Re: Installing new kernel on dual boot grub system

I have a Toshiba Qosmio G25 that comes with windows XP installed. I used
the newest Etch installer to load Debian onto the 2nd harddrive. This
worked reasonably well. Grep was installed in the /MBR of the first (XP)
disk. All this worked fine. Then I decided that I wanted to customize the
kernel and use the latest stable version from the Linux web site. I have
done this with LILO, on another system, many times. I have never used Grub
before.
I have read everything I can find on Grub and now am totally confused. All
the instructions are slanted towards initial installation and do not match
what is installed in my system. My /boot contains the following:
config-2.6.18-4-686
grub (directory)
initrd.img-2.6.18-4-686
System.map-2.6.18-4-686
vmlinuz-2.6.18-4-686
Questions:
1. Does the config file normally end up in this directory or do you have
to cp the .config from the /usr/src/linux-xxx directory.
AFAIK, the config-* file is only there for your reference.
2. Where did the initrd.img file come from. I couldn't find it in
/usr/src/linux-xx.
3. The System.map-xxx file has no link to a System.map file as in LILO. Is
this normal or is it that I only have one linux kernel installed.
4. If I type in grub and get grub> , what do I do to install the new
kernel and still keep the vmlinuz-2.6.18-4-686 kernel.
Building a .deb package from the kernel sources is the easiest way.
Most of the Debian instructions seem to assume that you are using a .deb
file for installation. This is something I never do for the kernel. I
always go to the Linux web site to get the latest release. Some one needs
to write a Grub HOWTO that is more informative. I would do it but obviously
don't have the necessary knowledge.
There's a debian kernel handbook at
http://kernel-handbook.alioth.debian.org/ which you should go through.
Short version: install kernel-package and use make-kpkg to build a
.deb from the pristine kernel.org sources if that's what you want.
The menu.lst changes seems to be a straight forward text editing job. Right ?
Installing the kernel from a make-kpkg created .deb will do that for
you automagically.
All help will be appreciated.
