如题所述

Answer 1

【问题描述】:WinXP系统NvidiaGT520M/540M独立显卡驱动安装【原因分析】：安装独立显卡驱动【简易步骤】：通过修改INF文件来安装新版驱动。【解决方案】:本方法适用Nvidia Geforce GT540M、GT520M、GT555M等最新500M系列笔记本显卡，但是双显卡切换机型在XP系统下不支持禁用集显只用独显(N卡运算必须通过集显端口输出)，只有屏蔽了核芯显卡只用独显的机型才能驱动。采用GT540M笔记本：神舟a560-i7d1、华硕A43S、Acer 4750G（2412G50Mnkk）采用GT555M笔记本：联想Y470N-ISE、联想Y570NT-ISE采用GT520M笔记本：联想Z470A-ITH、Acer 4743G（482G50Mnkk）1. 去Nvidia官方下载【移动显卡公版驱动】，搜索【Notebook Release 265 XP】就有下载地址了，驱动文件是【266.58_notebook_winxp_32bit_international_whql.exe】。2. 用解压缩工具打开【266.58_notebook_winxp_32bit_international_whql】，解压【Display.Driver】整个目录。3. 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。如图1图14. 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)：如图2 %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图25. 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。如图3图36. 【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。如图4图4
