12/5 に見つけた mfdisk もある。
（ひ）さんを見習って usage を出してみる
# mfdisk --help
mfdisk: invalid option -- -
Partition table manipulator for BUFFALO INC. Link Station series. ver 1.5, 2003.10.3
Usage: mfdisk DISK Create partition tables for HD-LAN ver 1.xx
mfdisk -f DISK Create partition tables for HD-LAN ver 2.xx
mfdisk -h DISK Create partition tables for HD-HLAN
mfdisk -g [1:2:3:5:10:20:50] DISK Create partition tables
mfdisk -a DISK Create partition table for HD-HLAN's USB Disk
mfdisk -c DISK Create partition table(s) with menu
mfdisk -p DISK Check partition table(s)
mfdisk -e DISK Deleate all partition tables
mfdisk -d [1:2:3:4] DISK Create partition tables for Link Station
Here DISK is something like /dev/hda or /dev/sda
おー、使えそう。でも玄箱向けのパーティションはないようだ。# mfdisk -h /dev/hda delete partition 1 delete partition 2 delete partition 3 create partitions... limit = 262079 start = 63, stop(limit) = 262079 limit = 786239 start = 262080, stop(limit) = 786239 limit = 2130911 start = 786240, stop(limit) = 2130911 The partition table has been altered! Syncing disks. # mfdisk -c /dev/hda Command (m for help): p Disk /dev/hda: 16 heads, 63 sectors, 2114 cylinders Units = cylinders of 1008 * 512 bytes Device Boot Start End Blocks Id System /dev/hda1 1 260 131008+ 83 Linux /dev/hda2 261 780 262080 82 Linux swap /dev/hda3 781 2114 672336 83 Linux Command (m for help):-c をつければ、fdisk 相当である。
fdisk って、GPL だったかな？
fdisk は util-linux の一部で、玄箱の CD-ROM には、
-r--r--r-- 1 yasunari 5 1420236 Nov 26 2002 hhl-target-util-linux-2.11h-mvl2.1.0.3.src.rpmがあるので、ソースが付いている事を期待して、後日ハックしよう。
フォーマットしてみる。

ということで（？）ハックキットを玄箱にインストールする際、
別の Linux マシンも要らないし、
あらかじめ玄人志向ファームウェアをインストールしておく必要もなさそう。
と思っていたら、
