Introduction 3
Introduction
Congratulations on the purchase of your Toshiba XM-6201 CD-ROM drive. Read
carefully through this manual in order to install the drive and learn how to use it.
This manual guides you gently through the process of setting up the drive and fitting the
drive into your computer. But don’t worry! Take one step at a time and read each section
all the way through before you start.
But first, a word about
speed!
Just How Fast is FAST ?
To make a CD-ROM drive qualify as a “32-speed” or “32X” drive, the manufacturer
needs only make the disk spin at 32 times the speed of a “single-speed” drive. So calling
a drive 32X gives the buyer very little information.
The real speed of a CD-ROM drive – how fast the drive delivers the data to your
computer – is governed by three main factors:
Seek time and access time have a major influence on applications which read data in
many small, non-contiguous blocks, such as reference works and games. These times are
measured in milliseconds (msec) – the lower the figure the better.
Sustained transfer rate affects applications which read a large amount of data in one go
- such as when you install software from CD or when you transfer large archived files.
This speed is measured in kilobytes per second (kB/sec) - the higher the figure the better.
From Audio to Data
CD-ROM drives were developed from audio CD technology, in which a constant speed
is required. Early CD-ROM drives used the same spin speed as audio CD players, 200
RPM. This gave a data transfer rate of 150 kB/sec. This was called a “single-speed”
drive.
While 150 kB/sec is ideal for audio, it has proved too slow for applications such as
databases, games, video and large archived files. Manufacturers have since increased the
seek time how long it takes to find a particular piece of data on
the disk
access time the average time taken to position the laser head and
start transferring data
sustained transfer rate how fast the drive can read data from the disk and
pass it to your computer

4 TOSHIBA XM-6201 CD-ROM Drive
speed at which the disk spins to twice as fast (2X), three times as fast (3X) and so on.
This means that the data (rather than audio tracks) can be read at twice, three times, four
times the speed, and so on as drives become even faster. This gives a theoretical data
transfer rate of 300 kB/sec (2X), 450 kB/sec (3X) and more as the spin speed increases.
However, just spinning the disk faster does not necessarily mean the data is accessed or
transferred any faster. One of the reasons for this is that the laser head must be moved in
and out between the centre and the edge of the disk. The quality of the motor which
moves the laser head is vital as it must accelerate and then stop at exactly the right place
on the disk many thousands of times at incredible speeds.
The quality of the laser mechanism, on-board caching, error correction techniques, the
type of interface and the driver software can all have an effect on the access speed and
transfer rate. This means that a CD-ROM drive rated at 4800 kB/sec might not really be
able to achieve that speed because of bottlenecks elsewhere in the drive.
A 32X drive with slow seek time, poor caching and poor error correction will cause
performance problems. Multimedia applications expect data to be delivered at an
acceptable rate. If the data is not delivered fast enough you notice a degradation in sound
or video quality while the computer waits for the next block of data from the CD-ROM
drive. Sometimes the poor data transfer speed can cause synchronisation between audio
and video material or between data and graphics to fail.
Connecting the CD-ROM: SCSI vs EIDE
There are two main ways in which a CD-ROM drive can be connected to your computer,
SCSI (Small Computer Systems Interface) and EIDE (Enhanced IDE). The method you
choose will depend on your computer and how you intend to use the drive.
SCSI Interface
If your PC is fitted with a SCSI interface card, up to seven SCSI devices can be attached
to the interface card, including hard disk drives, CD-ROM drives, scanners, tape drives
and more. When data is being read from a SCSI CD-ROM drive, very little CPU (central
processing unit) time is taken up - the interface card does the work and delivers the data
to the computer. SCSI is the preferred interface for business systems.
EIDE Interface
Most PC motherboards now include a built-in EIDE interface, allowing floppy drives,
super-floppies, hard disk drives and CD-ROM drives to be connected directly to the
motherboard without the need for a separate interface card. Many sound cards also have
an integrated EIDE interface.
EIDE is a convenient way of connecting a CD-ROM drive to your computer, but during
data access and transfer, 100% of the CPU time is used. This can slow down some
applications, especially under multi-tasking, multi-threaded operating systems such as
OS/2, Windows 95 and Windows NT

So How Fast is FAST? 5
So How Fast is FAST?
It depends, but one thing is certain, simply looking at the “speed” of the drive is not
enough. To get the full picture, look at the seek time, access time, sustained transfer rate
and quality of components.
Your Toshiba XM-6201 CD-ROM Drive
The XM-6201 is a one of the fastest CD-ROM drives currently available. Its features
include:
❑32X speed. That is 32 times as fast as the first generation of CD-ROM drives
❑Tray operation. Just open the tray, drop in a disk and close the tray again
❑4800 Kb per second data access. Fast enough for the most demanding
application
❑SCSI-2 interface. Just set the SCSI ID, plug in the drive to an existing SCSI
interface card, load your drivers and go.
What Happens Next?
This manual shows you how to set up and install your CD-ROM drive. You will need
enough room to work – and a small cross-head screwdriver and enough room to take the
case off your computer.
SCSI Drives
The XM-6201 is a SCSI-2 device; SCSI stands for Small Computer Systems Interface.
This is a means of adding devices such as CD-ROM drives, scanners and tape drives to
computers.

