The i386 architecture is incapable of addressing more than 4GB at once (since it's fundamentally 32-bit). So you have to use a hack called PAE to allow the kernel to juggle between 4GB subsets of a larger amount of RAM (up to 64GB on FreeBSD). See the handbook for documentation of PAE and its limitations. If you really need to make efficient use of such a large amount of RAM, consider purchasing an amd64-compatible system instead. Kris
