<P>
|
|
<P>Portions of this text come from comments in the kernel source
|
|
files (obviously). I have added annotations in many places.
|
|
I hope that this will be useful to kernel developers -- either
|
|
new ones or experienced ones who need more of this type of
|
|
information. However, if there's not enough detail here for
|
|
you, "Use the Source."

<H2><A NAME="ss1.1">1.1 Overview</A>
|
|
</H2>
|
|
|
|
<P>
|
|
<P>This description is organized as a brief overview which
|
|
lists the sections that are described later in more detail.
|
|
<P>The description is in three main sections. The first section covers
|
|
early kernel initialization on IA-32 (but only after your boot loader of
|
|
choice and other intermediate loaders have run; i.e., this description
|
|
does not cover loading the kernel).
|
|
This section is based on the code in "linux/arch/i386/boot/setup.S"
|
|
and "linux/arch/i386/boot/video.S".
|
|
<P>The second major section covers Linux initialization that is
|
|
x86- (or i386- or IA-32-) specific. This section is based on the source
|
|
files "linux/arch/i386/kernel/head.S" and "linux/arch/i386/kernel/setup.c".
|
|
<P>The third major section covers Linux initialization that is
|
|
architecture-independent. This section is based on the flow in the
|
|
source file "linux/init/main.c".
|
|
<P>See the References section for other valuable documents
|
|
about booting, loading, and initialization.
|
|
<P>

|
<H2><A NAME="ss1.2">1.2 This document</A>
|
|
</H2>
|
|
|
|
<P>
|
|
<P>This document describes Linux 2.4.x initialization on IA-32
|
|
(or i386 or x86) processors -- after one or more kernel boot loaders
|
|
(if any) have done their job.
|
|
<P>You can format it using the commands (for example):
|
|
<P>
|
|
<BLOCKQUOTE><CODE>
|
|
<PRE>
|
|
% sgml2txt ia32_init_240.sgml
|
|
</PRE>
|
|
</CODE></BLOCKQUOTE>
|
|
|
|
or
|
|
<BLOCKQUOTE><CODE>
|
|
<PRE>
|
|
% sgml2html ia32_init_240.sgml
|
|
</PRE>
|
|
</CODE></BLOCKQUOTE>
|
|
<P>This will produce plain ASCII or HTML files respectively.
|
|
You can also produce LaTeX, GNU, and RTF info by using the proper
|
|
sgmltool (man sgmltools).
