In addition to 3mdeb firmware engineers porting AMD openSIL and Coreboot to a Gigabyte EPYC Turin server motherboard, the staff at this firmware consulting company are also porting AMD openSIL and Coreboot to a modern Ryzen AM5 desktop motherboard. They continue making good strides with that quest for the first readily-available Ryzen desktop motherboard with open-source system firmware.
Back in February was the announcement by 3mdeb that they are bringing Coreboot and openSIL to a consumer AM5 motherboard and in turn their commercial Coreboot-based Dasharo firmware offering.
The MSI PRO B850-P is a current-generation, readily-available ATX motherboard for current Ryzen AM5 processors. It was widely available for ~$180 USD but given the ongoing pricing squeeze in the industry, as of writing it’s currently selling for around $235 USD from the likes of Amazon (affiliate link).
In anticipation of this AMD openSIL and Coreboot port, I had already bought an MSI PRO B850-P for testing and readying to free that closed-source BIOS in favor of openSIL+Coreboot when available.
3mdeb on Friday published their latest blog post to outline their ongoing bring-up of Coreboot and the AMD Phoenix openSIL code. Some of this bring-up is benefiting from the simultaneous work they are doing with the Gigabyte MZ33-AR1 server motherboard port. Their latest work includes on bringing up MPIO, SMU, NBIO, and continuing work on graphics bring-up. There is almost successful OS boot with this port.
