Getting Developer Hardware
Device manufacturers and silicon vendors who have systems or developer boards that can be used for Chromium OS development will be posting information about their development systems/boards, pre-release builds that work with the hardware, and directions for obtaining hardware in the discussion group chromium-os-dev.
Developers, manufacturers, and vendors have summarized their experiences with developer boards and systems in the Developer Hardware page, which contains a list of systems that run pre-release builds of Chromium OS.
There is also information on official Chrome OS devices.
