I've been trying to flash a Toxic R9 280x but haven't had any luck. Initially I used Netkas script but it was incompatible with my installation of Python (3.x), I was unsuccessful at refactoring the script for Python3 (not a python dev unfortunately), didn't want to try downgrading/versioning between Python2&3. I somewhat successfully copied and pasted the EFI code over the cards original code; "somewhat successful" in that upon booting I am able to see the loading bar from "0% to 100% however, I've not been able to access to the startup manager/bootscreen. I've flashed a handful of cards in the past all without issue so I'm not really sure what the issue is with this one. I've also tried the (EFI'd) Toxic R9 280x ROM posted earlier in this thread, that did not work either. I've tried flashing both rom-switch positions, it seems that only one will accept a flash, is this normal?

Some background info:
I'm flashing with Freedos/DosATIFlash on a 5,1 Mac Pro
macOS boot disk is some kind of PCIe ssd from a Macbook (I forget which one exactly)
Running macOS 10.14.2
Card is a reference card (two mDP, two DVI, one HDMI)
Using an wired Apple keyboard plugged directly into the tower
27" A1316 Cinema Display connected via mDP (both mDP work during/after bootscreen)

Attached my original rom and my copy/paste-modified rom if anyone cares to take a look. Any ideas/help is appreciated.

I also have a A1407 Thunderbolt Display that I've been trying to use via a GC Alpine Ridge, and GC Titan Ridge. The Titan Ridge does not recognize the A1407 in Windows 10, the Alpine Ridge does but doesn't recognize the A1316 if it is daisy chained. I'd like to be able to access bootscreens so I can "warm boot" back into macOS and see how the cards behave (a thread on Mac Rumors indicates this method is required for macOS to recognize the card).

I tried again today, this time using the 7970efi.rom posted by Rominator here: http://forum.netkas.org/index.php/topic,5619.msg19874.html#msg19874. I tried the flashing with the file posted, worked pretty well (showed entire loading bar, and loaded at a "normal" speed) but still no boot screen access. Then I tried copy/pasting the EFI part of that file over my original rom. I can still see the entire loading bar but this time it loads very quickly (blink and you might miss the chance to hold option / command+R); still no boot screen access. The former did however show up as AMD Radeon HD 7970 in system profiler. Step in the right direction but still not great, attached the latter if anyone cares to take a look.

edit: on further examination I see that the Sapphire Toxic R9 280x isn't quite a reference card given that it has two DVIs (in addition to the two mDP and HDMI). I think now I'll start reading through the port mapping thread again and see if I can't find any hints there.