6 TOSHIBA XM-6201 CD-ROM Drive
To add a SCSI device to your computer, the computer must have a SCSI interface card
already in place. The interface card fits into one of the slots inside your computer and
connects to SCSI devices via a 50-core cable.
Your SCSI interface card will have been supplied with drivers for a range of SCSI
devices, including CD-ROM drives. You should now:
❑Check that you have a SCSI interface card in your computer. If you don’t
have a SCSI interface card you should contact your dealer and obtain one
❑Locate the original disks supplied with the SCSI interface card. You will
need to load drivers from these disks when the CD-ROM drive is fitted.
NOTE
Before you begin installing the CD-ROM drive, make sure the
computer is switched off and the power cable is disconnected
from the computer.

Installing the Drive 7
Installing the Drive
Setting up the CD-ROM drive
This section shows you how to set up the drive and install it in your computer. These are
the steps you will follow:
❑Set the jumper plugs on the drive (if necessary)
❑Remove the computer’s case
❑Find a free drive bay at the front of the computer
❑Slide in the drive
❑Connect the drive to your SCSI interface card
❑Connect a power cable to your drive
❑Connect a sound cable to your drive (optional)
❑Replace the computer’s case
❑Load the driver software to make your computer recognise the CD-ROM drive.
If you are not familiar with the inside of your computer or if you feel the need for a little
help, find someone who has more experience and who can give you a hand. If there is
no-one to help, don’t worry, every step of the way is fully explained.
Read through this whole section covering all of the points above before you make a start.
The description and diagrams here are based on a typical desk-top computer. Your
computer casing or layout may be different to this. If so, refer to your computer’s user
guide for details of fitting additional drives.
NOTE
Before you work through the following steps, switch off the
computer and disconnect it from the mains power supply.
Set the Jumpers on the Drive
The drive has a block of jumpers which must be set correctly before you attach the drive
to your interface card.
The jumpers are towards the left as you look at the back of the drive. The settings of
these jumpers may need to be changed, depending on your needs. The two settings for
each jumper are ON and OFF, sometimes referred to as 1 and 0. If the connector plug
connects the two pins, the setting is ON, if the connector plug touches only one pin, it is
OFF.

8 TOSHIBA XM-6201 CD-ROM Drive
The block of jumpers looks like this:
The SCSI ID number
The leftmost three jumpers on the block are used to set the SCSI ID number. The factory
setting of these jumpers is OFF OFF OFF, giving the ID number 0. If you are using only
one drive, or if the CD-ROM drive is the first SCSI device connected to your SCSI
interface card, leave these jumpers as they are.
If you want to chain a number of drives or other SCSI devices together, set the jumpers
on each such that the drives are numbered 0, 1, 2 and so on. The last line of the table
shows the setting for a SCSI ID of 7 - this is usually reserved for the SCSI interface card
itself.
The jumper settings for eight possible ID numbers are shown below:
SCSI ID 7 is usually reserved for the SCSI interface card itself.
The Parity Jumper
This jumper, number 4, should be set to OFF.
Termination Jumper
If the drive is one of a series of drives - but not the last, this jumper, number 5, should
be set to OFF. If the drive is the last in a series of SCSI devices, this jumper should be set
to ON.
See also the Termination Power Supply Jumper below.

Eject Suppression Jumper 9
Eject Suppression Jumper
Jumper 6 is used to inhibit the operation of the drive’s EJECT button. When this jumper
is set to ON, the EJECT button will not operate. Set the jumper to OFF to allow the
EJECT button to operate.
The Test Jumper
Jumper 7 should always be set to OFF.
Terminator Power Supply Jumper
Toshiba SCSI CD-ROM drives are capable of supplying power to the terminating
resistors on the SCSI bus. The power supply is set to ON or OFF using this jumper.
According to the SCSI specifications, at least one device on the SCSI bus must supply
terminator power, but other devices on the bus may also supply power. Therefore the
terminator power jumper may always be left in the ON position.
Remove the Computer’s Case
Every computer casing is different from every other, but the casing is usually attached to
the frame by a number of screws at the back. Turn the computer’s case right around so
you can see the back and look for four or six screws around the edge of the casing.
Remove the screws and put them somewhere safe. The outside casing will now either lift
or slide off. Put it safely out of your way so you have room to work.
Find a Free Drive Bay
The internal CD-ROM drive fits into any free half-height drive slot at the front of the
computer. Free drive slots usually have a cover plate of metal or plastic which conceals
the front of the slot. This is sometimes clipped in place, or sometimes fixed with two
screws. Remove the cover plate ready to fit the drive.

