Hi, I've succesfully confirmed (I think!) that my new server is a Sempron64, but it's my first time
with one of these CPUs. I'm planning to setup a courier-mta mail server.

Could you please help me to decide on stage and cflags to use? I was planning on these CFLAGS, but I
believe the stage3 should be amd64 isntead of i686 (yeah, sounds stupid, but I really want to be
sure, as this server is on a different country).

CFLAGS="-march=athlon-xp -O2 -pipe -fomit-frame-pointer -mmmx -msse -msse2 -msse3"

Of ocurse, I have to change the -march parameter to something else, for example:

http://gentoo-wiki.com/Safe_Cflags#Sempron.2FSempron64_.28AMD.29

CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=athlon64 -msse3 -O2 -pipe"
CXXFLAGS="${CFLAGS}"

Should I add -mmmx, -msse, -msse2 too?

Which stage3 should I use?

Any other recommendation, comment, or url you can point me to?

Sorry to bother you people with these, but I'm not a hardware guy, and my googling is starting to
confuse me. Sorry, but thanks in advance.

OK, replying to myself: I have to use stage3-amd64, because the other 64 bit stage3 is for IA64, and
that's Intel. Plain simple. Additionally, I have double checked that my cpu is 64 bit because the
"lm" flag is in cpuinfo, along with sse3 and nx. That, plus the lspci "k8" output, defines my CPU as
Sempron 64 (AMD64).

Thanks.
