HELP-OS/2
MAY 1993
This help file contains troubleshooting tips to help you get your CD-ROM up
and running under OS/2 2.1. It also contains notes on how to use your
Hitachi CD-ROM drive if you have not yet upgraded from OS/2 2.0 to OS/2 2.1.
This help file covers the following models:
External: CDR1503S CDR1700S CDR1900S
Internal: CDR3500 CDR3600 CDR3700 CDR6700
Amdek Drives: LD-1 LD-2
Note: The CD-ROM drive model number is located either on the back or bottom
of the drive.
If you have followed all of the tips listed in this file and are still NOT
able to obtain a directory of the CD-ROM disc, please contact your dealer.
I. SET UP
Make sure you have connected your CD-ROM drive to your computer and
have used the DDINSTAL program supplied with OS/2 to install the files
located on the CDREXT5D diskette. Also make sure you have a CD-ROM
disc (label side up) in the CD-ROM drive.
NOTE: IF YOU ARE USING THIS SOFTWARE TO UPDATE YOUR DEVICE DRIVER
OR CHANGE YOUR I/O ADDRESS, THE EXISTING HITACHI CD-ROM DEVICE
DRIVER LINE MUST BE DELETED FROM YOUR CONFIG.SYS FILE BEFORE
RUNNING THE DDINSTAL PROGRAM.
The DDINSTAL program adds one line to your CONFIG.SYS file if it is not
already there. Make sure the lines of your CONFIG.SYS file resemble the
following examples. (Note: The following is a "simple" example for OS/2
2.1; your file may differ. Please refer to the "INSTRUCTION MANUAL for
CD-ROM DISK" for more information.) You can look at the contents of
the CONFIG.SYS file by using the TYPE command from a command line session.
Please consult your OS/2 Command Reference for further instructions.
The OS2CDROM.DMD program will automatically assign the CD-ROM drive to the
next available drive letter. For instance, if you have a hard drive "C",
a 3-1/2" floppy drive "A" and a 5-1/4" floppy drive "B", the next available
drive letter is "D" and will be assigned to your CD-ROM drive.
C:\>TYPE CONFIG.SYS
BASEDEV=OS2DASD.DMD
BASEDEV=HITCDISA.ADD /P:300 <---new*
IFS=\OS2\CDFS.IFS /Q
DEVICE=\OS2\OS2CDROM.DMD
DEVICE=\OS2\MDOS\VCDROM.SYS
* <OR> BASEDEV=HITCDMC.ADD <---new
II. DETERMINE THE PROBLEM
If your CD-ROM drive is not properly connected and powered on at boot time,
the following messages will appear on the screen after the multi-colored
OS/2 screen goes away but before the OS/2 desktop appears:
(HITCDISA.ADD) ERROR: No CD-ROM devices found
SYS1201: The device driver "HITCDISA.ADD" specified in the BASEDEV= command
on line xx of the CONFIG.SYS file was not installed. Line xx
is ignored.
Press Enter to continue.
If you get this message, go to step III to determine the cause. If you want
to continue to boot OS/2, but without the CD-ROM drive support, press Enter.
If you got the message above and there are no other CD-ROM drives installed,
you will see this message:
SYS1201: The device driver "OS2CDROM.DMD" specified in the DEVICE= command
on line xx of the CONFIG.SYS file was not installed. Line xx
is ignored.
Press Enter to continue.
The OS2CDROM.DMD module cannot load unless HITCDISA.ADD or some other CD-ROM
.ADD file loads successfully.
If you see the message about OS2CDROM.DMD without the message about
HITCDISA.ADD, check the BASEDEV=HITCDISA.ADD line in the CONFIG.SYS file.
NOTE: OS/2 2.1 will install with a /Q parameter (Quiet) on the line:
DEVICE=\OS2\OS2CDROM.DMD /Q
Remove the /Q if you are having trouble, since the message about
OS2CDROM.DMD will not appear if the /Q is present.
Once you have fixed the problem so that neither of these messages appears,
OS/2 will boot with CD-ROM support.
At this point the CD-ROM drive has been installed successfully.
To verify this, open a DOS session or an OS/2 command line session
and try to obtain a directory of the CD-ROM disc:
At the C:\> or [C:\], type in the CD-ROM drive letter.
C:\>D:
D:>DIR
The following message indicates that there is no disc in the drive:
DOS Full Screen or OS/2 Full Screen
SYS0039: The D: device is not ready.
