    NAME

    
    
    atapicam
    
     - CAM XPT (transport) module for ATAPI devices
    
     
    

    SYNOPSIS

    device atapicam  

    DESCRIPTION

    The ATAPI/CAM module allows ATAPI devices (CD-ROM, CD-RW, DVD drives, floppy drives such as Iomega Zip, tape drives) to be accessed through the SCSI subsystem, cam(4).

    ata(4) and scbus(4) must be configured in the kernel as well. The SCSI target drivers (cd4, da(4), or st(4)) can then be used to access the devices. The generic passthrough device, pass(4), can also be used to send SCSI commands directly to the devices through the CAM API.

    A separate CAM bus is created for each ATA bus in the system. On each of these buses, target ID 0 is assigned to the master device, and ID 1 is assigned to the slave (provided they are ATAPI devices).  

    IMPLEMENTATION NOTES

    Some SCSI commands are intercepted by the driver, and undergo special processing in order to work around limitations of ATAPI devices. Such limitations can be consequences of the ATAPI specification. For example, ATAPI devices do not implement the 6-byte versions of MODE_SELECT , MODE_SENSE , READ or WRITE They can also be common bugs, such as hanging when queried for extended INQUIRY information.  

    EXAMPLES

    device ata
    device atapicam
    device scbus
    device cd
    device pass
    

    Add the driver to the kernel.

    "camcontrol devlist"

    Print the list of all devices available through CAM.

    "mount -t cd9660 /dev/cd0 /mnt"

    Mount a CD-ROM from an ATAPI CD-ROM drive (the command above assumes that the ATAPI drive is the only CD-ROM unit).

    HISTORY

    The ATAPI/CAM driver first appeared in Fx 4.8 and Fx 5.0 .  

    AUTHORS

    The ATAPI/CAM driver was written by An Thomas Quinot Aq [email protected] .  

    BUGS

    and ATAPI-specific target drivers (acd4, ast(4), and afd(4)) can be configured in the same kernel. Simultaneous access to the same device through the SCSI generic drivers and the ATAPI-specific drivers may cause problems and is strongly discouraged.
