Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

There seem to be a number of new options which could apply to my processor and I've found conflicting reports on which I should be using in the 2.6.29 kernel options.
Am I MPENTIUMM or MPENTIUM4? (Also, is there a place where vendor_id, cpu family, and model are listed with their corresponding kernel processor family. Wouldn't it be cool if the kernel configurator had an option to automatically check cpuinfo and determine the best processor family?)
Here's my cpuinfo:
balder ~ $ cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 13
model name : Intel(R) Pentium(R) M processor 1.60GHz
stepping : 6
cpu MHz : 600.000
cache size : 2048 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr mce cx8 sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss tm pbe up bts est tm2
bogomips : 1198.95
clflush size : 64
If you have the command "lshw" installed you can use it as root to gain more detailed information about your CPU. Both Intel and Wikipedia have information on Intel CPUs by name and FSB, cache size, etc. to confirm and crosscheck by specifications.
From what you have posted, I judge the CPU to be this one.
I thought that if you could identify this as a Pentium M725, if that is what it is, and check with Intel for more information and documentation, you would have what you needed to choose options in the kernel.
The kernel may not differentiate by family and model, but does it do so by any information you can find, particularly if you could find the full specifications from Intel?
Does the kernel request information where the request is not relevant for your particular processor, where the kernel would better treat this processor at a more general level, as one of a group of similar processors, but has a request for a level of detail relevant to the others, asking perhaps for information about options that apply for some but not all Pentium processor.
I treated this as a hardware inquiry, but you might ask to have it moved to Linux-Kernel in the Software forum.
Have you tried pursuing the matter in documentation for the kernel and the kernel development project?
We may be at cross purposes here; I have no experience with the kernel but I can read a specification.

At the bottom of the Forum Hardware opening page are links to the moderators active at the time. You might use that link to write a note asking about switching your thread. Maybe it would get more traffic and thereby more responses in Newbie, although you need qualified insight more a quantity of replies.