Return error code to program
End program/command/operation
Retry command or operation
Display help
Insert a disc and select "Retry command or operation" or select
"End program/command/operation" to return to the prompt without a disc.
If you see the following message, it indicates that either you have
specified the wrong drive letter for your directory request, or that
the CD-ROM drive has not been installed:
SYS0015: The system cannot find the drive specified.
In the latter case, recheck the beginning of this step II above and
step III below.
If you get a directory listing of the files on the CD-ROM disc, you have
successfully installed your CD-ROM drive. Please consult any instruction
manual that came with your CD-ROM application for instructions on
installing the application.
III. SYS1201 ERROR
A. Drive Not Properly Connected
1. Check that the drive cable is firmly connected to the drive
and to the interface card.
2. Check that the interface card is fully seated and secured
in the computer.
B. Wrong Device Driver
1. Type your CONFIG.SYS file to the screen by entering the
following at the C:\> or [C:\]
C:\>TYPE CONFIG.SYS
2. On the BASEDEV= line, which device driver do you have
loaded, HITCDISA.ADD or HITCDMC.ADD?
HITCDISA.ADD is for ISA/EISA bus compatible computers
including IBM PC/XT/AT, PS/1 series,
ValuePoint series and PS/2 Models 25-40
HITCDMC.ADD is for Micro Channel computers including
IBM PS/2 Models 50-95 and compatibles
3. Make sure you have selected the correct device driver for
your computer type. If you have selected the correct
driver, skip to Step C. If not...
4. Load your CONFIG.SYS file into an editor program such as
EDLIN or the OS/2 System Editor.
5. Edit the device driver line so that the correct device driver
is loaded, either HITCDISA.ADD or HITCDMC.ADD.
6. Save the edited CONFIG.SYS file.
7. Insert the CDREXT5D disk into your A (or floppy) drive. Copy
the correct device driver into the OS2 subdirectory:
C:\>COPY A:HITCDISA.ADD C:\OS2\*.*
<OR>
C:\>COPY A:HITCDMC.ADD C:\OS2\*.*
8. Reboot the computer system (Ctrl+Alt+Del). Return to step
II. (NOTE: You can reboot from the SYS1201 message, but
if you have actually brought up the OS/2 Desktop, you should
Shutdown before rebooting.)
C. Wrong Drive ID
1. On the back of your CD-ROM drive are dip switches
(except for drive model CDR1503S).
2. Make sure the Drive ID is set to drive ID 0. If it is, skip
to step C.
CDR6700, CDR3700, CDR1700S, CDR3600:
Set switches #1 & #5 UP and the rest DOWN.
CDR1900S: Set switches #1 & #5 to the RIGHT and the
rest to the LEFT.
CDR1503S: Set the screwdriver-type switch to Drive ID 0.
CDR3500: Set switch #1 UP and the rest DOWN.
Note: For multiple drives, the first drive must be set
to drive ID 0, the second to drive ID 1, etc.
Please consult your drive's instruction manual
for drive ID settings beyond drive ID 0.
3. If you had to fix the Drive ID setting, reboot the computer
system (Ctrl+Alt+Del). Return to step II.
D. I/O Address Conflict
1. If you are using an ISA/EISA bus compatible computer
including IBM PC/XT/AT, PS/1 series, ValuePoint series
and PS/2 Models 25-40, you may have an I/O address conflict.
2. Turn your computer off, open the CPU and locate the CD-
ROM Interface Card connected to your CD-ROM drive and
remove it.
3. Verify that the jumper on the CD-ROM interface card is set
to address 300 (position S4).
4. Verify that the /P: parameter of the device driver line in
the CONFIG.SYS file is set to address 300:
BASEDEV=HITCDISA.ADD /P:300
5. If steps 2 and 3 check out okay, your computer may already
be using address 300 for some other device.
6. Move the jumper on the CD-ROM interface card to address
360 (position S7). The following chart lists address settings
from the top edge of the card down. The model number of
the CD-ROM interface card is stamped on your card.
CDIFI8S, CDIFI8A, CDIFI4A CDIF35A, CDIF25A3
360 S7 200 S0
340 S6 220 S1
320 S5 240 S2
300 S4 (default) 260 S3
260 S3 300 S4 (default)
240 S2 320 S5
220 S1 340 S6
200 S0 360 S7
7. Reinstall your CD-ROM interface card, connect any cables,
and turn your computer on.
8. Load your CONFIG.SYS file into an editor program such as
EDLIN or the OS/2 System Editor.
