I'm still not clear on the /usr/src/UPDATING entry from 20110424 on replacing the ATA drivers by CAM drivers. If I *do not* have device ata in the kernel, I have neither /dev/cd* or /dev/acd*, even though I have in the kernel: options ATA_CAM # Handle legacy controllers with CAM options ATA_STATIC_ID # Static device numbering device ada device cd # CD If I then add device ata to the kernel, then /dev/cd0 appears: cd0 at ata0 bus 0 scbus1 target 0 lun 0 cd0: Removable CD-ROM SCSI-0 device cd0: 16.700MB/s transfers (WDMA2, ATAPI 12bytes, PIO 65534bytes) cd0: cd present [248633 x 2048 byte records] Is that expected? My understanding of the above /usr/src/UPDATING entry is that device ata should not be needed. Am I wrong? # cat /etc/fstab # Device Mountpoint FStype Options Dump Pass# /dev/ada0s1b none swap sw 0 0 /dev/ada0s1a / ufs rw 1 1 /dev/cd0 /cdrom cd9660 ro,noauto 0 0 /dev/da0s1 /mnt msdosfs rw,noauto 0 0 # Many thanks -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 331 5944 Fax: +44 (0)117 929 4423
