A remarkable breakthrough in the hardware community has demonstrated that Intel's new Bartlett Lake processor architecture — exemplified by the Core 9 273PQE — can be booted on a standard Z790 motherboard. An anonymous community member modified the BIOS of an Asus Z790-AYW OC Wifi motherboard to make the processor, originally designed for Edge and industrial applications, compatible with desktop platforms. The modification enabled the system to successfully complete the Power-On Self-Test (POST), indicating fundamental compatibility with existing hardware.
Despite reaching the POST screen, the system crashed shortly afterward with a black screen, suggesting lingering firmware or driver issues. The Core 9 273PQE is part of Intel's new Bartlett Lake lineup, which features a Pure P-core design — differing from the traditional hybrid architecture that combines Performance (P) and Efficiency (E) cores. This new approach is tailored to optimize performance and power efficiency in specific use cases such as Edge computing and industrial systems, where high single-threaded performance is critical.
The successful boot on a motherboard designed for Intel's 14th and 15th generation processors opens new possibilities for hardware enthusiasts and businesses alike. It suggests that users may be able to upgrade to the new CPU generation without purchasing new motherboards — a development that could save significant costs. Experts acknowledge the project is still in early stages, but reaching the POST phase represents a promising foundation for future progress.
The community is already working on additional BIOS modifications and driver updates to enable operating system boot. If these challenges are overcome, this achievement could influence Intel’s compatibility strategy for future processor generations and extend the lifespan of existing Z790 platforms. This success also highlights the crucial role of the open-source community in advancing hardware technologies, even when they are initially targeted at niche markets.
