AMD is getting ready to ditch its AGESA microcode design in favor of an open-source successor dubbed openSIL, starting with Zen 6. In the meantime, 3mbdeb, a Polish open-source consulting firm, has announced that the first stages of porting openSIL to a consumer Zen 5 motherboard are underway.
The MSI B850-P Pro is the board 3mbdeb chose. If you're an enthusiast for this kind of stuff, you can now take openSIL for a spin before it shows up with AMD's next-generation CPUs, though the firm warns that this is a "proof of concept" that is "not intended for production use." Work on getting openSIL plus Coreboot on the MSI board is based on earlier work surrounding the Gigabyte MZ33-AR1, a server board designed to run AMD's EPYC 9005 series CPUs. AMD published its openSIL initialization code for the aforementioned Turin server chips well before AMD published the same code for its desktop Phoenix CPUs. As a result, the B850-P Pro is benefiting from the development work already put into the aforementioned Gigabyte board.
