dmesg Ritmix RZX-50

Изображение используется исключительно в целях иллюстрации и не имеет отношения к реальному «железу»

Продолжаем срывать покровы с Ritmix RZX-50, ранее известной, как R480.

Сегодня результаты деятельности вот этого скрипта:

#!/bin/sh
dmesg > dmesg.out

Скрипт вызывает стандартную юниксовую команду dmesg, которая, в свою очередь выводит лог запуска ядра. Итак, что видно:

  • ОЗУ 64МБ
  • Частота 432 Mhz
  • Ядро 2.6.24
Остальное — под катом.
Для желающих — в комментариях можно писать свои примеры скриптов, которые «выцарапают» инфу с консоли. При подключении она работает, как USB-flash,  так что фокус с телнетом пока не удался.
