==========================================================================
0. What is a CD-ROM?
CD-ROM means "Compact Disc Read Only Memory". A CD-ROM is physically
identical to a Digital Audio Compact Disc used in a CD player, but the
bits recorded on it are interpreted as computer data instead of music.
You need to buy a "CD-ROM Drive" and attach it to your computer in
order to use CD-ROMs.
A CD-ROM has several advantages over other forms of data storage, and
a few disadvantages. A CD-ROM can hold about 650 megabytes of data,
the equivalent of thousands of floppy discs. CD-ROMs are not damaged
by magnetic fields or the xrays in airport scanners. The data on
a CD-ROM can be accessed much faster than a tape, but CD-ROMs are
10 to 20 times slower than hard discs.
You cannot write to a CD-ROM. You buy a disc with the data already
recorded on it. There are thousands of titles available.
==========================================================================
1. What are some good sources of CD-ROM discs?
Jim Raehl has compiled an excellent list of sources for inexpensive
CD-ROMs. His list is periodically posted to alt.cd-rom, and is available
via anonymous ftp from cdrom.com:/cdrom/faq_disc.
You can get a list of about 85 CD-ROM titles by sending a blank message
to CD-ROM@micromed.net.netcom.com [ Several people have had trouble
getting the list, so I have made it available for anonymous ftp from
cdrom.com:/cdrom/micro.med ]

What You Need
Setup
A list of suppliers of CD-ROM hardware and software is also included.
==========================================================================
5. Why are CD-ROM drives so slow?
Compact discs were originally designed for music. When you are
listening to "Willie Nelson's Greatest Hits", you are accessing the
data sequentially and at a very regular speed. The only time you need
to seek is when you decide to skip over a song, or back up and listen
to "Always on my Mind" one more time.
In order to fit as much music as possible onto the disc, the data
is recorded at the same linear density near the outer edge of the disc
as it is near the center, so there is more information in the outside
tracks than in the inside tracks. In order to deliver a steady rate
of data, the linear velocity of the disc moving under the head is
constant, so the angular velocity of the disc changes when the head
moves from the center toward the outside tracks. This is no big deal
when you are playing music, but when you are trying to do random access
to a CD-ROM, the need to accelerate and decelerate the disc is the biggest
obstacle to making it faster. Most magnetic discs spin at a constant
angular velocity, so the data density decreases toward the outside of the
disk, but seeks are faster.
A few other reasons that CD-ROMs are slow: Optical disc heads tend to be
heavier than magnetic disk heads, so they have more inertia, and take
longer to stablize onto a new track. Many CD-ROMs contain too much data
to make effective use of RAM caches.
As time goes by, CD-ROM drives will get a little faster, but don't expect
any miracles.
==========================================================================
6. Is it important to have a fast CD-ROM? Does 300ms vs 700ms really matter?
It depends on what applications you will be using. Many CD-ROMs
are just big archives of stuff, and you can copy individual programs
to your hard disk before using them so speed is not really very
important. But if you are going to be using large ramdom-access
databases, or any kind of interactive multi-media applications, then
the speed difference is very noticeable.
==========================================================================
7. Is it important to buy a fully SCSI compatible drive?
Several CD-ROM drives only support a sub-set of SCSI, and usually
come with their own semi-SCSI controller card. Full SCSI compatible
drives usually cost more, but are better if you already have a SCSI
controller and want to daisy chain several devices, or if you want to
be able to use the drive on different machine types.
==========================================================================
8. Where can I get information on SCSI controllers for CD-ROM drives?
Many SCSI drive vendors recommend the Adaptec 1542-B SCSI Card.
The phone number for Adaptec is 800-959-7274 or 408-945-2550.
[ If anyone sends me info on other scsi controllers, I will include
the info here. ]
==========================================================================
9. How much does it cost to make a CD-ROM?
You can get a master made for about $1300, and then about $1.50 per
disc for duplication. So to make 1000 discs, it will cost you about
($1300 + (1000 * 1.50)) = $2800. Publishers often have `first-timer'
specials with steep discounts off the list price. For instance, DMI
recently had a special of mastering, 50 discs, and two hours of tech
support for $750.
If you only want a few discs, you can have single ISO-9660 `one-offs'
made for about $200 for the first disc, and $100 for additional copies.
==========================================================================
10. I have a great idea for a CD-ROM but no money. What can I do?
You can author a CD-ROM, and have someone else publish it and pay you
royalties. One company that does this is Walnut Creek CDROM. Their
author guidelines are available by anonymous ftp from cdrom.com in the
file /cdrom/author.txt.
==========================================================================
11. Where can I get a CD-ROM published?
I have used both of these companies, and highly recommend either:
Digital Audio Disc Corporation
1800 North Fruitridge Avenue
Terre Haute, IN 47803
812-462-8100, 812-466-9125 FAX

4905 Moores Mill Road
Huntsville, AL 35810
800-433-DISC, 205-859-9042, 205-859-9932 FAX
DADC is a subsidiary of Sony, and DMI is a subsidiary of Philips.
A more detailed list of 25 publishers in 8 countries is available via
anonymous ftp in cdrom.com:/cdrom/publshrs.

