Flashing R9 280X for boot screens/PCI System Information

[R_gui]

well here are your efi rom, you can use anyone to flash, but since I don't remember at all which video port doesn't work, could you report for us all please?

Thank you for the flash

I haven't tested them yet, but I am going to be trying to in a few minutes. The problem is that they're in .txt format... should I leave it like that or do I change it? and if I do, how do I do that?

hi coco, thank you for your reply, yeah you are right and your hatitude for this thing is right for 99% people on this world, like 99% the members on this forum, but i'm not a person easy to give up or let it go, of course i'm not a fool to do a thing without raison, specially when one said it worked and mine doesn't, i'd like to know why, and i know there is always a solution out there, since i believe my case is not the only case on this probleme, amont the millions of user on this and other mac forums, and i did not YET find the topic related, so i wonder how others solve the problem? that's raison why i'm still searching the answers. but thank you for your kind advice, but if people always easy to give up or change the directly, we will not able to take advance, and people will say well we still gain something anyway, i would say we will never get what we want in that way. i wish there are more people to discuss to help, then we will solve the problem quicker i believe. thank you for your comprehension. daniel

where have you seen someone successfully flash your card? I've looked on youtube and ebay to see if anyone is selling your card flashed, but came up with nothing. Like nobody has solved your card issue...

Well, I appreciate that yo tried to help me, but sadly, I'm having the same problem as before. I only have two outputs. Sucks too, cause my order got pushed to Tuesday. So far, not a good week. Thanks again for trying though. I really do appreciate it.

I tested it on window(running bootcamp), and I used to have 3 screens when running the OS, but now I have one - worse than the mac portion.

thank you for your reports, at least I know I'm not he only one has claimed this kind of problem here, and if you look up this sell:
https://www.ebay.fr/itm/NEW-Radeon-...h=item3b1a7a32e7:g:cdsAAOSwxKNbhMXJ:rk:2:pf:0
it's stranger that seller said can connect with 4 screens, and with boot screen, so there must be a way to solve this problem, I think, netkas script is not perfect, but it gives us an important start position, so need to find more solutions for different cards

I saw that listing too, and that's why I'm so obsessed over getting mine to work the way his does. I saw in another post a while back that the best way to work with flashing cards was to do the hexedit manually(especially when their file size is too big).I saw in another one that patching sometimes works, too. Problem is, I have not idea on how to do either of them. I've looked everywhere to try to learn, but no information anywhere. This crap sucks

your card has 5 ports, two dvi one is dead, and one hdmi dead, and two mdp worked, so basically you still have three ports on Mac Pro, it seems you've sold it before take care the problem, my advice: tell your client the truth, either he buy this series model with two dvi, one is always dead, and hdmi too, so you take the responsabilité, he will understand, tell him give him this one fresh tested, or refund him, then sell it to another one, it will save your time, and your reputation

don't say that, there always problems in life, try to think this way, the sellers on ebay, they've been studied from 2008, the beginning of flashing cards, so take your time, don't blame anyone, don't give up...

or you can buy it first, then flash the right rom, then sell them too, little investment, but you don't loose your money

I don't sell gpu's and I'm trying to fix this because my previous cardx(quadro 4000 (2x)) wasn't working with heigh sierra and made it impossible to install mojave. So, I found this sapphire card and everything seemed to be working out out- at least somewhat. Again, I am doing this for me because I need to see the outputs on my screens lol. Not so I can turn around and sell my only working gpu. If I did that, I'd be pretty stupid since I'd have no way of seeing anything from my workstation. So, I have no "clients" to apologize to besides myself since I've wasted countless hours trying to get my 3 screens to work. But again, thank you for trying and taking a chance on me. I know you didn't have to, so thank you.

 

[parisinvest]

I've just found my old sapphire 280 (not 280x) dual card, and it has efi rom works well on dvi hdmi and dp ports on my mp, it's been lying on my desk for months, I don't have any idea where was the rom come from, but definitely not the msi version, but since I don't have a 280 bundle, so could anyone repost a 280 bundle please? or is there a way to pick the efi file from its rom? many thanks

Stop it here, this is not a fault of netkas' script because it only adds the mac EFI to the card and aligns the rom's checksum. Nothing more. It changes no port allocations and so on. Dont blame netkas' script for that.

with all my respect, i did not say this script is not good, nor blame on it, just to discuss why difference resulte on the same model card? and why 280x works perfectly, and 7970 has hdmi dead, and some other marque does de reverse: 7970 perfect but 280x hdmi dead? and why no people talk about it? i've flashed about 50 cards, and i think i can have a words on this problem.

Pretty simple answer:

Despite the fact that the 79x0 and the R9-28xx have the same chip, there are minor differences on the cards, such as the SPI NAND make, model and size, different memory configurations (sk-hynix, micron, samsung, etc.) and so on.

For example. if you have exactly the same looking 7970 and R9-280x, which also have exactly the same rom, you will get the same flashing experience, since there was no change of port asssignment.

