Intel processors of the Haswell architecture are very popular in 2013/2014-era ChromeOS devices.
Factory firmware support for booting legacy OSes via SeaBIOS is common, but custom firmware is also available for all Haswell models as well -- see Firmware.
There are three firmware update options available:
- RW_LEGACY
- Leaves all stock functionality intact, including the white "OS verification is OFF" screen
- Allows device to dual-boot GalliumOS alongside ChromeOS
- Most models ship with this feature enabled and including a working SeaBIOS
- On some models, includes bugfixes and enables additional functionality
- Haswell: Most models ship with this feature enabled, but a few are buggy
- BOOT_STUB
- Bypasses the white "OS verification is OFF" screen
- Removes the ability to run ChromeOS natively, creating a small risk of bricking your device
- Leaves the “REFRESH + POWER” functionality of the stock ROM intact
- If you engage this key sequence, device will reboot and try to run ChromeOS Recovery (which will fail)
- This process will repeat on every boot until you disassemble the device and briefly disconnect the battery
- Full ROM
- Installs a complete ROM containing a coreboot build and a working SeaBIOS
- Removes the white "OS verification is OFF" screen
- Removes the ability to run ChromeOS natively, creating a small risk of bricking your device
- Adds full hardware support for virtualization (vmx / VT-x)
- This option is the most comprehensive and fixes many bugs and/or idiosyncrasies associated with the stock firmware
Model-Specific Notes
ASUS Chromebox, 2014 (PANTHER) / HP Chromebox, 2014 (ZAKO)
- Factory legacy boot firmware bug prevents use of attached USB devices at boot, including keyboard
- While installation is possible with factory firmware, it is less than ideal.
- Custom firmware does not have bug; update
RW_LEGACY. See Installing/Panther.
