lol pentium 3 is not centrino!

You in fact have a pentium-m with Intel wireless. Centrino is not the name of a processor.

The pentium 3 is the next closest chip in terms of architecture / instruction-set.

More generic than pentium3, but it would work.

Nothing is broken. -march=pentium3 is the closest you are going to get with gcc 3.3 . . .

i also found this

The core of the Pentium-M cpu is closer to the Pentium 3 wrt timings,
P4 has a much longer pipeline. It does indeed have added sse2 instructions, howerver.
I use CFLAGS="-O2 -march=pentium3 -msse2 -fomit-frame-pointer -pipe"

so if i use pentium 3 and change the flags to CFLAGS="-O2 -march=pentium-m -msse2 -fomit-frame-pointer -pipe" or must be pentium3

thnx

The CHOST is i686. No surprise there. Note the -march=pentium3. This is exactly what is on the stage3's make.conf

What does surprise me is this idiot thinks -march=pentium4 would work with a pentium-m. I better fix this wiki.

pentium-m is only for gcc 3.4 and above. A lot of gentoo users (probably including you) have gcc 3.3, thus they cannot use pentium-m.

That has nothing to do with CFLAGS. speedstep support is the job of the kernel, not gcc.

which kernel must i use for this? Is 2.6.12-r10 ok or i must use development kernel.

Yes i am using gcc 3.3 so i must use pentium3 and when i will install gcc 3.4 then i can use pentium-m?
Is this correct? So if i install now gcc 3.4 i must change pentium3 to pentium-m?

thnx

Not needed.

Yes, thought my guess is this will not happen for a long long time.

Not 100% necessary. You can keep the pentium-3 setting even after upgrading to gcc 3.4.
