Why would less than the full 4.0 GB show up on the control
panel->System dialogbox?

Because drivers, videocards and interfaces may claim memory
on boot/startup.
Whats left is your 3.24 GB.

There is limited address space in a 32 bit OS, to access all the
hardware resources available. It is like having 5GB worth of
hardware, and only 4GB worth of address space. 1GB of it is then
not addressable. And the way it works is, real hardware resources
like system buses, are assigned address space first. The "leftovers"
are used for memory. And the end result, is only 3.24GB of your
memory is visible. 0.76GB of it, cannot be reached.

If you were to add a video card to the computer, you'd find a further
reduction in the free memory reported, due to the address space required
by the new video card.

Without PAE a 32 bit OS can only address about 3.2 gigs of memory

if you need 4 gigs or more...you will need to use a 64bit OS

It says that it has Physical Address Extension on the same
screen that says that it has 3.24 GB of RAM.
