        INSTRUCTIONS FOR SANYO CDR-H94A DEVICE SUPPORT INSTALLATION


These instructions describe the procedure required to add support for your
Sanyo CDR-H94A CD-ROM drive to a machine which already has OS/2 installed on
it.  For instructions regarding the installation of OS/2 itself from the
drive, see the section titled "INSTRUCTIONS FOR OS/2 INSTALLATION."


NOTE: If you already have OS/2 CD-ROM support installed on your machine for
another model of drive, you may proceed directly to Step 5.

1.      Open OS/2 SYSTEM.

2.      Open SYSTEM SETUP.

3.      Open SELECTIVE INSTALL.

4.      Select CD-ROM Device Support, and choose "Other" for the model of
        CD-ROM device.  Follow the prompts of the Selective Install program
        and use the Help feature if necessary.

5.      From the SYSTEM SETUP folder, open DEVICE DRIVER INSTALL.

6.      Fill in the drive letters and path information for your OS/2 system
        and the location of this device driver install package.  Note that
        this package may be run from a diskette or from a subdirectory on
        your hard disk.  Click on the Install button.

7.      Double click on the selection which ends in "Default Configuration."
        Follow the prompts of the Device Driver Install program, and use the
        Help feature if necessary.

8.      Sanyo CDR-H94A OS/2 Device Support Installation is complete.
        Shutdown your system using the desktop ShutDown utility, reboot your
        system, and your CD-ROM drive will be present and functional.

                    INSTRUCTIONS FOR OS/2 INSTALLATION


These instructions describe the procedure required to install the OS/2
operating system from the CD version on your Sanyo CDR-H94A.  For
instructions regarding the installation Sanyo CDR-H94A device support on a
machine which already has OS/2 installed on it, see the section titled
"INSTRUCTIONS FOR SANYO CDR-H94A DEVICE SUPPORT INSTALLATION."


The CD version of OS/2 comes with two floppy diskettes which are used to
boot the target machine.  After booting, the install proceeds from the
CD-ROM drive to the hard disk.  The second diskette, titled Diskette #1,
contains a config.sys file which attempts to install all OS/2 CD-ROM device
drivers.  At this time, your Sanyo driver is not included on the diskettes
which IBM ships.  You must make a backup copy of diskette 1 and modify it
before you can install OS/2 from your Sanyo CDR-H94A.  The procedure to do
this is as follows:

1.      Boot from either your existing DOS operating system, or from the
        OS/2 diskettes (selecting the command prompt option when prompted).

2.      Make a copy of diskette #1 by entering the following command:

                DISKCOPY A: A:

3.      Copy the file named SANYO001.ADD from this diskette to your newly
        created Diskette #1:

                COPY A:SANYO001.ADD A:

4.      Edit the config.sys file contained on the new diskette #1.  If you
        are unsure of how to do this, see the editor instructions in the
        section of this file titled "ADVANCED CONFIGURATION."

5.      Add the following line to the config.sys file after all the other
        BASEDEV=XXXXXXXX.ADD statements:

                BASEDEV=SANYO001.ADD

6.      Reboot from the OS/2 Installation diskette and the installation of
        OS/2 from your Sanyo-CDR-H94A will proceed as per normal.

A more detailed description of this procedure can be found in the hardcopy
version of your OS/2 Installation Guide.


----------------------------------------------------------------------------

                          ADVANCED CONFIGURATION


Advanced Configuration is accomplished by editing your config.sys file to
pass command line parameters to the Sanyo CDR-H94A device driver.  Most of
these parameters are entirely optional, although some users may be required
to make an advanced configuration.  The filename of the driver is
SANYO001.ADD, and the line in config.sys which loads this driver reads,
"BASEDEV=SANYO001.ADD."  Parameters are added to the end of this line, and
any number of them may be present.

The following parameters are recognized by the driver:

        /V      -This option causes the driver to use verbose mode, where a
                detailed message is output to the display during system
                boot.  This option is turned on by default during the
                installation of the driver.

        /Q      -This option causes the driver to use quiet mode, where no
                indication is given when the driver cannot find a CD-ROM
                drive.  This option is valuable in mobile situations where a
                drive is only present in a desktop docking station.

        /T      -This option causes the driver to enable trace mode, where
                trace information is output to the OS/2 System Trace
                Facility.  This option is only used to debug driver and/or
                operating system problems.  Since the amount of trace
                information is voluminous, enabling this option can slow the
                driver down.  This option is best left disabled.

        /P:xxx  -This option forces the driver to believe that the Panasonic
                CD-ROM interface base IO port is at the specified address.
                This option is necessary if your CD-ROM interface board is
                not configured at one of the usual base addresses.  By
                default, the driver will scan addresses 300h, 320h, 330h,
                340h, and 360h.  This option is necessary if, during
                installation, you are forced to choose the "Advanced
                Configuration" option.

The following is an example line which enables the driver in verbose mode at
address 450h:

        BASEDEV=SANYO001.ADD /V /P:450

These changes can be made with any ASCII text file editor.  If you do not
already have an editor with which you are familiar, you may use the OS/2
System Editor.  Use the following procedure:

        1.     Select OS/2 SYSTEM.

        2.     Open PRODUCTIVITY.

        3.     Open OS/2 SYSTEM EDITOR.

        4.     Select File, Open, enter c:\config.sys

        5.     Scroll to the line where SANYO001.ADD is installed and
               modify it appropriately.

        6.     IMPORTANT! - Save the file (File, Save).

                              COMMON PROBLEMS


"Drive not found" message

        If this message appears during system boot, then either the driver
        cannot find the Panasonic CD-ROM Interface, or your Sanyo CD-ROM
        drive is not physically connected properly to that interface.
        First, attempt to verify that the physical connection is correct,
        perhaps by verifying operation under another operating system such
        as DOS.

        If you are certain that the drive is connected properly, the next
        thing to do is to verify that the I/O port base address for the
        Panasonic CD-ROM interface is communicated to the driver.  Note that
        the driver will automatically scan for the interface at I/O
        addresses 300h, 320h, 330h, 340h, and 360h.  Consult the
        documentation that came with your CD-ROM interface to determine its
        base address.  See the section of this readme titled "ADVANCED
        CONFIGURATION" and pass that address to the driver and you will be
        up and running.

        If the driver still cannot find the interface, then there is one
        more option, albeit unpleasant.  If the driver had originally
        functioned OK, but couldn't find the drive the next time you turned
        the power on, that is a sure sign that your CD-ROM interface falls
        into this category.  Some CD-ROM interfaces are packaged on sound
        boards where the Panasonic interface is not enabled at power up.
        These installations are distinguished by DOS config.sys files which
        first load a DOS device driver to enable the interface, and then
        load the actual Sanyo CD-ROM driver.  You may boot from a DOS
        floppy that executes this first device driver, then do a warm boot
        via Ctl-Alt-Del to start OS/2 from the hard disk.  The OS/2 driver
        will continue to see the interface until you power down.  If your
        machine falls into this category, contact the maker of your CD-ROM
        interface board to have support for it added to this OS/2 driver.
