FlashROM内部の解析
NV-XYZ777
HD2パーティション経由でFlashROM内の領域にアクセスしてみました。
今回もファイル一覧を置いておきます。
XYZ777_FlashROM.txt
これらファイルを眺めていると「Hard Hat Linux」という文字が含まれています。
この事から想像するとどうやらNV-XYZ777で使われているOSはMontaVista Linuxのようです。
ここを見るとどうやら間違いなさそうです。
あと/var/tmpにブートログがありました。
カーネルのバージョンは2.4.20。
このあたりは安定性を重視して2.4なのでしょう。
メモリは128Mbyteと思ったより少ないです。
dmesg.logを添付するので詳細は以下を見てください。

どうやってHD2経由でフラッシュにアクセスしたのでしょうか？