10 TOSHIBA XM-6201 CD-ROM Drive
Fit The Drive
Carefully slide the drive into the opening so that the disk tray shows at the front of the
computer:
Before you push the drive all the way in, you should connect the interface cable and
power cable to the back of the drive. It will be easier to connect the cables first before
you push the drive fully into the slot.
Connect the Drive to your SCSI Interface Card
Your computer should have at least one free connector on a cable attached to a SCSI
interface card. The 50-pin connector fits into the socket on the back of the drive. One
edge of the ribbon cable is marked with a stripe or is coloured red, this connects to pin 1
on the plug. The corresponding pin 1 on the CD-ROM drive’s interface connector is next
to the drive’s power connector. Make sure that pin 1 on the plug connects to pin 1 on the
drive.
Carefully push the connector into the socket, making sure it fits all the way in.
Connect the Drive to a Power Lead
You should have a small DC power lead inside your computer, ready to connect to the
back of the drive. If there is no power lead available, consult your computer dealer or
support service. You may need a “power splitter lead” - a Y shaped cable which taps two
power outputs from one input.
The connector should only fit one way into the power socket on the back of the drive.
One face of the plug has chamfered edges - make sure the plug fits into the socket
the right way up. Carefully push the plug all the way into the socket.

Connect a Sound Cable to your Drive 11
Connect a Sound Cable to your Drive
If you have a sound card and speakers and would like to play audio CDs through your
computer, you will need to get a sound cable from your supplier. Each sound card
requires a different cable, so you will need to tell your supplier which sound card you
have and that you have a Toshiba XM-6201B CD-ROM drive. Your supplier should be
able to supply you with a suitable inexpensive cable.
The sound cable connects to your sound card at one end and to the audio connector at the
rear left of the drive at the other. You will need to refer to the instructions which
accompanied your sound card for details of any sound-driver software required.
Replace the Computer’s Case
You can now push the drive all the way into the slot and, if necessary, fix it in place with
screws on either side. Replace the computer’s cover and replace all of the fixing screws.
CD-ROM Driver Software
DOS and Windows 3.x
Your SCSI interface card should have been supplied with additional driver software for a
range of SCSI devices, including CD-ROM drives. Some computers are supplied with a
SCSI interface card already fitted. If this is the case, the SCSI driver software may be in
a directory called \SCSI (or similar) on your hard disk, or the software may be on a
floppy disk supplied with your computer.
Locate the driver software and follow its instructions for adding driver software to
support a CD-ROM drive.
32 bit Operating Systems
Windows 95, Windows NT and OS/2 all include drivers for a wide range of SCSI
devices. To make your Toshiba XM-6201 work with these operating systems you should
refer to your operating system’s user guide for details of adding SCSI devices.
Care and Use of Your CD-ROM Drive
Most aspects of caring for your CD-ROM drive are simple matters of common sense.
However, here is a list of points to remember:
❑Do not expose your CD-ROM drive to extreme temperatures, excessive dust or
high humidity
❑Do not install your CD-ROM drive near any device that produces strong
electrical waves or magnetic fields

12 TOSHIBA XM-6201 CD-ROM Drive
❑There are no user serviceable parts in your CD-ROM drive
❑Install your CD-ROM drive on a flat and stable surface where it will not
experience vibration.
The Controls
Your CD-ROM drive has the following controls and features:
❑Disk tray
❑EJECT button
❑Emergency Eject
❑BUSY light
❑Headphones socket
❑Volume control
The BUSY Light
When you put a disk into your CD-ROM drive, the busy light flashes slowly as it
attempts to locate a disk. It then indicates one of the following conditions:
During data transfer the BUSY light remains on.
The EJECT Button
The eject button is used to open the disk tray so you can put in or take out a disk.
Make sure the Eject Inhibit jumper (jumper 6) is set to OFF. If this jumper is set to ON
the EJECT button will not operate. The drive then expects all control, including the
ability to eject the disk, to come from the computer.
Emergency Eject
If the power supply to the drive fails, you can still remove the disk from the drive. Next
to the eject button on the front of the drive is a small opening. Insert a pointed instrument
(a straightened paper clip is ideal) into the opening and the disk tray will open.
The Headphones Socket
The headphones socket is used to connect headphones to your CD-ROM drive.
However, it can also be used to connect the CD-ROM drive to other equipment. For
example, you could connect the drive to an audio amplifier or a cassette recorder.
The VOLUME Control
The volume control is used to control the level of the audio signal from the headphones
socket. The volume control does not affect the level of the signal sent to the audio output
on the back of the drives.
1. The BUSY light goes out. The CD-ROM drive is ready to read data from the
disk.
2. The BUSY light flashes slowly. The disk may be dirty.

Operating the Disk Tray 13
Operating the Disk Tray
Make sure that on desk-top computers, or if your external
CD-ROM drive is on your desk, that no drinks or other delicate
objects stand in front of the disk tray!
To open the disk tray and remove your disk, just press the Eject button:
Loading a Disk
After putting a disk into the drive, gently push on the front of the open disk tray. The tray
automatically slides into the drive.
