regardless of how many docs i read, i'm still a bit unclear on some of the basics of memory management and "zones", so i'm going to try to clear some of that up a question or two at a time. first, as i read it, the x86 defines three "zones": ZONE_DMA <16M ZONE_NORMAL 16M-896M ZONE_HIGHMEM >896M first, are those (physical) partition addresses absolutely *fixed*, regardless of the amount of RAM on the system? that is, even if i had a system with only 512M of RAM, *technically*, ZONE_HIGHMEM is still defined as the memory above 896M, even though there is no such memory? in that case, all of RAM above 16M on my system would be considered "normal", and i would have *no* "high" memory. is that correct? rday -- ======================================================================== Robert P.
