NAME

cdrom − CD-ROM disk interface

SYNOPSIS

­bind -a #Rn /dev
 /dev/cdn
 ­bind -a #m /dev
 ­/dev/cd
­/dev/cdctl

DESCRIPTION

The SCSI CD-ROM disk interface (#R) serves a one-level directory for a SCSI target holding a CD-ROM drive.  Each drive is represented as a single file named #Rn/cdn, where ­n is the target number.  A separate attach is necessary for each drive. 

On PCs, Panasonic, Matsushita, and Mitsumi CD-ROM drives connected to a Sound Blaster 16, Pro, MCD, or ACX card are also supported.  This interface (#m) device serves a data file, #m/cd, and a control file, #m/cdctl.  The control file is read-only and contains a string stating the type of drive and its port number.  The driver determines the type of CD-ROM drive by a parameter in plan9.ini; see plan9.ini(8).
