ArnoldTheBat's special build of Chromium OS is just fabulous!

Chromium OS inside my old mini laptop - fantastic!

Chromium OS is an open source version of Google's Chrome OS. ArnoldTheBat is a developer offering a special version of Chromium OS. I decided to give it a go. Now I'm a very pleased owner of an old mini laptop with automatically updating Chromium OS on hard disk! In addition localization works out of the box! Read below the steps I took.

Edit: Auto-update is not working just yet (in the end of December 2014).

My Acer Aspire One ZG5 running Chromium OS!

Prepare your USB stick and boot PC from USB

• Download the 7-zipped image from Arnold the Bat's web site
• Unzip the image
• Write Chromium OS image on USB stick (8 GB), Win32DiskImager works just fine on Windows
• Boot your PC from USB stick (in my case F12 helped)
• Choose your language and network
• Sign in with your Google account

Install Chromium OS on hard disk

• Type Ctrl-Alt-T
• Type shell
• Type sudo su (password is "password" without citations)
• Type cd /usr/sbin
• Type ./chromeos-install --dst /dev/sda (sda is my hard disk)
• Wait until the installation is ready, if asked answer yes and your hard disk is wiped
• Type shutdown -h now
• Hope for the best!

Boot your PC and sign in

• Remove USB stick
• Boot your PC
• Choose your language and network
• Sign in with Google account

If you want to see the memory consumption, type Ctrl-Alt-T, type shell and type top (q for quit). In my case I only have 1 GB RAM. However Acer Aspire One ZG5 leaves me 10 MB free memory! ZG5 boots in approximately 20 seconds. Not bad!

When I was signing in Chromium OS promised all updates take action automatically. That's very nice and comfortable! I guess my laptop downloads updates from ArnoldTheBat's server, not from Google.

So far I'm very happy with Chromium OS!
