Intel processors with Broadwell cores are very popular in newer higher-end ChromeOS devices.

Factory firmware support for coreboot and SeaBIOS is spotty, but custom firmware is also available for all Broadwell models from John Lewis: https://johnlewis.ie/custom-chromebook-firmware/rom-download/.

Only one firmware update option is currently available for Broadwell models:

RW_LEGACY
- Leaves all stock functionality intact, including the white "OS verification is OFF" screen
- Allows device to dual-boot GalliumOS alongside ChromeOS
- Some models ship with this feature enabled and including a working SeaBIOS
- On some models, includes bugfixes and enables additional functionality such as booting from SD card/eMMC

(for running Linux, you can follow the flashing instructions and install Linux instead of Windows)
