## Building coreboot
### Preliminaries
Prior to building coreboot the following files are required:
* Intel Flash Descriptor file (descriptor.bin)
* Intel Management Engine firmware (me.bin)
* ITE Embedded Controller firmware (ec.bin)
The files listed below are optional:
- Splash screen image in Windows 3.1 BMP format (Logo.bmp)
These files exist in the correct location in the StarLabsLtd/blobs repo on GitHub which is used in place of the standard 3rdparty/blobs repo.
### Build
The following commands will build a working image:
```bash
make distclean
make defconfig KBUILD_DEFCONFIG=configs/config.starlabs_starbook_tgl
make
```
## Flashing coreboot
```eval_rst

#### **Requirements:**
* fwupd version 1.5.6 or later
* The battery must be charged to at least 30%
* The charger must be connected (either USB-C or DC Jack)
* BIOS Lock must be disabled
* Supported Linux distribution (Ubuntu 20.04 +, Linux Mint 20.1 + elementaryOS 6 +, Manjaro 21+)
**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. **1.5.6** or greater will work.
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-git 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, it is possible to install coreboot using a Live USB.
**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**
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:
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.
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.
