What is imacfb?
===============
This is a generic EFI platform driver for Intel based Apple computers.
Imacfb is only for EFI booted Intel Macs.
Supported Hardware
==================
iMac 17"/20"
Macbook
Macbook Pro 15"/17"
MacMini
How to use it?
==============
Imacfb does not have any kind of autodetection of your machine.
You have to add the fillowing kernel parameters in your elilo.conf:
Macbook :
video=imacfb:macbook
MacMini :
video=imacfb:mini
Macbook Pro 15", iMac 17" :
video=imacfb:i17
Macbook Pro 17", iMac 20" :
video=imacfb:i20
