can i install other os on an external hdd?

[negrito211]

the ps only gives me 10gb which is nothing so i wanna get a external hdd so that i can have plenty of space.i might install win98 or winME i have read the info on that. cause im in the process of making my ps3 my main pc.when i first got ydl i wanted to break it. but once i got everything ready and the hang of it. why have a pc...! im still a noob but linux i think has some better benafits the windows.


thanks
