Libreboot 26.01rev1 t420_8mb, variant seagrub_libgfxinit_txtmode_svenska patched with the real Intel VBIOS (vgabios.bin, both PCI IDs 8086,0166/8086,0126), SeaVGABIOS removed. SeaBIOS + GRUB payload, text-mode init, Swedish GRUB keymap.
Supersedes release 20260718 (corebootfb variant): that image hung on Windows 11 boot and, once patched with the VBIOS, gave Kali Linux colour flicker at startup — both are graphics-handoff artifacts of corebootfb + a real VBIOS fighting over INT 10h. This txtmode + VBIOS image is what the original 2024 custom coreboot build used, and it boots Windows 11 and Linux (Kali, Fedora) cleanly with no flicker.
Prepared with ./mk inject (neutered Intel ME via me_cleaner, onboard NIC MAC injected) plus a cbfstool patch adding the vendor VBIOS and removing vgaroms/seavgabios.bin. Built and reproduced two ways — manually and via the docker/ build in this repo — with matching sha256sums. Flashed internally 2026-07-21, boots and runs on the machine (i7-3632QM).
This is the exact image on the chip — usable as a recovery image via the FT232H + SOIC8 clip procedure in the README.
