標準ファーム入り HDD の作成

LS-LGL
LS-LGL の標準ファーム入り HDD を１から作ってみる。
作れることがわかれば、購入時についてきた HDD を壊しても怖くない。

使用する HDD

Seagete の 10GB IDE HDD ST310212 を使用する。

LS-GL に接続

ST310212 を USB でハックキット化した LS-GL に接続する。

sdb と認識する。

LS-GL か HS-DHGL で使った形跡がある。 

ude:~# mkdir /tmp/root
ude:~# mount /dev/sdb2 /tmp/root
ude:~# cat /tmp/root/etc/linkstation_release
VERSION=1.02
SUBVERSION=HDD 1.23
PRODUCTID=0x0000000A
BUILDDATE=2006/11/27 19:13:04
ude:~# umount /tmp/root
ude:~#
PRODUCTID=0x0000000A なので、HS-DHGL。

パーティションの削除

このパーティションをこのまま使っても良いが、 後からの再現が楽なように、パーティションを完全に削除する。 
ude:~# fdisk /dev/sdb

The number of cylinders for this disk is set to 9768.
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)