9. Modify the device driver line to reflect the address change:
BASEDEV=HITCDISA.ADD /P:360
10. Save the edited CONFIG.SYS file.
11. Reboot the computer system (Ctrl+Alt+Del).
12. Try to obtain a directory of the CD-ROM disc as in step II.
(Note: Replace your computer cover as soon as you get a
directory.)
13. If you are still getting a SYS1201 error, repeat steps 6-12
trying different address settings in this order: 340, 320,
260, 240, 220, 200.
ADDITIONAL INFORMATION:
A. CONFIG.SYS - Device Driver Parameters
The following is further information on the parameters used in the
device driver line that is added to your CONFIG.SYS file by the DDINSTAL
program:
/P:<address> Specifies the I/O address used by the CD-ROM
interface card. This parameter is optional and only
required if you change the I/O address of the
interface card to an address other than 300. If your
computer is already using address 300, you may
choose an unused address for this parameter but you
must make sure you have set the jumper on the CD-
ROM interface card to the corresponding setting.
(Note: On Micro Channel computers, the I/O address
setting is completely optional since the driver will
recognize the I/O address set by the configuration
menu of your computer's Reference disk. If used,
however, the address in the CONFIG.SYS file must match
the address setting set with the Reference Disk.)
/N:<number> Specifies the Number of CD-ROM drives connected to
your computer. This parameter is optional since the
driver will recognize as many drives as are powered on.
B. HELP WITH AUDIO - Common Questions & Answers
Q: When I play audio CDs, why don't I hear anything from the computer
speakers?
A: Stereo headphones or Amplified speakers need to be plugged into the
headphone jack located on the front of the CD-ROM drive. If you have
an external drive, you may plug Amplified speakers with built-in volume
controls into the RCA-type phono jacks located on the rear of the CD-
ROM drive. (Note: If you are using the front panel headphone jack,
you may use the front panel volume control knob to control volume. If
you are using the rear panel RCA-type jacks, you must have Amplified
speakers with built-in volume controls in order to control the volume.)
Q: I have a sound card with amplified speakers connected. How do I get
the audio CD sound to play through the sound card speakers?
A: Your sound card must be connected to your CD-ROM drive and have: (1)
line input, (2) mixing capability and (3) a mini-stereo cable to connect
the CD-ROM drive to the input jack located on the sound card. Plug
the cable in the headphone jack located on the front of the CD-ROM
drive or if you have an external drive, you may plug the cable into the
RCA-type phono jacks located on the rear panel of the CD-ROM drive
using an appropriate adapter or cable.
From Windows, start an audio CD playing, activate your mixer control
panel (supplied by your sound card manufacturer), and then set the
level controls of the mixer.
From DOS, use the mixing utility supplied with the sound card.
Q: How do I play audio CDs under OS/2?
A: The CDREXT5D diskette includes software to play audio CDs. (Please
refer to the "INSTRUCTION MANUAL for CD-ROM INSTALLATION DISK" for
information on how to use the CDPLAY.BAT, CDMGR.EXE and CDMENU.EXE
files.) The instructions to start CDPLAY in a DOS Full Screen under
OS/2 are the same as for DOS except that you should never press "X"
to exit the menu. Merely switch sessions under OS/2 to continue your
work, while letting the audio software run in the background. If you
do exit the audio software menu, the audio CD will stop playing at the
end of the current track. Control can be resumed by restarting CDPLAY.
C. Hitachi Bus CD-ROM OS/2 Device Driver Installation Procedure
Installation of the Hitachi Bus CD-ROM device driver is done through
the OS/2 system utility for Device Driver Installation called
DDINSTAL.EXE. This utility is supplied by IBM with OS/2 2.x.
(Installation of IBM's generic CD-ROM support, which is required to
use the Hitachi Bus CD-ROM device driver, is done either at initial
OS/2 installation or with the OS/2 Selective Install utility. Please
see your OS/2 Installation Guide for more information.)
To begin, insert the Hitachi CD-ROM Installation floppy diskette
containing the .ADD and .DDP files into a floppy drive.
COMMAND LINE INSTALLATION
1. Change to an OS/2 Full Screen or an OS/2 Window session.
(DDINSTAL.EXE does not operate in a DOS session.)
2. Type DDINSTAL from the [C:\] prompt.
3. Go to step 2 below.
DESKTOP INSTALLATION
1. From the OS/2 Desktop, open the "OS/2 System" icon,
then the "System Setup" icon, then the "Device Driver
Install" icon.
