Mitsumi FX Series IDE CD-ROM Drive Installation Manual 3
Introduction
Thank you for purchasing an FX Series internal IDE CD-ROM drive. For
optimal performance and greater reliability, your new drive uses a combination of
Constant Angular Velocity (CAV) and Constant Linear Velocity (CLV) modes to
vary the spin rate, making it ideal for quickly installing software, running a CD-
ROM based database, or driving demanding multimedia applications.
FX Series CD-ROM drives are capable of reading compact discs meeting
international standards, such as Photo CD, ISO 9660, multi-session, CD-Extra and
XA (eXtended Architecture) discs. This manual was written to help you install and
use your CD-ROM drive. Please read it carefully before installing your drive, and
refer to it if you should have any difficulty with your drive in the future.
The FX Series internal CD-ROM drive connects with your PC system using the
new industry standard ATAPI/IDE (Advanced Technology Attachment Packet
Interface/Integrated Drive Electronics) definition. This standard allows a CD-ROM
drive to work with device drivers supplied by companies that write operating system
software (Microsoft Windows 95/98, NT, IBM OS/2, etc.).
This means that the CD-ROM drive can be controlled through an IDE interface
that may already exist in your system, either from the motherboard or an expansion
card. Some sound cards also provide an IDE connection; however, we recommend
connecting the CD-ROM drive to a PCI based IDE port for maximum performance.
If you already have an IDE interface controlling a hard drive, you may attach the
FX Series drive as a second device on its cable. Alternatively, you can connect the
FX Series drive to an IDE interface card. This may be required if all IDE connec-
tors are being used by built-in hard disk drives in your system. If you do not have an
IDE card, or if your IDE card is now controlling two hard drives on the same cable,
you will need a second IDE card to control the CD-ROM drive. Some newer IDE
cards may have two ports, supporting up to two devices each. Refer to your IDE
interface user manual for more information about your IDE ports and configurations.
We have created our World Wide Web pages to inform you of new developments
at Mitsumi. Please visit our Web pages on the Internet at www.mitsumi.com for
your drive’s specifications, the latest CD-ROM drivers, and technical support.
Safety Information
Please follow all safety warnings and instructions printed in this manual and on
the CD-ROM drive to avoid damaging your drive or harming yourself.
- Unplug the computer power cord from the wall outlet before doing anything

inside the computer enclosure.
- Never attempt to service the drive yourself. There are no user serviceable parts
inside the unit. Opening or removing the cover can expose you to dangerous
voltage levels, laser beams, and other hazards.
- Do not attempt to open the unit. It will void your warranty. The laser beam used
by the CD-ROM drive can be harmful to the eyes. All service procedures should
be performed by an authorized dealer or distributor.
- Note that the noise level of compact disc audio is much lower than that of an
analog audio source. Do not attempt to set the speaker sound level by listening to
the noise level. Too high a setting can damage your speakers. Begin with the
sound level set low, then gradually increase the volume to the desired level.
Care and Handling of Your Drive and Discs

Drive Care
- Do not drop or jolt the drive. The lens and prism are delicate and can be dam-
aged by rough handling.
- Do not use your drive near any liquid, and don’t bring liquids near your drive.
- To clean the drive, use a clean, soft cloth, dampened with water, on the outside of
the drive only. Thinner, benzene, or alcohol-based solvents can mar the finish.
- Keep your drive away from dust and smoke. CD-ROM drives are susceptible to
airborne contaminants.
- Do not install your drive in a location that exceeds the maximum operating
temperature.
- For best results, use only discs that bear the logo:
- Never place anything on top of the disc tray except a disc. Do not push down on
the disc tray when it is open.
Disc Handling
- Keep your CD-ROM discs clean. Use a soft, clean cloth dampened with water or
a commercial disc cleaning solution. Dry the disc thoroughly before inserting it in
the drive.
- Wipe the discs radially, from the center straight out to the edge, NEVER in a
circular motion.
- A scratch in the shape of an arc could make your disc unreadable.
- Avoid touching the disc surface. Always handle discs by their edges.
- Never write on a disc with a ball-point pen or pencil. A scratch on the label side
of a disc can damage the data layer.

