Not totaly correct! you do need 3.1Roms in order to run OS3.1+ but you can softkick it! this means what the roms does will be done via software! this works ok (all though i dont like it) and it will give you a litle bit slower bootup! another negative thing is that if you happen to crash your HD or decided to format it will need to set up this once again and then you will need to install OS3.0 first then find the softkicker application of your choice and install this and then 3.1! if i were you id buy 3.1roms but your free to your own opinion.
