NAME

     mcd -- Mitsumi CD-ROM driver

SYNOPSIS

     device mcd

     In /boot/device.hints:
     hint.mcd.0.at="isa"
     hint.mcd.0.port="0x300"
     hint.mcd.0.irq="10"

DESCRIPTION

     The mcd driver provides a data and audio interface to the Mitsumi-brand CD-ROM player.  The CD-ROM player must be interfaced to the ISA bus
     through one of the Mitsumi proprietary controller boards.	The controller boards supported are the LU002S, LU005S, the FX001 and the quite
     common FX001D.

     The mcd driver responds to disk-specific ioctl() commands, namely the DIOCGPART command.  Other disk-specific ioctl() commands will return an
     error.

     The mcd driver also responds to special CD-ROM ioctl() commands.  These commands control the CD-ROM player's audio features.  The commands
     are:

	   CDIOCREADSUBCHANNEL	get sub-channel information on current status of disc playing
	   CDIOCREADTOCHEADER	get table of contents header
	   CDIOCREADTOCENTRYS	gets all of the table of contents
	   CDIOCPLAYTRACKS	begins audio playing at location specified
	   CDIOCPLAYBLOCKS	fails with error EINVAL
	   CDIOCPLAYMSF 	begins audio playing at location specified
	   CDIOCRESUME		resumes playing a previously paused disc
	   CDIOCPAUSE		pauses a playing disc
	   CDIOCSTART		begins playing a disc
	   CDIOCSTOP		stops a previously playing disc
	   CDIOCEJECT		opens the disc tray (there is no support for a corresponding un-eject command).
	   CDIOCRESET		stops any play and resets the Mitsumi controller board
	   CDIOCSETDEBUG	cause the kernel to print debug messages to the console about the mcd driver
	   CDIOCCLRDEBUG	cause the kernel to quit printing debug messages about the mcd driver

     The ioctl() commands defined above are the only ones that the mcd driver supports.  There are other CD-ROM related ioctl() commands (such as
     CDIOCSETVOL and CDIOCSETSTERIO) which are available and may be supported by future versions of the driver.

FILES

     /dev/(r)mcd0a  accesses BSD partition on the disc.  Normally, there is only one file system on a CD-ROM disc.
     /dev/(r)mcd0c  accesses raw device.

NOTES

     The character-mode devices for the mcd driver should only be used for accessing the audio features of the CD-ROM player as the performance on
     data is abysmal.

     The current version of the driver uses neither the DMA or IRQ features of the interface board, although it has an interrupt handler for any
     IRQ requests that are generated.  Until the DMA features are supported, the only interrupts that the board generates are those that are not
     supported by the driver anyway.

HISTORY

     An mcd driver appeared in FreeBSD 1.0.

AUTHORS

     The driver was written by Holger Veit (data part) and Brian Moore (audio part).  Changes were provided by Gary Clark II, Andrew A. Chernov,
     and Jordan K. Hubbard.

Name
mcd - change MSDOS directory

Note of warning
This manpage has been automatically generated from mtools's texinfo documentation, and may not be entirely accurate or complete. See the
end of this man page for details.

Description
The mcd command is used to change the mtools working directory on the MS-DOS disk. It uses the following syntax:

mcd [msdosdirectory]

Without arguments, mcd reports the current device and working directory. Otherwise, mcd changes the current device and current working
directory relative to an MS-DOS file system.

The environmental variable MCWD may be used to locate the file where the device and current working directory information is stored. The
default is `$HOME/.mcwd'. Information in this file is ignored if the file is more than 6 hours old.

Mcd returns 0 on success or 1 on failure.

Unlike MS-DOS versions of CD, mcd can be used to change to another device. It may be wise to remove old `.mcwd' files at logout.

Viewing the texi doc
This manpage has been automatically generated from mtools's texinfo documentation. However, this process is only approximative, and some
items, such as crossreferences, footnotes and indices are lost in this translation process. Indeed, these items have no appropriate repre-
sentation in the manpage format. Moreover, not all information has been translated into the manpage version. Thus I strongly advise you
to use the original texinfo doc. See the end of this manpage for instructions how to view the texinfo doc.

* To generate a printable copy from the texinfo doc, run the following commands:

./configure; make dvi; dvips mtools.dvi

* To generate a html copy, run:

./configure; make html

A premade html can be found at `http://www.gnu.org/software/mtools/manual/mtools.html'

* To generate an info copy (browsable using emacs' info mode), run:

./configure; make info

The texinfo doc looks most pretty when printed or as html. Indeed, in the info version certain examples are difficult to read due to the
quoting conventions used in info.
