HDD boot 再チャレンジ

OS が HDD からブートし始めたので、もう一度インストール環境の HDD ブートをやってみる。

退避

KUROBOX-TERA:~# cd /boot
KUROBOX-TERA:/boot# ls
initrd.buffalo  lost+found  uImage.buffalo
KUROBOX-TERA:/boot# mv initrd.buffalo initrd.buffalo.orig
KUROBOX-TERA:/boot# mv uImage.buffalo uImage.buffalo.orig
KUROBOX-TERA:/boot#

ファームウェアを置く

CD-ROM に収められている initrd.buffalo uImage.buffalo を /boot に置く。

ftp で get しようとしたら、、、

KUROBOX-TERA:/boot# ftp fs.yamasita.jp
-bash: ftp: command not found
KUROBOX-TERA:/boot#

仕方がないので、インストール

KUROBOX-TERA:/boot# apt-get install ftp

一緒。

リブート

念のため、リブートしてみた。
U-Boot はちゃんと initrd.buffalo, uImage.buffalo を読み込んで立ち上がってきた。
問題なし。

何で Hdd Boot できひんかったの？

HS-DHGL でもう一度

HS-DHGL でパーティションをきったり、フォーマットした HDD からは起動しない？

再現してみる。

つなぎ換え

KURO-NAS からはずして HS-DHGL に USB で接続

確認

HS-DHGL で中身の確認

退避しておく

hackkit:~# umount /tmp/boot/

パーティションのきりなおし。ひとつだけにする

hackkit:~# fdisk /dev/sdb

The number of cylinders for this disk is set to 24792.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

結論

HS-DHGL（など他のマシン？）でフォーマットした HDD からは HDD ブートできない（ようだ）。
