MP 1,1-5,1 Can’t flash HD 7970

[docone_DK]

Hi
I have a Saphire HD7970 that I had flashed and it was working fine in my MacPro 2009 updated 5.1 running Mojave but it couldn’t startup with startdisk choice (+ ALT) so it was thinking that it wasn’t flashed correct.
After a lot trying I’m almost tearing my hair off.
The card has a 1 -2 dip switch with original bios in position 1 and flushable i 2.
I have lost my original rom so I can only start i position 1. When I do that and save the rom, change to book 2 and load the rom in I get subsystem mismatch.
I have tried downloading rom from techpowerup but none of them works. Som can’t be programmed and others can be programmed but the computer get i a startup cycle.
What can I do, I only would like to have it mac’ed with bootscreen.

Always make the Mac EFI ROM from your original ROM, don't download it.

If position 2 still with factory ROM, you can boot with position 2.

Then create the Mac EFI ROM, press the switch, flash the modded ROM to position 1.

I posted the step by step guide about how to use the Netkas script to create the Mac EFI ROM

Help Overclocking 12 core Mac Pro

I prefer to use VBE7 to adjust the OC voltage setting, save it to a new ROM image file (e.g. file name 7950OC.rom). Then enable the EFI part again by the fixrom script rather than perform the hex edit. To enable the EFI again. 1) Boot into OSX 2) Go to system report and get the device ID...

I have saved the ROM from the working BIOS (position 1) if I then do the NETKAS steps and try to program the card in BIOS (position2) I get a SubSystemID missmatch.

 

[Macschrauber]

You need your card's id and not from the example.

And somewhere in the instructions is an id typo, something reversed like 679 to 697, but dont matter if you understand the steps.

Today I retried the whole process, flashed it. But still nothing. I attach the original and patched ROM. Anyone can give me a help?

I have the original file and created the netkas file, flashed, but seems not to be working.

Thank you

I think I did everything correctly.
Can you please check it? Or try to create a correct one for me?

Would be much appreciated.

I checked your ROM image, you didn't do that correctly, please follow my exact steps to do that. Any modification to the process may fail to create the required Mac EFI UGA ROM.

Sorry, no.

I did that before, and end up the member use that ROM to sell cards on eBay. Since then I will only post the "how to" but won't do that for others.

That's a fair subject and won't even debate it.
Can you tell me what I did wrong, or where is the mistake?

Thank you for your help

It's hard to know which step you did wrong. All I can see is that your EFI ROM is practically identical to the original ROM. Which means you did something wrong in the command, and the script fail to replace the 2nd half of the ROM by the Mac EFI UGA.

That's why I suggest you follow the exact steps in my post (with all the details, e.g. use USB thumb drive with no space in any drive's / folder's name)

Of course you will need to edit the path in Terminal to suit where the Netkas script is located - I suggest that the script folder be on your desktop.

I guess not. I tried the file that came out with Java, but still no...
Somehow I think the "damn" GPU refuses to get flashed. I mean, yes it says it got flashed, but when restart Winflash and he check it, it´s exacty the same as before.

I leave attached the efi rom that came out.

1) Your USB drive named "UNTITLED 1", which can be a problem, NO SPACE in the name

2) Java... it seems you fixed this already.

No, it´s named UNTITLED only, exactly as you say to do on your post on the other thread.

Do I need to unlock something for the flashing process to succeed?

Is there any other drive named UNTITLED? You capture shows your USB named UNTITLED 1. Therefore, the script can't locate the reuqired files.

If that name doesn't work, try another name. e.g. ABCDEFG

I'm having the same issue. were you able to figure this out?

Update: I was able to create the rom file after booting from High Sierra instead of Catalina. My sapphire 7950 was flashed and everything works fine except the HDMI port. Any suggestions? Thank you
