So you may have 4GB installed, but XP is not able to address 1GB because
of your Video card and other components, etc on your computer. I'm not
making this up.

Current operating systems, such as Microsoft® Windows® XP, can only use
a maximum of 4 GB of address space; however, the amount of memory
available to the operating system is less than 4 GB. Certain components
within the computer require address space in the 4-GB range. Any address
space reserved for these components cannot be used by computer memory.
