Fiddly and annoying, but it works.

Then you can install any GPU you want for Windows. Even ones with no EFI32 will work fine in Windows. ALl of the RAM shows up and once you get Bootcamp drivers in you can use volume keys and use Bootcamp control panel in Windows to choose different startup disk.

I have a 2006 MacPro Tower upgraded from 1,1 to 2,1 and Yosemite 10.10 installed via the ( pre-patched Piker-Alpha bootable Yosemite installer ) with a unflashed Gigabyte R9 280X REV2 card outputting 4096x2160 on my 4k projector.

I was able to install Windows 7 Ultimate 64bit on my early 2011 macbookpro 8,2 bootcamp partition and then load the bootcamp drivers via my 10.6.6 install disc without a problem since this machine is 64bit. I then use Winclone to copy that install onto the MacPro tower's NTFS partition. It booted up, it worked!!!

I needed to go this route because of the following: You can load the newest version of Windows 7 64bit onto a MacPro NTFS partition, but Bootcamp will not allow you to load its files onto that partition as it must see the 32bit Efi. This can be a huge pain, as you may want to see your HFS partitions, drives, and have the drivers for all the Mac hardware/peripherals. Well.. I can now see my mac drives and use the bootcamp control panel in Windows 7 64bit to reboot into Mac OS 10.10 Yosemite!!
No BSOD! No Bootcamp files to disable. No glitches.

I'm really happy about this as Windows 7 Ultimate 32bit is limited to 4gb ram usage but was listing only 1.99gb usable for me.

I'm glad that I did not have to go through all of those steps listed in this link:

I put Yosemite on my 1,1 using Piker-Alpha as well, then loaded Windows 7 Ult 64-bit via Bootcamp Assistant. It did get fussy about drivers, but I already had the 1,1 drivers on a USB stick from an earlier 32-bit Bootcamp installation under 10.6. IIRC I just fed those to Windows as a driver update post-install and the obvious driver issues like volume control cleared up. (There's a sleep/resume issue that I assume is due to me updating the BIOS to 2,1 but not the SMC (yet).)

That sounds great! But how did you install the Bootcamp drivers from the Snow Leopard DVD? Is it possible to just put in the DVD and install them under Windows?

Thank you very much in advance!

Best regards,
