7xxx rom creating test.

[3xploit_Infinit3]

Hi Netkas , I'm trying to get 7970 Efi.rom for my XFX 7970 and 7990 as well but what I did not understand is that the dump I have to do has to be on PC right ?
Is that something you do with ATIWinflash? I'm sorry but I just started no long ago to look deeper into it , because I was really frustrated after I purchased my card and me not being able to find something , I guess that now maybe I'm on something ...Maybe I really need help to understand what I have to do .

Thanks

Hi netkas, Rominator

Thanks for you magic bundly but I'm having an issue using it.

I've got ASUS R9 280X DC2T-3GD5 3GB card, here is what atiflash tells me about it:

When I dump using atiflash without options it produces a file of 256KB size, but I can also get a 128KB file if I specify that size.

I tried both files with your bundle, but whichever rom file I give it there is always a problem with fixrom.py at the end. Here is the output:

the rom is ready at bios3.rom.efi.rom

When I tried to flash the resulting image I was unable to boot in OS X, and boot screen didn't appear. Luckily, windows was still booting so I could flash the original rom back.

Could you please give me some insight on how can I fix the fixrom.py (as I saw several users asking about the same issue but no answers were posted)? I guess the problems I had with the modified rom were because of a wrong checksum.

Hi,

I'm running a 2,1 batched 1,1 MP running the final release of Yosemite.
The stock XFX HD 7950 runs fine and is named in the system as AMD Radeon HD 7xxx 3072 MB.
I would like to have the bootscreen on my 2,1, but I just read the whole thread and as Rominator pointed out on the first pages that the flashing is for MP 3,1 and later.
That being said, I'm just curious what the benefit would be of running a flashed HD 7950 on a 2,1 MP.
I used the Netkas bundle, and I succesfully created an refi version of the ROM (at least, I think so). But after flashing the altered ROM, no difference. Ofcourse no bootscreen due to the 32Bits EFI limitation, but the card is still pictured as an AMD Radeon HD 7xxx 3072 MB videocard. So I'm a little confused right now.
I attached the original and the altered ROM.
I'm to scared to use the Rominator HD7950 ROM, cause I recently bricked a HD5770 using another ROM than my own.
My videocard is a XFX R7950 Double Dispensation PCI-e 3.0 3Gb DDDR5 p/n FX-795A-TDFC.

I am sorry you are having so much trouble understanding things.

You have gotten everything backwards.

Since the Tiamo boot loader came out, flashing 7950/70 for 1,1/2,1 is now a GREAT idea.

Gives boot screens, etc.

Looks like you made a rom but didn't flash it yet.

I will give you a hint . Device ID of the 7950 is 679a . Edit your command and reflash with the new ROM.

Haha, didn't see the 79 and 97 swap so thought I didn't have to edit the command line. Will try it again. I did flash it, as a matter of fact even twice, but with no results and went back to stock rom to be safe.

And to Rominator. Glad to hear that it is a great idea to flash it. I read a lot of pages, for the 5770 too, so I became a bit confused indeed. Sorry.
But if it works, do I have the bootscreen directly throught the DVI-port or do I have te use a DVI-VGA adapter on the lower port, like with the 5770?

Update:
Like pointed out by dyttioaoa? I didn't notice the 679a vs 697a. So edited the command and flashed the new EFI-rom.... and....

IF I COULD I WOULD KISS YOU GUYS!!!

Works like a charm. Bootscreen available on DVI and MDP. System recognized the videocard as an HD7950. More resolutions to choose from. Even 4K. I'm a happy man.
Although I did lose my HMDI port, the DVI and MDP ports are working, so 4 out of 5 ports isn't bad.

So succesful flash of XFX R7950 DD partnumber FX-795A-TDFC (no working HDMI!)
Link to EFI-rom

Thanx!

Appears that upper DVI isn't working too, so were down to 3 out of 5.
And I opened a topic in MR cause a PRAM reset causes the Mac to hang on a reboot. Might be the graphics or the SFOTT boot loader.
Will be continued...

[Mr. Zarniwoop]

Since the Tiamo boot loader came out, flashing 7950/70 for 1,1/2,1 is now a GREAT idea.

Does flashing an R9 280X work equally well with your MAC7950.ROM file?

In reading the forums, it sounds that way, and also sounds like using a 2.0 card with DVI and dual MDP seems to be the safest approach?

Do I have all that right?

[maclemming]

I think I may be going nuts... hope someone can spot where I'm going wrong!

Okay, I have a Mac Pro and decided to purchase a 2GB XFX HD7870 Core Edition graphics card, with the intention of flashing the rom to make it fully compatible my mac.

Out of the box I can use both mini display ports (I have two apple screens) but as reported here, I don't get to see the boot process.

I have flashed (I think?), using the instructions here but I'm still not getting the boot sequence and the card is showing as 'AMD Radeon HD 7xxx 2048 MB' in the system profiler.

Here's what I have done:

1) Dumped my current rom using Darwin Dumper.
2) Used command './makerom.sh --efifile=7950mac.efi --romfile=efiromheader.rom --originalrom=7870.rom --devid=697e' to make new rom.
3) Rebooted system into bootcamp (Windows 7) and via command line used 'atiwinflash -f -p 0 7870.rom'. (I used the new rom after renaming it 7870.rom).

All processes seem to go through fine but my card still says the same.


Any one willing to throw me a suggestion?

Thanks.

Without further ado: Sell the 7870, buy a reference 7950, edit the command (ID of 7950 is 679a) and reflash .

[xelanaiznac]

hi guys. so no solution for the hdmi for a reference 7950 (1dvi, 1 hdmi e 2 mini display port)?

[Rominator]

True reference card will have perfect HDMI

Not sure what you mean

[xelanaiznac]

Not sure what you mean

sorry for my bad english.
i mean, i flashed with your rom a sapphire 7950 with this layout: 1 dvi, 1 hdmi and 2 mini display port. (same as 7950 mac edition)
hdmi is not working. is there any solution for this "bug"?

[VovS]

Regarding the HDMI...

As it was discussed earlier — HD7950 seems to have two reference designs:
http://www.bit-tech.net/hardware/graphics/2012/01/31/amd-radeon-hd-7950-3gb-review/2

Should I be looking for a card which has the same design as Mac Edition?
Or the card with the second design will have working HDMI as well?

Thank you in advance!
