    Has anybody tried installing Lion GM on a MacPro1,1?

    I currently have Windows 7 (64 bit) installed, and so I'm worried Lion could somehow harm the Boot Camp installation.

    Never fear. It doesn't damage it. As for upgrading the Boot Camp 4.0 drivers on a Mac Pro 1.1, it isn't officially supported. The auto run Setup.exe programme won't even offer installing the Boot Camp drivers, so you'll need to do it yourself by going to the Drivers folder and then running, from an elevated command prompt, the 64-bit *.msi installer.

    Great. I did the .msi trick to install the SL (3.x) Boot Camp Drivers a year ago when first setting up Boot Camp.

    Can you confirm that the same trick will work for BC4.0?

    Sorry I'm just really anxious about not being locked out of Boot Camp:)

    Yes, I can confirm it.

    I've installed the GM and I'm running the BC assistant - but when I choose the option to download the files, the indicator makes it about 1/3 of the way and just sits there forever. Just a fluke I hope? I can't seem to get it to finish...

    edit: worked after another reboot...

    I also have the Bootcamp 4.0 drivers working fine on Mac Pro 1,1 only problem is the nice GUI for the volume control, cd eject etc is gone. Also you can no longer eject CDs with F12.

    I'm in this boat right now. I tried the .msi trick and I get an error message saying that the installation requires elevated privileges, and to install from setup.exe. How do I "sudo" in windows?
