Thanks to Google's sponsorship, we've been able to significantly improve the project's Quality Assurance process by creating a completely automated and distributed testing environment. Every single commit results in BIOS images being built for all mainboards, and tested on real hardware located all over the world. So whenever you want to download a LinuxBIOS image, you can now know that it works on a reference machine before flashing it to your system.
