| OVERVIEW |
------------
This README describes an OS/2 device driver (LU005s.ADD) for the
Mitsumi CD-ROM drives. The device driver supports the older
Mitsumi CRMC-LU005, and LU002 minus the CD player in MMPM/2
that I've noticed so far.
This device driver does support the older Mitsumi CRMC-LU002
CD-ROM drive (also known as the Tandy CDR-1000 or BSR-6800),
but again without CD-player from MMPM/2.
THIS CD-ROM DEVICE DRIVER IS DESIGNED TO BE USED WITH THE OS/2 2.1 PRODUCT
AND IS GOVERNED BY THE TERMS AND CONDITIONS OF THE OS/2 PROGRAM LICENSE
AGREEMENT.
----------------
| INSTALLATION |
----------------
Before starting the installation procedure, you should unzip the
files included in the MITL002.ZIP file and copy them to a diskette.
The diskette you created will be referred to as the "Mitsumi CD-ROM Device
Driver Diskette" in the following installation instructions.
The following files are included in the MITL002.ZIP file:
LU005s.ADD - OS/2 device driver for Mitsumi LU005, LU002
LU002.DDP - Mitsumi device driver installation profile
README.MIT - This README file.
Installation if OS/2 2.1 is already installed on your fixed disk
----------------------------------------------------------------
1. Run the Device Driver installation program
a. Open the OS/2 System folder on the desktop.
b. Open the System Setup folder.
c. Open Device Driver Install.
d. Insert the "Mitsumi CD-ROM Device Driver Diskette"
e. Select Install
f. Select the device driver to install from the list
g. Select OK.
(Note: You do not need to reboot OS/2 before starting step 2 below).
2. After the Device Driver Installation is complete, you must run
Selective Install to install the files for the OS/2 CD-ROM Device
Manager and OS/2 CD-ROM File System.
a. Open the OS/2 System folder on the desktop.
b. Open the System Setup folder.
c. Open Selective Install
d. Select the CD-ROM Device Support check box
e. Select OK
f. Scroll to the bottom of the CD-ROM device list table and
select the choice OTHER
g. Select OK
h. Select the OK push button to proceed from the System Configuration
screen to the OS/2 Setup and Installation window
i. Select Install
j. When prompted to do so, insert the numbered installation diskettes
or installation CD-ROM from the OS/2 2.1 product.
3. If you have changed the base I/O port address on your CD-ROM
host adapter card from the default value of 300, you must edit
your CONFIG.SYS file and add the /P:nnn parameter on the
BASEDEV=LU005s.ADD statement in your CONFIG.SYS file. Refer to
the "Mitsumi Device Driver Parameters" section below.
4. Shut down and restart your system
Installation from the CD-ROM version of OS/2 2.1
------------------------------------------------
1. Make a copy of the OS/2 2.1 diskette labeled "Diskette 1"
2. Copy the file LU005s.ADD from the "Mitsumi CD-ROM Device Driver
Diskette" to the root directory on the copy of the OS/2 2.1 Diskette 1.
(Note: If there is not enough room on the copy of OS/2 2.1
Diskette 1, then delete the file IBM2SCSI.ADD. If you delete
IBM2SCSI.ADD, you must also edit the CONFIG.SYS file and delete
the line BASEDEV=IBM2SCSI.ADD)
3. Edit the CONFIG.SYS file located on the copy of Diskette 1.
At the end of the file, add the following statement.
BASEDEV=LU005s.ADD /P:nnn
where "/P:nnn" is the base I/O port address selected on the
CD-ROM host interface card. The default base I/O port address
for the Mitsumi interface card is 300, so the statement would
appear as follows if the card is set to address 300:
BASEDEV=LU005s.ADD /P:300
4. Begin the installation by inserting the Installation Diskette
into drive A and restarting the system. When prompted to insert
Diskette 1, insert the copy that you modifed.
5. When the System Configuration screen is displayed during installation,
the CD-ROM Device Support field will display "None". Do not modify
the choice and continue with the installation.
6. After installation is complete, and you have rebooted your system,
you will not be able to access your CD-ROM drive. This is due
to a defect in the OS/2 2.1 install program. To access your
CD-ROM drive, perform the following steps:
a. Copy the following files from the OS/2 2.1 Diskette 1
to the drive which OS/2 was installed.
(Note: the example assume C:, change if different)
COPY A:OS2CDROM.DMD C:\OS2
COPY A:CDFS.IFS C:\OS2
b. Edit the CONFIG.SYS file on drive which OS/2 was installed
and add the following statements to the end of the file:
(Note: the example assume C:, change if different)
DEVICE=C:\OS2\OS2CDROM.DMD /Q
IFS=C:\OS2\CDFS.IFS /Q
c. Shut down and reboot the system
7. You will need to run Selective Install to copy over some remaining
system files.
a. Open the OS/2 System folder on the desktop.
b. Open the System Setup folder.
c. Open Selective Install
d. Select the CD-ROM Device Support check box
e. Select OK
f. Scroll to the bottom of the CD-ROM device list table and
select the choice OTHER
g. Select OK
h. Select the OK push button to proceed from the System Configuration
screen to the OS/2 Setup and Installation window
i. Select Install
j. When prompted to do so, insert the installation CD-ROM
from the OS/2 2.1 product.
