Why would someone want to compile a new kernel? It is often not
necessary since the default kernel shipped with Debian handles most
configurations. Also, Debian often offers several alternative kernels.
So you may want to check first if there is an alternative kernel image
package that better corresponds to your hardware. However, it can be
useful to compile a new kernel in order to:

To compile a kernel the Debian way, you need some packages:
<classname>fakeroot</classname>, <classname>kernel-package</classname>,
<classname>linux-source-2.6</classname>
and a few others which are probably already installed (see
<filename>/usr/share/doc/kernel-package/README.gz</filename> for the
complete list).

This method will make a .deb of your kernel source, and, if you have
non-standard modules, make a synchronized dependent .deb of those
too. It's a better way to manage kernel images;
<filename>/boot</filename> will hold the kernel, the System.map, and a
log of the active config file for the build.

Note that you don't <emphasis>have</emphasis> to compile your kernel

yet still use the <classname>kernel-package</classname> compilation method.

Now, you can configure your kernel.  Run <userinput>make
xconfig</userinput> if X11 is installed, configured and being run; run
<userinput>make menuconfig</userinput> otherwise (you'll need
<classname>libncurses5-dev</classname> installed). Take the time to read
the online help and choose carefully. When in doubt, it is typically
better to include the device driver (the software which manages
hardware peripherals, such as Ethernet cards, SCSI controllers, and so
on) you are unsure about.  Be careful: other options, not related to a
specific hardware, should be left at the default value if you do not
understand them.  Do not forget to select <quote>Kernel module loader</quote>
in <quote>Loadable module support</quote> (it is not selected by default).
If not included, your Debian installation will experience problems.

Once the compilation is complete, you can install your custom kernel
like any package.  As root, do 
<userinput>dpkg -i
../linux-image-&kernelversion;-<replaceable>subarchitecture</replaceable>_custom.1.0_&architecture;.deb</userinput>.
The <replaceable>subarchitecture</replaceable> part is an optional
sub-architecture,
<phrase arch="i386"> such as <quote>686</quote>, </phrase>
depending on what kernel options you set.
<userinput>dpkg -i</userinput> will install the
kernel, along with some other nice supporting files.  For instance,
the <filename>System.map</filename> will be properly installed
(helpful for debugging kernel problems), and
<filename>/boot/config-&kernelversion;</filename> will be installed,
containing your current configuration set.  Your new
kernel package is also clever enough to automatically update your boot
loader to use the new kernel. If you have created a modules package,
you'll need to install that package as well.
