sorry, I have seen it coming, I had over the weekend very little time for OS X.

So to the AMD Radeon HD8240, the graphics card works without graphics acceleration as far as I can estimate that, here the desired ioreg file and a few pictures.



what does not work:

Ethernet card RTL8111

Wifi BCM4313 and Intel WM3945ABG

sound card


I will try to resolve the problems in the next few days.

This is a Kabini family card


Can u upload your ioreg file from registry explorer ?


i'd like todo a research on this card type

Yes that's a Kabini AMD Radeon HD8240 R3-Series. But you can bring to work with any other graphics card. The procedure is relatively simple an efi-string in to org.chameleon.boot.plist, a modified dsdt with graphic injection and driver patch. That's it.


or use clover bootloader and test with fake id and efi string that should also work.
