FreeBSD Support for AMD64 On the Way
BSD Forums writes "FreeBSD operating system is making progress towards support for several 64bit platforms. FreeBSD 5.0 introduced SPARC64 and IA64 (Itanium) to its list of platforms and AMD64 is likely to be added in version 5.2."
All of the brouhaha over Linux seems to have overshadowed the fact that it was actually NetBSD that was the first UNIX-like operating system to boot on the AMD64 architecture (under simulation, several years ago, long before there was silicon). If FreeBSD and OpenBSD leverage this work, they won't be far behind. (OpenBSD has diverged from NetBSD, but not so much that they can't bring in the architecture-dependent stuff from NetBSD very quickly if they want to.)
