16How to use it?
17==============

19Imacfb does not have any kind of autodetection of your machine.
20You have to add the fillowing kernel parameters in your elilo.conf:
21 Macbook :
22 video=imacfb:macbook
23 MacMini :
24 video=imacfb:mini
25 Macbook Pro 15", iMac 17" :
26 video=imacfb:i17
27 Macbook Pro 17", iMac 20" :
28 video=imacfb:i20
