<hr />
<div>GalliumOS currently does not support UEFI, however it is possible to get it working with some time and effort. We opted to exclude UEFI support for GalliumOS because was no acceptable UEFI payload for the target hardware of GalliumOS. There is now a coreboot UEFI payload available on Chrome hardware, and GalliumOS does plan to add UEFI support.<br />
<br />
UEFI support is interesting to GalliumOS because it could bring better Bay Trail support (see [[Support/BayTrail]]), support for Braswell (see [[Support/Braswell]]), potential support for some ARM models (see [[Support/ARM]]), and potentially even support for other non-Chrome hardware that could be considered as possible targets for GalliumOS. UEFI support is also interesting because it could potentially reduce boot time and possibly even bring it very close to parity with ChromeOS.<br />
<br />
GalliumOS currently has no specific plans for how we plan to implement UEFI, however it seems likely that we will go about it in a very different way from Debian or Ubuntu. UEFI allows booting the Linux kernel directly, without the need for any bootloader, which could save us a lot of boot time by skipping GRUB entirely.</div>Coolstarhttps://wiki.galliumos.org/index.php?title=Support/UEFI&diff=1012Support/UEFI2016-07-22T00:02:43Z<p>Coolstar: Updated for UEFI firmware release</p>

Factory firmware support for coreboot and SeaBIOS is spotty, but custom firmware is also available for all Broadwell models from John Lewis: https://johnlewis.ie/custom-chromebook-firmware/rom-download/.<br />
<br />
Only one firmware update option is currently available for Broadwell models:<br />
<br />
# '''RW_LEGACY'''<br />
#* Leaves all stock functionality intact, including the white "OS verification is OFF" screen<br />
#* Allows device to dual-boot GalliumOS alongside ChromeOS<br />
#* Some models ship with this feature enabled and including a working SeaBIOS<br />
#* On some models, includes bugfixes and enables additional functionality such as booting from SD card/eMMC<br />

<hr />
<div>Factory firmware on many Chromebooks and Chromeboxes can run Linux out of the box.<br />
<br />
Custom firmware is also available, which can fix factory firmware bugs and/or add the ability to boot Linux to those models that otherwise cannot.<br />
<br />
Check [[Hardware Compatibility]] and the appropriate [[Support]] page to determine the status of your model.<br />
<br />
There are several custom firmware options available, depending on your Chromebook/box model class, and the features you require: <br />
