Heh, I think you need to read the handbook a bit more thouroughly. You've got three "types" of stages:

stage1
stage2
stage3

stage1 just has the tools you need to bootstrap your Gentoo system.
stage2 is already bootstrapped, you have everything you need to emerge system.
stage3 is ready to be used, you've got Instant Gentoo -- just add bootloader and kernel ;)

stage1 is "generic", that is, it's for use by the whole archietacture (x86, ppc, amd64, etc)
stage2 is compiled for different subarchs and processors. That is, they're optimized for spefic machines. You can do the same with stage1, but it's already been done for you.
stage3 is the same as stage2, except it's taken a step further. You've got nearly everything you need for a working system, immediately :)

So in other words it depends what type of installation your doing.

If you want a stage1 then grab the stage1 off a mirror (theres only one stage1: x86, you choose how you optimize your own system, if at all)
If you want stage2/3 then do the same with stage1 except choose the one for your processor. IIRC Pentium M is P4.

You could also if you got a universal livecd get the stage off the CD, do that then :)

Hope that helps,

hi, i think you need the pentium3-stages.

here i wrote i little list for you:
* 386 --> x86
* 486 --> x86
* 586, Pentium, AMD K6 Serie, Winchip-C6 -->x86
* Pentium Pro, AMD Athlon and newer ones except the following 3--> 686
* Athlon XP (and only XP) --> athlon-xp
* Pentium 3 or Pentium M --> pentium3
* Pentium 4 --> pentium4

if you dont know exactly what processor you have type in:
Code:
cat /proc/cpuinfo


regards
reto

Edit: corrected: pentium m is like a pentium 3
see this http://wiki.unixboard.de/index.php/Linux_on_Notebooks (german)

the syntax that i think you're looking for is "stage tarball." to select the correct stage tarball, you have to ask youself two questions:

1. Do I want Stage 1, Stage 2, or Stage 3?
2. What is my machine's architecture?


If you're not sure about the first answer, look here.
You can answer the second question by typing this at the bash prompt:
Code:
cat/proc/cpuinfo

Hello I'm new on gentoo and I need some help.

I have a new centrino(sonoma), and I don't know what stage3-tarball I should choose.
Some say pentium3 others say pentium4, and I dont't now what to choose.

When I'm going to compile I have an other doubt, what are the CFLAGS I should use???
can I use -march=pentium-m (if that exists :roll:)

I know that p4 or other should work but I woould like to optimize my machine.

If some one could give me a help I would be greatfull.



PS: Sorry for my English :oops:

p4 optimalization will be just ok.
If you're using gcc-3.4 try --march=pentium-m. There're a thread about it...

Wrong, a pentium M is NOT a P4. -march-pentium-m is ok, but do NOT try a P4 stage file. It won't work. Use a 686 stage file.

If you are new to Linux in general and trying your first Gentoo install your goal is to go through the install process successful and boot to a command prompt. Not worring about optimizations. I would recommend choosing a Stage 3 install that as closly matches your hardware as possible. If in doubt and you have an Intel based PC use the x86 Stage 3 tar ball. Remember the idea is to go through and achive a successful install, nothing more. Once you can do that, then go back and do a second install that more closly matches your hardware.

This is what I discovered so far.

I will install a stage3. I'm have already decide about that point.

What I'm not so sure is about the tarball to be for a pentium3 or a pentium4.

And after that to choose about the CFLAGS


After some investigation I discovered that the gcc 3.4 doesn't compile some other programs so the pentium-m is out of the question.

One friend of mine is helping me with the instalation, but he has a P4, so he also doesn't know if I should choose p3 or p4.

Most of the opinions I have earded are that the pentium-M is an "upgrade" on the p3 so I should choose a stage3-pentium3.

I think the p3 is the best but I might be wrong.
If anyone know the CFLAGS I should use that would be helpfull too :D

THANKS

if you want to err on the side of safety, choose the older hardware tarball. as an extreme example of this, you can compile for pentium and run it on all of the later pentium mmx, 2, 3 and 4 processors.
