Setup Instructions for Chromium OS on Toshiba Tecra M10

Here are similar instructions for the Dell Latitude 2120 units

Step 1: Downloading and Preparing the Operating System

Download the latest 64-bit nightly build courtesy of ArnoldTheBat.

Open a terminal and use diskutil to find the usb key (min 4GB key) device name.

diskutil list

You'll likely see somthing like this:

MacBook-Pro:~ user$ diskutil list
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *500.1 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:          Apple_CoreStorage                         499.2 GB   disk0s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3
/dev/disk1
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *2.0 GB     disk2
   1:             Windows_FAT_32 USB DISK                2.0 GB     disk2s1

Instead of using disk1, we'll use rdisk1 for the dd command as it's a bit faster. Here's a discussion as to why.

sudo dd if=Desktop/chromiumos_image.img of=/dev/rdisk1 bs=4m
password: *

Wait...and wait...and wait.

You can check the progress with:

kill -SIGINFO Process-ID

Where Process-ID is the process id you would find by running a ps -ef command.

Step 2: Install the OS

Boot from the USB Key and follow these instructions courtesy of the Chromium Project to access the command prompt.

After your computer has booted to the Chromium OS login screen, press [ Ctrl ] [ Alt ] [ F2 ] to get a text-based login prompt.

The username is chronos and the password is password

Customize the image to the M10 with touchpad and flash fixes. These are courtesy of Matt Brash who made this step really easy for you.

sudo su
curl -L http://l.brash.ca/m10fix | bash

Your ui will get restarted at the end of this script.

After your computer has booted to the Chromium OS login screen, press [ Ctrl ] [ Alt ] [ F2 ] to get a text-based login prompt.

The username is chronos and the password is password

Run the following command to install the operating system to the hard drive:

/usr/sbin/chromeos-install --dst /dev/sda

Shut down the computer and remove the USB Key.

That should do it.
