Re: uEFI grub2 on Raspberry Pi, Alexander Graf from Opensuse

... folder with three files in it, bcm2837....dtb, ns2-svk.dtb, vulcan-eval.dtb. I assume the vulkan file has the mesa/graphic stuff in it.

Re: of BIOS and OS

Yes , even Windows 10 "IoT Core" has to use the firmware. Firmware is not software-specific but hardware-specific. All OS on desktop PCs will use the BIOS/EFI/UEFI.

All OS on the Raspberry must use start.elf and bootcode.bin etc.
