Chromium OS is the open-source development version of Chrome OS, one of Google's operating systems (OS). Chromium OS is based on the Linux kernel and uses Google's Chromium browser as its principle user interface. As a result, Chromium OS primarily supports web applications.
Chromium's architecture is three-tiered, consisting of "three major components:
- The Chromium-based browser and the window manager
- System-level software and user-land services: the [Linux] kernel, drivers, connection manager, and so on
Installable, working versions of Chromium OS have been produced and made available for download primarily by hobbyists. Some devices come with Chromium OS preinstalled as their main operating system.
By May 2010, compiled versions of the work-in-progress source code had been downloaded from the Internet more than a million times. The most popular version, entitled "Chromium OS Flow", was created by Liam McLoughlin, a then 17-year-old college student in Manchester, England, posting under the name "Hexxeh". McLoughlin's build boots from a USB memory stick and included features that Google engineers had not yet implemented, such as support for the Java programming language.
While Google did not expect that hobbyists would use and evaluate Chromium OS ahead of its official release, Sundar Pichai, Google vice president of product management said that "what people like Hexxeh are doing is amazing to see." Pichai said the early releases were an unintended consequence of open source development. "If you decide to do open-source projects, you have to be open all the way."
Hexxeh's work continued into the following year. He announced "Chromium OS Lime" in December 2010, and in January 2011, released "Luigi", an application designed to "jailbreak"/"root" the Google Cr-48 "Mario" prototype hardware and install a generic BIOS. The developer made the builds available in virtual machine format on March 13, 2011. With no official build of Chromium OS forthcoming from Google, Hexxeh's "vanilla" nightly builds of Chromium OS were the principal resource for people wanting to try Chromium OS. Hexxeh stopped uploading his builds on April 20, 2013.
In May 2011, Dell Computer also released a new build for the Dell Inspiron Mini 10v netbook, following up on an earlier build released almost 18 months earlier. The build did not support audio, but was bootable from a USB drive.
In July 2012, Chromium Build Kit was released. It automatically compiles a developer build and installs Chromium OS on a USB drive.
Some devices have shipped with Chromium OS preinstalled. They include the Kogan Agora Chromium Laptop by the Australian company Kogan and the Xi3 Modular Computer, introduced by the company of the same name.
In June 2011, ISYS Technologies, based in Salt Lake City, sued Google in a Utah district court, claiming rights to the name "Chromium" and, by default, Chromebook and Chromebox. The suit sought to stop Google and its hardware and marketing partners from selling Chromebooks. The suit was later dismissed and, as part of an undisclosed settlement between Google and ISYS, ISYS abandoned its trademark efforts.
