この数年、
Trim Slice とは
Trim Sliceは、

最大の特徴はその大きさで、


スペックそのものは次のとおりで、
- Trim Sliceのインターフェース
(図4・ 図5 ) - CPU: NVIDIA Tegra2
(Cortex A9 dual core) - Memory: 1GB
- USB2.
0 x4ポート (通常サイズ) - USB2.
0 x1ポート (microUSB) - HDMI出力
- アナログステレオラインアウト
- アナログステレオラインイン
- デジタルオーディオ出力
(S/ PDIF) - SDカードスロット
- microSDカードスロット
- UARTポート
(RS-232C) - DVI出力
(オプション) - SATA
(オプション) (注3) - 11n WLAN
(オプション) - Gigabit Ethernet
[4]
- CPU: NVIDIA Tegra2


ARM Cortex A9と1GBメモリを搭載し、
ブートローダーはubootで、
購入方法
Trim Sliceは現時点では日本国内に販売代理店が存在しないため、
CompuLabから直接購入する場合は海外発送となります。筆者が購入した際はUPSによる国際便で、
モデル選択
Trim Sliceには次の5モデルが存在します。ハードウェア的には3種類で、
- Trim Slice Bareborn
- Trim Slice Value
- Trim Slice Pro
- Trim Slice H Diskless
- Trim Slice H250
BarebornとValueは最低限の機能を搭載したモデルで、
ProはBarebornに11n無線LANユニットとセカンダリモニタ出力
H DisklessとH250は、
日本国内で利用する場合、
必要な周辺機器
Trim Sliceを
- HDMIケーブル
- HDMIもしくはDVI-Dで入力可能なモニタ
- USBキーボード
- USBマウス
- イーサネットケーブル
- RS-232Cクロスケーブル
- RS-232Cポートが存在するPC
(もしくはUSB=RS-232C変換アダプタとPC) - SDHCカードを読み書きできるPC
- プラスドライバ
モデルによっては、
- SDカード
(OSインストール用) - microSDカード
(内蔵ストレージ用。SSD搭載モデルや2. 5inchHDD/ SSD搭載可能モデルでは不要) - 2.
5inch HDD/ SSD (内蔵ストレージ用。搭載可能モデルのみ)
次のものは本体に付属していますので、
- HDMI=DVI-D変換アダプタ
- ACアダプタ
- 本体の小型RC-232C出力を標準的なDB9に変換するアダプタ
特にRC-232CクロスケーブルはOSインストールや初期設定時に利用するため、
セットアップ
Trim Sliceが無事に手元に届いた後は、
セットアップの基本的な手順は、
uboot環境への接続
作業の前に、
Trim Slice側の電源を切った状態でシリアルケーブルを接続し、
この状態でTrim Sliceの電源を入れると、
ubootイメージの更新
ubootイメージの更新を行います。ubootはPC-AT機におけるBIOSに相当するベースレベルファームウェアで、
ubootの更新は簡単で、
起動から数秒でubootの書き換えが終了し、

Scanning ext2 mmc 0 on prefix / ... Loading file "/boot.scr" from mmc device 0:1 (xxa1) 727 bytes read boot.scr found! Executing ... ## Executing script at 00408000 starting boot.scr Loading file "/u-boot.slice" from mmc device 0:1 (xxa1) 296960 bytes read SF: Detected W25Q80BL with page size 256, total 1 MiB 1024 KiB W25Q80BL at 0:0 is now current device Saving Environment to SPI Flash...

インストールメディアの準備とインストール
Trim SliceへのUbuntuの導入には、
標準状態のUbuntuとの違いは、

インストール先のストレージとしては、
ubootの場合と異なり、
基本的にSDカードやmicroSDカード・



USBメモリからブートする(Bareborn/Valueモデル)
BarebornやValueモデルの場合、
Trim Sliceでは、
boot.
$ wget ftp://ftp.denx.de/pub/u-boot/u-boot-latest.tar.bz2 $ tar jxvf u-boot-latest.tar.bz2 $ cd u-boot-2011.06 $ make tools $ sudo install tools/mkimage /usr/local/bin
ツールの準備ができたら、
echo booting from external USB
setenv rootfs rw root=/dev/sdb1 nohdparm rootwait
書き換えが終わったら次のコマンドでboot.
mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Trim-Slice-Bareborn" -d ./boot.txt ./boot.scr
初期設定
Trim Sliceのインストールが終わっても、
GDMを止める
Trim SliceはHDMI経由でデスクトップ環境を利用することもできますが、
これにより、
タイムゾーンとロケールの変更
デフォルトの状態では、
また、
初期ユーザー名の変更
Trim Sliceのインストーラは、
この方法の都合上、
ユーザー名を変更する場合、
SSHの設定を修正する
インストーラーの仕様上、
次の操作を実行して、
# cd /etc/ssh # mv ssh_host_*_key* .bak # dpkg-reconfigure openssh-server # service ssh restart
また、
シリアルポートからの自動ログインを抑制する
Trim Sliceのデフォルトでは、
また、
おわりに
なにかの参考になるかもしれないので、
1~2万円程度で購入できる廉価なサーバーマシンに飽きたら