But if only one of the two cards is different in some way (even if one of them has a different bios), then you will get different resuslts, as the one has all ports working, the oher not, becaus THEY DONT SHARE THE SAME PORT MAPPING.

This is not to blame you.

But i want you to understand that you CANNOT change anything only by flashing different roms...
You need to manually edit the rom, but if you can do that you were a gpu rom designer and wouldnt need to ask those questions.

please don't get me wrong, i am not going to assault you, but i fear that nobody cas answer the questions but the developers of the cards bios, which have assigned the port layout to the bios (which no script ever is touching here).

hi coco thank you for your messages, i appreciate your explications, i understand what you said, and yes there is something we should leave it as it is, but not before i know it, i did not pay attention on which model which port works or not, because one dvi with efi is enough for me, but with discovering the problems, i've retested half of my card i've flashed, even asked some my former clients whom i know well, i've a list for members here to verify before member buy new card for them, so we will know their cards' reaction after script before buying them, i will post it soon later, i think this is the first useful part after this discussion, but if we let it be from the beginning, we will not get this, here, now. and i believe we will discover more useful things for members, everything has two parts, good side and bad side, i'm a person who chase for truth, i believe that matters for someone too. this is a big family and lot of members and messages here, not everyone could have time to solve everything, so we need to teach each other to have more expert here to help others, this is the only way to make long life of forum, i think. thank you again and see you soon.
btw are you a girl?

? no i have a dingdong .. dont understand why thats important...

non that's only important for yourself, it's just the way you speak like a girl, because you think more about others‘ feeling, and speak very kindly and polite, if you are that's so cooooool! but it's nothing please forget it

 

[cococheaf]

Courtesy, respect and decency are virtues that one likes to forget in this day and age.

Nevertheless, we should revert back to the original topic in this thread.
I'm out for now as i have nothing more to say.

Hi,

This is my first post on here so please be gentle with me!

Okay, I've got hold of a MSI R9 280x off of eBay and flashed it using the .rom file Mr Zarniwoop posted at the very top of this thread; the flashing went fine and when I rebooted my Mac Pro, the full boot sequence displayed correctly on screen.. result!

However, on checking 'About This Mac', I see AMD Radeon R9 280X 1182796800 MB - obviously the memory bit (which should be 3gb) is incorrect. Can anyone help in advising me how to get this corrected? I have included my default PC .rom file.

Thank you.

simply you are using someone's efi rom, not your card's, you need to use your own card's rom to make efi rom to flash, even you have the same subvendor and same model card, or your will meet eh problem like you mentioned, the netkas script will do all correctly, please do cherche in forum to download it, just dont forget to install jave and python at the same time, then do the flash again, the problem will be no more

your rom is wrong, use the laste version to get the rom file, and don't make zip, just add ".txt", and send it again, before you send it, you may check the size of your rom is 131 k, this is the right size for flash, or it's wrong like the one you put it here, if you continue making 262 k rom, then ask someone to grab the rom for you.

I don't know how people did to get this double size rom, I've never met, could you confirm your computer configuration please? thank you

There are plenty of stock 256k ROM (anyway, we usually call that 256k, not 262k. The other one is 128k, not really 131k).

For any non 128k ROM, the Netkas script won't work. You better stop asking him to do that (or try to do that for him).

Parisinvert try to help you, but he has no idea about this 256k ROM thing. You did nothing wrong on the ROM dump. But just simply bought a card that cannot use the normal way to flash it

However, you can manually cut the 64k Mac EFI out from any 7xxx Mac EFI ROM, and replace the UEFI GOP part inside your original ROM image. I just check your ROM, the UEFI GOP start at address 10000. Replace that by the Mac EFI UGA. Then, you should have a 256k Mac EFI UGA ROM for your own card. Remember, the ROM size still 256k at the end. If the file sized changed, that means you did something wrong in the hex editor.

In general, this is not a good idea to do, especially if you are very very beginner for flashing card. However, as long as your card has dual ROM design, this is safe to do so. It's really nothing more than cut and paste in a hex editor. If you can't do that, you better forget about flashing.

Since your card should has a ROM switch. You may leave it as your current config

Rom 1 - stock healthy ROM, for daily use.

Rom 2, the "bad" flashed ROM, only use its boot screen ability when in emergency.

Unless you really need the boot screen everyday. There is no need to "fix" the card if you don't quite know how to do it properly.

hi you can follow the netkas script procedure, it's very popular and you can find the detail here in macrumors and netkas forum too, http://forum.netkas.org/index.php/topic,692.0.html , just make sure you install java developper and python before you start the flash thing, btw this card will only have one dvi worked on Mac Pro after flash, so you may want to change the card before do anything, you can choose better one from here: https://forums.macrumors.com/thread...-script-effets-on-differents-amd-gpu.2157433/

Did anyone managed to get 4K @ 60Hz on HDMI? I'm stuck at 1080p !!!

 

[Alaska_guy]

Have you been able to get 4k or 1440p with that same hdmi cable before? Not all hdmi cables are equal. Your monitor and cable need to be hdmi 1.4. I have an older cable and I was having the same issue. Swapped cables and correct resolution.
