+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

- high: number of pages allowed for queueing by all TCP sockets.