6 Mitsumi FX Series IDE CD-ROM Drive Installation Manual
- Avoid exposing discs to direct sunlight, and avoid storing them in areas subject to
high temperature or high humidity.
- Store discs in cases to avoid dust, dirt, scratches, and bending.
- Never bend a disc.
What You Need to Install the Drive
Here’s a list of all the things you’ll need to install your CD-ROM drive:
- Your FX Series CD-ROM drive unit.
- 2~4 mounting screws, type M3, length 5mm (0.2 inch) maximum.
- 40-pin IDE interface ribbon cable with either 2 or 3 connectors on it. A 40-pin
ribbon cable (data cable) controls the CD-ROM drive and provides for data
transfer from the drive to the computer. The colored stripe on the cable desig-
nates pin one and should line up with pin one as marked on any port where it is
connected.
- Power Cable. A 4-wire cable runs from the power supply in your computer to the
DC power plug on the back of the CD-ROM drive.This connector is keyed so
that it plugs in only one way. If all the power connectors from your power supply
are used, you can buy a Y-splitter power cable at an electronics store.
- 3.5 inch floppy disk, containing device driver software and setup utilities for MS
DOS.
You may need:
- An IDE interface controller card.
- A second 40-pin IDE interface ribbon cable.
- Mounting rails.
If you have a sound card in your computer, you will probably want to hear stereo
audio through your sound card and speakers. In order to play audio from your CD-
ROM drive, you will need to connect the CD-ROM drive to your sound card with a
4-pin audio cable with an analog audio connector for IDE on one end and the
connector for your sound card on the other.
Because there are so many different kinds of sound cards, each requiring its own
type of audio connector, a suitable audio cable was probably not supplied with your
CD-ROM drive. Even if there was an audio cable included, it is possible that it will
not work with your sound card. Contact your sound card manufacturer for the
proper cable. Pin-outs are labeled on the back of the CD-ROM drive and are shown
in this manual.

Mitsumi FX Series IDE CD-ROM Drive Installation Manual 7
Hardware Installation
It’s always a good idea to perform computer hardware installation in a clean,
well-lit area. This makes it easier to see switches, jumpers, and cable connectors,
and less likely that you will lose screws or drop and damage delicate components.
First, turn off your computer and unplug the power cable. Turn off and unplug
any peripheral devices that may get in your way. Before touching any electrical
circuit boards, ground yourself by touching the computer chassis or power supply.
Loosen the cover screws and remove the cover from the computer case. Cases
vary widely, but the cover is usually secured by two or more screws. It may lift off
or slide off from the top, back, or side.
Drive Installation Considerations
The CD-ROM drive can be installed in either a horizontal or a vertical position.
The image below represents the vertical position. The newer models have 4 notches
in the tray to prevent your CD from falling off when your drive is mounted verti-
cally.
- If your drive has 4 notches, then it may be installed with the eject button at either
the top or the bottom.
- If your drive has only 2 notches, then mount it so that the notches are at the
bottom.
Before installing or removing the CD-ROM drive, make sure that there is no CD
12x/24x

