So I have this 2006 Mac Pro 1,1 that I’ve had laying around and I wanted to put my old Nvidia 1030 into it, along with Windows 10 for a newer (stronger?) home machine.
So I burnt the downloadable ISO from Microsoft onto a DVD, tried to boot it up and got this:
I got stuck at this “Select CD-ROM Boot Type : ” prompt, which you can’t type anything into. Apparently it’s a common and known issue with 64bit boot code, as the older Intel Apple Mac’s are of course 32bit only. So there is a fix, you have to use something called “oscdimg” to rebuild the ISO with a 32bit friendly loader.
So first I just used 7zip to extract the downloaded ISO, and then create the new 32bit ISO with the following:
oscdimg -n -m -bc:\temp\Windows10\boot\etfsboot.com c:\temp\Windows10 c:\temp\LegacyBootWindows10dvd.iso
And yes, it boots!
Now what about those special ‘bootcamp’ drivers? Obviously under Windows 10 there is no nice way to get the ones you want. And what about which model/download package to get?
Then I found Brigadier!
It’ll probe your hardware type and grab the drivers for you!
