I tried to flash som of the ROMS here, but my MAC PRO 4,1 flashed to 5,1 doesn't wants to boot. T
How did you flash your mac?! Also, I have great news for you - I flashed the same card with no problems! |

Hi Gents
Posted on the Radeon Port Mapping thread, but seems it is now slowed down. I would just like to thank you for the work you have done, Netkas, Rominator and Florian.
I used the script and EFI to modify my R9 270. Yes, I know it isn't fully supported but I edited the plist file in kexts and added the device ID 6811 and it worked OOTB using Radeon frame Buffer but of course no boot screen before flashing ROM. I flashed using your script and I now get a boot screen on the DP port and then get 1 DVI and 1 HDMI port working after boot. One DVI dead as expected due to the frame buffer used, but now in 'About This Mac' the system reads the card as HD 7950 and can read all cards in the PCI bus. So a success.
I post the stitched ROM file here for anyone who wants to use and has an R9 270. Remember only one DVI will work as it uses Hamachi FB.
Again many thanks.

Hello everybody, I need some help here.
First of all I have a friend with a Mac Pro 1.1
He bought a PowerColor R7950 PCS+ and the
Mac boots to the Operating system but it does not
show hardware accelaration and the hdmi port is not working.
I have generated the efi rom using the tools on this post
but like I said no hardware acceleration or Hdmi port.
We are using DVI port only.
Thanks in advance.

Is this version:  I have resolved the HDMI problem using a HDMI to DVI converter but still got no hardware acceleration, google chrome doesn't work correctly unless I deactivate hardware acceleration, even using launchpad feels with alot of delay. The card is correctly flashed, and it shows EFI information.   What would the solution to my problem? |

Drivers won't help him since they are 64bit and he cannot boot Lion in 64bit with 1,1/2,1. Btw, side note on the topic, With Gigabyte HD7950 V2 i could just copy/paste EFI part to GPU's ROM and everything was ok. With MSI HD7950 TF3 Mac Pro didn't want to read EFI until i ran the script.  Not a problem, just wanted to report. P.S. Hey guys, first post - finally got my confirmation email after months of trying!!!  |

Used this guide yet again to flash a Sapphire 7950. The original ASUS 7970 I use died - no screen output at all. I bought it used and suspect it was possibly used for bitcoin or OC'd gaming before I got it. The worst part was it died just after I'd sold the Mac Pro so I sourced an as-new 7950 (even smelt new!) and flashed it as a replacement for the new owner (who is now happy  ). Attached the EFI rom for anyone else who might need it. Device ID was 679A. |

Can you attach your original and edited ROM here? Gigabyte should be a breeze to flash. |
