AMD has moved a number of DX9 ATI Radeon? graphics accelerators products to a legacy driver support structure. This change impacts Windows XP, Windows Vista, and Linux distributions. AMD has moved to a legacy software support structure for these graphics accelerator products in an effort to better focus development resources on future products.

The following products have been moved to the legacy software support structure (including Mobile and All-in-Wonder Variants):

ATI Radeon 9500 Series
ATI Radeon 9550 Series
ATI Radeon 9600 Series
ATI Radeon 9700 Series
ATI Radeon 9800 Series
ATI Radeon X300 Series
ATI Radeon X550 Series
ATI Radeon X600 Series
ATI Radeon X700 Series
ATI Radeon X800 Series
ATI Radeon X850 Series
ATI Radeon X1050 Series
ATI Radeon X1300 Series
ATI Radeon X1550 Series
ATI Radeon X1600 Series
ATI Radeon X1650 Series
ATI Radeon X1800 Series
ATI Radeon X1900 Series
ATI Radeon Xpress Series
ATI Radeon X1200 Series
ATI Radeon X1250 Series
ATI Radeon X2100 Series

Note: AMD’s DirectX 9 ATI Radeon graphics accelerators are not officially supported under Windows 7. If the user chooses to, they can install the ATI Catalyst Windows Vista graphics driver under Windows 7. Please be aware that none of the new Windows 7 graphics driver (WDDM 1.1) features are supported (as the Windows Vista level graphics driver is limited to WDDM 1.0 level support). Using the ATI Catalyst Windows Vista driver under Windows 7 is not officially supported by AMD, and as such AMD will not provide any form of customer support for users running in this configurATIon

AMD may periodically provide Windows XP and Windows Vista driver updates (for the products listed above) for critical fixes only. No new features will be provided in future driver updates. The Linux ATI Catalyst? driver will only be supported in Linux distributions prior to February 2009 for the legacy products listed above.

Any customers using a combinATIon of a ATI Radeon? HD 2000 Series, ATI Radeon? HD 3000 Series, or ATI Radeon? HD 4000 Series product with any of the legacy products listed above in a single PC system must use the ATI Catalyst 9.3 or earlier driver. All future ATI Catalyst? releases made available past the ATI Catalyst? 9.3 release will not include support for the legacy products listed above or any of the features associated with those legacy products.

问题:
1.识别不了显卡芯片类型,适配器字符串出现乱码

3.OpenGL驱动无法使用:有声音无图像

系统默认驱动程序版本:8.56.1.15

解决方法:
1.重启计算机,按F8选择进入”修复计算机”,在命令提示符下执行命令
rd C:\\Windows\\System32\\DriverStore\\FileRepository\\ATIilhag.inf_x86_neutral_7d512c02e72ebd25 /s /q
rd C:\\Windows\\System32\\DriverStore\\FileRepository\\ATIriolh.inf_x86_neutral_cdb610d99bcbc631 /s /q
2.重启计算机,按F8选择进入”安全模式”

启动”设备管理器”

顺便说一下，这个BLOG风格蛮漂亮的，只可惜是PHP程序，呵呵，不知道主程序用哪的？呵呵

最开始前一个WIN7 系统无法按F8,因为是系统问题,要重新换个版本就可以了
WIN7 所有驱动都保存在c:\\drivers中
ati 9550装win7时显卡会自动安装驱动后有问题,显卡显示信息乱码
装完后能达到3.4AERO.

opengl使用不正常,要按照网上的方法

先删掉文件夹(win7安全模式删除不了就用pe系统剪切出来，这个文件夹每个系统好像都不一样的，但是ATIilhag.inf_x86_neutral这部分是相同的，根据自己名字不同删除),
在安全模式卸载显卡,再重新更新驱动
网上的方法有2点注意,1.他先安装的ATI 9550   9.11的催化程序,2,最后一步更新视频驱动是在c:\\drivers中驱动,不是网上驱动

微软自动安装驱动-删除文件夹-安全模式删除驱动-正常启动装ati  9.11驱动-如果aero没出现，很有可能是没选win7 aero主题，而是basic主题，换下即可
 

其实是不是微软自己默认装好后，什么都不用管，直接装ati驱动，监测性能分，然后用aero主题即可？没试过
