Nvidia笔记本显卡驱动最新版，WinRAR，记事本
用WinRAR打开266.58_notebook_winxp_32bit_international_whql，解压Display.Driver整个目录。
打开设备管理器(运行devmgmt.msc)，双击视频控制器，点击详细信息，记下设备范例ID，类似“PCI\VEN_10DE&DEV_1050”，从下面的列表可以看出每款显卡对应的设备ID。
打开nvac.inf，在[NVIDIA_Devices]字段添加几行(根据你的设备ID也可以只用一行)： %NVIDIA_DEV.1050.01% = Section001, PCI\VEN_10DE&DEV_1050 %NVIDIA_DEV.0DF7.01% = Section001, PCI\VEN_10DE&DEV_0DF7 %NVIDIA_DEV.0DED.01% = Section001, PCI\VEN_10DE&DEV_0DED %NVIDIA_DEV.0DEC.01% = Section001, PCI\VEN_10DE&DEV_0DEC %NVIDIA_DEV.0DEB.01% = Section001, PCI\VEN_10DE&DEV_0DEB %NVIDIA_DEV.0DF4.01% = Section001, PCI\VEN_10DE&DEV_0DF4 %NVIDIA_DEV.0DF5.01% = Section001, PCI\VEN_10DE&DEV_0DF5 %NVIDIA_DEV.0DF6.01% = Section001, PCI\VEN_10DE&DEV_0DF6 %NVIDIA_DEV.0DD6.01% = Section001, PCI\VEN_10DE&DEV_0DD6 %NVIDIA_DEV.0DCD.01% = Section001, PCI\VEN_10DE&DEV_0DCD %NVIDIA_DEV.0DCE.01% = Section001, PCI\VEN_10DE&DEV_0DCE
在[Strings]字段添加几行： NVIDIA_DEV.1050.01 = 'NVIDIA GeForce GT 520M' NVIDIA_DEV.0DF7.01 = 'NVIDIA GeForce GT 520M' NVIDIA_DEV.0DED.01 = 'NVIDIA GeForce GT 520M' NVIDIA_DEV.0DEC.01 = 'NVIDIA GeForce GT 525M' NVIDIA_DEV.0DEB.01 = 'NVIDIA GeForce GT 555M' NVIDIA_DEV.0DF4.01 = 'NVIDIA GeForce GT 540M' NVIDIA_DEV.0DF5.01 = 'NVIDIA GeForce GT 525M' NVIDIA_DEV.0DF6.01 = 'NVIDIA GeForce GT 550M' NVIDIA_DEV.0DD6.01 = 'NVIDIA GeForce GT 550M' NVIDIA_DEV.0DCD.01 = 'NVIDIA GeForce GT 555M' NVIDIA_DEV.0DCE.01 = 'NVIDIA GeForce GT 555M' 保存文件。
设备管理器右键视频控制器→更新驱动程序→从列表或指定位置安装→浏览，指定Display.Driver，下一步，完成。
第三、四步可以直接找网友修改的INF文件，据说基于nvac.inf和nv4_disp.inf的驱动相对成熟(个人有备份这些INF)。
