求教修改显卡驱动安装信息文件详细方法

很简单的一个办法，将nvtd.inf中的下方两部分原内容删掉后添加6行：
[NVIDIA_SetA_Devices.NTamd64.6.0]
%NVIDIA_DEV.0A70.01% = Section001, PCIVEN_10DE&DEV_0A70&SUBSYS_0CDD105B
%NVIDIA_DEV.0A73.03% = Section001, PCIVEN_10DE&DEV_0A73&SUBSYS_0D5E105B
%NVIDIA_DEV.0CAF.01% = Section005, PCIVEN_10DE&DEV_0CAF&SUBSYS_0CDD105B

[NVIDIA_SetA_Devices.NTamd64.6.1]
%NVIDIA_DEV.0A70.01% = Section002, PCIVEN_10DE&DEV_0A70&SUBSYS_0CDD105B
%NVIDIA_DEV.0A73.03% = Section002, PCIVEN_10DE&DEV_0A73&SUBSYS_0D5E105B
%NVIDIA_DEV.0CAF.01% = Section006, PCIVEN_10DE&DEV_0CAF&SUBSYS_0CDD105B

这没看明白，到底是哪个下方的内容，谁能告诉我详细点的吗，不胜感激!!