Installation from the diskette version of OS/2 2.1
--------------------------------------------------
1. Install the OS/2 2.1 product from the diskettes
2. Go to the section above titled "Installation if OS/2 2.1 is already
installed on your fixed disk".
------------------------------------
| Mitsumi Device Driver Parameters (Not tested)|
------------------------------------
This section lists the parameters which are supported for the
Mitsumi CD-ROM device driver. The parameters can be changed by modifying
the BASEDEV=LU005s.ADD line in config.sys. It is recommended
to change the transfer mode from it default, software polling transfer,
to software interrupt transfer. This will help lower the CPU utilization
of CD-ROM applications, enabling better performance for other tasks
while the CD-ROM drive is being accessed. See the /I parameter below.
For the LU005s.ADD device driver, the syntax for the line in config.sys
is as follows:
BASEDEV=LU005s.ADD [/P:nnn] [I:nn] [/V]
[/P:nnn]
Specifies the base I/O port address of the interface card. This must be
the same number as specified by the DIP switch on the interface card.
[/I:nn]
Specifies the interrupt request (IRQ) channel number. This must
match the value specified on the jumper setting on the interface
card. If this parameter is not specified, the device driver will
use software polling transfer.
[/V]
The device driver will display the device driver revision level
and CD-ROM product information at boot time.
For example, if the host adapter is configured for a base I/O port
address of 0x310 and an IRQ channel of 10, the line in config.sys should
appear as follows:
BASEDEV=LU005s.ADD /P:310 /I:10
--------------------
| Trouble shooting |
--------------------
1. If you are not able to access the CD-ROM drive:
a. Make sure the Base I/O Port Address specified by the /P parameter
in the config.sys file matches the Base Port Address selected
with the DIP switch on the interface card.
The default Base I/O Port Address for the Mitsumi interface card is
address 0x0300. If you have changed the Base I/O Port Address on
the card, you must change the /P parameter on the BASEDEV=LU005s.ADD
statement in config.sys.
For example, if you changed the Base I/O Port Address to 0x0310, the
statement in config.sys should be as follows:
BASEDEV=LU005s.ADD /P:310
b. Make sure all the required files to operate the CD-ROM drive have
been installed. You should have the appropriate BASEDEV=
statement in CONFIG.SYS for your CD-ROM device driver. You
should also have the following statements for the CD-ROM system
files in your config.sys:
DEVICE=C:\OS2\OS2CDROM.DMD /Q
IFS=C:\OS2\CDFS.IFS /Q
DEVICE=C:\OS2\MDOS\VCDROM.SYS
BASEDEV=LU005s.ADD /P:300
If you do not have the above statements in your config.sys, you
must use the OS/2 2.1 Selective Install to install the CD-ROM
support files.
2. If the performance of background OS/2 tasks seems slow when the CD-ROM
drive is accessed. Or, if the performance of the MMPM/2 Software Motion
Video clips seems slow or jerky.
a. The LU005s.ADD device driver should be run using the Software
Interrupt transfer option to enable the best performance in OS/2.
The IRQ (interrupt request) channel assigned by the jumper on the
interface card must match the the interrupt channel specified using
the /I parameter on the BASEDEV=LU005s.ADD statement in config.sys.
You must assign an IRQ channel that is not being used by any other
interface cards on your computer.
For example, to enable the Software Interrupt transfer option for
IRQ channel 10 (which is the default IRQ for the card), the
statement in config.sys should be as follows:
BASEDEV=LU005s.ADD /P:300 /I:10
3. If the drive letter assigned to the CD-ROM drive under OS/2 is
different than the drive letter assigned under DOS.
The CD-ROM drive is assigned the next available drive
letter after drive letters have been assigned for the
floppy drives and fixed disk drives.
The drive letter is also assigned after any installable block
device drivers which are located in config.sys before the
DEVICE=C:\OS2\OS2CDROM.DMD statement (i.e. DEVICE=C:\OS2\VDISK.SYS).
There is currently no mechanism in OS/2 for assigning a specific
drive letter for the CD-ROM drive. The drive letter assignment
under DOS can be controlled by using the /L switch on MSCDEX.EXE
command line.
I was helped in writing this by the person who made the zip file mitfx.zip
Sorry for copying some of your material but I am not a CD-ROm expert
and anything that is said in this article should be taken with caution as I do
not and will not admit to knowing anything about CD-Rom's in general and especially for OS/2
I solely made this zipped file for the convenience of people with the Drive LU002 from
Mitsumi/ Tandy CDR-1000/BSR-6800. I apologize for any use of your name Mitsumi/
Tandy/BSR but I am not making any money off of this so don't even try to sue me cause
my net worth is about $100 at any given time. Anything that may happen to your CD-rom
disk/drive/ your hardware is solely your responsibility, as I said I just made this file for YOUR
convenience as it worked for me. Don't expect me to answer any questions but I will do
what I can to get answers for you if you'd like to mail me.!!!!

A measly freshman at UC/don't send me any money. And I will give you the
zipped up origional file in this "package" also. This gives you information
on the author(s) along with the file LU005s.add.
Excuse the typos. I do not accept responsibility for anything said in this article.
Good Luck and happy OS/2ing!
