Thank you very much for your help, as soon as I finish current projects , I will try the solution that you suggested and I'll publish the results of my tests on this page. (my clients would not be pleased if I can not work because of a computer crash, they do not understand ) Here is my Hardware ID:

Exactly .. so far Apple has never released FirePro drivers. I have not had time to do tests on my graphics card yet.. This is my iMac system booted in Win7x64 via Boot Camp The hardware id seems to be the same as the rest of the technical characteristics with the exception of Subvendor. How would I know if the Mac OS X drivers for Apple's 6970m will also work on the M8900 VBIOS modified version even before trying to flash the VBIOS? You know, prevent is better than cure.. I had already thought of this possibility, but I do not think is healthy for the chip card and also impractical for me that often switch from one system to another. This is another great idea, shame that I have no knowledge to be able to face such a sophisticated transformation. I look forward to a new opinion after you have assessed the data of the screenshot above. In any case thanks for your time!

Hello svl7 & Star Forge, I am new to the forum and I joined to find a way to do the softmod on my iMac 27 2011. I am a technical illustrator and to achieve many of my designs often use CAD software like Solid Edge, SolidWorks, Inventor and 3DVIAComposer. Your solution is spectacular for owners of personal computers that use mainly traditional Microsoft operating systems. In my case I could still apply the changes to the BIOS, but lose the ability to restart in Mac OS X, since up to now there is no driver for the FirePro series (up to now, Apple does not install on their systems FirePro graphics cards). I already tried in other forums, but I realized that if you do not have the updated patchscript compatible with the related driver, you have little chance of success. Since I can not find suitable patchscript, I was wondering if you could give me some advice on how to find one or suggest a safe way to apply the method You described to flash back and forth (Win7 x64 > Mac OS X) without destroying the graphic chip (replace the iMac's graphics card could be very expensive). Probably in my case I have to wait for the release of a new patchscript, however I also wanted to ask the opinion of a professional like You. Latest AMD FirePro M8900 driver from Autodesk 8.83.5.3_Win7_A02_R304146 iMac 27 2011 specifications: 3.4GHz Quad-Core Intel Core i7 16GB 1333MHz DDR3 SDRAM - 4x4GB 1TB Serial ATA Drive AMD Radeon HD 6970M 2GB GDDR5 Mac OS X Leopard 10.6.8 Windows 7 Ultimate x64 (Boot Camp 3.3) I hope I was clear and I thank you again for the wonderful guide You wrote.
