New page

Intel processors with Sandy Bridge and Ivy Bridge cores are only used in a few ChromeOS devices.

Factory firmware support for coreboot and SeaBIOS is limited, but custom firmware is available for all Sandy/Ivy Bridge models from John Lewis: https://johnlewis.ie/custom-chromebook-firmware/rom-download/.

There are three firmware update options are available:

# '''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
#* '''''Sandy/Ivy Bridge''': only available for the Google Pixel 2013 (LINK)''
# '''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
#* Bypasses the white "OS verification is OFF" screen
#* 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
#* '''''Sandy/Ivy Bridge''': Enables hardware virtualization extensions and suspend''