13. Where can I get blank media for my CD-ROM recorder?
The blank discs for CD Recorders are not the same as a normal CD. The
metal data surface is gold instead of aluminum. The recorder uses a high
powered laser to modify a dye layer which is between the gold and the
plastic. This dye is somewhat photo sensitive so write once CDs should be
stored in a dark place. They should be stored in an area that does not
rise above 40 Celsius (104 F). It takes about half an hour to burn each
disc.
The blanks come in two sizes. 63 minute, and 74 minute. The time refers
to the amount of digital audio that can be recorded. Since DA is read
from the discs at a constant rate of 150 kb/sec, it is easy to calculate
the amount of data they will hold. The 63' discs will hold about 580 meg,
and the 74' discs will hold about 660 meg.
Here are several sources for blank discs:
DataDisc (1-800-328-2347, 1-703-347-9085 FAX). 74 minute $27 quantity 10.
63 minute $19 quantity 25.
DataWare (1-510-942-3111, ask for Jeff Caplan). 74 minute (650 meg) blanks
for $31 quantity ten, $29 quantity 100, and $27 quantity 500.
Sonic Solutions 415-485-4800. Their April 1992 price list shows CD-R74
quantity 100 as $27.50, CD-R63 quantity 100 as $25.00.
The U.S. sales office for DIC (a Japanese ink and chemical company) can
be reached at 201-224-9344. DIC claims a useful life in excess of
75 years for their discs.
APDC sells blanks discs, magneto-optical disks, 8mm and 4mm tapes.
800-522-7232, ask for Susan Bradley.
Kodak also sells them. Call 800-242-2424.
Mitsui Toatsu: The product name for their disks is Airy. Their
advertising literature claims that the accelerated aging tests
indicate a life of up to 240 years assuming storage at 25C. The Warranty
on the jewel case is for 1 year from date of purchase.
Japan 03-3592-4774
United States 212-867-6330
Germany 211-320458
England 71-976-1180

14. I have 10000 paper documents that I want to put on a CD-ROM. Who can help?
Check the classified ads in the back of CD-ROM Professional Magazine.
There are several companies that will do large scale scanning, OCRing,
and data entry. Because these things are so labor intensive, most of
work is done offshore, usually in Malaysia or India.
-----------------------------------------------------------------------
Agro Computer Systems can process several thousand pages a day,
and claims an error rate of less than 10E-6. For more information
contact
Mr. G. M. Mahindra
Agro Computer Systems
28 Lalbagh (Mission) Road
Bangalore 560 027
India
Phone: +91 812 235083, FAX: +91 812 2241158
-----------------------------------------------------------------------
For smaller jobs that need a quick turn around I have used a company
called "Quick-Set" (+1 510 685-9611) that does data entry, scanning,
and OCRing.
==========================================================================
15. Are there any organizations of CD-ROM Publishers?
The Optical Publishing Association is a non-profit trade and professional
organization for CDROM and other digital media publishers. They have been
around since 1988, publishing newsletters and backgrounders for publishers,
and promoting profitable practices for the business.
OPA, PO Box 21268, Columbus OH 43221 USA, 614/442-8805, 614/442-8815 (fax)
CIS address 71333,1114, 71333.1114@compuserve.com, AppleLink r.bowers.
==========================================================================
16. Where can I get more information about CD-ROM publishing?
Subscribe to CD-ROM Professional Magazine, 1 800 248-8466, $39.95/year
There is a mailing list devoted to CD-ROM publishing. For more information
send a message to Mail-Server@knex.via.mind.org with the word "HELP" in
the body of the email text.
There are several files pertaining to CD-ROM publishing available for
anonymous ftp from cdrom.com.
==========================================================================
17. How much information will fit on a CD-ROM?
It depends on the drive. Almost all CD-ROM drives will handle up to
620 megabytes with no problems. Many newer drives can read discs with
over 700 megs.
The CD-ROM Users Group (see above) has a diagnostic CD-ROM that
will tell you how much information your drive can handle.
==========================================================================
18. Why doesn't MSCDEX work with DOS 5.0?
You must use SETVER with MS-DOS 5.0, to make MSCDEX 2.20 work properly.
Otherwise you will get an incorrect DOS version message. See the MS-DOS
5.0 documentation on how to use SETVER. MSCDEX 2.21 works with MS-DOS 5.0
without SETVER.
==========================================================================
19. Where can I get the latest version of MSCDEX?
Call MS BBS at 206-936-4082. Choose F for file library, S UPDATES, F to
list files, then D MSCDEX.ZIP to download the file. (Microsoft may have
deleted this file.)
You can get the latest version of MSCDEX (2.21) in a self-extracting zip
archive via anonymous ftp from cdrom.com:/cdrom/cdext.exe.
It is also available in the MSL library on CompuServe, as CDEXT.EXE.
==========================================================================
20. I bought a used drive at a garage sale. Where can I find a driver for it?
Many CD-ROM manufacturers maintain BBS's where you might be able to find
drivers for their drives:
NEC BBS: +1 508 635-6328
Philips BBS: +1 310 532-6436
Sony BBS: +1 408 955-5107 or +1 408 372-7426
Pioneer: +1 408 748 2105 (9600/HST/8N1)
==========================================================================
21. What is the difference between `High Sierra' and ISO-9660?
Not much. When the standard was first proposed, it was given the name
"High Sierra'. Later it was adopted as an offical standard, with a few
minor modifications, and was designated ISO-9660. Usually when someone
says "High Sierra", they really mean ISO-9660.

