You are using FreeBSD 4, which use a gcc-version (2.95?) that does not optimise for athlon cpus. 'k7' are therefore translated to 'k6'. FreeBSD 5 use a different gcc (3.2-something) that optimise for newer cpu's including various athlon variants. i686 in the kernelconf is correct for durons. Cheers, Are-Harald
