So… got Chromium OS installed on your old machine and want flash compatibility?  Read on.

The version of Chromium OS used is ArnoldTheBat’s Version.  This may differ with different versions.

First make sure you are logged into the Chromium OS system, then do the following:

Open Chrome browser

Press CTRL + ALT + T to bring up the terminal tab

Type in shell and hit return

Type in sudo su then hit return

The password is: password

When you are in the shell screen (slightly different to the terminal screen) type in the following commands that are highlighted in black.  After every line, hit return:

#Prepare the filesystem for writing
mount -o remount, rw /
cd /opt/

#Download the data (all one line)
wget --no-check-certificate -O "data.tar" ""

#Unzip the data
tar -xf data.tar

#Making the directories
mkdir -p /usr/lib/mozilla/plugins/
mkdir /usr/lib/cromo/
mkdir /opt/google/chrome/pepper/

#To install mp3,mp4
cp /opt/data/ /usr/lib/cromo/ -f
cp /opt/data/ /opt/google/chrome/ -f
cp /opt/data/ /usr/lib/mozilla/plugins/ -f

#To install PDF
cp /opt/data/ /opt/google/chrome/ -f

#To install Flash
cp /opt/data/ /opt/google/chrome/pepper/ -f
cp /opt/data/manifest.json /opt/google/chrome/pepper/ -f
cp /opt/data/ /opt/google/chrome/pepper/ -f

#To delete the temporary files and restart UI
rm -rf /opt/data/
rm /opt/data.tar
restart ui

And there you go.  Head over to whatever site you want and enjoy your flash 🙂
