ブートに関して

デフォルトのブートローダではkernelリージョンに1.4Mbytes程度しか書き込めません。ramdiskリージョンをつぶしてkernelリージョンにしたブートローダに差し替えることで大きなサイズのkernelを使うことができます。

ブートローダのソース

• ftp://ftp.nagoya.bug.gr.jp/pub/hamajima/armadillo210/loader-armadillo210.tar.gz

ブートローダのバイナリ

• ftp://ftp.nagoya.bug.gr.jp/pub/hamajima/armadillo210/loader-armadillo210.bin
• ftp://ftp.nagoya.bug.gr.jp/pub/hamajima/armadillo210/loader-armadillo210-ttyAM1.bin
• ftp://ftp.nagoya.bug.gr.jp/pub/hamajima/armadillo210/loader-armadillo210-notty.bin

こんな感じで書き込みます。

% hermit download -i loader-armadillo210.bin -r bootloader --force-locked

サンプルのkernel

• ftp://ftp.nagoya.bug.gr.jp/pub/hamajima/armadillo210/netbsd.bin.gz
  • ユーザ名はnbug、パスワードはNetBSDを使います。rootになるにはsudoを使います。

• http://www.tokuda.net/NetBSD/Armadillo210/20071031/netbsd-ARMADILLO210_TINY.bin.gz
  • 約1.4Mbytesの小さなkernelです
  • 以下のパッチおよびソースの追加を行いbuild.shを使って作成しました
