What I am wanting to know is, does anyone know anything about writing a video driver in Darwin / OS X or writing a 3DFX driver in general, as I am not above getting my hands dirty and attempting one ( how bad can it be ? ). It is likely that the card has an EEPROM with an OS 9 ndrv driver on it. OS X supports these (and only these) OS 9 drivers, with some caveats (search IOKitFundamentals for 'ndrv'). So its likely that the card works at all because of this ndrv. Unless there really is a OS X native IOFramebuffer for 3dfx cards, but I don't think so. no, I don't either I guess the reason Darwin doesn't support them is because it doesn't have to be backward compatible with OS 9 ( ?? ) Anyway, writing an IOFramebuffer is what you'd need to do. But without docs on the 3dfx hardware, it'd be near impossible I dare say. you're probably right down the Apple store for me then ; p _______________________________________________ darwin-kernel mailing list | darwin-kernel@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.