8 Mitsumi FX Series IDE CD-ROM Drive Installation Manual
If your IDE port is currently controlling one hard drive, the hard disk drive
may be configured either as a single drive or as a master drive. Some hard drives
may require that their jumpers be changed in order to add a second drive to the same
cable. Refer to your hard drive manual, or call your hard drive manufacturer for
jumper settings.
Attach the spare connector on your hard drive ribbon cable to the IDE interface
port of the CD-ROM drive. The colored stripe side of the cable is pin 1.
in the drive and that the disc tray is closed.
Find an empty drive bay for your CD-ROM drive. Empty drive bays may have a
plastic or front plate; these covers can be gently popped out, or the mounting screws
can be removed. To determine whether you need to use mounting rails on the side
of your drive, insert the drive in the open drive bay from the front. If the drive fits
snugly with little or no clearance on either side of the drive, you do not need to use
mounting rails. The drive can be mounted directly on the chassis of the computer.
Simply secure the drive in place with the mounting screws.
CAUTION: Use only M3 screws, no longer than 5mm (0.2 inch).
If you must use mounting rails, line up the holes in the rails with the holes in the
side of the drive and attach with screws. Check the positioning of the rails by sliding
the drive into the bay before you connect any cables. Rails are usually available at
computer supply stores.
Device Configuration
You have three options for installing a new IDE device into your system:
Option 1: Attach the FX Series CD-ROM drive as a “slave” to the same cable
on which your hard disk drive is connected. (This is known as “daisy-chaining.”)
On the back of your CD-ROM drive you will find the device configuration
jumper. It is a set of six pins with a plastic jumper on two of them. There are three
jumper positions: CS (Cable Select), SL (Slave), and MA (Master). The CD-ROM
drive leaves the factory set as a slave. Use this default setting for this configuration.

Mitsumi FX Series IDE CD-ROM Drive Installation Manual 9
Option 2: Connect the CD-ROM drive to a second IDE controller port.
If your computer has more than one IDE port, it is a good idea to use separate
IDE ports for your hard drive and CD-ROM drive. This will ensure that your hard
drive’s performance and speed are not affected by having the CD-ROM drive on the
same cable. It will also be easier to add another CD-ROM drive to the second cable
later.
If your CD-ROM drive will be the only device attached to this cable on the
second port, set its configuration jumper to master. Connect a 40-pin ribbon cable
from the IDE interface port on the rear of the CD-ROM drive to the interface port on
the controller card or motherboard. Line up the colored stripe on the cable to pin 1
at both connections.
Option 3: Connect the CD-ROM to a 40-pin IDE port on a sound card.
Follow the instructions in your sound card manual. If you are getting the error
“Unable to Detect ATAPI IDE CD-ROM Drive,” then:
1. Make sure this 40-pin connection is not labeled Mitsumi. This is an old propri-
etary interface and is not compatible with our new IDE drives. Many older sound
cards will not have 40-pin ports for IDE CD-ROM drives.
2. Check to see if you have a second 40-pin IDE port on your motherboard. This is
probably causing a conflict with the IDE port on the sound card as both may be
set at Secondary IDE address 170 and Interrupt 15. Most systems will only
recognize the Primary and Secondary IDE ports. There can be only one Second-
ary IDE port enabled in the system. See Custom Installation for more informa-
tion about IDE.
The preferred choice is to disable the IDE port on sound card and run the 40-pin
cable from the CD-ROM drive to the second 40-pin IDE port on the motherboard.
Connect only the audio cable from the CD-ROM to the sound card. If the Mitsumi
IDE driver software was installed you don’t need to install the software again.
However you may need to reinstall the sound card software. If it asks about the CD-
ROM drive, choose NONE so the sound card does not look at its own IDE port for
the CD-ROM drive. or
Disable the second IDE port on the motherboard. Keep the CD-ROM drive 40-
pin cable connected to the sound card IDE port.
3. If you don’t have a second 40-pin IDE port on your system and you still get the
error, consult your sound card manual to find the IDE port address setting on that
sound card. Our software looks for address 170 and Interrupt 15 automatically.
Some sound cards provide unique IDE settings.

10 Mitsumi FX Series IDE CD-ROM Drive Installation Manual
Configure the sound card at IDE address 170 and Interrupt 15. This may be
done with physical jumpers on the sound card that set the IDE port address and
interrupt. If there are none, you may be able to configure through the sound card’s
software utility program. If the sound card supports IDE channel 3 & 4, see Custom
Installation section for help. If you need further assistance call the sound card’s
technical support. All sound cards are unique and may require special instructions.
Software Installation
Once the CD-ROM drive is configured to your system, software installation is
simple and straightforward. The MS-DOS device driver makes all the necessary
modifications to your system to activate the information and utilities you can use if
things don’t go quite right.
Updates of the MS-DOS IDE device driver are available through our World
Wide Web site, www.mitsumi.com, as they are released. If you did not receive a
floppy diskette with the label that is pictured below, please download the driver and
utilities from our web page.
NOTE: The specifications for your CD-ROM drive are included as .pdf docu-
ments on the diskette and are also available through our Web site.
Please note that device drivers for Windows 95/98, NT, and OS/2 as well as
other operating systems are furnished by the operating system manufacturers. These
operating systems supply industry standard, general purpose ATAPI/IDE drivers for
CD-ROM drives. If you are going to boot directly into MS-DOS when using one of
these operating systems, the boot disk must have the driver installed for the CD-
ROM drive to be available.

