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:

  1. 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
