Yes, it is set in the kernel. Then on top of that login.conf can limit it further. I put this in /boot/loader.conf: kern.maxdsiz="2G" kern.dfldsiz="2G" #hw.physmem="2G" kern.maxssiz="128M" Notice hw.physmem is commented out. Originally added when an early (prerelease) 6.0 did not automatically recognize more than 1G. Created all sorts of problems for ACPI which went away when the line was removed, and by that time the kernel properly automatically recognized installed RAM. -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
