Well... this is where you AGP aperture will be in bus space.. you'd rather know what to do with it to do a driver... > :) The driver seems to work better with cant_use_aperture set to 1, so I > leave it as it is. BTW: What's the meaning of needs_scratch_page? Well, set to 1 would mean the aperture isn't accessible on the CPU space. It might seem to work better either because indeed that is the case... or simply because you put it in a wrong place (ie 0 !) There must be a chipset register somewhere that tells you where the aperture is no ? Ben. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
