The process involved dumping the original BIOS using pico-serprog on an RP2040-zero, applying deguard to neutralize the Intel Management Engine, and adapting the existing X280 port. Key challenges included accidentally knocking off a tiny SMD capacitor during flashing (requiring a Digikey order), and diagnosing NVMe/WiFi dropouts caused by incorrect PCIe clock request (CLKREQ) pin assignments — the X270 uses CLKREQ2 for WiFi rather than CLKREQ1 as on the X280. After correcting the PCIe allocations and overridetree, GRUB, NVMe, and WiFi all worked under Guix System. Changes are being upstreamed to the Coreboot project. ## Full article daily.dev links to this article rather than hosting it.
