.Pp
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm matcd
|
|
driver controls the CR-562-x and CR-563-x CD-ROM drives made by
|
|
Matsushita-Kotobuki Electronics Industries, or Matsushita for short.
|
|
These CD-ROM drives have been sold under the Panasonic (which is a trade
|
|
name for Matsushita), Creative Labs (omniCD) and Reveal names, and have
|
|
been included in computers made by Tandy, AST, Packard Bell and many others.
|
|
|
|
These drives connect to the PC ISA bus through a proprietary host interface.
|
|
This interface can exist as a stand-alone ISA card, or can be included on
|
|
a sound card.
|
|
|
|
.Sh DRIVER CONFIGURATION
|
|
The
|
|
.Nm matcd
|
|
driver supports up to four host interfaces with up to four drives on each
|
|
interface. Audio activity may occur on all drives simultaneously. Data
|
|
read operations are limited to one drive per host interface at any instant.
|
|
|
|
To support multiple host interfaces, it is necessary to modify the
|
|
entries in the kernel configuration file. Normally your system comes
|
|
with the file \fI/usr/src/sys/i386/conf/GENERIC\fR. You should make
|
|
a copy of this file and give it the name of your system.
|
|
You can then edit the new file to include devices you want the system
|
|
to support and delete the device entries that you don't want.
|
|
|
|
In this file, you will find an entry like:
|
|
|
|
controller matcd0 at isa? port ? bio
|
|
|
|
To support two host interfaces, change the file so it reads:
|
|
|
|
controller matcd0 at isa? port ? bio
|
|
.br
|
|
controller matcd1 at isa? port ? bio
|
|
.br
|
|
|
|
(If you want to support up to three or four host interfaces, add
|
|
additional entries).
|
|
.if n .bp
|
|
.if t .sp
|
|
Note that the kernel configuration does not need to be modified to support
|
|
up to four drives on a single host interface. It is also not necessary to
|
|
have four drives on a single interface before adding a second interface.
|
|
|
|
By default,
|
|
.Nm matcd
|
|
searches for the CD-ROM host interface adapters by using a table of known I/O
|
|
ports on Creative host adapters (see \fIoptions.h\fR). Although this
|
|
is very flexible, it can cause problems when your system has other devices
|
|
that are located at the I/O ports that
|
|
.Nm matcd
|
|
is checking for CD-ROM host interfaces. In addition, checking multiple
|
|
locations can cause the boot process to take longer than it could.
|
|
.if t .bp
|
|
.if n .sp
|
|
If you are having these problems, you can solve them by explicitly specifying
|
|
where the CD-ROM host interfaces are located. For example, by default most
|
|
SoundBlaster cards have the Matsushita CD-ROM host interface
|
|
located at I/O port 0x230. (This is 0x10 above the I/O port for the
|
|
audio section of the card.) If this is the case for your system, you could
|
|
change where the kernel looks for the hardware by using the -c option at
|
|
the kernel boot prompt. This will load the kernel and then give you the
|
|
opportunity to change settings for any of the devices included the kernel.
|
|
For example, to change the I/O port for
|
|
.Nm matcd
|
|
adapter zero to 0x340, you would type
|
|
|
|
config> port matcd0c 0x340
|
|
|
|
If you recompile the kernel, you can change the entry in the kernel
|
|
configuration file to specify a specific address by changing an entry
|
|
like this:
|
|
|
|
controller matcd0 at isa? port 0x230 bio
|
|
|
|
With this change, the
|
|
.Nm matcd
|
|
driver will only look at I/O port 0x230 for the first CD-ROM host interface
|
|
and will not disturb any other I/O ports.
|
|
|
|
Once you have adjusted the kernel configuration file, it is necessary
|
|
to configure and recompile the kernel, install it and reboot for the
|
|
changes to take effect.
|
|
.Sh SUPPORTED HARDWARE
|
|
At this time, there are only two known drive models that work with the
|
|
.Nm matcd
|
|
driver:
|
|
.Bl -tag -width CR-123-X -compact -offset indent
|
|
.br
|
|
.It Matsushita CR-562-x
|
|
.br
|
|
.It Matsushita CR-563-x
|
|
.br
|
|
.El
|
|
Most resellers leave these original markings on the drives since the label
|
|
also has the FCC, VDE, CSA and RU certification marks.
|
|
|
|
Both of these drive models have motorized trays. There is also a custom
|
|
version of these drives that does not have the volume control or headphone
|
|
jack (seen on some Tandy computers), but this drive also works with
|
|
.Nm matcd.
|
|
|
|
The Matsushita CR-522-x and CR-523-x CD-ROM drive is not usable with
|
|
.Nm matcd.
|
|
The CR-522 and CR-523 can also be identified from the front as it
|
|
requires a CD-caddy.
|
|
|
|
Drives with IDE interfaces must use an IDE driver.
|
|
|
|
The TEAC CD-55 4X CD-ROM drive also uses the Creative/Panasonic interface
|
|
but the TEAC drive is \fInot\fR compatible with the Matsushita CR-56x drives.
|
|
The TEAC drive cannot be used with
|
|
.Nm matcd.
|
|

