Hey,
I got a MacPro1,1 running El Capitan with my ASUS GTX 750 Ti by using Pike's boot.efi, flashing the TI, putting it onto the second PCI Bus, putting the old, no longer supported Graphics Card onto the first Bus, zapping PRAM, installing the Web drivers via VNC and changing the lane split in the Expansion Utility. That has one, big downside. Both cards have 8 Lanes and the rest of the lanes only have very few lanes. The old card needs to be in Slot 1, so I cannot give it only one lane.
This would be the target:
25 Lanes:
1 Lane on Bus 1
16 Lanes on Bus 2
4 Lanes on Bus 3
4 Lanes on Bus 4
Is that somehow possible? The PCi Expansion Utility does not have that option. Maybe via IOReg? I hope that some of you know that problem and can give me a tip.
Regards
