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:

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

    • 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

Model-Specific Notes

Acer C740, Acer C910 and Acer CB5-571 (auron_paine and auron_yuna)

  • Full ROM flash is possible

A full ROM is available from CoolStar:

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

    • Bypasses the white "OS verification is OFF" screen
    • Installs a complete ROM containing a coreboot build and a working SeaBIOS
    • Removes the ability to run ChromeOS natively, creating a small risk of bricking your device
    • Will wipe out all product data
    • This option is the most invasive and may include bugs or idiosyncrasies that the stock firmware does not
    • Fixes Graphics issues associated with the RW_LEGACY
    • Fixes several issues related to ACPI
    • Allows booting Linux, Windows and even Mac OS!
