determine PAE in windows 2003
How to determine PAE already configured in windows 2003 Enterprise
When i checked Windows system properties, i able to see that the General tab of the System Properties lists Physical Address Extension at the end of the Computer section.
But when i check the actual Boot.ini in notepad, i dont see any extension has been added " /PAE"

hi, im running 32 bit version
See the article at the link below for a short tutorial on how to enable PAE.

And note the following:
It’s worth noting that if you have DEP (Data Execution Protection) turned on then PAE will be turned on by default. DEP is on automatically in Windows Server 2003 SP1 - you’ll see the /noexecute=[policy level] in the boot.ini
Note that this probably won't make any change in the system performance, though. PAE is useful only when (a) there is more than 4 GB installed, and (b) there are multiple applications running which each take up significant memory. In a 32-bit system no process can use more than 3 GB of memory no matter how much memory is installed. This is a hardware limitation -- the 32 bit address space is 4 GB, the video adapter takes up the 3 GB to 4 GB memory space, so no process can use more than 3 GB.

How much memory does the system have, what applications are running? See Dr.Klahn re system with more than 4GB

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
If you are running a 64-bit version, then there is no PAE. PAE is a feature found only in x86 (32-bit) hardware.
