sillicon graphics octane2を触ってみたよ（ディスプレイコネクタ、IRIXメディア、HDD入手）

13W3→RGB15変換コネクタとIRIXのインストールメディア、HDDを入手したので、ネットワークインストールでIRIXが動くか試してみた。

ここら辺あたりを参考にしてFreeBSDマシンをサーバにしネットワークインストールをこころみた：

fx.64をロードしてrootとswapパーティーションを作成する段階は無事終了。
次はsash.64をロードしてここからminirootをロードしrootパーティーションへディストリビューションを展開する作業になるはずなんだが、なんか途中で黙りを決め込む。
以下はそのときのスクリーンショット：

起動画面。なんかエラーでる。

メニュー画面。Install System Softwareを選ぶ。

Remote Directoryを選ぶ。

サーバのIPアドレスを入力。

ディレクトリを入力。

入力が受付られて、インストールが開始する。

minirootがインストール失敗してんよ、どぉする？とかぬかしやがるから、取り敢えずrを押してみた。
何度か試しているうちにこれが出るようになったが、最初は表示が違ったような気がする。
現状がどうなっているのかちっとも分からないので、何で違いが出ているのか不明。

なんかここで止まる。Why？

この時、サーバ側のtftpdのログ（/var/log/xferlog）を見ていると、unix.IP30をロードしようとしている事が分かっている：
Apr 8 17:31:45 mouton tftpd[41026]: 192.168.3.2: read request for //inst/dist/sa: success
Apr 8 17:31:47 mouton tftpd[41028]: 192.168.3.2: read request for //inst/dist/sa: success
Apr 8 17:31:50 mouton tftpd[41030]: 192.168.3.2: read request for //inst/dist/sa: success
Apr 8 17:32:11 mouton tftpd[41032]: 192.168.3.2: read request for //inst/dist/sa: success
Apr 8 17:32:29 mouton tftpd[41034]: 192.168.3.2: read request for //inst/dist/miniroot/unix.IP30: success
Apr 8 17:32:31 mouton tftpd[41036]: 192.168.3.2: read request for //inst/dist/miniroot/unix.IP30: success

最初のsaはsash.64を読みに行ったのと、minirootのreload時に読みに行った時のもの。
rshdも設定したつもりだが、ログには特に何も出てない。

う〜ん、、さっぱりどういう状況なのか分からない。
インストールプログラムにデバッグモードとかverboseモードとか有れば良かったんだが、そんなの見あたらない。
パケットダンプして見るかなぁ、、いやしかしそれよりCD-ROMドライブ買ってきた方がはやいんじゃ、、などと思案中。

なお、Linuxが起動してこないのはディスプレイを繋いでも同じだった。
どっかで沈黙を決め込んじゃってる。
一度起動したのは何だったの？幻？

以下、Linuxが一度だけ起動したときのログ。
なぜ再現出来ない・・・・
