入手阶段,先收集了两个driver的loader的代码,两者都是通过从ntdll.dll的导出的内核函数进行动态的驱动加载,这两个方式都是通常比较常见的方式.我这里对收集到的代码进行了整理,分离,修改,并在我机器WinXP SP2+VS 2005下编译测试.
ps: 更常见的通过SCM加载驱动的代码就不表了,其实最后就是调用ZwLoadDriver.

最后附上Windows NT 2000 Native API Reference里的几段相关的文字:
SystemLoadAndCallImage
Unlike ZwLoadDriver,which loads the module in the context of the system process,ZwSetSystemInformation loads the module and invokes the entry point in the context of the current process.

ZwLoadDriver
SeLoadDriverPrivilege is required to load a driver.
StartService directs the Service Control Manager process to
