netboot

- Netbooting IBM pSeries & RS/6000

(実は、これは多分全然役に立たない)
http://penguinppc.org/~hollisb/linux/rs6k-netboot.shtml
- (bootps)
bootps を使って MAC address -> から IP Address 等の設定を得る
- (tftp)
ofwboot という名前の Open FirmWare boot 用プログラム (ELF 形式)を tftp で転送する
- (ofwboot)
前項で転送した ofwboot が起動し、
rp で指定された Path を NFS mount して netbsd.ofppc を読む
- (kernel)
その読んだ
netbsd.ofppc という名前の kernel が起動し もう一度 root path を mount する
- (mount fs)
/etc/fstab を読み 必要な filesystem を mount する
- /sbin/init を起動する
server
20060807/sys/arch/ofppc/stand/ofwboot/obj/ofwboot
を使う。/tftpboot に写しておく。

/etc/inetd.conf
tftpboot と bootps の行を生かしておく
ここまでの段階で、tftp と nfs が利用出来るか調べておく。
