HW reset results: CBLID- above Vih Device num = 0 determined by the jumper Checksum: correct Всё работает, но как-то медленно. Есть желание "получить больше за те же деньги". :) Файл /etc/sysconfig/harddisks сплошные комментарии. Я правильно понимаю, что в моем случае снять комментарий с включения дма вполне безопасно? И в строку дополнительных ключей можно внести установку режима pio4? Или не стоит? И нужно создавать по отдельному файлу на каждое устройство в /etc/sysconfig/harddisk? -- Rgrds, Andriy ********************************************************************* email: dobr at iop dot kiev dot ua Kyiv, Ukraine Phone: (380-44) 265-7824 Department of Gas Electronics Fax: (380-44) 265-2329 Institute of Physics of NASU *********************************************************************
