WDM驱动实操No.1_ven8086网卡驱动

一、虚拟驱动如何绑定一个实际硬件安装该驱动？

1、实际硬件：网卡

硬件ID：PCI\VEN_8086&DEV_10D3
对应于虚拟驱动INF文件中的：
%wdk_s2_c13_test1_driver.DeviceDesc%=Root\wdk_s2_c13_test1_driver ; TODO: edit hw-id
修改：只要将Root\wdk_s2_c13_test1_driver 变更为 PCI\VEN_8086&DEV_10D3即可
%wdk_s2_c13_test1_driver.DeviceDesc%=wdk_s2_c13_test1_driver_Device, PCI\VEN_8086&DEV_10D3
;Root\wdk_s2_c13_test1_driver ; TODO: edit hw-id
拓展：也就是改变驱动中对应的硬件ID就可以绑定对应的实际硬件；在项目中，一个驱动可能需要适配不用的设备，就是通过设备的硬件ID进行识别区分的。

然后将网卡驱动更新之后：

就会将设备与微软的驱动绑定；

2.2 理解启动设备和禁用设备

因为是即插即用，我们首先得将驱动和设备区分开；驱动是一种程序，躺在内存中。当有一个设备插入（也相当于我们启用一个设备），那么就会去找驱动程序，找到后，驱动就开始为设备服务了。也就是，一个驱动可以为很多不同时段插入的设备服务，也就是加载驱动。加载驱动中就有创建设备，其实就是为实际的硬件创建一个软件的形式，使得能与设备进行交互，所以启用设备都会创建一个设备对象。
