Windows 7 is Microsoft's next major PC operating system. Early non-retail versions of this OS may have already made it to certain sections of the industry, and this calls for hardware support. AMD is ready with its ATI Catalyst driver suite for Windows 7. The driver itself is titled ATI Catalyst Windows 7 Preview Driver Package. As the name suggests, it is at an experimental/early stage, much like the OS itself. Use of it is not covered by any warranty. It provides support for ATI Radeon HD 2000 series, HD 3000 series, HD 4000 series, derived mobile GPUs, and AMD 7 series chipsets with integrated graphics. The 32-bit version of the driver can be downloaded from here, and the 64-bit version here.
