# scripts
|
||||
Scripts for setup/install/firmware update for ChromeOS devices
|
||||
|
||||
setup-kodi.sh facilitates the installation of Kodi on supported ChromeOS devices.
|
||||
|
||||
It allows the user to install a dual-boot setup with either OpenELEC or Ubuntu
|
||||
(with or without Kodi), to set the default OS, and to set the boot timeout on the
|
||||
developer mode splash screen. It also provides for the installation of an updated
|
||||
Legacy BIOS for devices that need it.
|
||||
|
||||
The script also allows the user to flash custom firmware, turning a ChromeBox into a regular PC,
|
||||
and provides for the creation of installation media for OpenELEC and a custom build of
|
||||
KodiBuntu (optimized for Haswell-based ChromeOS devices), though any off-the-shelf OS can be
|
||||
installed (including Windows 8/8.1/10).
|
||||
|
||||
setup-kodi.sh will run on any system with a full bash shell, though the dual-boot related functions
|
||||
are restricted to ChromeOS.
|
||||
|
||||
|
||||
setup-firmware.sh is a slimmed-down version of the above, without the kodi-related parts, and has
|
||||
the same requirements/restrictions as well.
|
||||
|
||||
|
||||
cbox-firmware-update.sh exists solely to update the custom firmware on Haswell ChromeBoxes running
|
||||
OpenELEC, which cannot run the above scripts due to lack of a full Bash shell.