Installation for Windows 95/98
Microsoft provides protected mode drivers for Windows 95/98 as a part of the
operating system. The FX Series CD-ROM drives are ATAPI/IDE drives supported
under Windows 95/98’s generic IDE protected mode driver. You will not need to
install the MS-DOS device driver to use the CD-ROM drive, unless you are planning
to use the MS-DOS mode.
When you are adding the CD-ROM drive to Windows 95/98, go to Control Panel
and click on Add New Hardware. Let Windows 95/98 search CD-ROM drives
automatically by following on-line instructions. When you finish Add New Hard-
ware, restart Windows 95/98. If this method does not detect your CD-ROM drive,
refer to the Troubleshooting section in this manual.
Drive Test and MS-DOS Driver Installation
Use the Device Driver & Setup Utilities diskette that came with your CD-ROM
drive for drive testing and MS-DOS driver installation. Updates of this diskette are
available for you to download from our web site at www.mitsumi.com. The Disc
Inspector (DI.EXE) program must run from MS-DOS, not DOS Windows. For
Windows 95/98, be sure to reboot the system in MS-DOS by selecting “Restart the
computer in MS-DOS mode” before proceeding.
1. If running Windows 95/98, restart the computer in MS-DOS mode. From the
“Start” menu, select “Shut Down...” and then select “Restart the computer in MS-
DOS mode.”
2. Insert the supplied installation disk into drive A (or B). Be sure the write protect
notch is in the WRITE ENABLED (CLOSED) position (see image on next page).
Disc Inspector will write a log file to the current logged directory. You may copy
all files from the installation disk to your hard disk subdirectory, such as C:\DI, so
that Disc Inspector is available for future use.

Disc Inspector.
9. To run a test, hold the ALT key and hit the highlighted letter:
ALT-M: Mechanical and Interface
ALT-A: Audio Channels
ALT-D: Data Transfer and Performance.
10. You will see a passed or failed message after each test is done.
11. Passing these tests verifies that the drive is working properly. If any of the tests
fail, refer to the Troubleshooting section for help.
12. Hit the ESC key to exit the testing section.
13. From the Install menu, hit the ENTER key.
14. Follow the instructions on the screen using the driver default settings.
15. When the installation is complete, remove the diskette and reboot the system.
If the Mitsumi CD-ROM drive was not detected when your system was analyzed
by Disc Inspector, you have an IDE configuration problem. See the Device Con-
figuration section of this manual for troubleshooting assistance.
After the CD-ROM drive installation is complete and you have rebooted your
computer, the drive letter of your CD-ROM drive will be the next available drive
letter on your system. For example, if your last drive or drive partition is letter C:,
your CD-ROM will be letter D:.
With a disc in the CD-ROM drive, type DIR D:. Your computer should display a
directory of files on the CD-ROM disc. You are now ready to start using your CD-
ROM drive.

