Привет
есть ПК, установлен ALS4,
мать... какой-то двух-ядреный слотовый АСУС. кажется p2b
установлено два камня, слотовые так сказать...
ну и потребовалось поставить 4 момеда, на pci
смотрю, глюки... нет двух момедов...
осмотр dmesg показал, что два устройства не смогли быть зарегистрированы
Вапрос -
1) как поймать два потеряных устройства
2) как разлулить именования устройств?
сейчас имена ttyS0&ttyS3 принадлежат pci-модемам, а ttyS1&ttyS2 - com1&com2.
насколько я понимаю -
ttyS0 - com1
ttyS1 - com2
а у меня как-то не так...
я хочу еше 2 внешних модема поставить... на эти ком-порты...
3) в dmesg -ругань на "irqpool"...
параметр к ядру в lilo.conf:
append="irqpool"
был ли я прав указав такое? что должно быть?
