老机器，老显卡了。

但是980M是的硬件ID是特制的，需要修改，官网驱动说找不到硬件之类，无法安装

最近为了学pytorch，安装cuda10 重装系统。重新回忆一遍。

蓝天这个980M，在设备管理器里查看的硬件ID是

PCI\VEN_10DE&DEV_13D7&SUBSYS_71021558&REV_A1

https://www.nvidia.cn/Download/index.aspx?lang=cn

比如451.67-notebook-win10-64bit-international-dch-whql.exe

 解压缩到文件夹

右键解压缩到451.67-notebook-win10-64bit-international-dch-whql 文件夹

Display.Driver 下

打开

nvcvi.inf （蓝天的配置文件）

搜索980M

找到

NVIDIA_DEV.13D7.0376.1558 = "NVIDIA GeForce GTX 980M"NVIDIA_DEV.13D7.0870.1558 = "NVIDIA GeForce GTX 980M"NVIDIA_DEV.13D7.5281.1558 = "NVIDIA GeForce GTX 980M"NVIDIA_DEV.13D7.6540.1558 = "NVIDIA GeForce GTX 980M"NVIDIA_DEV.13D7.6541.1558 = "NVIDIA GeForce GTX 980M"NVIDIA_DEV.13D7.6556.1558 = "NVIDIA GeForce GTX 980M"NVIDIA_DEV.13D7.6780.1558 = "NVIDIA GeForce GTX 980M"NVIDIA_DEV.13D7.6781.1558 = "NVIDIA GeForce GTX 980M"NVIDIA_DEV.13D7.7481.1558 = "NVIDIA GeForce GTX 980M"NVIDIA_DEV.13D7.7500.1558 = "NVIDIA GeForce GTX 980M"NVIDIA_DEV.13D7.7502.1558 = "NVIDIA GeForce GTX 980M"NVIDIA_DEV.13D7.7700.1558 = "NVIDIA GeForce GTX 980M"NVIDIA_DEV.13D7.7702.1558 = "NVIDIA GeForce GTX 980M"

可以看见 目前支持各种版本的980M 唯独没有7102的。 那么只要把其中某个全部替换成7102就可以了。

但是这些版本的980M区别是什么呢？

在文件开头100多行，可以找到

%NVIDIA_DEV.13D7.0376.1558% = Section010, PCI\VEN_10DE&DEV_13D7&SUBSYS_03761558 %NVIDIA_DEV.13D7.0870.1558% = Section011, PCI\VEN_10DE&DEV_13D7&SUBSYS_08701558 %NVIDIA_DEV.13D7.5281.1558% = Section012, PCI\VEN_10DE&DEV_13D7&SUBSYS_52811558 %NVIDIA_DEV.13D7.6540.1558% = Section013, PCI\VEN_10DE&DEV_13D7&SUBSYS_65401558 %NVIDIA_DEV.13D7.6541.1558% = Section014, PCI\VEN_10DE&DEV_13D7&SUBSYS_65411558 %NVIDIA_DEV.13D7.6556.1558% = Section012, PCI\VEN_10DE&DEV_13D7&SUBSYS_65561558 %NVIDIA_DEV.13D7.6780.1558% = Section013, PCI\VEN_10DE&DEV_13D7&SUBSYS_67801558 %NVIDIA_DEV.13D7.6781.1558% = Section014, PCI\VEN_10DE&DEV_13D7&SUBSYS_67811558 %NVIDIA_DEV.13D7.7481.1558% = Section012, PCI\VEN_10DE&DEV_13D7&SUBSYS_74811558 %NVIDIA_DEV.13D7.7500.1558% = Section015, PCI\VEN_10DE&DEV_13D7&SUBSYS_75001558 %NVIDIA_DEV.13D7.7502.1558% = Section016, PCI\VEN_10DE&DEV_13D7&SUBSYS_75021558 %NVIDIA_DEV.13D7.7700.1558% = Section015, PCI\VEN_10DE&DEV_13D7&SUBSYS_77001558 %NVIDIA_DEV.13D7.7702.1558% = Section016, PCI\VEN_10DE&DEV_13D7&SUBSYS_77021558

可以看见 不同SUBSYS的 980M 对应 不同的 Section， 大概从Section010-Section016 ， 有的SUBSYS是用的同样的Section016

不同的section前面都差不多，关键是后面的各种NVSupport 不一样

罗列一下

[Section010]……

NVSupportAnsel = 1NVSupportDisplayUpdate = 1NVSupportGFExperienceOEM = 1NVSupportGFExperienceUDA = 1NVSupportPhysx = 1NvSupportTelemetry = 1

……

[Section011]……NVSupportAnsel = 1NVSupportDisplayUpdate = 1NVSupportGFExperienceOEM = 1NVSupportGFExperienceUDA = 1NVSupportPhysx = 1NvSupportTelemetry = 1

……

[Section012]……NVAllowMCVirtualAudioPreStage = 0NVSupportAnsel = 1NVSupportDisplayUpdate = 1NVSupportGFExperienceOEM = 1NVSupportGFExperienceUDA = 1NVSupportPhysx = 1NvSupportMSHybrid = 1NvSupportTelemetry = 1

……

[Section013]NVAllowHDAudioPreStage = 1NVAllowMCVirtualAudioPreStage = 0NVRemoveDisplayPhantoms = 1NVSupportAnsel = 1NVSupportDisplayUpdate = 1NVSupportGFExperienceOEM = 1NVSupportGFExperienceUDA = 1NVSupportPhysx = 1NvSupportMSHybrid = 1NvSupportTelemetry = 1

[Section014]……NVRemoveDisplayPhantoms = 1NVSupportAnsel = 1NVSupportDisplayUpdate = 1NVSupportGFExperienceOEM = 1NVSupportGFExperienceUDA = 1NVSupportPhysx = 1NvSupportTelemetry = 1

……

[Section015]……NVSupportAnsel = 1NVSupportDisplayUpdate = 1NVSupportGFExperienceOEM = 1NVSupportGFExperienceUDA = 1NVSupportPhysx = 1NvSupportTelemetry = 1

……

[Section016]……NVSupportAnsel = 1NVSupportDisplayUpdate = 1NVSupportGFExperienceOEM = 1NVSupportGFExperienceUDA = 1NVSupportPhysx = 1NvSupportTelemetry = 1

……

现在比3XX时代配置项改变了好多，没有NVSupportOptimus这个了。

可以看到Section013是支持功能最多的。

在开头查到

%NVIDIA_DEV.13D7.6780.1558% = Section013, PCI\VEN_10DE&DEV_13D7&SUBSYS_67801558 

也就说，查找替换这个即可。

为了保证查找替换准确，分成2步，包含前面的13D7表示是980M

查找

13D7.6780.1558

替换

13D7.7102.1558

查找

DEV_13D7&SUBSYS_67801558

替换

DEV_13D7&SUBSYS_71021558

安装驱动需要禁用强制签名

win10有改变，不能在启动时按F8 高级启动

而是在重启前，按住shift，点重启。 

选择高级启动，启动项改变之类

然后重启，就可以看见1个菜单，

选择禁用驱动签名（大概是数字7）

安装驱动的时候会弹出：

 选择第2个，就OK了

否则还是会更新成2017的很老的驱动。不支持cuda 10.2了

反正也是老机器了。自己维护驱动就好。

Win+ R 运行输入 gpedit.msc 打开组策略编辑器

进入 计算机配置 - 管理模板 - Windows 组件 - Windows 更新 - Windows 更新不包括驱动程序

选择 "已启用" 并确定

注意在大版本升级比如1090->2004之后，可能也得重新安装驱动
