Is there info about this somewhere? Look at /boot/defaults/loader.conf, that ought to give you a good idea of what needs to be (or can be) set via that. Otherwise, try using sysctl to change things, and if they are marked read-only, then they needed to be changed earlier or by rebuilding the kernel with a different config. -- -Chuck
