I have been running FreeBSD 4-STABLE and higher on SMP boxes reliable. Those were 2 CPU boxen. For more CPU's see LINT's options: # Mandatory: options SMP # Symmetric MultiProcessor Kernel options APIC_IO # Symmetric (APIC) I/O # Optional, these are the defaults plus 1: options NCPU=5 # number of CPUs options NBUS=5 # number of busses options NAPIC=2 # number of IO APICs options NINTR=25 # number of INTs 4 Gigabyte is currently the limit. Peter Wemm [peter@freebsd.org] is current working on getting 8 Gigabyte supported and working. -- Jeroen Ruigrok van der Werven Network- and systemadministrator VIA Net.Works The Netherlands BSD: Technical excellence at its best http://www.via-net-works.nl Grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom to know the difference...
