutes, do not interrupt this process or disconnect the charger. Once the reboot is complete, that's it - you'll continue to receive updates for whichever branch you are using.

You can switch branch at any time.
