@Evv1L @Jumuta Libreboot does not yet auto-download VGA ROMs for T430 though. It does for Dell Latitude E6400.
I have on todo to rewrite the handling of VGA ROMs, so that they can be added for non-Intel GPUs on all currently supported Libreboot hardware.
On T430, Libreboot currently configures coreboot to only use native graphics initialisation, for the Intel GPU. On T430 models with other GPU, the Intel GPU is still present and can be used in this way.
Also, Skulls is a really cool project.
@Evv1L @Jumuta Incorrect. Libreboot's build system automatically downloads update files from Lenovo, to extract things like Intel ME, which is then processed through me_cleaner.
Dumping your factory ROM is still recommended, but you don't need to extract anything from it to build a full Libreboot image.
On Libreboot release ROMs, files like Intel ME are missing but can be added using the same auto-download logic from the build system. See:
https://libreboot.org/docs/install/ivy_has_common.html
We provide SeaBIOS and GRUB.
@Evv1L @Jumuta If you're using Libreboot an a T430 and you boot with SeaBIOS payload, you can still configure use of non-intel GPU if one is present, by modifying cmos.default in flash, using nvramtool with the -C option (Libreboot hardcodes the default so you need -C); and you can add the VGA ROM manually, conforming to name in CBFS: pcivvvv,dddd.rom, where v is vendor ID and d is device ID.
SeaBIOS would then automatically execute it, and if coreboot is configured in this way to use the dGPU.
