When the processor acesses a resource that falls into these address ranges, the request doesn't go to RAM, it goes to the PCI (or PCI-e or AGP) bus and is serviced by the appropriate card. The peripheral doesn't care which addresses are used, but Windows places them at the top of the 32-bit address space, which translates into less available RAM for programs. If Vista still cannot recognize all of your memory, then you may have to go into the BIOS and disable some of the memory mapping. This is usually found in the Advanced Chipset section of your BIOS and is probably called Memory Mapped I/O (MMIO) but there is no standard terminology for this feature. You may have to turn to your motherboard's manual to determine what this feature is called, and this feature may not be available at all. Memory Remapping changes the address space for peripherals to the 4.0GB to 4.5GB address space, so Windows may report that you have 4.5GB of memory when you only have 4GB installed with this enabled.

That is a marketing decision. To use more than 4 GB with PAE you need Windows server OS. You can get Vista to display more than 4 GB in Control Panel, but it will still use 4 GB at most.
