What sort of mods > will it take to make that work, anyway? There is work now in X to get this working, it requires a layer of PCI abstraction which is pretty raw at the moment. Hopefully in a few months something solid should come out. However, since we're discussing Rage128 cards in Mac's here, it can be said that the vga IO that is being done is totally unnecessary, as the Rage128 does not require a vga mode to be saved or restored on Macs. So totally disabling the vga IO if you are just using those 2 cards on your machine can be a valid solution (for your situation, obviously not an X solution). > I've discovered that putting both cards in bus 0 (64-bit, 33 MHz bus) gets > both the cards going, though - and well, that works for me... Yes, unfortunately though people on AGP G4's tend to use an AGP and a PCI card. I suppose they could do what you are doing and use the bottom 2 (or however it works on G4s) PCI cards if they have 2 PCI boards. ani ** Sent via the linuxppc-dev mail list.
