A while back I did a big Google session to try and find the best kernel and make flags for the AthlonXP proc (under FreeBSD 4.x). At the time, most of what I read said that the AthlonXP did best with (make.conf) CPUTYPE=i686, and the k7 flag just fell back to something like that anyway because there wasn't complete support for it yet in the compiler. Likewise my kernel is set to: cpu I686_CPU Is this advice still valid, if it ever was? Can anyone comment on the best make & kernel options for the AthlonXP CPU? -- matt@wrongcrowd.com
