A quick note on using the livecd with a PS3...
Currently it supports 480i, 576i, 720p, 1080i, and 1080p.
To use the livecd install otheros.self and otheros.bld from the game OS as if you were going to install linux.
Set the PS3 to boot "other os" and reboot. When you get to the kboot prompt type gentoo(+ your desired resolution), for example:
gentoo1080i
To return your PS3 back to the game os type boot-game-os either from kboot or from within Gentoo
aunque la ps3 que tenia para probar se jodio despues de la actualizacion oficial de sony vaya mierda que hizo la descarga me puso la licencia, se actualizo y despues solo dos pitidos y se apaga.
