  1. Hi arnoldthebat
    Thanks for all the good work, as a result of it i have managed to get Chrome OS working on an old MSI CR620 laptop :) The only thing however that does not work is the wifi, this appears to use an Intel Centrino N6300 AGN wireless card. Any chance you might be able to tell me how I could add the drivers if indeed they are available?
    Thanks again.

    1. I forgot to say that I am using your special build 7451.0.2015_09_12_1720. If I do an ls on /lib/firmware i can see all the iwlwifi files that the card needs listed, but if I try to modprobe -r iwlwifi the modprobe command is not recognised?

  2. Hello, I’m trying to install the U special edition to hard drive but when I click alt+Ctrl and T and type install it tells me it’s not a recognized command. I also tried /user/shin/chromeos-install but didn’t work. Is there a way to install it to hard drive?


  3. Never mind the webcam… do you think Google Audio/Video plugin works under ChromeOS (re: webcam driver?)

    That is all I really need…

    Great work on the builds, I’ll go back and re-check that previous build that worked OOTB with everything else, see if I cannot get webcam working? It may be impossible without V4L module built tho…

    You have a great day… and remember – everyone here loves what you are doing!!!
