network install はまったので覚書
Centos network installのCDがあったのでpe750をCDより起動して
サーバーよりデータを取ってくる段階で
The CentOS installation tree in that directory does not seem to match your boot media.
と怒られて前に進まず…
http://bugs.centos.org/view.php?id=2937
でもおなじようなことが書いてあり、どうやらmd5sumが違うから動かないということなので
http://ftp2.riken.jp/Linux/centos/5/isos/i386/CentOS-5.2-i386-netinstall.iso
をダウンロードしてCDに焼き、やり直したところ無事installできた。
どうやらnetwork installのCDが5.1だったぽくだめだった模様。
CDには同じ轍を踏まないために焼いた日時とcentos 5.2とマジックで書いといた
これから5.2のinstallをしてないってことかぁ
