Not the fault of Windows. For a 32 bit PC system with 4 GB of
RAM, up to 1 GB of RAM is 'lost' because up to 1 GB of
the address space is used for the PCI address space (i.e.
memory mapped access to peripherals[0]). It can be quite bit
less (such as 500 MB), or up to the full 1 GB - that depends
on the specific hardware.
The MMU can easily get around this. And indeed, I don't have this
problem with any other OS. Does Windows not understand PAE hardware?
