After a long search, I finally managed to buy my first PowerMac G5 7.2, which still works great after all these years!

MacOS does run great, but to get the Morphos experience I need to use an ATI graphics card. I have one old Radeon 9200 SE card from Gigabyte but I have no idea if it will work on a Mac and if I need the corresponding ROM file, since the frequencies of this card are not quite standard for the 9200 series


Is there any way to make this card compatible with Mac and what do I need to do for that?

If you want see output from firmware and use OSX, you need Retail/OEM/Flashed card.
Here is compatibility chart,

I.e. PC card needs to be flashed with reduced ROM.
Here is flash howto and download section.