Mitsumi FX Series IDE CD-ROM Drive Installation Manual 13
What the Installation Procedure Does
1. Creates a device driver line in your CONFIG.SYS file.
In order for your computer to recognize the CD-ROM drive, a device driver file
must be copied to your computer and loaded by CONFIG.SYS when you start your
computer. The device driver for your FX Series CD-ROM drive is named
MTMCDAI.SYS. The installation program will create a subdirectory named MTM
(unless you specify another directory name) on your C: drive, or the drive you
specified. It then copies the MTMCDAI.SYS file to this directory.
The installation program adds these lines to your CONFIG.SYS file:
rem ---------- MTM ATAPI CD-ROM ----------
DEVICE=C:\MTM\MTMCDAI.SYS /D:MTMIDE01
rem ---------- MTM ATAPI CD-ROM ----------
The middle line tells the computer to go to the C: subdirectory MTM, and load
the MTMCDAI.SYS file into memory. MTMIDE01 is the device name the installer
has given to your CD-ROM drive. It will be used by Microsoft CD-ROM Exten-
sions (MSCDEX) to assign a DOS drive letter to the CD-ROM device.
2. Creates an MSCDEX line in your AUTOEXEC.BAT file.
Microsoft CD-ROM Extensions (MSCDEX) is a program that allows a CD-
ROM disc to be accessed using DOS commands. It assigns a DOS drive letter to the
CD-ROM device, and "interprets" the CD-ROM file format. If you are currently
using DOS version 6.0 or later, you will find the file MSCDEX.EXE in your DOS
directory.
The installation program will add these lines to your AUTOEXEC.BAT file:
rem ---------- MTM ATAPI CD-ROM ----------
C:\DOS\MSCDEX.EXE /D:MTMIDE01 /M:10
rem ---------- MTM ATAPI CD-ROM ----------
The middle line tells your computer to find the device that uses the name
MTMIDE01 and assign the next available drive letter to it. The drive name must be
the same defined in CONFIG.SYS; otherwise the CD-ROM drive will not be found.
Do not specify any subdirectory name as a drive name. By doing so, the
subdirectory may be damaged.
/M:10 is a software switch that tells your computer to reserve 10 buffers in

14 Mitsumi FX Series IDE CD-ROM Drive Installation Manual
memory for faster CD-ROM access. For more information on MSCDEX param-
eters, go to the DOS directory and type HELP. Choose MSCDEX from the list of
files and press ENTER.
Custom Installation
In most instances, the default configuration used in the Installation section will
be sufficient for your system. If you have problems with the installation of your
drive, have other IDE devices that may be causing a conflict, or would like to
customize your installation, the following information may be pertinent.
[drive:][path]MTMCDAI.SYS specifies the location (drive and directory) and
name of the device driver file. [/D:devicename] specifies the device name of the
CD-ROM drive (8 characters maximum). For example:
DEVICE=C:\MTM\MTMCDAI.SYS /D:MTMIDE01
In this line, the device name is MTMIDE01. The device name specified in the
MSCDEX.EXE line in the AUTOEXEC.BAT file must be identical to this.
[/P:xxx,yy] specifies the IDE port base address (xxx), and the interrupt request
channel (yy).
xxx = 1f0 Primary (Channel 1)
170 Secondary (Channel 2)
1e8 Channel 3
168 Channel 4
yy = 14 Primary (Channel 1)
15 or 10 Secondary (Channel 2)
12 or 11 Channel 3
10 or 9 Channel 4
The device driver will search all available IDE ports to find the attached CD-
ROM drives. If you need to specify the port addresses and interrupt request
channels, the syntax in the CONFIG.SYS file should be as follows:
If connected to the Primary IDE port:
DEVICE=C:\MTM\MTMCDAI.SYS /D:MTMIDE01 /P:1f0,14
If connected to the Secondary IDE port:
DEVICE=C:\MTM\MTMCDAI.SYS /D:MTMIDE01 /P:170,15
[/A:n] Specifies the audio play mode. For a stereo CD, /A:0 or /A:1 is accept-

