Coreboot installation on Star Labtop Mk IV and Star LabTop Mk III

On Ubuntu 20.04, Ubuntu 20.10, Linux Mint 20.1 and ElementaryOS 6, fwupd 1.5.6 can be installed from the PPA with the following commands in the terminal:

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

Pe Manjaro:

sudo pacman -Sy fwupd flashrom-starlabs

Instructions for other distributions will be added once fwupd 1.5.6 is available. If you are not using one of the distributions listed above, you may be able to install coreboot using a USB Live.

Disable BIOS lock

The BIOS must be disabled when switching from standard AMI firmware to Coreboot. To disable BIOS lock:

1. LabTop must be turned off. Turn it on by holding down the F2 key to access the BIOS settings.

2. When loading the BIOS settings, use the arrow keys to navigate to the advanced tab. Here you will see the BIOS Lock.

3. Press Enter to change this setting from On to Off

4. Then press the F10 key to Save and Exit and then Enter to confirm.

Branch switching refers to switching from AMI firmware to Coreboot or vice versa.

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

fwupdmgr refresh --force

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

fwupdmgr switch-branch

Then you can select which branch you want to use by typing the corresponding number: you will be asked to confirm, press y to continue or n to cancel. Once the switch has been completed, you will be prompted to restart.

The next restart can take up to 5 minutes. Do not interrupt this process and do not disconnect the charger. Once the reboot is complete, you will still receive updates for any branch you use.
