Witness the pivotal shift in firmware as 9elements ports Coreboot and AMD openSIL to the Framework 16 and 13 laptops. This in-depth analysis explores the technical challenges of memory training, the move towards open-source silicon initialization (openSIL), and what this means for the future of modular hardware, security, and AMD platforms from Zen 4 to Zen 6.
In an industry often defined by closed-source black boxes, a quiet revolution is underway within the BIOS/UEFI firmware space. The movement toward open-source firmware is gaining unprecedented momentum, and its latest beachhead is one of the most beloved devices in the modular computing movement: the Framework Laptop.
Consulting firm 9elements has confirmed it is actively porting Coreboot alongside AMD’s new open-source silicon initialization library, openSIL, to the first-generation Ryzen 7000 series Framework 16.
This development isn't just a routine firmware update; it represents a fundamental shift in how the x86 architecture initializes hardware, moving away from the proprietary AGESA framework toward a transparent, auditable future.
Why Coreboot + openSIL Matters for Enterprise and Enthusiasts
For the uninitiated, Coreboot is a highly specialized open-source firmware project designed to initialize hardware and hand off control to a bootloader or operating system. Its primary value proposition is speed, security, and minimalism.
However, its adoption has historically been hampered by the need for "blobs"—proprietary binary code from CPU vendors required to initialize their complex silicon.
This is where AMD’s openSIL (Open-Source Silicon Initialization) changes the game. Unlike the legacy AGESA (AMD Generic Encapsulated Software Architecture), which is a monolithic binary, openSIL is designed to be integrated as open-source code directly into firmware projects like Coreboot.
The Strategic Shift from AGESA to openSIL
The work being done by 9elements is a practical proof-of-concept for AMD’s long-term roadmap. While AMD has committed to supporting AGESA through the Zen 5 generation, Zen 6 (and subsequent next-gen platforms) will rely on openSIL for production-ready initialization.
This transition makes the current porting efforts on Framework hardware critical for validating the library’s stability.
Vendor: AMD
Legacy Technology: AGESA (Binary Blobs)
Future Technology: openSIL (Open Source)
Target Platform: Zen 6 and beyond
Key Benefit for Coreboot: Native integration without proprietary blobs.
Dissecting the Port: From Framework 16 to Framework 13
Alicja Michalska of 9elements has been sharing technical insights regarding the challenges of bringing up the AMD "Phoenix" SoCs (found in the Ryzen 7040 series) with openSIL.
The current work is focused on the Framework 16 Gen1, but the roadmap clearly includes porting the same solution to the Framework 13 "Lotus" motherboard.
The Technical Hurdles: Memory Training
According to recent commit logs and code reviews published by 9elements, the project is currently in the "early hardware initialization" phase. The most complex obstacle at this stage is memory training.
Memory training is the process where the firmware dynamically tunes the electrical parameters of the RAM to ensure stable communication with the CPU.
Doing this reliably within an open-source context—without access to the same proprietary tuning tables used by AMI or Insyde BIOS—requires meticulous reverse engineering and collaboration with AMD's openSIL team.
"Exciting to see this work happening for the older AMD Phoenix based Framework 16 and then Framework 13 laptops. Hopefully similar support will also end up coming for the newer Strix Point hardware in time too."

The Broader Ecosystem: 3mdeb and Enterprise Adoption
9elements is not operating in a vacuum. This movement is part of a larger industrial trend toward firmware transparency. Parallel efforts are being conducted by another prominent consulting firm, 3mdeb, which is simultaneously working on Coreboot + openSIL integration for entirely different hardware segments.
This diversification is crucial for proving the scalability of openSIL:
Consumer Platform: 3mdeb is targeting an MSI AM5 Ryzen motherboard, bringing open-source firmware to the desktop enthusiast market.
Enterprise/Data Center: 3mdeb is also porting the stack to a Gigabyte AMD EPYC 9005 server motherboard.
This dual-pronged approach demonstrates that openSIL is not merely a hobbyist experiment but a viable enterprise solution capable of handling the stringent requirements of server infrastructure.
Frequently Asked Questions (FAQ)
Q: What is Coreboot?
A: Coreboot is an extended open-source firmware project that replaces proprietary BIOS/UEFI. It initializes the hardware (CPU, RAM, peripherals) extremely quickly and is known for its security features and auditability.Q: What is AMD openSIL?
A: AMD openSIL (Open-Source Silicon Initialization) is a new library from AMD, written in open-source code, that handles the low-level initialization of their CPUs. It is designed to replace the proprietary AGESA framework.Q: Will this work on my current Framework 13 with Ryzen 7000?
A: The initial work is targeting the Framework 16 and Framework 13 Gen1 (Ryzen 7000 series). While it is currently a work-in-progress (WIP) and not ready for end-users, 9elements aims to bring functional support to these specific models.Q: Why does this matter for security?
A: By replacing proprietary binary blobs with auditable, open-source code (openSIL) within Coreboot, security researchers and system administrators can verify exactly what the firmware is doing, reducing the risk of hidden backdoors or vulnerabilities.Conclusion: A Blueprint for the Future
The collaboration between Framework (championing repairability) and 9elements (championing open firmware) sets a new benchmark for the industry. It proves that modern, complex AMD platforms can be initialized transparently.
While the work is still nascent—dealing with the intricacies of memory training and code integration—the successful porting of Coreboot + AMD openSIL to the Framework 16 will serve as a blueprint for other hardware manufacturers. It signals to the market that open-source firmware is not a compromise, but an upgrade.
