The openSIL PR includes fixes for Phoenix desktop CPUs, MMIO handling, Promontory21 chipset initialization, and missing SMU/USB/GFX initialization. The engineer confirmed successfully booting Ubuntu 26.04 and Windows 11 on an AMD B850 chipset using coreboot. Corresponding Coreboot PRs include an initial tree for the MSI PRO B850-P WIFI motherboard. This follows 3mdeb's earlier release of the first open-source firmware for a modern AMD Ryzen AM5 platform under their Dasharo firmware flavor. ## Full article daily.dev links to this article rather than hosting it.