23. What is an HFS disc?
HFS is the Macintosh's Hierarchical Filing System. It is unrelated
to High Sierra and ISO-9660 formats. Most CD-ROMs intended for the
Macintosh are created in the HFS format, since HFS does support the
Mac's resource and data forks and file information.
There are drivers made by AsimWare (AsimCDFS) and Xetec that allows HFS
discs to be read on an Amiga. There is a list of differences that the
drivers contends with, such as non-standard characters and 32 character
filenames (Amiga supports only 30).
------
"New Inside Macintosh: Files" published by Addison-Wesley,
has the most complete description of HFS format.

24. Can you give a short explaination of ISO-9660?
ISO-9660 is an international standard that defines a filesystem for
CD-ROMs. Almost all systems support ISO-9660.
Level one ISO-9660 is similar to an MS-DOS filesystem. Filenames are
limited to eight single-case characters, a dot, and a three character
extension. Filenames cannot contain special characters, (no hyphens,
tildes, equals, or pluses). Only single case letters, numbers, and
underscores. Directory names cannot have the three digit extension,
just eight single-case characters.
All alphabetics are in UPPER case; some software maps this to lower case.
Either the file name or the extension may be empty, but not both ("F."
and ".E" are both legal file names).
There is a "File Version Number" which can range from 1-32767, and is
separated from the extension by a semi-colon. The file version number
is ignored on many systems.
Here are some examples of legal and illegal filenames:
Legal Illegal Why
TEST_1C.TXT TEST-1C.TXT hyphen
TEST1C.TXT TEST 1C.TXT space
TEST.1C TEST.1C.TXT more than 1 period
README Readme not single case
Subdirectories are allowed to nest up to eight levels deep.
Level two ISO-9660 allows longer filenames, up to 32 characters.
But many of the other restrictions still apply. Level two discs
are not usable on some systems, particularly MS-DOS.
==========================================================================
25. What the heck does `Red Book', `Yellow Book', etc. mean?
"Red Book" is the common name of the "Compact Disc Digital Audio
Standard". When a disc conforms to the red book standard, it will
usually have "digital audio" printed below the "disc" logo. Most music
CDs conform to this standard.
"Yellow Book" is the standard for CD-ROM. When a disc conforms to the
yellow book, it will usually say "data storage" beneath the "disc" logo.
"Green Book" is the CD-I (compact disc interactive) standard.
"Orange Book" is the standard for write-once compact discs.
"Blue Book" is the standard for LaserDisc.

26. What is CD-I?
CD-I means "Compact Disc Interactive". It is meant to provide a standard
platform for mass consumer interactive multimedia applications. So it is
more akin to CD-DA, in that it is a full specification for both the
data/code _and_ standalone playback hardware: a CD-I player has a CPU,
RAM, ROM, OS, and audio/video/(MPEG) decoders built into it. Portable
players add an LCD screen and speakers/phonejacks.

==========================================================================
27. What is CD-ROM/XA?
CD-ROM/XA is an extension to the Yellow Book Standard. A track on
a CD-ROM/XA disc can contain computer data, compressed audio data,
and video/picture data. Many CD-ROM drives do not support CD-ROM/XA.
CD-ROM/XA extends CD-ROM by adding some of the CD-I disc features (such
as using Mode 2 tracks with interleaved compressed-audio and other data).
Thus CD-ROM/XA (eXtended Architecture) is often called the "Bridge" format
between CD-ROM and CD-I... though the relationship is mostly the sector
types. CD-ROM/XA applications still require specific code for each target
platform.
----------------------------------------------------------------------
CDROM-XA specifies a `bridge format' so that a CDROM-XA disc can be read
on a CD-I player as well as on a PC under MSCDEX (provided that you use
a conforming (.SYS) driver. On a normal yellow-book CDROM, a data track
contains only mode-1 data sectors. On a CDROM-XA, a (the) data track
contains only mode-2 data sectors. A mode-2 sector can be of two formats,
form-1 and form-2. A form-1 sector contains 2048 bytes of user data,
together with EDC and ECC bytes. A form-2 sector contains 2324 bytes of
raw data (e.g. ADPCM audio or video data). If the device driver delivers
2048 bytes of data when MSCDEX asks for it, regardless whether the sector
is mode-1 or mode-2/form-1, the PC is CDROM-XA compatible.
==========================================================================
28. What are the Rock Ridge extensions?
The Rock Ridge extensions use some undefined fields in the ISO-9660 standard
to allow full unix-like filenames, symbolic links, and deep directories.
"Rock Ridge" is named after the town in the movie "Blazing Saddles" for no
particular reason.
To receive a copy of the current version of the Rock Ridge specifications,
please contact Bob Niland, e-mail rjn@fc.hp.com, fax 303 229 4545. You
can ftp the Rock Ridge specs from cdrom.com: /cdrom/rockridge.

