去Nvidia官方下载移动显卡公版驱动，百度“Notebook Release 265 XP”就有下载地址了，驱动文件是266.58_notebook_winxp_32bit_international_whql.exe。

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。
