"..Coreboot is a replacement for your BIOS / UEFI with a strong focus on boot speed, security and flexibility. It is designed to boot your operating system as fast as possible without any compromise to security, with no back doors, and without any cruft from the 80s. It was originally designed for large super-computers with thousands of nodes, but it will run on your desktop, headless internet server, laptop, tablet or your favorite IoT device."
