The official driver for all dual-core and quad-core Power Mac G5 models for the ATI X1900 GPU. Tiger requires this driver for full utilization of ATI graphics cards. Although not required as much on Leopard, installing this driver will provide the ATI Displays program, which allows you to configure the GPU, so the installation is recommended for both Tiger and Leopard.

Tiger needs to be version 10.4.7 or later.

The driver is archived here to assist those who somehow are prevented from downloading it from ATI / AMD directly, from

The driver also works with a flashed ATI X1950 XT (but not XTX), both 256MB and 512MB versions, although only 256MB is utilizable.

For Client Tiger and Server Tiger PPC versions, at least in the case of the flashed X1950 XT, you can install the drivers with the GPU inserted beforehand, but with Mac OS X Server Tiger Universal, the card has to be disconnected before installing the drivers, simply because otherwise your system will not boot without the drivers you are attempting to install. After installing the driver, you can connect the GPU back and boot with it normally.

The flashed X1950 XT is incorrectly reported to have only 128MB of VRAM in Client Tiger and Server Tiger PPC, but all 3 versions of Tiger fully and correctly use all 256MB of VRAM from this card without any issues, as proven in this thread.
