Don't we have this written down somewhere? Sigh, OK.
Your 32-bit Windows has 4GB of available memory addresses. It needs some of these addresses for other things, such as video, motherboard resources, etc.
In your case, once everything is assigned, your OS has 2.99GB of addresses left over to use with the physical memory.
This is why people get 64-bit operating systems... because they get more address space. The extra system addresses can be assigned above the 4GB mark, leaving a 4GB chunk free to be assigned to your RAM.

I'm sorry, I am not sure if it has been addressed or not but my apologies for not searching first. I appreciate your help. I have a 64bit desktop system and way more memory is usable. Thanks again.
