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.
