Vista SP2 32bit 已支持4GB. 附xp,vista, vista sp1实现方法

昨晚装完vLite精简后的Vista SP2 32bit, 发现已支持4GB内存了（有空上图），但我的母板还是显示3.xxGB.
附xp,vista, vista sp1实现方法:（简单英文，有心人帮翻译吧）

But very few people know that even 32-bit systems can support up to 4GB of RAM.This can be done by enabling the PAE(Physical Address Extension) on your PC.Now a days almost all processors support PAE.

How to enable PAE on XP:

To enable PAE in Windows XP you have to edit the boot.ini file. Open boot.ini file. It will be there in your system drive. Suppose your OS is installed in C drive then go to run and type c:\boot.ini and hit enter.Add “/ PAE” at the end of the file.

It would look something like this:
multi (0) disk (0) rdisk (1) partition (1) \ WINDOWS = “Microsoft Windows XP Professional” / noexecute = OptIn / fastdetect / PAE

Don’t change anything else in boot.ini or your PC will not boot.Just add / PAE at the end of the line.

Now restart your PC and check if your computer is showing 4 GB RAM. To do this right click on My computer and select properties.Click on general tab and see if it is showing 4GB or not. If it shows then it means that you have done everything correctly and you can use complete 4Gb of your RAM.

Enable PAE under Vista:
It is very easy to enable PAE under Vista. Open cmd and type
BCDEdit / set PAE forceenable
Now it should show 4GB of RAM in Vista.

Warning:Use PAE only if you really have 4GB of RAM or your PC may not work properly. Or if you have got some extra money I will recommend you to go for 64-bit system.

用强制打开PAE的方法来管理大内存是要付出代价的——用性能的损耗换取容量的增加。

旧理念了。win7, vista sp2都以支持到4gb了。
