Greetings, I had just signed up for he forums to ask the same question but if the op doesn't mind I would like to ask a few additional ones. I am not trying to hijack ur post but I feel these may benefit you as well.

I'm sorry if I don't get to specific on some things as I am sending this from my phone atwork.

I am installing gentoo on an hp g60 laptop (us530 series) and have the same CPU which is dual core x64 arch.
I have chosen to use the amd64 install and was wondering when compiling the kernal should I use the core 2 option or generic.

also I would like to squeeze the maximum performance out of the machine I can get which is why I'm choosing to use gentoo n the first place to learn Linux as after giving ubuntu a tryseems like a terrible learning platform...it was easier to use than windows lol. And getting into the network admin field learning Linux at it's core is what I'm really looking for here. What flags if any are recmmended outside of the known safe:
CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=nocona -O2 -pipe"
CXXFLAGS="${CFLAGS}"

like I said I woul like it to be fast functionable and light which is why I think I'm goin to use xfce as my desktop.


I am dual booting windows 7 since I am forced to use programs for school only compatible with windows but for everything else I want to replace windows and to play some games like quake urban terror and the halflifes.
So any additional options I should be considering please let me know.

Again thanks in advance, although this is my first post I have been browsng the forums for a while and am very impressed with the scene and it's helpfulness. I'm sure I will be spending lots of time n these forums...hopefully not asking too many stupid questions.

CFLAGS="-march=native -O2 -pipe"
CXXFLAGS="${CFLAGS}"

if you're unsure whether or not your cpu will work with amd64, just check the "flags" line under /proc/cpuinfo

if you see a flag "lm", you should go amd64

My laptop uses a T4200 on amd64, so you should be fine.

Code:

# sort -u /proc/cpuinfo |grep flags.*\ lm
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good aperfmperf pni dtes64 monitor ds_cpl est tm2 ssse3 cx16 xtpr pdcm xsave lahf_lm


look right after "pbe syscall", and see "lm". If you have that, you're good to use amd64

I also have a G60 with the T4300. Is -march=native really faster than -march=nocona? :evil:
