Subject: [FreeBSD] Патч для преодаления ограничения в 32 порта в sio
>У меня уже стоит четыре восьмипортовки в тачке (Zelax MAK-82) (FreeBSD 3.5).
>Хотел вставить еще одну, но напоролся на ограничение: 32 порта в sio.
>Можно как-нибудь побороть это ограничение?
Попробуй пропатчить три файла (результат не гарантирую!!!):

For each port there is a callin device and a callout device.
! The minor number of the callout device is 128 higher
than that of the corresponding callin port.
The callin device is general purpose.
