How to make WINDOWS2003 use 4G or more memory

Many friends just installed WINDOWS2003 Enterprise Edition in order to use more than 4G memory, but after installing it, they found that the memory used by the system is only 3G, is it WINDOWS2003 Enterprise Edition 32 bit Does it support intrinsicity greater than 4G? Actually not! “newswan” The post was very good. For a friend who is not good at English, it is still a bit difficult to understand. Below, simply give you a little reference, 2003 is to support more than 4G of memory, but in the default situation is limited by 32-bit, can not use more than 4G of memory, to fully use more than 4G of memory depends on PAE and AWE Resolve the memory usage limit of the 4G range inherent to 32-bit operating systems. PAE is the physical address extension, and the Windows 2003 Memory Manager uses PAE to provide more physical memory to the program. The program itself does not know the actual memory size. All memory management and PAE memory allocation are handled by the memory manager, regardless of the program being run. AWE, the address windowing extension, is a set of application programming interfaces (APIs) for memory manager functions that enable programs to address more memory — 4 GB of memory than standard 32-bit addressing. Note for PAE and AWE: PAE, physical address extension, is a feature of the Windows 2003 memory manager, which means that it is system-based, and AWE, the address windowing extension, is a set of application programming interfaces (APIs). ). In Windows Server 2003, PAE is automatically enabled when the server uses hot-swappable memory devices. For ordinary people, it is impossible to use expensive server machines. You must use the /PAE switch in the Boot.ini file to enable PAE. Use more than 4GB of memory. The following is an example of a Boot.ini file with the PAE switch added: [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(2)\\WINDOWS [operating systems] multi( 0) disk(0)rdisk(0)partition(2)\\WINDOWS="Windows Server 2003, Enterprise" /fastdetect /PAE
