ディスクレスクライアント起動
ASRock AD2700-ITX PCをディスクレスクライアント実験機として使用するが、HDDがつながっているマシンなので、ブート画面で F11 を素早くタイプしてブートセレクタ画面を表示させ、そこで pxeboot を選択するか、BIOSのBootに関する項目で 1番目をLAN 、以降をdisable に設定すればいい。
F11 でブートセレクタを表示
BIOSで起動順位をネットワークに変更
ネットワークからのブートが成功すると以下のような画面になる。
PXEBOOTが成功した場合の画面表示
その他の起動手順も成功すれば、以下のようにブートメッセージが表示されて起動が終了する。（下記メッセージは dmesg をコピーしたもの）

以上で、ディスクレスクライアントの起動が完了。
しかし、この時点では、サーバーにインストール済みのアプリケーションを利用可能であるが、X-Windowは動いていないので、リモートからログインしてCPUパワーを使うくらいしか利用方法がない。 それでも、BOINCくらいは動かせそうなので、次回のメモではBOINCに挑戦してみる。