2. Change the source drive, if needed, to the drive containing
the floppy installation diskette, by clicking on "Change..." in
the "Source directory" section.
3. Change the destination drive, if needed, to the drive
containing the OS/2 system files, by clicking on "Change..."
in the "Destination directory" section.
4. When the correct drives are shown, click on "Install...".
5. Next, find the Hitachi bus driver line matching the port
address on the card and the system type (ISA or Micro Channel).
6. Click on the line with the mouse or, after using the arrow
keys, press the SPACE bar to highlight the desired line.
If more than one line gets highlighted, click again to
unhighlight a line until only one line is highlighted.
7. Click the "OK" box.
NOTE: If you did not highlight a line, you will see the message:
No device drivers have been selected.
8. When the "OS/2 Device Driver Installation" window
reappears, click "Exit".
9. When the "Exit the program." question appears, click "Yes".
10. When the message appears indicating that changes have
been made, and that a shutdown and restart is needed for
the changes to take effect, click "OK".
11. Close opened windows and applications. From the OS/2 Desktop
click the right mouse button, then select "Shut down...".
12. Continue responding to the shutdown messages as appropriate.
13. Reboot when the Shutdown Completed message appears.
D. HELP FOR INSTALLATION
There are several sources of information about the OS/2
installation process:
From an OS/2 Window or OS/2 Full Screen, type A:HELPOS2.
This will display the HELPOS2.TXT from the Hitachi installation
diskette.
From a DOS Window or DOS Full Screen, type A:HELPOS2.
This will display the HELPOS2.TXT from the Hitachi installation
diskette.
In the OS/2 Device Driver Installation window, click on Help.
This will give simplified help relating to installing a device
driver.
From an OS/2 Command Line, type HELP DDINSTAL and press
ENTER. This gives much more detailed information about using
the DDINSTAL program.
E. TECHNICAL INFORMATION FOR ADVANCED USERS
1. CONFIG.SYS MODIFICATIONS
The following lines should be in the CONFIG.SYS to use Hitachi
Bus drives (CDR-3600/CDR-1700S/CDR-3700) with OS/2 2.1.
BASEDEV=HITCDISA.ADD /P:300 or BASEDEV=HITCDMC.ADD
IFS=\OS2\CDFS.IFS /Q
DEVICE=\OS2\OS2CDROM.DMD
DEVICE=\OS2\MDOS\VCDROM.SYS
2. RULES FOR SPECIFYING FILE NAMES IN OS/2 CONFIG.SYS FILES
In the CONFIG.SYS the lines that have BASEDEV= can not have the
path for the file.
The DEVICE= and IFS= lines do have the path for the file.
3. CHANGING THE PORT ADDRESS WITH THE HITACHI BUS DRIVER
An I/O address parameter may be added to the BASEDEV=HITCDISA.ADD
line. The default is /P:300 if no /P: parameter is given. The
/P:ppp parameter can use any of the valid addresses for the
CD-IFI8-S interface card (200, 220, 240, 260, 300, 320, 340, 360).
The HITCDMC.ADD module for Micro Channel systems will automatically
detect which I/O address the CD-IFI5-A card is using, so no /P:
parameter is necessary for the BASEDEV=HITCDMC.ADD line.
4. OVERRIDING THE NUMBER OF DRIVES ASSIGNED FOR THE HITACHI BUS DRIVER
A number of drives parameter may be added to the BASEDEV=HITCD.ADD
line. This controls the maximum number of drives which will be
scanned. The drives must be powered on at boot time. The default
will be the number of consecutive drives found at boot time up to
8. If a CD-IFI4-A or a CD-IFI5-A interface card is detected, only
a maximum of 4 drives will be scanned. A /N:n parameter will
override the maximum number of drives that will be scanned.
F. INSTALLING IBM'S GENERIC CD-ROM SUPPORT FILES
Depending upon whether the original OS/2 installation installed
any CD-ROM support, you may already have one or more of the
necessary support modules on your hard disk. Look for them
before adding them.
DIR \OS2\CDFS.IFS
DIR \OS2\MDOS\VCDROM.SYS
DIR \OS2\OS2CDROM.DMD
The file dates should be March, 1993 or later.
If these files were not installed as part of the initial OS/2
installation process, they can be installed using the OS/2
Selective Install utility. This process varies depending upon
if you have OS/2 2.1 installed, if you are installing OS/2 2.1
from IBM's CD-ROM installation disc or if you want to upgrade
from OS/2 2.0.
