I got the EFI string for my first graphics card in PCIe slot 1, and a EFIstring for my second graphics card in PCIe slot 2... if I put just one in, and boot with that video card only in, it works fine.

 

But if I have a both plugged in, then I get black screens when I boot. How I can I merge these two together?

See my post in this thread. You must turn the hex strings back into plists, merge the plists, then turn back into hex.

 

How do I I turn them back into plists? I tried copying the long hex stream into a new file with textedit, and saving it as a hex file, but when I used gfxutil to change from hex to plist, it told me it was an invalid hex file.

Here's the two strings:

How do I turn them back into plists so I can merge them?

Those hex strings must have started out as plists originally. How did you generate them?

 

gfxutil -i xml -o hex carda.plist carda.hex

 

Or something like that; I forget exactly. But I dumbly deleted the carda and cardb plist files, and can't get them back from the hex codes.

Okay, turns out it was because textedit was adding .rtf to the end of my hex file... did it with nano and it worked.

 

But I still get a kernal panic if both cards are plugged in... but if I do either one of the cards with the right EFIstring it works...

 

Here's the plist for the first card:

Here's the second video card:

I converted that merged plist into hex codes, put in my boot plist, but boom! kernal panic!

 

Did I merge them right?

you could try looking at an sli efi string and try to adapt it even though there not sli, Ive done it before but not in quite a bit but osx is never very happy with it it more worth just installing one or installing one efi one by kext in the /extra folder but it's not happy with it.