Mitsumi FX Series IDE CD-ROM Drive Installation Manual 15
able. For a monaural CD (left or right channel only), /A:1 will play the monaural
audio signal from both right and left channels. Default is n=0. [/U:n] specifies the
door as locked or unlocked. /U:0
GR German
FR French
SP Spanish
IT Italian
JP Japanese
If you want messages in English, it is not necessary to specify a language option.
If you want messages in Japanese, for example, the syntax in the CONFIG.SYS file
would be as follows:
DEVICE=C:\MTM\MTMCDAI.SYS /D:MTMIDE01 /L:JP
2. The MSCDEX.EXE line in AUTOEXEC.BAT is in the following format:
[drive:][path]MSCDEX.EXE [/D:devicename] [/M:xx]
[/L:x]
If you are using MS-DOS 6 or later, a recent version of MSCDEX.EXE should
reside in your DOS directory. Device names used in the MSCDEX line must match
those used in the MTMCDAI line in CONFIG.SYS.
[/M:xx] tells your computer to reserve xx buffers in memory for faster CD-ROM
access. For more information on MSCDEX parameters, go to the DOS directory
and type HELP. Choose MSCDEX from the list of files and press ENTER. [/L:x]
tells your computer to assign a drive letter to the CD-ROM drive.
Smartdrive - Disabling CD-ROM Disc Caching
SMARTDRV in MS-DOS version 6.2, PC-DOS version 6.3 or later was de-
signed to include CD-ROM disc caching. However, if CD-ROM caching is enabled,
some CDs (such as Photo CD) may not work properly. In this case, you should add
a /U switch to the end of the smartdrv line in AUTOEXEC.BAT to disable CD-ROM
caching.
SMARTDRV.EXE /U

NOTE: Test to see if, with only the power cable plugged in, the door opens by
pushing on the open/close button.
If the door opens with only the power cable plugged in to the CD-ROM but does
not open when the 40-pin data cable is also plugged in, then the problem may be
that:
a. The 40-pin data cable is damaged. Try using another 40-pin cable.
b. Pin 1 on the 40-pin cable is not lined up with the colored stripe on cable.
Verify the alignment.
c. You are plugging the 40-pin ribbon cable into a Mitsumi proprietary port.
This is not compatible with the newer Mitsumi IDE drives. A Mitsumi
port is an older technology and works only for the models FX001D,
FX001, LU005S, and LU002S.
If you are still encountering difficulties after eliminating the issues outlined
above, then contact technical support for assistance.
Troubleshooting
This section is designed to help you identify and solve some common problems
you may encounter when installing or operating your CD-ROM drive. Its purpose is
to give you the ability to fix simple problems without having to call technical
support. Most commonly asked questions and solutions are provided at our World
Wide Web site, www.mitsumi.com.
First, refer to the hardware and software installation procedures and make sure
you have followed them correctly. Double-check cable connections, jumper
settings, and any connections that may have been loosened during hardware installa-
tion.
Next, check the software installation to ensure that the CD-ROM device driver is
12x/24x

18 Mitsumi FX Series IDE CD-ROM Drive Installation Manual
on your hard drive, and that the line in CONFIG.SYS that loads the device driver
points to the correct location and file name. If you edited AUTOEXEC.BAT or
CONFIG.SYS after software installation, check for extra or missing spaces, reversed
slashes, etc.
Windows 95/98 and FX Series IDE CD-ROM Drives
Microsoft provides protected mode drivers for Windows 95/98 as a part of the
operating system. The FX Series CD-ROM drives are ATAPI/IDE drives supported
under Windows 95/98’s generic IDE protected mode driver.
When you are adding the CD-ROM drive to Windows 95/98, do the following:
- Select “Start”
- Select “Shutdown”
- Select “Restart the Computer in MS-DOS mode”
When the DOS prompt appears, install the FX Series IDE real-mode device
driver (MTMCDAI.SYS) as described in the Software Installation section. The
Microsoft CD-ROM extensions, MSCDEX.EXE, can be found in the directory
C:\WINDOWS\COMMAND. When you have finished, type EXIT, and Windows
95/98 restarts.
Windows 95/98 will detect the change in the CONFIG.SYS and
AUTOEXEC.BAT files and respond by setting up the correct device drivers in the
Device Manager. The above procedure cannot be done within Windows 95/98. You
must execute the above procedures in MS-DOS.
If you go to the Control Panel and select System, the Device Manager page will
show you a CD-ROM drive with a + sign in front of it. Click on the + sign and you
should see:
MITSUMI CD-ROM !B(or !A)
If your drive was working in DOS and Windows 3.1 before you installed
Windows 95/98, the installation should automatically detect the drive. If it does not,
there may be another issue. The DOS device driver has no problem with a drive on
the Secondary IDE port (Port 170h, IRQ 15) jumpered as a slave (without a master
drive). Windows 95/98, NT and OS/2 may not find a drive set up this way. Change
the jumper setting to master and reinstall the driver using the above method.

