How to fully use the 4 GB of RAM in my Laptop under Ubuntu 9.10 - 32-bit

I have a Toshiba A100, which I upgraded to 4 GB of RAM. The hardware startup indeed shows 4 GB of RAM, and I recently installed Windows 7, just to see how it behaves on it. So far so good, it displays 4 GB of RAM. Not that I tried to use it all, but it displays it. Previously under XP, I also would see 4 GB of RAM.

"For PAE to work, you will need both system and application that supports it. System you have (kernel), but not all applications will see it since they are usually not compiled that way.

Only applications where developer took extra steps will be able to use that memory. Usually those applications are among ones that are memory-hungry. MySQL as standard example springs to mind.

Although your system and most of your applications only see 3GB, you can be sure that some applications (e.g. MySQL) will know how to use it."
