I think this is limitation of your 32-bit operation system. MS Windows 32bit Standard Edition can handle only 4GB of RAM. Enterprise edition can handle more then 4GB of RAM with Physical Address Extension (/PAE) switch.

what did you mean about PAE switch?

[Kedd Guyton]

The /PAE switch is set in the C:\boot.ini.
