OS downgrade...
I have a PC bios Radeon 9550 with 128MB VRAM. I was wondering if I could flash this with a downgrade Mac-compatible ROM to go in my newly purchased Dual-2.5GHz G5 Powermac 7,3.
I was thinking of going down to a 9500 non-pro or 9500 Pro. Maybe even up to the 9650 ROM from here -> http://themacelite.wikidot.com/wikidownloads2
If anyone could help out, I'd appreciate it. The MacElite forum is down until further notice
Many thanks.
PS. I just discovered it comes with the Radeon 9600, so this may all be academic really...

I'm thinking of downgrading the OS from 9.1 on my performa 6200 to OS 8.1........I'm just hoping someone can give me a small list of pros and Cons of each OS... Also, would mozilla run on 8.1? IE 5.1? Is OS 8.1 A LOT faster than 9.1? I got a 20gb HD 5400rpm, 48mb RAM, and it has a 75mhz 603 processor....Well thanks a bunch!

The 9550 uses a considerably slower core over a 9600(pro) - 250Mhz over 400Mhz - but some cards had the ability to be software/hardware modified to beome a 9600Pro in the PC world. I'd google the exact card to see if it has the ability to be BIOS modified to a 9600. Also remember that a 9600XT is a different card and you can't flash to this. Looking at the available ROMs, there isn't much of a choice so I suspect you might have difficulty.

AFAIK, the only drawback of running 8.1 as compared to 9.1 (or 8.6 for that matter) is the inability to use CarbonLib 1.6 and run the apps that supposedly require OS 9. Many of those apps really only require CarbonLib 1.4 or later, but 8.6 and 9.x are the only OS versions that support that version of CarbonLib (which, incidentally, is pretty close to the same Carbon supported in OS X). Curiously, you can install CarbonLib 1.0.4 on OS 8.1 and achieve some compatibility that way....
OpenTransport is much more stable and faster in OS 9 than in OS 8, but I doubt you'll be spending much time doing serious network transfers on your 6200. Similarly, multitasking and multithreading are improved on OS 9, but the 6200 is really the limiting factor here and not the OS.
So, in short, you probably won't notice much difference between the two OS versions aside from speed. And that will be a largely subjective measure. Give 8.1 a try and tell us what you think! Do you think it is faster on the 6200?
Peace,
Drew
