The last time I touched an AMD based system was in the socket 7 days. HELP!, what do I do with the extra 32-bits of CPU goodness? :-) $200 bucks got me a Athlon 64 3000+ Venice and a ASUS A8V Motherboard. I'll be converting my Pentium 4 2.26GHz desktop system that has FreeBSD 6.1-PRERELEASE i386 on it, gcc is currently set to build with -march=3Dpentium2 and -mtune=3Dpentium4 via make.conf * How do I buildworld to amd64, and should I? * What are the best gcc -mtune / -march flags to use? * What do all the other -m flags do? * What -march flags won't run on the AMD platform, will CPUTYPE=3Dp2 work o= n AMD? * Can I still build packages for other i386 (non 64-bit) systems? * Where can I find more info about FreeBSD on AMD? * What did I forget to add here? Thanks guys. -- BSD Podcasts @ http://bsdtalk.blogspot.com/
