In addition to the SCSI attached CD-ROM drives listed above,
the following manufacturers are currently developing OS/2 CD-ROM device
drivers for their non-SCSI CD-ROM drives. These device drivers
are not part of this beta package. Please contact the
manufacturer for information on availability and distribution.

Hitachi CDR-1700S, CDR-3600, CDR-3700
Availability: First Quarter 1993

Creative Labs Soundblaster Pro with CD-ROM Interface




The CD-ROM device drivers included in this beta package can be applied
to systems which have any of the following OS/2 versions installed:

* OS/2 2.0
* OS/2 2.0 with Service Pack installed.
* OS/2 2.00.1 (pre-loaded version of OS/2)


This beta package also includes updates to the OS/2 2.0 Adapter
Device Drivers (.ADDs) for the IBM, Future Domain and Adaptec
SCSI adapters. These updated drivers are required to support
the new CD-ROM device drivers.

If you have a SCSI adapter from a manufacturer other than IBM,
Future Domain or Adaptec, you must acquire an OS/2 Adapter Device
Driver (.ADD) from the manufacturer of the adapter. The generic
INT 13 driver, IBMINT13.I13, which can be used to support a fixed disk,
cannot be used to support a CD-ROM drive. The following manufacturers have
developed, or are in the process of developing, an OS/2 Adapter Device Driver
to support their SCSI adapters. You must acquire the latest Adapter Device
Driver from the manufacturer to be compatible with the CD-ROM drivers
contained in this package.

* Always Technology
* BusLogic
* DPT
* Mylex
* Trantor (.ADD files must be dated 9/15/92 or later)
* UltraStor



INSTALLATION OF ADAPTER DEVICE DRIVER (.ADD) FOR IBM, FUTURE DOMAIN
OR ADAPTEC SCSI ADAPTER
--------------------------------------------------------------------------
All installation instructions below are written for a system which is
configured for booting OS/2 from the C: partition. If your boot drive is
other than C:, please substitute your boot drive letter for C:.


1. If you already have an Adapter Device Driver for your IBM, Future Domain
or Adaptec SCSI Adapter installed when you originally installed
OS/2 2.0, please rename the .ADD file to another file name. This
will serve as a backup copy in case the installation fails and you need
to get back to your original setup.


2. Copy the new .ADD file for your SCSI Adapter from this beta package to the
C:\OS2 directory. The table below lists which adapter device driver
is required to support your SCSI adapter.

Adaptec AIC 6260 AHA152X.ADD
Adaptec AHA 1510 AHA152X.ADD
Adaptec AHA 1520/1522 AHA152X.ADD
Adaptec AHA 1540/1542 AHA154X.ADD
Adaptec AHA 1640 AHA164X.ADD
Adaptec AHA 1740/1742/1744
(Standard mode operation) AHA154X.ADD
(Enhanced mode operation) AHA174X.ADD

Future Domain TMC-850/860/875/885 FD8XX.ADD
Future Domain TMC-1660/1670/1680 FD16-700.ADD
Future Domain MCS-600/700 FD16-700.ADD
Future Domain TMC-850IBM FD850IBM.ADD
Future Domain TMC-7000EX FD7000EX.ADD

IBM SCSI Adapter IBM2SCSI.ADD
IBM SCSI Adapter with cache IBM2SCSI.ADD


3. If you do not already have a "BASEDEV= " statement in your config.sys
file for your SCSI adapter device driver, then you must add one.
For example, if you have an IBM SCSI Adapter, you need to add
the following statement to your config.sys file:

BASEDEV=IBM2SCSI.ADD (DO NOT SPECIFY A PATH)



INSTALLATION OF NEW CD-ROM DEVICE DRIVERS
-----------------------------------------
All installation instructions below are written for a system which is
configured for booting OS/2 from the C: partition. If your boot drive is
other than C:, please substitute your boot drive letter for C:.


1. If you have previously installed OS/2, you should have the following
statement in your config.sys file. If you do not, add the following
statement to your config.sys.

DEVICE=C:\OS2\MDOS\VCDROM.SYS


2. If you have previously installed CD-ROM support for OS/2, you
should have the following statement in your config.sys. If you
do not, add the following statement to your config.sys.

IFS=C:\OS2\CDFS.IFS /Q


3. Comment out the following line in your config.sys. The CDROM.SYS
driver which shipped with OS/2 2.0 is being replaced.

