Help =( with fullscreen

[netxhunter]

hi, dudes

i have want to use fullscreen resolution for my 480i sdtv
is arready know that i have to put, 128 (fullscreen) + 1 (480i)= video mode 129

but i found another tutorial that edits the yaboot.conf direferent

1. Edit the file /etc/yaboot.conf and change the line that reads:

   append="rhgb quiet root=LABEL=/1"
   
   ... to ...
   
   append="video=ps3fb:mode:{YOUR VIDEO MODE} rhgb quiet root=LABEL=/1"

or

just put

video=ps3fb:mode:129 rhgb and dont put quiet root label.

or maybe someone could explain to me in detail how to , cause this is mi fisrt time in linux and it is almost another world XD. THANK YOU