Rock Ridge is expected to be approved as an ISO standard during the first
quarter of 1993.
==========================================================================
29. What is ECMA 168?
ECMA 168 is a volume and file format standard for write-once CD and CD-ROM.
It was approved as a European standard by the ECMA General Assembly in June
of 1992. It provides for full Orange Book functionality, including
multisession recording, track-at-once recording, and packet recording.
When used with an Orange Book writer, this will allow write-once CD to
be used more like a general-purpose storage peripheral than is possible
using ISO 9660. ECMA 168 also incorporates the functionality of Rock Ridge:
the ability to use Unix-style filenames, Unix permissions, and deep directory
hierarchies. Much thought was put into character set issues, and ECMA 168
accommodates multiple-byte character sets such as ISO 10646. Although
ECMA 168 is not upward-compatible with ISO 9660, it is possible to write
a "conformant disc" containing both sets of volume and file structures.
If such a disc is Yellow Book compatible (a CD-ROM or a CD-WO written
disc-at-once), it could be read on either an ISO 9660 system or an ECMA
168 system. There are many common elements between ECMA 168 and ECMA
167, which is a new standard intended primarily for WORM and erasable
optical disks. Hopefully this will encourage developers to support both
standards.
The title of the standard is "Volume and File Structure of Read-Only and
Write-Once Compact Disc Media for Information Interchange". This standard
expands upon the ISO-9660 CD-ROM standard.
At the current time, I do not know of any companies which support ECMA 168
in their products.
A new draft international standard on CD-ROM/CD-WO format:
ISO/IEC DIS 13490 Volume and File Structure of Read-only
and Write-once Compact Disc Media for Information Interchange
is currently undergoing letter ballot process and voting may
end at end of August, 1993.
DIS 13490 is also the ECMA Standard 168, which is derived from
the Frankfurt Group proposal. Copies of this draft standard
should be available at the ANSI or ECMA office.
DIS 13490 is designed to support both the CD-ROM (yellow book) and
CD-WO (orange book) conforming media. In addition, DIS 13490 removed
many unnecessary restrictions of ISO 9660, and is compatible
with ISO 9660 at the directory and file structures level.
DIS 13490 conforming discs can also be made to be read
by both ISO 9660 and DIS 13490 conforming receiving systems.
==========================================================================
30. Is a short technical introduction to these standards available?
The file ftp.apple.com(130.43.2.3): /pub/cd-rom/cd-rom.summary gives
a short techie introduction to compact disc technology.
----
There is a good short general article on CD-Rom and its's many
variations (CD-XA, CD-I, CDTV, PhotoCD) called MULTIMEDIA IN A MUDDLE
by Barry Fox in the New Scientist (London, ISSN# 0262-4079) vol. 131
no. 1787 (Sep 21, 1991) pp.35-38
----
There is a very good article by Bill and Lynne Jolitz "Inside the
ISO-9660 Filesystem Format" in the December 1992 Dr. Dobbs Journal.
Detailed source code examples are provided. They are planning followup
articles covering Rock Ridge, CDI and CDROM-XA.
----
The SAMS book "Principles of Digital Audio" by Ken C. Pohlmann (ISBN
0-672-22634-0) deals primarily with audio CDs but there are sections
dealing with CD-ROM, CD-I, DVI, CD-V, CD-WO, Erasable CD, CD + G and
CD + MIDI.
----
There is a good brief explaination of all these standards in the paper
"Compact Disc Terminology"
Nancy Klocko
Disc Manufacturing Inc.
1409 Foulk Road, Suite 202
Wilmington, DE 19803
1-800-433-DISC
Here is some information from the paper:
Standards:
Red Book == CD-Audio
Yellow Book == CD-ROM
Mode-1 is for computer data
Mode-2 is for compressed audio data and video/picture data
CD-ROM/XA == an EXTENSION to Yellow Book and defines a new type of track.
CD-ROM Mode 2, XA Format, is used for computer data, compressed audio
data, and video/picture data. A CD-ROM / XA track may interleave Mode 2
compressed audio and Mode 2 data sectors. Additional hardware is needed
to separate these when playing the disc. The hardware is programmed to
separate the audio from the data, decompress the audio and play it out
through the audio jacks. At the same time, the hardware passes the data
to the computer.
NOTE: Additional hardware is needed to play a CD-ROM / XA disc. Several
vendors offer an XA interface board that will allow an existing CD-ROM
drive to play CD-ROM / XA discs.
Green Book == Compact Disc Interactive (CD-I)
Orange Book == Recordable Compact disc Standard
Part I - CD-MO (Magneto Optical)
Consists of optional Pre-Mastered (READ-ONLY) area and a Recordable
(re-writable) user area.
Part II - CD-WO (Write Once)
Orange Book Part II also defines a second type of CD-WO disk called
a "Hybrid Disc". This disc consists of a Pre-recorded Area and a
Recordable Area. The Pre-recorded area is a READ ONLY area where
the information is manufactured into the disc. (This area is written
per the Red, Yellow, and Green Book specifications, and can be played
on any CD-Player.) The Recordable areas are where additional
recordings can be made in one or more sessions. Only the first
session on the disc is readable by todays CD-Players; additional
software will be needed to read the additional sessions.
A TOC (Table of Contents) is written during each recording session.
Disc will have multiple TOCs, one for each recording session.
Photo-CD is an example of a "Hybrid Disc".
CD-Bridge Disc
The CD-Bridge Disc defines a way to add additional information in
a CD-ROM / XA track in order to allow the track to be played on a
CD-I player. the result is a disc that can be played on both a
CD-I player connected to a TV set and on a CD-ROM / XA player
connected to a computer.
An example of a CD-Bridge Disc is the new Photo-CD disc. The
Photo-CD disc will be playable in CD-I players, Kodak's Photo CD
players and in computers using CD-ROM/XA drives.
Photo-CD
The Photo CDs will be Mode 2 Form 1 sectors per the CD-ROM / XA
specifications. The disc will be written per the Orange Book Part
II "Hybrid Disc" specifications. This will allow photographs to be
written to the disc in several different sessions. Additionally,
the disc will use the CD-Bridge disc format to allow the disc to be
readable by both CD-I and CD-ROM / XA players.
The photographs written to the disc in the first session will use
the ISO 9660 format. These photographs will be readable with the
existing CD-ROM / XA players connected to a computer running new
software written for the Photo CD picture structure. Additionally,
the photographs will be displayable on CD-I Players and Photo CD
Players connected to a TV set.
Photographs written to disc after the first session will be
displayable on CD-I Players and Photo CD players. New software
and/or firmware will be needed to read these additional photographs
with existing CD-ROM/XA players.
==========================================================================
31. Who comes up with these standards? Can I have any input to the process?
In the case of the colored books, they have been developed by engineers
within Philips and Sony. Few people outside these companies have input into
the process.
The file format standards (ISO 9660, Rock Ridge, and ECMA 168) have all
been developed originally by ad-hoc groups of interested people from
various companies in the industry, then have been submitted to established
standards organizations (ECMA, ANSI, ISO) for further work there.
The CD-ROM Architecture Working Group is an official Standards working
Group under the auspices of the IEEE Computer Society by way of the
Standards Committee for Optical Disks and Multimedia Platforms (SCODMP)
chaired and sponsored by Dr. Lawrence Welsch, PhD. Mike Rubinfeld is
presently the Chair of the working group. They are working in accordance
with a Project Authorization Request (PAR) for the development of a CD-ROM
architecture profile that hopefully will be made into an international
standard. The PAR was approved by the Standards Activity Board (SAB) of
the IEEE/CS last June and the Architecture Profile will probably be ready
for balloting by August, 1993.

