use grub on floppy

floppy disk

boot from floppydisk

floppy から起動させる場合

http://www.gnu.org/software/grub/grub-legacy-faq.en.html#q4 を参考

1. Create a filesystem in your floppy disk (e.g. mke2fs /dev/fd0).
2. Mount the floppy on somewhere, say, /mnt.
3. Copy the GRUB images to the directory /mnt/boot/grub. Only stage1, stage2
and menu.lst are necessary. You may not copy *stage1_5.
4. Unmount the floppy.
5. Run the following commands (note that the executable grub may reside in a
different directory in your system, for example, /usr/sbin):

/sbin/grub --batch --device-map=/dev/null <<EOF
device (fd0) /dev/fd0
root (fd0)
setup (fd0)
quit
EOF

を参考にして menu.lst は作成済とする。

This filesystem will be automatically checked every 23 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.

前準備

# rmdir /mnt/lost+found/
# mkdir /mnt/lost+found/
# mkdir -p /mnt/boot/grub
# cp /usr/local/src/grub/grub-0.97/stage1/stage1 /mnt/boot/grub/
# cp /usr/local/src/grub/grub-0.97/stage2/stage2 /mnt/boot/grub/
# mv /home/nyanco/menu.lst /mnt/boot/grub/
# umount /mnt/

/usr/local/sbin/grub

では

# shutdown -r now

できた様です。

補足

これは上手くいった例にしか過ぎません。/usr/local/sbin/grub で処理をしたということに注目しておいて下さい。

Running "install /boot/grub/stage1 (fd0) /boot/grub/stage2 p   /boot/grub/menu.lst "\

の箇所にて ”menu.lst ”が認識されています。

にゃんたろう拝！
