► Memory Remap Feature
This item is used to enable/disable memory remapping around memory hole.
PCI doesn't actually care much which addresses are used, but by convention the PC platform
puts them at the top of the 32-bit address space. For many years it wasn't possible or practical to
put that much RAM into a PC. But now it is, so it's up to the memory controller and host bridge to
figure out what to do. Many systems cause that high RAM to simply be ignored, resulting in the
loss of effective RAM. More complex systems will take the RAM that would occupy that 3.5-4GB
address space and re-map it into the 4.0-4.5GB address space. The RAM doesn't care because
it's just an array of storage cells, it's up to the memory controller to associate addresses with
those storage cells. Of course, that only works if you're using a 64-bit (or 32bit physical address
extension (PAE) enabled) OS that can deal with physical addresses larger than 32 bits. Once
this option is enabled, BIOS will display the true size of memory installed.
