RomCreator for ATI/AMD cards.


Just select where you want to get bios rom from – card or file

then press – select bios rom to confirm selection or select bios rom file

then select efi rom and press “create rom” to save your created rom

if some errors occurs, you will see it in error log.

Link to app –

efi roms you can get here – efi roms

Dumping is only possible if you use native drivers, dont use it with aty_init, risking to get bad rom.

Also, don’t use with card which has MCuC section, like radeons 4xxx

Flashing does nothing for hackint0sh, its for MacPro only.

    Where do I get EFI Rom for 5450? The link brings to posts that discuss Rom for higher cards. I can’t link(s) to ROM downloads.
    Please help anyone?

    To make this run in 10.6.8, right click the ROM Creator app and select “show package contents”.

    If you have the Developer tools installed, open the “info.plist” file.

    Change the Mac OS build number to “10K540” (without the quotes).
    Change the field entry marked “macosx10.7” to “macosx10.6.8”
    Change the Minimum OS to “10.6.8”

    Save the file, and launch the app. It now runs in 10.6.8 just fine.

    hello, is it okay with Lion ?

    Yes, it’s fine with Lion. It was developed with XCode 4 targeted at the Lion GM build as the minimum OS. It works fine in 10.6.8 with a simple .plist key field modification also.

    Radeon HD5450 has been running since 10.6.8. Add device id to ATI5000.kext which is 68f91002 and you are good to go

    Is it possible to save the original rom to disk?

    hi! I want to ask if its possible to use that to update an iMac 27” Late 2009 from Ati 4850 to Ati 6970m… buy separate part, extract EFI from an original iMac with 6790M and then with a pc machine, install that EFI and then place the video card into my iMac.

    can I do that?

    Since I don’t want to get a bad rom, is it enough to just remove the ATY_init.kext (and maybe rebuild the kextcache…)?
