Install Ubuntu Linux on PS2

view story

http://unix.stackexchange.com – Hello! This is my first question here so I hope it will be good: The title says the most, but i want to say some more. I have searched a lot on google (on other search engines too, but mostly on google), but I only found this video on youtube. But this is not what I wanted. I want to install Ubuntu Linux on the PS2 (as the title says). I am quite new to Linux so I need help with this. I found the model number on the PS2 if that helps: SCPH-50004. My question is: Is it possible to do that and, if so, how? (HowTos)
