That is something the system builder determines and is dependent on how the hardware is set up, whether it allows address space remapping and whether the system firmware actually makes use of it and it is all essentially baked into the system design and setup beyond the users access. I do remember some systems towards the end of the 32-bit era that did allow address space remapping that allowed some systems to make more use of the area beyond 3GB, but support was patchy at best. 64-bit made it essentially pointless. | |

The hardware on this machine will never change, so if it was possible, could I theoretically reduce the address space a bit in order to assign the extra space to RAM? | |