32. Are there any ftp sites with good stuff related to CD-ROMs?
A couple of sites with cdrom related stuff are
cdrom.com (192.153.46.254): /cdrom [ This site is maintained by me. ]
cs.uwp.edu (131.210.1.4): /pub/cdrom
==========================================================================
33. How do I write an MSDOS program that can access a cdrom using MSCDEX?
The MSCDEX interface documentation is available on the Microsoft Programmer's
Library CD-ROM. This also has detailed specifications for drivers that talk
to MSCDEX. It even provides solutions to a number of sticky problems.
The file mscdex21.zip contains Microsoft's info on how to talk to the
CD-ROM extensions (MSCDEX.EXE) and a sample DOS application which is crude
but effective in playing audio tracks. This file is available via
anonymous ftp from ftp.cica.indiana.edu:/pub/pc/win3/uploads/mscdex21.zip
or cdrom.com:/cdrom/mscdex21.zip.
MSCDEX programming information can be found in INTER31?.ZIP. Ralf Brown's
interrupt bible. The information is very complete. The interrupt list
is available via anonymous ftp from Simtel20 (wsmr-simtel20.army.mil) or
from the mirror site wuarchive.wustl.edu: /mirrors/msdos/info/inter31?.zip.
There is a book by Ray Duncan (Microsoft Press) detailing all extensions
to Dos (XMS, LIM EMS, MSCDEX etc..) which should be available in book
stores. The title is "MS-DOS EXTENSIONS" ISBN 1-55615-212-4.
==========================================================================
34. How do I mount an ISO-9660 disc on a Sun?
Su to root and run this command,
# mount -r -t hsfs /dev/sr0 /cdrom
or even better, put the following line in your /etc/fstab
/dev/sr0 /cdrom hsfs ro 0 0
and then run
# mount /cdrom
Don Trimmer, of Delta Microsystems, has written a program that allows
safe mount/umount operations without requiring super user permissions.
You can get his program by anonymous ftp from cdrom.com:/cdrom/mount.c
==========================================================================
35. How do I use a cdrom with OS/2?
What you need to do to make your cdrom drive work under os/2 is:
1) make a bootable msdos floppy disk which is configured so that
you can use the cdrom after booting from this floppy.
2) copy the files fsaccess.sys and fsfilter.sys onto the floppy and
then add DEVICE= statements to the CONFIG.SYS for the floppy.
3) copy the floppy disk to the os/2 hard disk using the VDISK command.
4) create an icon with the "boot from drive" option set to the name
of the file created by the VDISK command.
5) Click on the icon.
-----
OS/2 has builtin support for IBM drives, and for SCSI third party
drives. The Sony CDU 541 works well.
What you need to do if you don't have one of the supported drives, is
use the OS/2 command VMDISK to create a bootable "diskette image" on your
hard disk. On the diskette image file, you will copy a CONFIG.SYS file,
an AUTOEXEC.BAT, and the drivers you require for your CDROM. This feature
allows you use any driver with OS/2. The down side is that you can't
access the device in the image box from any OS/2 window. You have to use
the bootable image box to copy files back and forth between the image box
and any other. If you have one of the supported drives, you can access it
from any box.
-------
The VMDISK technique is only needed for unsupported, mainly non-SCSI
drives. Some unsupported SCSI drives, such as the NEC CDR-84, work
fine with OS/2
The only thing to do in order to make some unsupported SCSI CD-ROM
drives work (as a data CD-ROM, MM is another problem) is to patch the
vendor ID string into \OS2\CDROM.SYS. Simply replace "TOSHIBA " by
"NEC ", etc. i.e. with blank-padding to eight characters. This is
known to work with NEC and SONY drives. It does not work with some
Matsushita (Panasonic) drives.
-------
Systems Integration Technologies sells a Mitsumi CD-ROM Device Driver
for OS/2. The price is $10+S/H for text only, and $25+S/H for the
future enhanced driver. Contact joec@cybernet.cse.fau.edu or

