a谁有md hd 6650m xp驱动

AMD和笔记本官方都不提供XP驱动，修改INF可以支持Mobility Radeon 5650/6470/6500M/6600M等新显卡：
1. 先下载官方驱动(点单独下载→显示驱动)，直接双击解压(取消安装)。

2. 打开解压以后的CX116950.inf(XP_INF目录下面，新版驱动文件名可能不一样)，在[ATI.Mfg.NTx86]字段加几行(你是5650可以只加一行)：
"ATI Mobility Radeon HD 5400 Series" = ati2mtag_Manhattan, PCI\VEN_1002&DEV_68E0
"ATI Mobility Radeon HD 5400 Series " = ati2mtag_Manhattan, PCI\VEN_1002&DEV_68E1
"ATI Mobility Radeon HD 5600/5700 Series" = ati2mtag_Manhattan, PCI\VEN_1002&DEV_68C1
"ATI Mobility Radeon HD 5700 Series" = ati2mtag_Manhattan, PCI\VEN_1002&DEV_68C0
"ATI Mobility Radeon HD 5800 Series" = ati2mtag_Manhattan, PCI\VEN_1002&DEV_68A0
"ATI Mobility Radeon HD 5800 Series " = ati2mtag_Manhattan, PCI\VEN_1002&DEV_68A1
"AMD Radeon HD 6300M Series" = ati2mtag_Manhattan, PCI\VEN_1002&DEV_68E4
"AMD Radeon HD 6400M Series" = ati2mtag_Manhattan, PCI\VEN_1002&DEV_6760
"AMD Radeon HD 6600M Series" = ati2mtag_Manhattan, PCI\VEN_1002&DEV_6741
"AMD Radeon HD 6700M Series" = ati2mtag_Manhattan, PCI\VEN_1002&DEV_6740
3. 从设备管理器右键视频控制器更新驱动，浏览CX116953.inf所在目录，下一步完成。
