MacPro 2,1 Needs Help with 5770 EFI Flash

[kiresp]

Hi Guys,

I have El Capitan working almost perfectly on a MacPro 2,1 except my Video Card.
I can boot with the 7300 and it's slow as crap, I move the DVI cable to the ASUS 5770 in bottom slot and it works fine from there.

The card is recognised as ATI 5000 series, I can't get EFI boot selector, and no login screen if I boot with DVI connected to 5770. I need to boot with monitor attached to 7300, then move it to the 5770. I found a netkas forum post on flashing this card with EFI+BIOS using some hacking around to make your own image and flash back to the card.

I can't find the EFI file referenced to download anywhere;

5770_vervet_netkas.efi

Anyone done this before, where can I get the EFI ?
I've tried several times to register to netkas forums without any luck.

Ideally I'd get this 5770 flashed, then chuck out the 7300 so I can move onto more interesting things like the CPU upgrade and bluetooth/wifi module.

Thanks for your help.

I've made a guide some months ago, about "saving your 5770 after a bad flash".
In the text, before the last picture I've included a link to my own ROM file for the genuine Apple ATI 5770.
You can read it here: https://forums.macrumors.com/threads/how-to-save-your-ati-5770-gpu-after-a-bad-bios-flash.1894948/

I hope this helps.

Did you ever find that file? I'm having the same issue but with a sapphire card.
