呵呵，ExecRing0Proc 这段程序甚妙，先得到gdt，然后构造一个调用门call gate's ,使程序从用户模式(ring 3)进入内核模式(ring 0)。进入内核模式之后，就可以没有限制地对系统干任何勾当。这段程序确实为高手所为，在下佩服得紧。
至于读硬盘序列号之类，只不过是在内核模式下的一个I/O应用罢了。
其实在NT/2000下读取硬盘序列号只要打开\\.\PhysicalDriveX(X:设备号0~26）设备，然后用DeviceIoControl()就可以读取了，不需要绕ring0这么一个大圈子

这个程序也可以C语言实现，不过中间必须嵌入几条汇编的指令，如sgdt GdtLimit
但还是用c来写更方便，例如：
call @f
db "ZwOpenSection",0
@@:
push NtdllMod
call GetProcAddress
mov ebx,eax ;ebx=ZwOpenSection
push esi ;esi->ObjAttr
push SECTION_MAP_READ or SECTION_MAP_WRITE
lea edi,hSection
push edi ;edi->hSection
call eax ;

用c的话只要一句就可以了
ZwOpenSection(&hSection,SECTION_MAP_READ or SECTION_MAP_WRITE,ObjAttr)；
因此懂汇编，然后用C/C++编程，是成为高手的捷径

win32位汇编，真的很不错，业余的时间，全都投进去了

唐明 · 发表于 2003-11-26 19:36:00

要能有台机器试一下多好，学汇编还从没想过去ring0，也感觉没哪个必要。
现在闲着真相试试。这片文章我在家保存了有快一年了。不用感觉可惜了。一直停着不用，我都快忘了那些曾经那些依稀的记忆了。水能给我一台电脑，我力马高喊：有你这么富的吗？

不是吧,这个是轻描淡写编程论坛的斑竹写的
