In the "Guide System Configuration File Maintenance" from the V3.0 docset, page 1-6: "physmem 'number' This paramter defines an estimate of the amount of physical memory currently in the system in Mbytes. The 'number' argument is not used to limit the amount of memory, rather, it is used by the system to size the system page table, so it should be greater than or equal to the amount of physical memory in the system." If you look in the include file /sys/machine/vmparam.h you'll see how what it is used to calculate and from there can track down that constant is used. > Thanks in advance, You're welcome. > Johan. > > Please e-mail me directly, if possible.
