Mac Pro 1.1 El Capitan Install

  

Free teeth whitening app. 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.

I created a USB disk with a bootable El Capitan as per this documentation. Plug-in your USB key on a turned-off computer. Start your Mac, press immediately OPTION (aka ALT) Select the Orange icon (aka a USB stick) labelled El Capitan. If it does not detect it after 10 sec and you only see your hard-drive. Try another USB port and wait 10 sec again. It sounds like you have a mac pro 1,1 like mine with Quad core 2.66GHz processors. It is correct about the 32 bit EFI on these systems but there is a workaround with a re-written bootloader for the MacPro 1,1 that will enable you to run El Capitan (last OS before Sierra) flawlessly on your Mac Pro. Some of the Mac systems that do not meet up with the minimum hardware requirements for Mac OS X El Capitan include: iMac 4.1 to 6.1, MacBook 1.1 to 4.1, MacBook Pro 1.1 to 2.1, MacBook Air 1.1, Mac Mini 1.1 to 2.1, Mac Pro 1.1 to 2.1, and Xserve 1.1 to 2.1.

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:tempWindows10bootetfsboot.com c:tempWindows10 c:tempLegacyBootWindows10dvd.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?
