Leah Rowe 5b2661a485 SeaBIOS/default: Bump to rev b686f460, 28 Jun 2025
This brings in the following changes:

* b686f460 sercon: Fix keycodes for F11 and F12
* b52ca86e docs: Note v1.17.0 release
* a6c8e8bb ahci: Fix hangs due to controller reset

The serial console fix is useful to us, as is the AHCI
fix; the latter was previously mitigated by removing
SeaBIOS's AHCI reset patch.

Upstream realised that the AHCI controllers need to have
a timeout on them when resetting them, because they don't
always react immediately to commands.

This makes the AHCI behaviour more correct, in SeaBIOS.

Libreboot

Documentation: libreboot.org
Support: #libreboot on Libera IRC

Libreboot provides libre boot firmware on supported motherboards. It replaces proprietary vendor BIOS/UEFI implementations, by

  • Using coreboot to initialize the hardware (e.g. memory controller, CPU, etc.) while minimizing unwanted functionality (e.g. backdoors such as the Intel Management Engine)
  • ... which runs a payload such as SeaBIOS, GRUB, or U-Boot
  • ... which loads your operating system's boot loader (BSD and Linux-based systems are supported).

Why use Libreboot, and what is coreboot?

A lot of users who use libre operating systems still use proprietary boot firmware, which often contain backdoors and bugs, hampering user freedom and right to repair.

coreboot provides libre boot firmware by initializing the hardware then running a payload. However, coreboot is notoriously difficult to configure and install for most non-technical users, requiring detailed technical knowledge of hardware.

Libreboot solves this by being a coreboot distribution (in the same way that Alpine Linux is a Linux distribution). It provides a fully automated build system that downloads and compiles pre-configured ROM images for supported motherboards, so end-users could easily fetch images to flash onto their devices.

Libreboot also produces documentation aimed at non-technical users and excellent user support via IRC.

You can check bugs listed on the bug tracker.

You may use Codeberg pull requests to send patches with bug fixes or other improvements. This repository hosts the code for the main build system. The website lives in a separate repository.

Development is also done on the IRC channel.
