This string of text refers to an extremely early, pre-release, and now obsolete version of Google’s operating system. Here is a breakdown of what each part means and why you likely encountered it.
Modern Chrome OS is renowned for its security model, featuring a "Verified Boot" process that checks the integrity of the system partition upon startup. In build 1.0.628, this security infrastructure was likely in a rudimentary state. As an OEM Beta, the firmware signature verification may have been relaxed to allow developers and manufacturers to modify partitions without bricking the device. This trade-off provided flexibility but exposed the system to potential rootkit attacks, a common vulnerability in early beta operating systems. Google Chrome OS Linux i686 1.0.628 OEM Beta x86
Two years after this build, i686 was deprecated. In 2012, Google announced that all future Chromebooks would run 64-bit (x86_64) or ARM. The Atom netbook was dying, replaced by the Celeron 847 (64-bit) and the Exynos 5250 (ARM). This string of text refers to an extremely
Build 1.0.628 became obsolete instantly. Furthermore, because Chrome OS updates were automatic, any OEM that actually used this beta on a test device would have auto-updated past it within a month. The only surviving copies are: In build 1
What made 1.0.628 special were the OEM-specific touches. Some builds had a hidden “Manufacturer Testing” page accessible via chrome://oem. There, you could run memory tests, flash the BIOS, or recalibrate the battery. Another weird artifact: pressing Ctrl+Alt+T opened a terminal, but it wasn't crosh—it was a full, unfiltered bash shell with root privileges. Yes, Google gave OEMs root in an unverified shell. That’s how early this was.
