The OpenSolaris source only supports a 64-bit sparc kernel - support for running a 32-bit kernel on sparc was ripped out a while back. You can, of course, still run 32-bit and 64-bit apps on top of the 64-bit kernel. > - AMD Opteron run 64bit kernel Can boot either 32-bit or 64-bit kernel > - Intel Xeon run 64bit kernel It depends on which Xeon model you have in mind ... see below. > > but what about: > > - AMD Athlon 64 X2 Dual-Core > - AMD Athlon™ 64 Yes, can boot 64-bit. The Opteron and Athlon 64 and Turion 64 families are all built around the same processor architecture - they're realy just packaging and additional frills for the particular market segment they're aimed at (server and high-end desktop for Opteron; home desktop for Athlon 64; mobile for Turion 64). > - intel Pentium 4 Newer Pentium 4 generations; not the older ones. > - intel Core 2 Due Yes. Download the "Intel 64 and IA-32 Architectures Software Developer's Manual" volume 1, order number 253665-023US of May 2007 from the intel website. Chapter 1 has section 1.1 which discusses the Intel 64 and IA-32 processors described by the manual; those that support the "Intel 64" architecture can run OpenSolaris distributions both 32- and 64-bit. The naming is not at all confusing, but section 1.1 gives a nice summary of which recent processors are IA-32 and which support Intel 64.
