So here's the deal ... I challenge all of you Mac Gurus out there to solve the OSX - PCi Video problem. (Full disclosure: I have a Radeon that I spent good money for and now it panics at OSX bootup in my 7300 G3). There's got to be a way to make these cards work. One thought I had: it seems like people who have machines with onboard video are having the biggest problem. Is there a way, using software, to temporarily disable the onboard video so OSX thinks the PCI card is the only one there?

Anyway, get working everyone. Weve got to solve this, or be satisfied with unaccelerated video under OSX.

I have a challenge to add to that challenge!

Give us Voodoo support - at least from the V3 to the V5!

So long and thanks for all the fish!

Radeon works fine under OSX in Yose, Sawtooth, and bG3.

I'm impressed that you can get the release version to run at all on vintage hardware.

Yes, I know. I'm trying to force something that shouldnt be forced. But it's not just me. Sonnet just released its installer for OSX. For $30, anyone with a Sonnet G3 or G4 card can install OSX on any vintage PCI machine. It runs fine, really fast with the backside cache. The video card is the only problem.

Free Legacy machine OS X support is available at: http://eshop.macsales.com/OSXCenter/

While the video card problem is the same with the is installer as it is with the $30 Sonnet software, Ryan is working to correct that. We will be having him work with a multitude of different hardware products to bring them into compatibility with OS X. http://macgurus.com/infopop/emoticons/icon_smile.gif

Do you think you can have Ryan do something so that there won't be kernel panics under OSX with 3dfx Voodoo cards in? Lots of people still have these in their legacy Powermacs, as I still really like my Voodoo 5 card.

Hi all,

I've managed to get a powermac 8600 boot linux 2.4 ('s been long since I
didn't try).
The trick is that in 2.4 kernel, linux tries to open the first frame
buffer, and on machines of the 8x00 class this mean opening the sixty
convoluer, a frame buffer that allows the use of the video output (Y/C
and composite).
Unfortunately, linux has not a driver for it so the opening always
fails, and the machine goes back to OF with a DEFAULT CATCH something.

In 2.2, the behaviour was different in that it tried to open every
framebuffer, or every frame buffer up to succes, I don't know, so this
machine was used to work well.
-------------------------------------------

Perhaps OSX has a similar issue.
