Also, >there is no such thing as ``device matcd0'' only ``controller matcd0'' Hi, Mark, My CDROM is an IDE device, not proprietry device, and CDROM type is CR-583. I follow your instructions to delete "controller matcd0" in kernel config file, then compile kernel, reboot. FreeBSD CAN detect it, but I reboot it again, FreeBSD CAN'T detect CDROM, and I try many times, still fails :( Is it FreeBSD problem or my CDROM problem, I really don't know. P.S. I set my CDROM is secondary primary.
