インストール

解像度を1024x600にする

wget http://gma500re.altervista.org/scripts/poulsbo.sh && sh ./poulsbo.sh 

タッチパネルを使えるようにする

1. 解像度を1024x600にしてから作業に入ります。
2. GalaxTouchDriver から該当するファイル(自分の場合は2.06.2905)をダウンロードします。
3. 展開して setup.sh を実行し、途中の選択肢は［2］PS/2 を選びます。
4. /etc/init.d/rc.local の case “$1” inの前に echo -n serio_raw > /sys/bus/serio/devices/serio4/drvctl と付け加えます。
5. 再起動後、eGalaxTouchを起動して、Toolタブから４点キャリブレーションで調整して設定終了です。

音を出す

alias snd-card-0 index=0
options snd-hda-intel model=basic

無線LANを使えるようにする

1. firmwareをダウンロードしてきます。
2. 展開してFwImageの中にある、helper_sd.bin を sd8686_helper.bin に名前を変えます。
3. sd8686_helper.bin と sd8686.bin を /lib/firmware にコピーします。
