Coreboot is a very modular BIOS and runs on a widevariety of computer mainboards. More details are available at: <a href="https://coreboot.org">coreboot.org</a></p><p>Coreboot's main advantage is that of software freedom at the BIOS level. It liberates the computer and allows auser to load multiple types of boot payloads while also allowing us to cripple and neuter the Intel ME.</p><p>Some of the common payloads supported by Coreboot are:</p><ul><li>SeaBIOS - the default payload that ships with your LC230</li><li>Linux - you can embed and load a Linux kernel on the BIOS chip</li><li>Grub - You can also daisy-chain and boot Grub from Coreboot so that you can perform the rest of the boot process via Grub</li><li><code>nvramtui</code> - a utility to configure the Embedded Controller (EC) firmware on thinkpad laptops</li><li><code>memtest</code> - perform memory tests at the BIOS level!</li><li><code>coreinfo</code> - provides low-level information about Coreboot</li><li>TINC - play tetris without even booting an OS!</li></ul><div class="admonition info"><p class="admonition-title">Info</p><p><figure>    <img src="/images/tinc.png" style="height: auto; width: 400px;"/>    <figcaption style="text-align: justify;">        The TINC Coreboot payload - Tetris at the BIOS level.
