CD-ROM -- Overview COHERENT support for read-only compact disk devices The term CD-ROM stands for ``compact disk -- read-only memory''. COHERENT supports a variety of CD-ROM devices, from which you can read files or play music. Devices Supported As of this writing, COHERENT supports three varieties of CD-ROM drives: -> Sony CD-ROM models CDU31A or CDU33A, plugged its own dedicated controller. -> Mitsumi CD-ROM models FX001, FX001 high speed, FX001D, or LU005, plugged into its own dedicated controller. Mitsumi model FX001 also is known to work when plugged into the CD-ROM port of the SoundblasterPro sound card; the other Mitsumi drives have not yet been tested with the Soundblaster Pro card. -> Any SCSI CD-ROM drive plugged into an Adaptec 1542 SCSI controller. -> Any SCSI CD-ROM drive plugged Seagate host adapter models ST01 or ST02. Please note that the NEC SCSI CD-ROM is support for ISO file systems, but not for audio disks. That is because the NEC drive does not use a standard interface for audio disks. To use the driver for the Sony CDU31A drive, you must build a kernel that contains the driver cdu31. Normally, this is done when you install or update COHERENT. To add the driver to the kernel after installation or updating, do the following: -> Log in as the superuser root. -> cd to directory /etc/conf. -> Execute script cdu31/mkdev. This script will walk you through the process of adding the driver to the kernel. If you are unsure of the answer to any question that the script asks you, select the default; in most instances, this is correct. -> Execute the command: /etc/conf/bin/idmkcoh -o coh.test This builds a new kernel called coh.test. -> Boot the new kernel, as described in the Lexicon entry booting. To use the driver for the Mitsumi drive, you must build a kernel that contains the driver mcd. Normally, this is done when you install or update COHERENT. To add the driver to the kernel after installation or updating, do the following: -> Log in as the superuser root. -> cd to directory /etc/conf. -> Execute script mcd/mkdev. This script will walk you through the process of adding the driver to the kernel. If you are unsure of the answer to any question that the script asks you, select the default; in most instances, this is correct. -> Execute the command: /etc/conf/bin/idmkcoh -o coh.test This builds a new kernel called coh.test. -> Boot the new kernel, as described in the Lexicon entry booting. If your CD-ROM drive is attached to an Adaptec 1542 SCSI controller, you must modify the driver hai to support the drive. Do so as follows: -> Log in as the superuser root. -> cd to directory /etc/conf. -> Execute script hai/mkdev. This script will walk you through the process of configuring hai to support your SCSI devices. If you are already using hai to support a SCSI disk or SCSI tape, be sure that you do not alter how they are configured. If you are unsure of the answer to any question that the script asks you, select the default; in most instances, this is correct. -> Execute the command: /etc/conf/bin/idmkcoh -o coh.test This builds a new kernel called coh.test. -> Boot the new kernel, as described in the Lexicon entry booting. Reading a CD-ROM COHERENT at present includes three commands for manipulating CD-ROMs: cdview, cdv, and cdplayer. cdplayer lets you play audio CDs on your CD-ROM drive. It uses a text- based interface to let you display the contents of a CD, select a track, set the volume, and otherwise manipulate your audio CDs. cdv is a script with which you can play CD-ROM disks -- that is, disks that hold an ISO-9660 file system. The interface is character-based and rather crude; however, with it you can read the contents of a directory on a CD- ROM, or copy a file from the CD-ROM into a COHERENT directory. cdview is a lower-level command that is invoked through cdv. Files /dev/cdrom -- Device applications read by default for CD-ROMs /dev/rscd0 -- Device for accessing Sony CDU31A CD-ROM /dev/rmcd0 -- Device for accessing Mitsumi CD-ROM /dev/Scdrom* -- Block-special SCSI CD-ROM devices /dev/rScdrom* -- Character-special SCSI CD-ROM devices See Also Administering COHERENT, cdplayer, cdrom.h, cdv, cdview, device drivers, hai, mcd Notes At present, you cannot mount an ISO-9660 file system onto your COHERENT system. A future release of COHERENT will permit you to do so. Please note that COHERENT, like most UUCP-like operating systems, does not support playing audio CDs on a NEC/Toshiba CD-ROM. This is because NEC uses a non-standard interface for audio CDs.
