Last time I installed Linux on an SMP system, it detected and used both processors without a kernel rebuild. Of course, that could be a feature of the distribution I chose. BeOS does SMP in the commercial version. Solaris does SMP on Sparc; I'm not sure about x86. Windows 2K and Windows NT do SMP, Windows 9x does not. I'm not sure about Windows NT. I'd be surprised if there wasn't a table somewhere on the web listing operating systems and SMP support information. I couldn't turn it up at google, though. http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
