Flashing R9 280X for boot screens/PCI System Information

[MacVidCards]

If there are 0000's at end of PC BIOS part, replace with FFFF's.

Rom should be 131,072 long, if it is 262,144 you can check last 131,072 and it should be blank, just delete it.

Again I am not home, so will try as soon as I get home.
Thanks again, lets hope it works .

If that doesn't work, my be you have to fill the FFFF by yourself (as MVC pointed out). I've check your original ROM, the PC BIOS part is ended with 0000.

Yeah I saw that too. Thats giving me new hope.
I am trying your rom first. And if thats not working I try the FFFF to 0000 change in Hex.
Thanks again.

Edit:
At the end there are a few rows with 00000000.
Than one time 0000001C, and after that all 000000.
Do I have to change only after 0000001C to FFFFFFFF?
Or the 00000000 before 0000001C as well?

 

[h9826790]

TBO, I don't know, but I will follow the exact suggestion as MVC said.

IF the PC BIOS ended with 0000.

THEN replace that with FFFF.

So if that's end with 1C, I won't touch the PC BIOS part.

I used the one you made (I made one with the FFFFF's as well to try, but didn't try that one yet).
The one you made works kinda. It boots with bootscreen, seems to run fine as well.
BUT:
I don't hear the starting boing sound anymore???? weird.
Next to that, if my 4K display is plugged in it does not boot at all. If I take it out at boot, and plug it in after boot, everything is fine. Not a handy way to work with though.
For now I can live with this though.
I just boot with the original BIOS normally, and whenever I need a bootscreen for some reason, I switch the bios switch and take out the plug of my 4K display.
A bit of a workaround but oh well.

 

[h9826790]

AFAIK, this EFI only support boot with non 4K display. Even though I can show the boot screen on my 4K TV, but that's just luck. Also, it seems boot with 4K 30Hz is OK, but 4K 60Hz is not.

About the start up sound. Reset PRAM will do the tricks. It may be caused by as simple as you mute the machine.

Thats not very handy. I have to unplug the screen to be able to boot my computer.
Well at least I can work around it. Next reboot I will do the PRAM reset and see if the boing comes back.

 

[h9826790]

If there are some switches on your monitor which allow you quick switch to non-4K resolution / 4K 30Hz. You may set that before boot, and then set it back to 4K 60Hz after boot. It's a bit more complicated than just press the power button. However, IMO, still better than keep playing around the cables. If this work, then you can have both boot screen and 4K 60Hz.

Otherwise, simply don't switch on the monitor until booting complete is another simple work around.

 

[MacVidCards]

If I test 4 @ Tahiti cards in a row on Dell 5K (to cards it is SST 4K 60Hz) some will boot loop, some will have black boot screen, gong, and get to desktop. Newer R9 280X more likely to boot properly, seems almost random. Some choke when MDP connected to 4K, some don't.

Btw, gui version of flahser - atiwinflash has issues with 256kb roms, use command line atiflash if you gonna flash/read 256kb rom.

Oh, I used Atiwinflash. It did work though. Although not booting with my 4K screen attached. But I don't think that is related to that issue right?

 

[rawweb]

I've spent the last hour combing through post-by-post looking for one.

UPDATE: ok, found one. Appreciate you egging me on to keep looking.

The ROM I made from your work is attached in case it helps others. Thank you so much!

The card I used:

MSI RADEON R9 280X GAMING 3G (TWIN FROZR IV, OC EDITION)
part number 912-V277-067 (on box)
EAN 4 719072 314026 (sticker on card)
UPC-A 8 24142 01599 5 (sticker on card)

Information on the EBC firmware attached here:

Subsystem ID: 0x2775
Device ID: 0x6798
PC BIOS (stock as shipped): 113-MSITV277MS.350 TAHITI B0 XTL C38650 GDDR5 3GB, BIOS Version 015.041.000.000.003435, ROM Revision 113-C3865001-TU5
Mac EBC EFI: (replaced stock UEFI): ATY,Hamachi, ROM Revision 113-E2080C-101, EFI Driver Version 01.00.624

Just wanted to say thanks a million for posting the rom and everyone's hard work that contributed to making this available. I picked up an MSI 280x on Craigslist (exact same card as original poster) for a steal and had the card flashed and running in my 5,1 in minutes. Absolutely painless.

Also, removal of R17 is a breeze...Save for a perfectly timed distraction that caused the accidental removal of R18. Wah, wah, wah was a sound effect heard for miles...Added about a half hour of unnecessary and curse word filled moments under a solder gun. No worries though, all is right with the world as if nothing happened.

