Hello,

I have just updated my mac pro 1,1 to Yosemite Via pikes- alpha all is running smoothly bar the graphics . i removed the 7300GT and installed a GT630 (worked fantastically with lion). which i could not boot from (black boot up as expected but then no desktop).

With the 7300 back in i can see both cards in the system profiler . Is there a way to boot from the 630 on its own or force it to switch gfx cards once booted

Edit: I have also tried booting the mac with a windows 5770 with know luck surely i should be able to work with one of the cards
