THIS TOOL HAS BEEN DISCONTINUED PLEASE USE THIS: http://forums.macrumors.com/showthread.php?t=877437 I proudly present: What is ATI Flashing Tool? AFT is the first GUI-oriented GPU flashing tool for Intel Macs. What can ATI Flashing Tool do for me? Besides flashing ATI Graphic Cards, you can install / remove Natit, install Quartz Extreme / Core Image patches and check for Quartz Extreme support on your card. Screenshots: Where can I get it? The latest version is uploaded on this link: I have tested ATI Flashing Tool on 10.5.8 and 10.6.1 with no problems. But as always, I am not responsible for any bugs, faulty roms or other things that can damage your card. You can still only flash with one ATI card inside the computer. More info on this is included in the app. Known bugs: VRAM in Video Hardware Info is incorrect. Apps should close when window is closed. Alex's button is kinda crappy. The logo is a button. Where can I get ROMs? Here: http://groths.se/atiflashingtool/ROMS.zip A flashing tool is useless with no ROMs to flash with. So I included a bunch of ROMs in the zip. They are categorized and marked with notes and pictures, so there is no mistaking. Also, one of the biggest flaws with the app is that you can not take backup of your current ROM. So I included also original ROMs for the cards. If there are any ROMs not included, feel free to contribute by posting them in this thread. If you have any suggestions for the app, bug reports, grammar errors, please post them in this thread. FAQ Why do I need to remove my ATI cards? Because the app will try to flash all ATI cards it finds. Why do I need Natit? Natit enables you to boot and use 4890/4870 for display without flashing it. Why can't I just use Natit then? You can, but you won't get Apple's grey bootloader screen. You also can't boot OSX dvd's, or use the card in another computer / OS disk without first installing Natit on it. With flashing, your card can do all these things. So now we only use Natit to be able to remove ATI cards and still boot, or to run cards that not yet have a modified ROM that is working. Is there a guide for this tool? There is a guide here for the 4890: http://forums.macrumors.com/showthread.php?t=713428 It is the same for 4870 just forget about the QE_CI steps Do you accept donations? This gpu-project has already set me back 480$ due to an accident where my motherboard broke. Alot of time has gone into creating this app, and I would gladly accept any donations for my work. Just 5$ would make me very happy. Update 21/11 ATI Flashing Tool 1.2 Released NEW FEATURES: Added ROMs for new cards: 4890: HIS Powercolor without cover Powercolor with cover Sapphire New Edition Sapphire Vapor-X 4870: XFX ZDFC Sapphire 512 MB Complete with the original roms and pictures of card. The rom package is now separate from the tool. Custom Natits Since Natit is based on rom image data, it's not compatible with all cards. This was something that many problem have had problems with, after installing Natit they would just get a black screen. So I took time to rewrite Natit with rom images of ALL the roms in the Rom package. When you install Natit now, you will be able to choose your card, and then a custom Natit is automatically installed for you. Safer Flashing Flashing is now a bit safer (less chance of failure) I have not heard yet of a flash failure but I made this change anyway. Built-in Software Update Searching the forum for new versions of the tool, or more importantly, QE_CI updates, was a tedious thing and not really something I liked. So I went all the way and built in the Sparkle framework into the app. Getting the QE_CI patch has never been so easy. Updates are done automatically, or manually from the button under QE_CI or from the toolbar dropdown ATI Flashing Tool-->Check for updates... Updating will also download new custom injectors if available. I'm publishing updates with the app Feeder, which was payed for with your donations. Small changes The About section is redesigned a bit Some new icons here and there Card Table Same download link as before.