37. How do I read an audio cd track as digital data?
Most CD-ROM drives cannot decode audio information. There are
firmware and data path reasons why it doesn't work. The drive
vendors could make drives that allow this feature.
There are only a few drives with the capability to read audio
tracks as data: The AppleCD 300 (which is a Sony 8003), the Sony
CDU-561 and the CD-ROM drive sold by Silicon Graphics for use
with their Indigo workstation. The SGI drive is a modified
Toshiba 3301B.
For the Toshiba drives, you issue a MODE SELECT command with density
code 0x82 and then all read's with an lba inside a digital audio track
will return 2352 bytes audio samples / block.
Both Sony and Toshiba may support reading audio (red book) CD's on their
next generation drives (the dual speed ones), at least, as an option.
There are several ways to read digital audio from Sony CDU 561
and Sony CDU 8003 mechanisms. Note that the technique of merely
setting the density (0x82) using MODE SELECT SCSI command as on
Toshiba 3401s will not work.
Here are three ways to read digital audio Red Book standard
audio track data across the SCSI bus into your computer complete
with all sound processing already performed (For example the
CIRC routine already run and the output is LRLRLR pairs of 16
bit digital audio samples 2352 bytes per CD-ROM block.
Method 1 : READ CD-DA scsi command 0xD8
Byte 0: D8
1: <LUN stuff> 0
2: <4th most significant byte of logical block address>
3: <3rd byte>
4: <2nd>
5: <1st, lowest of the address>
6: <4th most significant byte of transfer length
7: <3rd byte>
8: <2nd>
9: <1st, lowest of the number of contiguos blocks to transfer>
10: <special sub code selector> (0 == normal 2352, other values
are 01, 02, 03)
11: <control>
Method 2 : READ CD-DA MSF scsi command 0xD9
byte 0: D9
1: <LUN stuff> 0
2: 0
3: <starting minute in binary not BCD>
4: <starting second in binary not BCD>
5: <starting frame (75th of a second) in binary not BCD>
6: 0
7: <ending minute in binary not BCD>
8: <ending second in binary not BCD>
9: <ending frame (75th of a second) in binary not BCD>
10: <special sub code selector> (0 == normal 2352 each, other
values are 01, 02, 03)
11: <control>
For this one you will need to remember how to convert MSF to
logical (LBA) address to set the SCSI transfer length correctly
to avoid the Mac SCSI manager reporting a phase error. to
calculate the number of bytes total you will get use the formula:
((Me-Ms)*60*75 + (Se-Ss) * 75 + (Fe-Fs)) * (2352)
Method 3 : MODE SELECT (6) 0x15
This is a very complex topic to discuss, but if you know how to
use the SCSI mode select page commands the third more direct
(and jitter filled) method to get digital audio across the SCSI
bus on the new SONY devices is to set the block length of the
volatile settings in the 6th 7th and 8th bytes of the Block
descriptor section of a MODE select list with 0 or more pages
(12 bytes for none) to a setting of either 2352, 2368, or 2448.
You want 2352, but I have not tried this technique and Sony
recommends the special streaming commands.
WARNING: for high quality use large transfers but QUICKLY
reissue another command as soon as a command is completed. The
head must never come to a rest for 100% pure results.
-------
The format of a CD-DA sector, that the Toshiba XM-3401 returns, is not
too complicated: each sector contains 2352 bytes, these are devided
into 588 16-bit signed stereo samples of 4 bytes each. The 16-bit
samples are returned in 'low byte first' (i386, ...) byte order. The
16-bit samples in the sector are intended alternating for the left and
right channel, starting with the left channel.
struct cdda_sector {
struct cdda_sample {
char left_channel_lsb;
char left_channel_msb;
char right_channel_lsb;
char right_channel_msb;
} samples[588];
};

38. Why do CD-ROMs cost so much?
Here are several answers, take your pick:
A. Because too many people are willing to pay the high prices.
B. They are not really very expensive when you consider how much data
they contain. Even the most expensive CD-ROMs are often cheaper
than the least expensive floppies when you figure the cost per byte.
C. Because there isn't enough competition. The prices will come down
when more people buy drives, and more CD-ROM titles are available.

