From FAQ for FreeBSD 4.X, 5.X, and 6.X: 4.2.2. Does FreeBSD support Symmetric Multiprocessing (SMP)? Yes. SMP was enabled by default in the GENERIC kernel as of FreeBSD 5.2. The intention was also to enable it by default for the FreeBSD 5.3 release, but problems running the SMP kernel on certain UP machines led to the decision to disable it until those problems can be addressed. This is a priority for FreeBSD 5.4.' (http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/compatibility-processors.html) From FreeBSD/i386 6.2-RELEASE Hardware Notes, "2 Supported Processors and Motherboards": Almost all i386-compatible processors with a floating point unit are supported. All Intel processors beginning with the 80486 are supported, including the 80486, Pentium, Pentium Pro, Pentium II, Pentium III, Pentium 4, and variants thereof, such as the Xeon and Celeron processors. ... Symmetric multi-processor (SMP) systems are generally supported by FreeBSD, although in some cases, BIOS or motherboard bugs may generate some problems. Perusal of the archives of the FreeBSD symmetric multiprocessing mailing list may yield some clues. (http://www.freebsd.org/releases/6.2R/hardware-i386.html#PROC)
