For the first time, a retail AMD Ryzen AM5 motherboard is running AMD openSIL and Coreboot thanks to Dasharo firmware from 3mdeb, offering users a genuine open-source alternative to proprietary BIOS on the MSI PRO B850P WiFi. Here's how the breakthrough was achieved and what it means for enthusiasts.
Open-source firmware has finally breached the walls of mainstream AMD desktop hardware. The MSI PRO B850P WiFi, a retail AM5 motherboard, now boots with AMD openSIL and Coreboot-no closed BIOS required. This is not a lab demo or a proof-of-concept on obscure reference boards. It's a real, purchasable product, and it works.
3mdeb, the Polish firmware consultancy behind Dasharo, has delivered what AMD itself has not: a Coreboot and openSIL port for a consumer Ryzen motherboard you can actually buy. Until now, AMD's own openSIL efforts were limited to internal reference platforms, leaving enthusiasts locked out of open firmware on retail hardware. That lock has been picked.
Come si è arrivati a questa svolta
The journey began with 3mdeb's earlier work on server-class boards, notably the Gigabyte MZ33-AR1 for AMD EPYC. Building on that, the team spent months porting Dasharo-built on Coreboot and openSIL-to the MSI B850P WiFi. The first public Dasharo builds for this board appeared only recently, but the impact is immediate: for the first time, end users can flash and run open-source firmware on a Ryzen AM5 desktop system.
Deploying Dasharo on the MSI board is refreshingly straightforward. While AMD's ROM Armor blocks BIOS writes from the OS, MSI's FlashBIOS feature sidesteps this: copy the Dasharo image to a USB drive, insert it into the designated port, and press the physical FlashBIOS button with the system powered off. No external programmer required-unless you want to go that route. After a brief hiccup with initial boot failures, 3mdeb quickly resolved the issue, and flashing now works as intended.
Funzionalità e limiti attuali
There's a catch: openSIL's current proof-of-concept only supports Phoenix-based Ryzen 8000 series APUs, such as the Ryzen 7 8700G and Ryzen 5 8600G. While the MSI PRO B850P WiFi hardware is compatible with Ryzen 7000, 8000, and 9000 CPUs, openSIL's scope is still limited. Enthusiasts hoping to run the latest Ryzen 9000 chips will have to wait for AMD to expand support.
For those within the supported CPU range, the experience is solid. Testing with a Ryzen 7 8700G showed stable performance and no major regressions compared to closed firmware. Security-minded users can even order pre-assembled systems with Dasharo pre-flashed and tamper-proof sealed, directly from 3mdeb's webshop.
Implicazioni per il mercato e la sicurezza
This development is a direct challenge to the closed, opaque firmware that dominates the PC industry. For users who demand transparency, auditability, and control, Dasharo on the MSI PRO B850P WiFi is a tangible alternative. It's a move that echoes the push for open hardware seen in other segments-much like the reported earlier shift in mini PC expectations with the GEEKOM IT13 MAX.
However, the openSIL project's limited CPU support is a reminder that open firmware on consumer hardware is still a work in progress. AMD's reluctance to officially support retail boards or expand openSIL's compatibility leaves much of the Ryzen ecosystem behind. The ball is now in AMD's court: will they open the gates further, or will open firmware remain a niche for the most determined users?
3mdeb's achievement is more than a technical milestone-it's a statement. By making open firmware accessible on a mainstream AMD desktop platform, they've exposed the artificial barriers imposed by proprietary BIOS vendors. The success of Dasharo on the MSI PRO B850P WiFi proves that open-source firmware is not just possible, but practical, for real-world systems. If AMD and other vendors continue to drag their feet, they risk ceding trust and loyalty to those who actually deliver transparency and user empowerment. The message is clear: the era of closed firmware is running out of excuses.
