LVFS: Switching Branch

Please note: On the StarLite Mk II and Mk III, to switch back to AMI, this must be done with a hardware programmer.

Disable BIOS Lock

BIOS Lock must be disabled when switching from the standard AMI (American Megatrends Inc.) firmware to Coreboot. BIOS Lock is only available in later versions of the firmware, so if you don't see it, please update the AMI firmware first. 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 10 minutes, do not disconnect the charger. This reboot can occasionally stall, so if it's been longer than 5 minutes and the screen is blank, press and hold Ctrl + Alt + Delete and Power for 30 seconds.

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.
