With the default settings, usually, on any 32bit OS, including Win2k and Linux and FreeBSD, there is only 2G of virtual memory accessible for user process. The other 2G part is for kernel to use. Each OS has some knobs that you can turn to change the ratio to 3:1 or some other split. But there is always a part that is just for kernel to use, inaccessible to user process. -- VH
