You right, devices like graphic card, ethernet cards etc. are mapped
into memory, what cause some amount RAM is not available for system use.
But as i've wrote before, i'm wondering why addresses in /proc/iomem
(where the map of memory is) are not contiguous. I think, there should
be info about what region of memory is mapped where (BIOS, PCI bus, for
system use etc)*for whole 4GB *(Am I right??) address space (for 32bit
OS). Instead of that, there are small "holes" in addresses and the total
size of this holes (in my case) is about 400MB. So i wonder where that
memory is.
