Coreboot 25.09 was released this evening as the latest feature update to this open-source solution common to Google Chromebooks and other select motherboards/systems as an alternative to proprietary BIOS / system firmware.

This open-source firmware solution brings support for 19 more motherboards, improved boot functionality, performance enhancements, new boot mode detection capabilities, and other low-level enhancements.

Coreboot's AMD firmware tool "amdfwtool" brings better support for the latest-generation AMD EPYC 9005 "Turin" platform with better address mode handling and EFW structure parsing. There is also updates to Coreboot payloads like SeaBIOS, U-Boot, EDK2, and LinuxBoot.

New motherboard support with Coreboot 25.09 includes:

- ASROCK SPC741D8-2L2T/BCM

- GIGABYTE GA_H81M_D2W

- Google BlueyH

- Google Caboc

- Google Kinmen4ES

- Google Lapis

- Google Matsu

- Google Moonstone

- Google Ojal

- Google Padme

- Google Quartz

- Google QuenbiH

- Google Tarkin

- HP 260 G1 DM

- HP Compaq Pro 6300 SFF/MT

- HP ProDesk 600 G1 SFF

- Intel Ptlrvp4es

- Lenovo ThinkPad T480

- Lenovo ThinkPad T480s

Of that list, standing out as usual are many new Google Chromebook ports. Plus the ThinkPad T480/T480s support in mainline will excite some.

The Intel Ptlrvp4es is a reference platform for Intel Panther Lake. Intel continues to be active in the Coreboot space as part of helping Google Chromebook design wins.

The ASROCK SPC741D8-2L2T/BCM support is interesting as it's a server motherboard for 4th and 5th Gen Xeon Scalable processors. Still prior generation but not too far behind.