39. Why do all the bundle deals require me to buy a drive? What if I
already have a drive?
Many disc producers sell outdated or surplus discs at steep discounts
to be bundled with new drives. The theory is that the new drive owner
will find the discs useful, and order the latest version at full price.
There are some bundle deals that do not require you to buy a new drive.
For instance, the CD-ROM User's Group (see above) has a bundle of ten
discs for $99.
==========================================================================
40. Are alt.cd-rom archives available anywhere?
I don't know if there is an ftp site anywhere that archives alt.cd-rom,
but you can retrieve old articles via email:
For a list of files available, send the message
INDEX CDROM-L
as the first line of your e-mail message to:
LISTSERV@UCCVMA.BITNET
or the Internet form of address:
LISTSERV@UCCVMA.UCOP.EDU
To retrieve an archived message, send the e-mail message
GET CDROM-L LOGyymm
or SENDME CDROM-L LOGyymm as above
where yymm is the year and month of the archive wanted.
e.g. LOG9110 = Log of October 91 messages.
==========================================================================
41. What is the shelf-life of a CD-ROM?
If a CD-ROM is not manufactured properly, the lifetime can be very
short, perhaps only a few years. This can happen if the edge of the
disc is not properly sealed, and oxygen reaches the metal surface.
If the disc is manufactured properly, it will last a very long time.
Most CD-ROMs should last for more than a human lifetime.
Philips has proposed new standards for testing CD-ROMs that are expected
to result in discs that will enjoy a life span of more than a thousand
years. For more information see Fox, Barry "CD Makers Perform in Unison
to Stop the Rot" New Scientist 134(1815) (April 4, 1992):19.
The laser used in a CD-ROM drive is very low power, and does not
harm the disc in any way. Reading the disc will not shorten
the lifetime.
==========================================================================
42. How should I handle my CD-ROMs? How do I clean them?
The following guidelines represent the current thinking for the care
and handling of CD-ROM discs, by a number of CD-ROM disc and drive
manufacturers. The validity and usefulness of most of these
guidelines have not been substantiated by government testing and
therefore are presented for information only.
Wash your hands before contact with the disc. If available, wear
lint-free cloth gloves, finger cots, or talc-free latex gloves.
If you must wipe the disc, do so with a soft, dry, lint-free cloth in
a radial motion- that is from the inner to the outer hub- not in a
circular motion around the disc like you might do for a phonograph
record. The most devastating scratches are those which occur along a
circular arc of the disc which can obscure a long stream of pits.
Certain cleaning agents and solvents can damage the discs. Some of
these include: gasoline, paint thinners, benzine, acetone, carbon
tetrachloride, chlorinated cleaning solvents, ammonia, and household
detergents which contain ammonia. Do not clean with a water soaked
cloth. The use of Isopropyl alcohol, the ingredient in many
commercial CD cleaning products, as well as certain waxes and acrylic
liquids, is still questionable.
Do not clean the label side of the disc.
Use of a CD-ROM caddy is highly recommended during transport and
operation. Limit the amount of physical contact with the disc.
Always handle the disc by the outer edge and/or the inner (hole) edge.
Never touch the data surface.
Discs like to "live" in the same conditions that people do; that is:
They don't like to be manhandled
They don't like exposure to temperature extremes
They don't like exposure to excess humidity
They don't like exposure to high intensity UV light

43. Which drives will work with Kodak Photo CD?
According to Kodak, the following drives are compatible. To view more
than just the first recorded session, you need a multisession drive.
Most of these drives are single session only.
Magnavox CDD461 - single session
CDD462RS - multi session
Sony CDU-6205 - single session
CDU-535 - single session
CDU-561 - multi session
NEC CDR-73 - single session
CDR-37 - single session
Apple 300CD - multi session
The NEC CDR-74/84 works fine with PhotoCD. Older models that have a
firmware revision of 1.0 should be sent back to NEC for a FREE refit,
that upgrades the firmware to 1.0a, and may update some other components.
NEC should be called at 1-(800)-388-8888 follow the recorded messages to
get them to sent the info required for the refit (or hit 6 then 1 to get
there instantly). You will get your drive back in 3-4 business days.
The Kodak Information Center is maintaining a file on the compuserve CDROM
forum of compatible drives, and it has become quite extensive. They also
specify compatible SCSI boards, drivers, and cable configurations. There
are also a couple of subtle issues in compatibility that are still being
worked out. For example, the NEC drives are single session compatible, but
not multi. There are also drives which have been certified as compatible
which are not XA, and there is some indication that this makes them useful
for pictures alone, but not for mixed media Photo-CD productions in the
future.
==========================================================================
44. What is a multisession CD drive?
A CD has an "index" area which contains track details; this is what is
read when you first stick an audio CD into a player. Photo-CDs have a
separate index area each time they are written (because it is impossible
to "update" the index area). A multisession drive is one that knows to
look for multiple index areas. The full details are contained in the
Philips/Sony/Kodak "Orange Book" standard for writable CDs.
==========================================================================
45. How does Photo CD work?
In a nut shell, 35mm film (negative, slide, B&W, internegative) is scanned
by an image scanner and transfered to XA-formatted CD-ROM discs. These
discs are manufactured by burning (writing) -- not by pressing.
Each scanned image on the disc is kept in five resolutions. These five
resolutions are called: Base/16, Base/4, Base, 4Base, and 16Base. As
examples, Base/16 is one sixteenth the resolution of the "Base" image, and
16Base is sixteen times the resolution of "Base". (These are not simply
larger picture elements. There are in increased number of scan lines.)
The 4Base and 16Base images are are compressed using Huffman encoding. You
need the decompression software to pull the higher resolutions out of the
image. You would typically need these higher resolutions if you want
enlargements or if you intend to use an HDTV as a display device.
==========================================================================
46. Where can I get some information about the Kodak Photo CD?
To learn more about Photo CD products or other KODAK desktop color
imaging products, contact Eastman Kodak Company at 1-800-242-2424 Ext 51
or 716-724-1021, ext. 53.
Or send inquiries to the following address:

Information about PhotoCD is available by anonymous ftp from
cdrom.com:/cdrom/photo_cd.
There is an excellent article on PhotoCD in the Sept 92 issue of
Photographic Magazine.
Eastman Kodak Co recently released Photo CD Access, which is designed
to allow users to integrate CD images into any Windows or Macintosh
Application. Requires a CD ROM XA (Extended Architecture) drive.
Most popular image formats are supported, including TIFF, GIF, TARGA
and PICT. Kodak sells the software directly. $39.95, 1-800-242-2424.
A developer's kit is available for $695 and includes source code as well
as object for PC/MAC.

