FreeDOSでBIOSアップデートしてみる
BIOSのupdateにDOS起動が必要とか、いまどき前時代な感じがしますよ。
でも、TX-50のBIOSをアップデートするのには、そういう環境がいるのだよね。
いまさらDOSとかないし。
いや、あるけどFDDなんてもう読めないのじゃ？
Windowsから作るのもなんだし、FreeDOSでやってみることにした。
USB FloppyDIskとかないので、こちらもUSBメモリから起動することにする。
まずは、syslinux入れる。

USBメモリか...
とりあえず32MB(！)と書いてあるのが転がっているので、これでいいか。
sdcとして認識された。
パーティションはこんなの。
# fdisk -l /dev/sdc
Disk /dev/sdc: 31 MB, 31571968 bytes

Partition 1 has different physical/logical endings:
phys=(10, 128, 41) logical=(11, 84, 41)めんどくさいのでパーティション切り直して、再フォーマットする。
ついでにMBRもクリーンに再構築。

きれいになった。

なんかいろいろアーカイブされているのねぇ。
knoppixの残骸が設定にいっぱい。

これだけでは起動できない。
チェーンローダー経由で起動するのに入れる。
# dpkg -L syslinux-common | grep chain.c32 /usr/lib/syslinux/chain.c32 # cp /usr/lib/syslinux/chain.c32 /mnt/ # vi /mnt/syslinux.cfg default freedos prompt 1 timeout 30 label freedos kernel chain.c32 append freedos=/kernel.sys
こんでどを？
よし、出来た。
起動を確認。
安全な運用のためには、autoexec.batを作ったほうがいいけど、めんどくさいからやらない。
BIOSのexeをUSBメモリにコピー。
TX-50にこのUSBメモリを挿して起動すると、USBメモリ側から起動してきた。
DOSプロンプトになる。
日付と時間入れるとか、なつかしーねー。入れないけど。
実行すると、アップデータが起動、書き換え後に自分で再起動した。
BIOS画面からは、バージョンの確認はできない。
VGAなしで起動してみた。
とりあえず、NICさしたら通信しているようなので、起動している模様。
