Published release of free bootable firmware Libreboot 26.10, which received the status of a stable release. The project develops a ready-made assembly of the Coreboot project, which provides a replacement for proprietary UEFI and BIOS firmware, responsible for initializing the CPU, memory, peripherals and other hardware components, with minimization of binary inserts.
Libreboot aims to create a system environment that allows you to do without proprietary software as much as possible, not only at the level of the operating system, but also the firmware that provides booting. Libreboot complements Coreboot with tools to simplify use by end users, creating a ready-made distribution that can be used by any user without special skills.
Compared to the previous stable release, support has been added
222 Google Chromebook models based on Intel and AMD processors, 9 editions of Purism Librem 13/14/15/Mini laptops, as well as Samsung Lumpy and Stumpy models, ThinkPad X301, ThinkPad X270 and ThinkPad X280
In addition, support has been added for the Dell OptiPlex 5050 SFF and Dell OptiPlex 3040 Micro PCs, the Supermicro X11SSH-F motherboard.
Compatibility with new devices was achieved thanks to the integration of payload based on EDK2 from the coreboot distribution MrChromebox, which made it possible to provide full support UEFI and ReBAR (PCIe Relocatable BAR). ReBAR support solved problems with modern video cards with more than 4 GB of memory. EDK2 (UEFI implementation) is enabled by default even on older devices such as the ThinkPad X200 and T500, and ReBAR is disabled by default due to problems with output in the libgfxinit library
on systems with Intel GPUs.
UEFI support has been tested when booting Windows 10/11, 9front (fork of Plan 9), Linux distributions with UKI or systemd-boot, OpenBSD with EFI boot loader and GPT partitions, FreeBSD in UEFI mode and RedoxOS. ReactOS won’t boot due to lack of UEFI support. Separate use of GRUB and SeaBIOS has been deprecated, but for backward compatibility, EDK2 has built-in EFI assemblies of GRUB and SeaBIOS, called by pressing ESC at boot. EDK2 includes MemTest86+ and iPXE.
Significantly expanded support for motherboards for AMD Fam15h processors, such as the KGPE-D16. To initialize such boards, a coreboot fork from the 15h.org project is used, which uses the AMD Agesa (AMD Generic Encapsulated Software Architecture) initialization protocol code, previously published by AMD.
By default, the HAP (High Assurance Platform) bit is set during assembly to disable Intel ME. Updated versions of Coreboot (dated September 18, 2026), EDK2 26.09.2, GRUB 2.16 and SeaBIOS (dated July 28, 2026).
