A hardware modder on Overclock.net reports successfully booting Windows 11 on Intel's OEM-only Core 9-273PQE "Bartlett Lake" CPU using a standard Asus Z790 LGA1700 motherboard after crafting custom BIOS microcode and patches that spoof early initialization as Raptor Lake. The proof-of-concept highlights both the platform's latent compatibility and the limits of accessibility, since Bartlett Lake chips remain unavailable to typical consumers despite interest in an all–performance-core desktop release.