Looks like most of the recommended cards are now very hard to find.

I am thinking of picking up a Sapphire R9 280x Vapor-x card:
http://www.amazon.com/Sapphire-VAPO...0784&sr=1-1&keywords=sapphire+r9+280x+vapor-x


Any thoughts on it?

I know MVC mentioned earlier in the thread issues with cards with single DP connectors, but there was at least one person in this thread mentioned having success with this card.

Just looking for some secondary opinions as I can scoop up one of these cards locally for a good bit less than what Amazon is asking for it.

IMO, even follow the exact instruction, sometimes thing still go wrong. If you intent to choose a card with non standard port / non reference design etc. You are increasing the chance to fail.

If the boot screen is not a must for you, then you can still go for this card. As long as you keep one ROM with the stock BIOS. You should be bullet proof. The card should work, just no boot screen.

However, if you really need the boot screen (TBO, when things go wrong, the ability to show the boot screen will make life much much easier). I personally will play safe and not to pick this card (unless it's much much cheaper than normal to a level that it's worth to take the risk).

 

[Fl0r!an]

I have a Sapphire 280 (non-X) with the same layout. Flashing worked fine on this card, lost one DVI, no problems beside that.
The HDMI port will be mapped as 2nd DisplayPort working in legacy mode. Don't know if this has any disadvantages though.

I'd suggest getting a reference card though, it's safer and you might have a different port layout on your card than I have. My card is working in a hackintosh so it won't matter, just flashed it to see if it works.

 

[mathemabeat]

Thanks for the info guys.

What do you think of the Club 3D R9 280x card?

http://www.amazon.com/Club-3D-Royal...pebp=1440640775890&perid=11ZCCQEYE621ED8FFE5A


It looks like a reference connector layout. Though I am not sure if it has a dual bios on it or not.


I have scoured the net for the MSI and Gigabyte suggested cards and there is very little supply of them new. And those that do have them are charging a premium for them.

 

[mathemabeat]

Well, I sourced a used Gigabyte Rev 2 R9 280x card for a fantastic price. Super stoked for it to arrive.


4k video @ 60Hz. Yay or Nay?

I want to give a huge thanks to everyone who has contributed to this thread. After reading through everything on here and netkas I was able to edit the rom from a Powercolor 280X and get it running in my 4,1 (flashed to 5,1) with boot screens and to say "R9 280X" in the system information. This is the card I have. I also did the R17 removal.

When the Mac boots, I see the Apple logo, followed by a gray screen with the progress bar. At about the 1/3 point on the progress bar, the screen will change to black and the progress bar moves to the lower left hand corner of the screen. Does this happen with other cards? Any ideas what to fix in my rom?

I swapped my 5770 back in, and it booted normally with a gray screen and centered progress bar.

Then I went back to the 280X and it did the same black screen and progress bar in the lower left corner. Other than that, this is a huge improvement over the 5770.

 

[MacVidCards]

I have seen this on Nvidia cards.

Don't know what it is, but it isn't "broken", so don't worry about it.

I've seen something similar when coming from my DOS partition after flashing on certain ports. Vanished after some reboots, so I guess it was a bad PRAM setting...

I get this too with my Saphire (MVC Flashed) 7970 about 2 out of 10 times. It's never caused a problem though.

 

[garyglitta]

Has anyone had any success with the Powercolor AXR9 280X 3GBD5-T2DHE/OC card?
I have been told that a R9 280X is the best upgrade for my Mac Pro 1,1 and this particular card is very well priced where I live. I just don't think I could bear to buy yet another card that has issues with my mac.

I've tried to ask the same question on netkas, but I am having issues registering. I think their spam filter has disallowed my username and the site won't allow me to register under a different name using this computer. sigh.

what is the power requirements for that? I am looking at the xfx double d r9 280a, but i can't seem to find if i will need an additional power supply and what the damn thing consumes for power.

Hi, i can make work fine the XFX 280X in my Mac Pro 5.1. I flash the gpu with 7950 Mac edition rom. Works fine with boot screen, and i tray Final Cut Pro X with the test bruceX and i have 43 seconds. Enjoy.

Disculpa, pero puedo entender que te funciono esa XFX?

Mi entendimiento es que esas tarjetas no funcionan bien para esta modificacion.

For english speaker:

"sorry, but if I understand that correctly, were you able to use a XFX card?
My understanding is that those cards dont accept this mod"