REM DEVICE=C:\OS2\CDROM.SYS /Q /N:4


If you are using the generic data only CD-ROM driver, CDROM_G.SYS,
which was included with the Professional Developers Kit, then comment
out the following line in your config.sys.

REM DEVICE=C:\OS2\CDROM_G.SYS /Q /N:4


4. Look for the "BUFFERS= " statement in your config.sys file.
If the value assigned to the "BUFFERS= " statement in config.sys
is 32 or greater, change the value to 31 or less, (i.e. BUFFERS=30).
There is a bug in the OS2KRNL initialization which can cause
a Trap-D or a "Cannot find COUNTRY.SYS message" at boot time
if the value is 32 or greater, and the new OS2CDROM.DMD device
driver is loaded.


5. Copy the following files from the beta package to C:\OS2.

OS2DASD.DMD
OS2ASPI.DMD
OS2CDROM.DMD
NECCDS1.FLT
HITCDS1.FLT
SONYCDS1.FLT
TOSHCDS1.FLT


6. Add the following statement to config.sys:

BASEDEV=OS2CDROM.DMD (DO NOT SPECIFY A PATH !)

WARNING: The above statement MUST be placed in the config.sys file after
the statement BASEDEV=OS2DASD.DMD or else the drive letter for the CD-ROM
drive will be allocated before the drive letters for your fixed disk
and YOU WILL NOT BE ABLE TO BOOT.


7. Optionally, also add a BASEDEV= statement for one of the CD-ROM filter
drivers (.FLT) as required to support some of the CD-ROM drives specified
in the table below. Filter drivers are required to support CD-ROM drives
which adhere to the SCSI-1 standard instead of the newer SCSI-2 standard.
The filter drivers are used to convert the SCSI-2 commands generated
by the OS2CDROM.DMD module into the vendor unique SCSI-1 commands
required by the SCSI-1 CD-ROM drive.


For example, if the attached drive is an NEC CD-ROM drive, also add
the following statement:

BASEDEV=NECCDS1.FLT (DO NOT SPECIFY A PATH !)

Known Problems
---------------

1. If the value assigned to the "BUFFERS= " statement in config.sys
is 32 or greater, change the value to 31 or less, (i.e. BUFFERS=30).
There is a bug in the OS2KRNL initialization which can cause
a Trap-D or a "Cannot find COUNTRY.SYS message" at boot time
if the value is 32 or greater, and the new OS2CDROM.DMD device
driver is loaded.

2. CD-ROM drives attached to the Adaptec AHA-1640 Microchannel
adapter may experience unreliable audio operation. The problem
is being investigated.


3. CD-ROM drives attached to any of the Trantor SCSI adapters may
experience problems with some of the audio control commands,
such as changing volume levels, or muting the audio channels.
When running the National Geographic Mammals application, two
animal sounds will be heard when an animal audio choice is selected.

Trantor is currently compatibility testing their OS/2 adapter device
drivers with these new CD-ROM drivers and will update their drivers
when testing is complete.

*** Note: If you are using one of the Trantor Adapter Device Drivers
*** you must remove the /t parameter from the BASEDEV = statement
*** in your config.sys file.
***
*** i.e. BASEDEV=T128SCSI.ADD /t *** remove the /t
***




CD-ROM Drive Letter Assignments
-------------------------------
These new CD-ROM device drivers are base device drivers which are loaded
via a BASEDEV= statement in the config.sys file. Base device drivers
are loaded prior to installable device drivers (drivers loaded via a
DEVICE= statement in config.sys). Consequently, drive letters for
base block device drivers are assigned prior to drive letters assigned to
installable block device drivers. If your configuration loads multiple
installable block device drivers, (i.e. a CD-ROM driver and a
Read/Write Optical driver) and your CD-ROM device driver was not the
first one loaded, the drive letter assigned to your CD-ROM
drive will be different with these new drivers.

Also, if your system is booted with the CD-ROM drive powered off,
a drive letter will not be assigned, and any installable block device
drivers which are loaded after the CD-ROM driver will have a drive
letter assigned which is different than if the system was booted with
the CD-ROM drive powered on. A fix for this problem is being investigated.
The workaround for configurations which experience this problem
is to always boot the system with the drive powered on.
