Some memory is lost to the gfx board. Some is blocked to make room for
PCI devices. When you only have 1GB there where 3GB space left for PCI
so nothing had to be blocked.
Usualy the parts lost to PCI should be remapped to above 4GB. But not
every chipset can do that, esspecially those limited to 4GB. Or the
option is turned of in the bios.
My POV/ION330 board supports up to 8GB ram and I configured the gfx to
use only 32MB. Still I only see 3.5GB of my 4GB ram. I'm in the same
situation of wondering where my ram did go.
