debian kernel & modules
Hi,
After 2 years of happily running Debian (with Windowz I needed to
reinstall every 6 months) on my Asus laptop, unforunally, I had to
reinstall my system. After reinstalling the system (sid) I found the
newest kernel running:
# uname -a
Linux h1siglushkov 2.6.15-1-486 #1 Fri Feb 10 15:40:35 UTC 2006 i686
GNU/Linux
ant A LOT of modules loded:

There are several questions about that:
1. Do I need them all?
2. How is the system deciding which modules should be installed/loaded
on bootup?
In the previous times I was compiuling the kernel by myself, I knew
exactly which modules I need and compiling them as modules (or in the
kernel). So at that time I had 10 modules as maximum loaded. But now I
see that there are no modules for some hardware, but it is working (for
example I do not see the "synaptics" module, but tapping on my pad is
working. Which modules from the above is mor the touchpad?) and from
other hand there are modules for some hardware, but it is not working
(for example ipw2200 is the module for my wireless card, but iwconfig
says that my cards do not have wireless extensions. How do I find out
which interface to which hardware is coresponding? I see eth1 (which was
my wireless card at previous times, but I am not sure that this is the
case now)).
I needed thou some additional modules to be compiled (the cpu scaling
was not working), so I decided to recompile the kernel the debian way.
I have on my system installed:
# dpkg -l | grep 486
ii linux-headers-2.6.15-1-486 2.6.15-6 Header
files for Linux kernel 2.6.15 on 486-
ii linux-image-2.6-486 2.6.15-6 Linux
kernel 2.6 image on 486-class machines
ii linux-image-2.6.15-1-486 2.6.15-6 Linux
kernel 2.6.15 image on 486-class machi
I red /usr/share/doc/kernel-package/README and
http://www.debian.org/doc/FAQ/ch-kernel.en.html, but there I do not find
where the sources for the kernel are put. I found something in /usr/src/ :
I tried:
% cd /usr/src/linux-headers-2.6.15-1-486
% make menuconfig
HOSTCC scripts/basic/fixdep
gcc: scripts/basic/fixdep.c: No such file or directory
gcc: no input files
make[1]: *** [scripts/basic/fixdep] Error 1
make: *** [scripts_basic] Error 2
% cd ../linux-headers-2.6.15-1/
% make menuconfig
Makefile:313: /usr/src/linux-headers-2.6.15-1/scripts/Kbuild.include: No
such file or directory
/bin/sh: /usr/src/linux-headers-2.6.15-1/scripts/gcc-version.sh: No such
file or directory
make: *** No rule to make target
`/usr/src/linux-headers-2.6.15-1/scripts/Kbuild.include'. Stop.
So how do I find where and what files are installed/changed using
dpkg/apt-get/aptitude for some package (in this case - the kernel package)?
Cheers,
Ivan
P.S.: Pointing me to the proper man/web page would be great..
