这个图里,boot.ini里没有/PAE,但又显示物理地址扩展,而且系统也认全内存,分明是打开了PAE的结果,想来 ... 6 b; B6 t9 v. H1 i3 J3 o
兄弟你out了吧,其实在Windows Server 2003 SP1或XP SP2之后,因为内核默认是打开DEP功能的,而DEP功能又是依赖PAE的,所以内核也会默认打开PAE,并不需要在boot.ini里写入。除非你的CPU很旧,不支持硬件DEP,那PAE就是关的,因为DEP也没开。: d m6 h6 {* g3 E L6 n

微软的说明:

On a computer that supports hardware-enabled Data Execution Prevention (DEP) and is running a 32-bit version of the Windows operating system that supports DEP, PAE is automatically enabled when DEP is enabled3 l* s; J7 _/ A