.if n .bp
|
|
The most common source of host interface adapters for the Panasonic drives
|
|
are found in products from Creative Labs, including SoundBlaster sound
|
|
cards. There are numerous models of SoundBlaster sound cards, and most
|
|
of the newer cards provide the appropriate interface, sometimes labeled as
|
|
the "Creative/Panasonic" interface.
|
|
|
|
The following host interface adapters are known to work with the
|
|
.Nm matcd
|
|
driver:

Caution: Some of these sound boards can be optionally manufactured to not
|
|
include the Panasonic/Creative interface, so check the board before buying
|
|
solely based on model number.
|
|
|
|
This is by no means a complete list as Creative Labs and other vendors
|
|
that produce sound cards with an identical Creative/Panasonic drive
|
|
interface release new versions of their adapters all the time.
|
|
|
|
In addition to Creative Labs adapters, adapters that are compatible with
|
|
Media Vision, IBM and Lasermate adapters are also supported. However,
|
|
these adapters use a wide range of I/O port addresses, so the driver
|
|
must be reconfigured to locate these adapters.
|
|
|
|
It is important to understand that some manufacturers have a different
|
|
host interface implementation. If you have a board that won't communicate
|
|
with the drives under MS-DOS using the genuine Creative Labs drivers, then
|
|
.Nm matcd
|
|
may not work with that host adapter.

.Sh SUPPORTED OPERATIONS
|
|
The
|
|
.Nm matcd
|
|
driver supports block and character access. Partition "a" returns
|
|
2048-byte User Data blocks from data CDs. Partition "c" returns the full
|
|
2352-byte Frames from any type of CD, including audio CDs. (Partition
|
|
"c" cannot be "mounted" with cd9660 or other filesystem emulators.)
|
|
No other partitions are supported.
|
|
|
|
The
|
|
.Nm matcdl
|
|
devices work the same as the normal
|
|
.Nm matcd
|
|
devices except that the drive trays are locked and
|
|
remain locked until all of the devs on that drive are closed.
|

|
stops playing a disc.
|
|
.It CDIOCEJECT
|
|
opens the disc tray.
|
|
.It CDIOCCLOSE
|
|
closes the disc tray.
|
|
.It CDIOCPREVENT
|
|
blocks further attempts to open the drive door until all devices close
|
|
or a CDIOCALLOW ioctl is issued.
|
|
.It CDIOCALLOW
|
|
unlocks the drive door if it was locked. This ioctl is rejected if
|
|
any locking devices are open.
|
|
.It CDIOCGETVOL
|
|
returns the current volume settings of the drive.
|
|
.It CDIOCSETVOL
|
|
sets the volume settings of the drive.
|
|
.It CDIOCSETSTEREO
|
|
causes the left channel audio to be sent to the left channel output and the
|
|
right channel audio is sent to the right channel output. This is the
|
|
default state.
|
|
.It CDIOCSETMUTE
|
|
causes the audio output to be turned off. The drive continues to read
|
|
the audio on the disc and that audio is discarded until the audio is
|
|
turned back on.

|
.It CDIOCSETLEFT
|
|
causes the left channel audio to be sent to the left and right channel outputs.

|

.Sh NOTES
|
|
.Pp
|
|
The Creative/Panasonic interface does not use interrupts or DMA
|
|
although the drives themselves are capable of using both.
|
|
|
|
If the disc tray is opened while one or more partitions are open, further
|
|
I/O to all partitions on the drive will be rejected until all partitions
|
|
are closed.
|
|
|
|
There must be a drive on each host interface that is addressed as
|
|
physical drive 0. If this isn't the case, the driver will be unable
|
|
to find the host interface or any of the connected drives.
|
|
|
|
Drives on a second host interface start are considered logical
|
|
drives 4-7, 8-11 on the third interface and 12-15 on the fourth.
|
|
|
|
The first drive on the second host interface is logical drive 4 regardless
|
|
of how many drives are present on the first host interface.
|
|
|
|
Host interfaces are numbered in the order they are declared in the
|
|
kernel configuration file, or in the order they are found if the kernel
|
|
configuration file uses "?" for the port address. Host interface
|
|
numbers are always contiguous.
