Coreboot 24.08 debuted on Monday night as the newest feature release for this open-source system firmware project that allows replacing the proprietary BIOS/firmware on many different platforms. With Coreboot 24.08 comes more than 900 patches from 130+ developers in continuing to support new motherboards and making other improvements.

Coreboot 24.08 introduces new functions to better address potential overflows within SMI handlers. There are also new helper functions around Flattend Device Tree (FDT). Meanwhile Coreboot's WiFi driver now supports Bluetooth Regulator Domain Settings. The PS/2 keyboard driver also supports Do Not Disturb and Accessibility keys.

A new payload available with Coreboot 24.08 is the LeanEFI payload. The LeanEFI payload serves effectively as a translator from Coreboot to UEFI. LeanEFI is able to take Coreboot tables and translate them into UEFI interfaces that in turn can then be used by the likes of LinuxBoot. LeanEFI though is quite lean and doesn't support EFI variables or other select EFI features.

Coreboot 24.08 also brings many updates to its Autoport tool, x86_64 support for LibPayload, an hda-decoder utility to dump decoded HDA default configuration registers, SMBIOS tables support for ARM64 platforms, WiFi 7 802.11be enablement, support for Radio Frequency Interference (RFI) mitigation within the WiFi driver, and other updates.

There are also a number of new motherboards supported by Coreboot 24.08. There is the usual flow of new Google Chromebook designs being supported, some old ASRock motherboards being enabled, two Intel reference motherboards being enabled, the Star Labs Lite Mk V, and System76 addw4 / darp10 / darp10-b / oryp12 laptops.
