U-Bootで使える初代玄箱（無印）の2.6.25.20Linuxカーネルを作成する。
まずは、コンパイルに必要なプログラムをインストール。
KURO-BOX:/usr/src# aptitude install patch
KURO-BOX:/usr/src# aptitude install libncurses-dev
KURO-BOX:/usr/src# aptitude install bzip2
KURO-BOX:/usr/src# aptitude install module-init-tools
次に、ソースのダウンロードして、解凍する。
KURO-BOX:/usr/src# wget http://www.genbako.com/kurobox-sources-2.6.25.patch
KURO-BOX:/usr/src# wget http://www.genbako.com/kurobox-section-mismatch2625.patch
KURO-BOX:/usr/src# wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.25.20.tar.bz2
KURO-BOX:/usr/src# tar -jxpvf linux-2.6.25.20.tar.bz2
次に、パッチを当てる。
KURO-BOX:/usr/src# cd linux-2.6.25.20
KURO-BOX:/usr/src/linux-2.6.25.20# patch -Np1 < ../kurobox-section-mismatch2625.patch
KURO-BOX:/usr/src/linux-2.6.25.20# patch -Np1 < ../kurobox-sources-2.6.25.patch
次に、前準備を行う。
KURO-BOX:/usr/src/linux-2.6.25.20# export ARCH=ppc
KURO-BOX:/usr/src/linux-2.6.25.20# cp config_kurobox .config
KURO-BOX:/usr/src/linux-2.6.25.20# make oldconfig
ここで大事なカーネル設定を行う。

とりあえず、iptable、IPsec、マルチキャスト、IPIP/GRE トンネル、Dummy インタフェース、ブリッジング、802.1Q VLANとUSB無線LANのいくつかを有効にして設定を保存。
そしてついにコンパイル。ここでuImageを作成します。

無事にuImageが作成できたので続けて、モジュールの作成とインストール
KURO-BOX:/usr/src/linux-2.6.25.20# make modules
KURO-BOX:/usr/src/linux-2.6.25.20# make modules_install
作成しuImageを格納するために既存のものをバックアップする
KURO-BOX:/usr/src/linux-2.6.25.20# cd /boot
KURO-BOX:/boot# ls -la
drwxr-xr-x 3 root root 4096 2011-06-26 22:35 .

KURO-BOX:/boot# mv System.map System.map.org
KURO-BOX:/boot# mv uImage uImage.org
作成したuImageとコピーする。
KURO-BOX:/boot# cp -p /usr/src/linux-2.6.25.20/arch/ppc/boot/images/uImage /boot
KURO-BOX:/boot# cp -p /usr/src/linux-2.6.25.20/System.map /boot
最終的にはこんな感じ
KURO-BOX:/boot# ls -la
drwxr-xr-x 3 root root 4096 2011-06-26 22:35 .
drwxr-xr-x 21 root root 4096 2011-04-10 05:23 ..

これで、再起動後、起動確認。
