I've installed Chromium on an old Asus 1000HE that had Windows 7 installed and not being used. It took some work to create the installation USB and then getting the 1000HE to boot from it, but I prevailed and I am writing this using the Chrome OS on this Asus. #

The installation is based on Neverware's CloudReady, which is available for free to install on older computers.#
