Intel Chipset manual page 46 clearly shows PCI IO map moved to the top of the 64GB stack in the Intelte chipset for address space >4GB
Look at it again. It has two areas with mmio. One below 4 GB and one below 64 GB. The traditional mmio is not moved. It is still located below 4G. Look at how the ram is remapped (reclaim base).
No, and btw, if you look at the map you'll se "OS Invisible" in the overlapping area with mmio. Which means that part of the ram is not usable without remapping - and 32bit desktop Windows refuses to address the ram when remapped above 4G.Yep.
