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.
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.
