Over time, this system evolved from a simple browser-running machine into a robust OS capable of running Android apps, Linux applications, and sophisticated web apps, while maintaining the same commitment to security, rapid updates, and speed found in those early beta versions. Conclusion
This is the precise version milestone. A "1.0" or sub-1.0 version branch reflects the ecosystem in late 2009 and 2010. During this phase, Google was actively testing the operating system's stability, refining the window manager, and ensuring underlying hardware drivers functioned correctly.
As web applications grew more complex and demanded greater memory, the 32-bit architecture became a bottleneck. Google eventually phased out 32-bit x86 support entirely. Modern iterations, such as ChromeOS Flex, explicitly require an x86-64 Intel or AMD processor alongside a minimum of 4GB of system RAM to deploy. Google Chrome OS Linux i686 1.0.628 OEM Beta x86
The 1.0.628 OEM Beta, released in 2010, was one of the first publicly available versions of Chrome OS. Built on a Linux i686 architecture, this beta version was specifically designed for x86-based systems. The "OEM" label indicated that this version was intended for original equipment manufacturers (OEMs) to test and integrate Chrome OS into their devices.
The designation signifies that this build was tailored for manufacturers to test hardware compatibility, such as Wi-Fi chips, screens, and touchpads, before finalizing the hardware. Over time, this system evolved from a simple
In early 2010, several "OEM Beta" or "Cherry" builds circulated on file-sharing sites and forums. These used a versioning scheme (like 1.0.x) that preceded the official Google Chrome OS release on the CR-48 prototype in late 2010. Technical Breakdown of the Name
To achieve this, the OS was a read-only squashfs image. The user partition was essentially a cache container. If you bricked the OS, hitting Ctrl+Alt+Shift+Refresh would re-download the entire OS image from Google back when servers were at chromeos-images.corp.google.com (long defunct). During this phase, Google was actively testing the
The i686 architecture, however, was eventually phased out. As noted in a GitHub issue for the Chromebrew project, "The last official release of i686 Chrome OS (excluding CloudReady) was released in 2017. That means the lack of security patches and an older system base, which makes it more and more unreliable in daily use". Today, Chrome OS has moved entirely to x86_64 and ARM, leaving the i686 builds as historical artifacts.
To run this specific historical version, you generally need to use a recovery-style installation process. ChromeOS 90 | Specs, reviews and EoL info - InvGate
The identifier "1.0.628" indicates an early, pre-release Beta build, specifically targeted for testing. The "i686" and "x86" tags identify it as being built for older 32-bit architecture processors, which were standard in the netbooks intended for the system's debut.
: The Linux i686 core was stripped of all unnecessary drivers, legacy printing subsystems, and server protocols. It included only the vital code required to run on targeted x86 netbook chipsets. This minimalism is what allowed early test machines to boot to a login screen in under 8 seconds.