1. IF OS/2 2.1 IS ALREADY INSTALLED
a.) From the OS/2 2.1 desktop, open the "OS/2 System" icon,
then the "System Setup" icon, then the "Selective
Install" icon.
b.) Click on the checkbox for CD-ROM device support.
c.) Click the "OK" box.
d.) When the screen displays a list of CD-ROM drives,
scroll down to "OTHER".
e.) Click on "OTHER" to select it.
f.) Click the "OK" box to confirm your selection of "OTHER".
g.) When the System Configuration screen is displayed
again, click the "OK" box.
h.) Follow the procedure in Section C, above for installing
the Hitachi Bus CD-ROM OS/2 Device Driver.
2. IF OS/2 2.1 IS BEING INSTALLED FROM CD-ROM DISC
When OS/2 2.1 is distributed on a CD-ROM disc, the system
is booted from 2 floppy diskettes, labelled "Installation
Diskette" and "Diskette Number 1". In order to use your
Hitachi bus drive for the CD-ROM installation it is necessary
to modify one of these diskettes to recognize the Hitachi
bus CD-ROM drive.
a.) Make a backup copy of the diskette labelled "Diskette
Number 1".
b.) Copy the Hitachi bus CD-ROM module to "Diskette Number
1". This module will be HITCDISA.ADD for ISA/EISA bus
compatible computers or HITCDMC.ADD for Micro Channel
computers.
c.) Edit the CONFIG.SYS file, which is located on the
diskette labelled, "Diskette Number 1".
d.) Add one of the following lines to the end of CONFIG.SYS
on that diskette:
BASEDEV=HITCDISA.ADD /P:300
<OR>
BASEDEV=HITCDMC.ADD
Do not include a path on the BASEDEV= line.
It is not necessary to include the /P: parameter after
HITCDMC.ADD for Micro Channel computers.
If the Hitachi bus interface card in an ISA/EISA bus
compatible computer is set for an address other than
the default of 300, modify the /P: parameter after
HITCDISA.ADD to show the address of the card. Valid
addresses are 200, 220, 240, 260, 300, 320, 340 and 360.
e.) Save this edited CONFIG.SYS file on the diskette labelled
"Diskette Number 1".
f.) Begin the installation of OS/2 2.1 as specified in your
IBM documentation.
3. IF YOU ARE USING OS/2 2.0
IBM has made various improvements and bug fixes to the generic
CD-ROM support files since OS/2 2.0 was released. It is
highly recommended that you upgrade to OS/2 2.1.
The new IBM CD-ROM Device Manager Driver, OS2CDROM.DMD, will
work with OS/2 2.0. If you upgrade to OS/2 2.1, you will
receive this module. It is also available on the IBM National
Support Center (NSC) Bulletin Board as well as on CompuServe.
The NSC Bulletin Board can be reached at (404) 835-6600, and
is further described in the OS/2 2.0 documentation.
The file date of the OS2CDROM.DMD module should be March, 1993
or later. Beta versions of the module before March, 1993 will
not work as a "DEVICE=" type device driver.
If you do not upgrade to OS/2 2.1, there may still be some
CD-ROM related issues that will not be solved with the new
OS2CDROM.DMD module. For example, if there is no CD-ROM disc
in the drive at boot time, the icon for the CD-ROM drive will
look like a floppy diskette instead of like a CD-ROM disc.
a.) From the OS/2 2.0 Desktop, open the "OS/2 System" icon,
then the "System Setup" icon, then the "Selective
Install" icon.
b.) Click the "OK" box from the System Configuration window.
c.) Click on the checkbox for CD-ROM Device Support.
d.) Click on the "More..." box on the CD-ROM Device Support
line.
e.) Click to put check marks next to both the options listed.
f.) Click the "OK" box.
g.) Click the "Install" box.
h.) Continue the installation of OS/2 2.0 CD-ROM support as
specified in your IBM documentation, inserting the
OS/2 diskettes as you are prompted.
i.) Edit the CONFIG.SYS file.
j.) Remove or comment out the following line:
DEVICE=OS2\CDROM.SYS /Q /I
k.) Add the following line:
BASEDEV=OS2CDROM.DMD
l.) Save the CONFIG.SYS file.
m.) Follow the procedure in Section C, above for installing
the Hitachi Bus CD-ROM OS/2 Device Driver.
