If you are using XP SP2 you can use 3GB of RAM.
Right Click on “My Computer”
“Properties”
“Advanced”
Under Startup and recovery click the settings tab
Click on “edit”
Notebook will open your boot.ini file.
This is your boot.ini file. SAVE A COPY FIRST!
Then on the last line add “3GB” at the end so your file looks like this:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS=”Microsoft Windows XP Professional” /noexecute=optin /fastdetect/3GB
Then when you restart your machine, AE will use 3GB instead of 2GB.
Good luck
