OSX supported video Cards


I'm all confused as to what systems can install osX. I have a G3 266 desktop and have been thinking about upgrading it with a G4 so that I can run OSX at a reasonable speed. However, I have a ATI Rage 128 XL video card that I use in a PCI slot as an upgrade to the standard video on the said above desktop. I read somewhere that OSX will only install and run properly on machines that use the Apple factory installed ATI cards. I realize that I won't be able to use the video i/o options this card provides regardless, but I would like to keep the acceleration (low by todays standards) in OSX. Any idea as to whether OSX will install on this setup?

Thanks in advance,

OS X installed fine and works well with my ATI Rage ORION card. I'm on a beige G3 266. When OS X is booting, it boots only on the internal sucky video, but the installer and such will eventually come up on the ati card. Ati has a good relation with Apple, so most ati stuff works fine.

Hope it works for you.
