lot of .mac sites ... strange ;) ). 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