47. Where can I get maps of the US on CD-ROM?
The USGS is producing a series of cds that contain 1:100,000 scale
digital line graph (DLG) data. Presently, only Florida is available.
Also, 1:2,000,000 DLG cd is available for the US. Call 1-800-USA-MAPS
for more info.
You can also get topo data (with AVHRR coverage) on CD-ROM for $32. This
is DEM (30" elevation data) for the whole US. Contact: EROS Data Center,
Sioux Falls, SD 605-594-6507, or 6511
The Digital Chart of the World (DCW), produced by your Defense Mapping
Agency, is generally acknowledged to be the best data set providing
world-wide coverage. It is at a scale of about 1:1 000 000, and it is
unlikely that you will find data at a larger scale for much of the world.
At $200.00 for the set of 4 CD-ROMs and viewing data, it is considered to
be a steal by most professional users, though it might be a bit of an
overkill for domestic use. You can obtain it from:
U S Geological Survey

50. Can I speed up my CD-ROM by using a cache?
There are several programs that cache information from the CD-ROM onto
your hard disk. Since magnetic discs are often more than 10 times faster
than a CD-ROM, this can result in dramatic improvements under some
circumstances.
Most of the programs cache the directory information, so you can traverse
subdirectories quickly. They also cache the most recently accessed blocks
of data. So if you use the same files over and over, or access the same
records in a database, your CD-ROM will seem much faster. But when you
access the information for the first time, it will be just as slow as
ever.
SpeedCache+ from Future Systems has been recommended as a pretty good
caching program.
Future Systems, Inc
0420 South 500 East
Bluffton, IN 46714
(219) 824-4963
------
On the Macintosh a prescanning (Directory, file atrributes, icons, etc)
cache to accelerate the Mac with CD-ROMs exists from two companies
SpeedyCD 1.22 and FWB CD-ROM ToolKit 1.0. FWB seems much faster than
SpeedyCD and can prescan any type of CD-ROM volumes (ProDos, Mac HFS,
MS DOS, ISO9660, PhotoCD etc.) It prescans in the background.

54. How do I put a CD-ROM Drive on a Ethernet by using a unix system
(e.g. a SUN ) as a server and PCs as clients.
Edmund J. Sutcliffe <edmund@york.ac.uk> writes:
If you mount an ISO format CD-ROM on you sun using the commands previously
mentioned in Question 34 and export it to the network using
# exportfs /cdrom
It is then made available for mounting using NFS to other devices.
The PC can mount the CD-ROM using any NFS Client including Sun's PC-NFS.
(This is the product we use) Most PC search software requires the presence
of MSCDEX to work with the CD-ROM. Daniel Churchman of Digital Solutions
Pty Ltd, of Queensland Australia wrote a simplistic MSCDEX faker called
MXSUB in May 1990 which they release under GNU Public License in January '92.
This work well with early versions of the search software.Colin Ian King
<cik@ukc.ac.uk> wrote a small quantitiy of C code which fakes the MSCDEX
extensions required by many PC packages. He also produced a list of which
search software used which MSCDEX functions. This code is released under
GNU Public license and is available from ftp.york.ac.uk in /pub/cd-rom,
via anonymous FTP. This faker can work with an Microsoft Compatible Network
which can see CD-ROMs.
It is also necessary sometimes to set the volume label of the NFS mounted
drive. "Malcolm E. Sherrington" <msherri@rpms.ac.uk> in an article in the
proceeding of the UKUUG confernce of January '93 talks about the problems
in doing this. He wrote a program call NFSLABEL to label PC-NFS mounted
Network Drives. However, this code was slow to be release and Robert
Turner <Robert.Turner@brunel.ac.uk> wrote similar code called LABELNFS
which is available in source form. All this code is available from
ftp.york.ac.uk in /pub/pc-nfs. This code has been sucessfully used with
BRS/Search SilverPlatter and WilsonDisk search software.
The only CD-ROM search software which has been made available to me for
testing purpose, on the Macintosh is SilverPlatters SPIRS. We have a
GatorCS/Rack running GatorShare, an Apple Filing Protocol to NFS convert.
(For more info mail support@cayman.com) This allows the Macs to see NFS
file store as Appleshare Volumes. To mount CD-ROM to the Mac you must do
the following:
1) mount the CD-ROM on a Mac using a local CD-ROM. This
will give you the Volume Name of the CD-ROM as seen to the Mac.
2) mount the CD-ROM on the NFS server.
3) Using GatorKeeper, the management software for GatorShare create a
new AppleShare Volume called the same name as the volume when the
CD-ROM was mounted locally.
This volume should mount the CD-ROM exported from the NFS server but the
DESKTOP file should be create on some other section of NFS disk as it
cannot be created on the CD-ROM. GatorKeeper will confirm the volume
creation and then uses can mount the Volumes using the Chooser as usual.
The user community can now mount the CD-ROM over the network to their Mac
just like any other network volume and the SPIRS search software can us it.
It is possible to Automate this mount and search software to make it
transparent to the user and so limit usuage.
It should be noted that it is important to license approriately copies
of the CD-ROMs before exporting them generally over the network. You might
also want to restrict access to appropriate netgroups. Also license
locking the search software satisfies certain companies, but not all.
