HOW TO TURN ON CHROME OS DEVELOPER MODE UPDATE
It is important to be aware of it as one might need to disable the hardware write protection as part of the installation process (to update GBB flags or flash a custom firmware).įor more details see Firmware write protection. The Installation process described on this page tries to cover the method of installing Arch Linux on models without SeaBIOS by flashing a custom firmware.Īll Chrome OS devices features firmware write protection, which restricts write access to certain regions of the flash chip. Take the ChrUbuntu approach which uses the Chrome OS kernel and modules.This is the Modify ROM to run SeaBIOS exclusively option in John Lewis' flash_chromebook_rom.sh script and Flash BOOT_STUB firmware option in MrChromebox's.

This is theoretically a safer approach than flashing the full firmware but there might be some limitations (e.g. This method replaces the stock ChromeOS payload (depthcharge) with SeaBIOS. Flash the BOOT_STUB part of the firmware.Flash a full custom firmware which includes either a SeaBIOS or UEFI payload, and removes all the ChromeOS-specific parts.The easiest way to install/update the RW_LEGACY firmware on your ChromeOS device is via MrChromebox's Firmware Utility Script, which supports the widest range of devices and offers the most up-to-date SeaBIOS builds one can also update the RW_LEGACY firmware manually with Chrome OS' flashrom (requires downloading/compiling your own build), or use John Lewis' flash_chromebook_rom.sh script (no longer supported). This is 100% safe, as it writes to a user-writeable area of the firmware image which is completely separate from/does not affect ChromeOS. If the device supports Legacy Boot Mode, but does not ship with a functional RW_LEGACY payload (or does not ship with one at all), one can flash a SeaBIOS payload to the RW_LEGACY part of the firmware.One of the following approaches can be taken in order to install Arch Linux on Chrome OS devices which did not ship with SeaBIOS as part of the installed firmware: These models require a 3rd party RW_LEGACY firmware to be loaded for Legacy Boot Mode to be functional. Models with an Atom-based SoC (Baytrail, Braswell, Apollolake) have Legacy Boot Mode capability, but do not ship with a RW_LEGACY/SeaBIOS payload (that part of the firmware is blank). Models with a Core-i based SoC (Haswell, Broadwell, Skylake, KabyLake) mostly ship with a functional Legacy Boot Mode payload updating to a 3rd party build can provide bug fixes and additional features. SeaBIOS behaves like a traditional BIOS that boots into the MBR of the disk, and from there into standard bootloaders like Syslinux and GRUB. It is enabled by the SeaBIOS payload of coreboot, the open-source firmware used for all Chrome OS devices (with the exception of the first generation of Chromebooks and a few early ARM models). Legacy Boot Mode has a dedicated firmware region, RW_LEGACY, which is designed to be user-writeable (hence the 'RW' notation) and is completely separate from the ChromeOS portion of the firmware (ie, it is safe to update and cannot brick the device). 4.6.5 Mapping in Gnome with gsettings setĪll recent Intel-based Chrome OS devices (starting with the 2013 Chromebook Pixel) feature a Legacy Boot Mode, designed to allow the user to boot Linux.4.6.3.1 Alternate xbindkeys configuration.4.3.1.1 What to do if your touchpad or touchscreen is not supported?.4.3.1 Touchpad and touchscreen kernel modules.3.2.2 Accessing the superuser shell when logged into ChromeOS.3.2.1 Accessing the superuser shell without logging into ChromeOS.2.1 General hardware recommendations and remarks.1.1.1 Models without Legacy Boot Mode/SeaBIOS.
