Hate to say it but there is not, and will not ever be Windows 7 support for that card. Reason being,
Windows 7 - Official system requirements | Hardware 2.0 | ZDNet.com Quote:
- 1 GHz or faster 32-bit (x86) or 64-bit (x64) processor
- 1 GB of RAM (32-bit)/2 GB of RAM (64-bit)
- 16 GB of available disk space (32-bit)/20 GB (64-bit)
- DirectX 9 graphics device with Windows Display Driver Model 1.0 or higher driver
and your card only supports DirectX 8.1,
Radeon™ 9200 Series Quote:
- Full support for DirectX ® 8.1 programmable pixel and vertex shaders in hardware
- 1.4 pixel shaders support up to 22 instructions and up to 6 textures per rendering pass
- 1.1 vertex shaders support vertex programs up to 128 instructions
- Complete feature set also supported in OpenGL ® via extensions
- Programmable shaders provide enhanced 3D effects in over 100 existing and upcoming
Basically your options are,
- live with the card and whatever
driver Windwos 7 installs for it
- get a card that meets the minimum requirements for Windows 7
- give up on Windows 7 until you have a computer that meets the requirements in all ways.
