Building off Coreboot 25.03 is now the availability of Coreboot 25.06 for further enhancing this open-source system firmware project that continues to see new hardware improvements — predominantly for Google Chromebook devices but also more Intel platforms and other hardware — as well as new capabilities to further rival proprietary BIOS solutions.
Coreboot 25.06 brings an improved boot splash screen framework to open up new possibilities for better branding / vendor logo options and other styling enhancements. Bluetooth and WiFi wireless devices meanwhile now support Power Reduction Request (PRR) ACPI DSM functions for enhancing power management of Bluetooth/WiFi devices. Coreboot 25.06 is also now compatible with the GCC 15 compiler and has a variety of other code improvements.
On the hardware side, Coreboot 25.06 finally enables support for Intel Xeon 5th Generation “Emerald Rapids” server processors, which is a generation behind the current generation Xeon 6 Granite Rapids and Sierra Forest processors.
Also on the Intel side is Coreboot 25.06 improving support for next-generation Core Ultra Series 3 “Panther Lake” SoCs. Coreboot already had basic Panther Lake support in place but is now better off with the new 25.06 release.
Coreboot 25.06 also brings support for some new motherboards, but as is often the case is mostly new Google Chromebook targets. At least there is some new NovaCustom, Star Labs, and System76 hardware. Plus some old ASUS targets and from MiTAC Computing (TYAN).