The Drive Does Not Operate After Software Installation
Ensure that both ends of the interface cable, audio cable, and power cable are
firmly plugged into the right pins. Make sure there is a disc in the drive and that the
label side of the disc is up.
If the drive was recently moved from a cold environment to a warm one, there
may be condensation on the lens. Remove the disc and leave the drive turned on for
about an hour before using it.
CD-ROM Drive(s) Can No Longer Be Accessed By the System
Check the MSCDEX line in the AUTOEXEC.BAT file. If there was a CD-
ROM drive(s) previously installed, there will probably now be two lines that load
MSCDEX. MSCDEX is a TSR (Terminate and Stay Resident) program that can be
loaded only once; the device names of all CD-ROM drives must be included on the
same line after MSCDEX. For example, if the two lines in your AUTOEXEC.BAT
file are:
C:\DOS\MSCDEX.EXE /D:MTMIDE01
C:\DOS\MSCDEX.EXE /D:MSCD001
they should be combined on one line to read:
C:\DOS\MSCDEX.EXE /D:MTMIDE01 /D:MSCD001
The order in which device names appear is the order in which drive letters will
be assigned to them.
Error “Not Enough Drive Letters Available”
DOS automatically reserves the drive letters A through E for use with local (non-
networked) drives. For example, if you have floppy drives A and B, and hard drives
C, D and E, all the reserved drive letters are already in use. To add a drive letter for
your CD-ROM drive, add the following line to your CONFIG.SYS file:
LASTDRIVE=x
where x is the last drive letter to be reserved (in this case, F).

Error “CDR 101 - Not Ready Reading Drive (X)”
If you have just inserted a disc in the drive, wait a few seconds for the disc to
“spin up” and try again. Check the disc for scratches, dirt, and fingerprints. Make
sure the label side of the disc is up.
Check to see if the disc is a CD-ROM disc, not an audio disc. The CD-ROM
drive will play CD audio discs, but audio discs are not accessible with DOS com-
mands.
Error “CDR 103 - Not ISO 9660 or High Sierra Format”
The disc may be a CD-ROM intended for another computer or operating system,
such as Macintosh or Sun, or it does not contain data in ISO 9660 format.
CD-ROM Sound
There are two types of audio you may find when using CD-ROMs. You may find
either, both, or neither sound in a CD-ROM application.
CD Audio: Data translated directly by your CD-ROM drive into sound. All CD
Audio discs and some CD-ROM discs use this type of sound. You can hear the
audio CD by plugging a set of headphones or powered speakers into the audio jack
on the front of your drive.
Audio files: Data (.WAV or .MID files) which are transferred from your CD-
ROM disc into your computer and translated by a sound card into sound. You need
a sound card to hear this type of audio. If you have a sound card, you need an audio
cable to connect the CD-ROM drive to the sound card. Contact the manufacturer of
your sound card to obtain the correct cable.
Music CDs: If you cannot hear sound from the speakers but can hear sound from
other CD games or data discs, this is a hardware audio cable problem. There is no
standard for audio cables. The cable you have is probably incompatible. Exchange
the audio cable. This is the case even if you can hear no, little, or full sound from a
headset.
If you cannot access music CDs, make sure you are not trying to get a directory
from the audio disc, for example, in file manager. In Windows 3.1 or 3.11, you can
use Media Player to play a music disc. This is located in your accessories window.
Click on the Device menu and choose CD Audio. If it is not listed there, the
Windows driver MCI CD audio is not loaded. Insert a music disc in the drive. Go
to Control Panel | Drivers. Add MCI CD Audio to the system by following the
instructions then close out.
