How to Enable PAE in x86 32-bit Windows Server 2003 and 2000 to Use Large 4GB or More RAM Memory如何啟用PAE在x86 32位元Windows Server 2003和2000年使用大型4 GB的或更多的RAM記憶體

After installing Windows 2000 (Datacenter Server or Advanced Server) or Windows 2003, system properties shows that only around 3.37 GB of physical memory (RAM) is available for application and system use, although 4 GB or more RAM modules have been installed, and BIOS can correctly identifies the full installed size of physical memory, which means that the motherboard and x86 or x64 CPU processor can support more than 4 GB of physical memory.後安裝Windows 2000 （ Datacenter Server的或Advanced Server ）或Windows 2003 ，系統屬性顯示，只有大約3.37 GB的物理內存（ RAM ）是可供應用程序和系統的使用，雖然4 GB或更多的RAM模塊已安裝，和BIOS能夠正確識別全部安裝了大小的物理內存，這意味著主板和x86或x64的CPU處理器，能夠支持4 GB以上的物理內存。

32-bit Windows operating system depends on PAE ( 32位Windows操作系統，取決於的PAE （ Physical Address Extension物理地址擴展 ) feature to use more than 4 GB of physical memory. ）功能，使用超過4 GB的物理內存。 On most Windows 2000 and Windows Server 2003 system, especially those run in NUMA mode on a NUMA-capable computer.大多數Windows 2000和Windows Server 2003系統，尤其是那些運行在努瑪模式對一，努瑪能力的計算機。 PAE is disabled by default. PAE是默認情況下禁用。 PAE is enabled by default only if DEP (啟用PAE默認情況下，只有如果DEP的（ Data Protection Execution數據保護的執行 ) is enabled on a computer that supports hardware-enabled DEP, or if the computer is configured for hot-add memory devices in memory ranges beyond 4 GB. ）是使一台計算機上支持硬件DEP的啟用，或如果計算機配置為熱添加內存設備的記憶體範圍以外的4 GB的。

Thus, if PAE is not enabled in Windows 2000 and Windows Server 2003 (for example, if DEP is turned off by administrator), the system may not able to detect, identify and see more than 4GB memory, and will have to allocate slightly more than 3GB of memory for system and application only as some memory address space has to be reserved and mapped for system devices and peripherals.因此，如果PAE是未啟用在Windows 2000和Windows Server 2003 （例如，如果DEP的是關閉的，由管理員） ，系統可能無法偵測，識別和見4GB以上記憶體，以及將不得不撥出略多超過3 Gb的內存為系統和應用，只有一些記憶體位址空間要保留和映射為系統設備和外設。

To enable PAE in Windows Server 2003 and Windows 2000 (and Windows XP), append the要啟用PAE在Windows Server 2003和Windows 2000 （和Windows XP ） ，附加 /PAE / PAE的 switch to the end of the line of operating system in the Boot.ini file.切換到年底，該行的作業系統，在Boot.ini文件中。 To disable PAE, use the /NOPAE switch.要禁用的PAE ，使用/ nopae開關。 The Boot.ini normally located in the root folder (ie C:\) with Read-Only and Hidden attributes, which are required to be removed before the file can be edited.在Boot.ini通常位於根文件夾中（即為C ： \ ）與只讀和隱藏屬性，這是需要被遣送離境之前，該文件可以進行編輯。

For example,舉例來說，

Original Boot.ini:原有BOOT.INI ：

[boot loader]的[ Boot Loader ]
timeout=0超時= 0
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT默認=多（ 0 ）磁盤（ 0 ） rdisk （ 0 ）分區（ 1 ） \ winnt
[operating systems] [操作系統]
multi(0)disk(0)rdisk(0)partition(1)\WINNT=”Microsoft Windows 2000 Advanced Server”多（ 0 ）磁盤（ 0 ） rdisk （ 0 ）分區（ 1 ） \ winnt = “微軟的Windows 2000 Advanced Server ”
/fastdetect / fastdetect

Change the Boot.ini to become:更改Boot.ini成為：

[boot loader]的[ Boot Loader ]
timeout=0超時= 0
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT默認=多（ 0 ）磁盤（ 0 ） rdisk （ 0 ）分區（ 1 ） \ winnt
[operating systems] [操作系統]
multi(0)disk(0)rdisk(0)partition(1)\WINNT=”Microsoft Windows 2000 Advanced Server”多（ 0 ）磁盤（ 0 ） rdisk （ 0 ）分區（ 1 ） \ winnt = “微軟的Windows 2000 Advanced Server ”
/fastdetect /PAE / fastdetect / PAE的

For Bootcfg command, use:為bootcfg命令，使用：

bootcfg /raw "/pae" /A /ID 1 bootcfg /原料“ / PAE的” / 1 /編號1

Restart the computer after modification to make the change effective.重新啟動計算機，改性後作出有效的改變。

Note that even with PAE enabled, there is still memory limit imposed by the operating system itself.請注意，即使與PAE的啟用，還有記憶體的限制，由操作系統本身。 The table below list the maximum memory support with PAE enabled for Windows 2000, Windows Server 2003 and Windows XP.下面的表格列出，最大記憶體的支持與PAE的啟用對於Windows 2000 ， Windows Server 2003和Windows XP 。 Most 32-bit client based Windows operating system, such as Windows XP and Windows Vista (see大部分的32位客戶端基於Windows操作系統，如Windows XP和Windows Vista （見 way to use large memory of more than 4GB in 32-bit Windows Vista創新方法，可使用大容量存儲器的4GB以上，在32位的Windows Vista ), has OS level limit that restricts the maximum amount of memory able to be used to 4GB. ） ， OS的水平限制，限制的最大內存量能用來為4GB 。
