I'm not interested in enabling the dGPU. If I was interested in that I wouldn't try to install via EFI.

I would be interested in getting Windows 7 x64 to work. I think I have everything in line for it to work, including pure GPT and MSR, however I can't find the PCI registers for the Bridge and ATI 5870. How do I locate these and link these together?

Mac Pro 5,1

Thank you

Does someone test the new windows 8 drivers provided with the new bootcamp from 10.8.3. I could not test because the new manager said my iMac is only compatible with Win7 ! Liar !

Does someone could uploaded the Windows 8 files ?

I tried it on my iMac 2011, everything works fine except there's still no sound.

What about your graphic card (ATI ? /NVIDIA ? /INTEL ?) ? Does it work without exclamation mark or other problem ? Which driver are you using (the one provided by Apple or for the manufacturer ?) You are in EFI mode ?

Does someone are tested the Leshcat’s Catalyst Version ? (http://leshcatlabs.net/index.php/category/unifl/)

Boot Camp 5.0 is out. Just wonder if BC has any support for Windows 8 in EFI mode.

Model Identifier: MacBookAir2,1 (mid 2009)
The EFI is 64bit as shown by

Iioreg -l -p IODeviceTree | grep firmware-abi .... "firmware-abi" = <"EFI64">

There is no official support for my model, as stated here, hence I think the bootcamp package of Windows drivers will probably not contain all the drivers that I need. That may not be a problem because I might be possible to get them elsewhere.

Will there be any difference i the end result (except the windows drivers) if the Windows8 installation media is created in bootcamp compared to for example the Microsoft Windows7/8 USB Tool?

Previously I have managed to run windows8 32bit with no problems.

I have tried to prepare a USB flash drive formatted in both FAT32 and HSF with the windows 8 x64 installation files - but it didn´t boot using Apple´s bootloader.

Is there anything left to try?

Alright its bee awhile that I make post on this thread.

Since I got new MBP 13.3" 2012, I decided to install Windows 8 in EFI mode

Installing is very easy, no magic required (nothing has been changed from MSDN ISO image)

Bootcamp 5.0 driver installed fine as well.


Conclusion.
Everything works "EXCEPT" sound

even brightness can be changed (not like win7 + efi) but sound just not work!

Anybody have found solution for this problem?

I have a 13" rMPB, latest one released this year. Would your efi method work for mine? If so, could you link/describe the process for dualbooting OSX? Install win8 like normal and partition OSX,then install OSX? Thanks a ton!!

Is it possible to run Windows 7 in EFI mode on Mac Pro 2009 ?

I was able to run Windows 8 successfully, but I hate it :/

Have you managed to install Windows 8 to a 2009 MBA in EFI mode? I'm currently trying...
