2. Copy the file SONY535.ADD from the "Sony 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=SONY535.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 Sony CDB-242 interface card is 340h, so the statement
would appear as follows if the card is set to address 340h:
BASEDEV=SONY535.ADD /P:340

---------------------------------
| Sony Device Driver Parameters |
---------------------------------
This section lists the parameters which are supported for the
Sony CD-ROM device driver. The parameters can be changed by modifying
the BASEDEV=SONY535.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 SONY535.ADD device driver, the syntax for the line in config.sys
is as follows:
BASEDEV=SONY535.ADD [/P:nnn] [/I:nn] [/U:d,d...] [/V]
[/P:nnn]
Specifies the base I/O port address of the interface card.
The value must be the same number as the port address selected
by the jumper on the host 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.
Note: Some Sony host adapter cards did not ship with the plastic
jumper switch to select the IRQ channel on the IRQ jumper block.
You must obtain and install the plastic jumper switch to enable
the IRQ channel.
[/U:d,d...]
Specifies the drive unit number which the Sony CD-ROM drive is
set to. The value of d must be set to 0,1,2 or 3. If more than
one Sony CD-ROM drive is attached to the adapter, this parameter
must be specified. If only one CD-ROM drive is attached to the
adapter, and this parameter is not specified, then the default unit
id used by the driver is 0.
[/V]
The device driver will display the device driver revision level
and CD-ROM product information at boot time.
Sony CDU-535 Device Driver Parameter Examples
---------------------------------------------
1. Sony CD-ROM drive attached to Sony CDB-240 series host adapter:
For example, if the Sony host adapter is set to a base I/O port
address of 360, the line in config.sys should be:
BASEDEV=SONY535.ADD /P:360
2. Sony CD-ROM drive attached to Sony CDB-240 series host adapter.
If the Sony CD-ROM drive is attached to the Sony host adapter at
base I/O port address of 360h, and the driver is operating in interrupt
mode at IRQ channel 5, the line in your config.sys should be:
BASEDEV=SONY535.ADD /P:360 /I:5
3. Multiple Sony CD-ROM drives daisy chained to Sony CDB-240 series
host adapter
For example, if two Sony CD-ROM drives are daisy chained from
the Sony host adapter with the first drive set to drive unit 0
and the second set to drive unit 1, the line in config.sys
should appear as follows:
BASEDEV=SONY535.ADD /P:340 /U:0,1
--------------------
| Known Problems |
--------------------
1. Slow transfer rate on some 386 class machines.
We are investigating a problem with slow transfer rates on some
386 class machines. The transfer rate on those machines only
achieves a transfer rate of 75K/sec, instead of the 150KB/sec which
the drive supports.
--------------------
| Trouble shooting |
--------------------
1. If you are not able to access the CD-ROM drive:
a. Add the /V parameter switch to the BASEDEV=SONY535.ADD statement
in your CONFIG.SYS file. For example:
BASEDEV=SONY535.ADD /P:340 /V
After rebooting, the device driver will display the list of
drives it has identified. For example:
IBM OS/2 SONY535.ADD 1.00
SONY CDROM CDU-535-01 1.0a Port:340 Units: 0 IRQ:Polled
If no units were detected, the following message is displayed:
IBM OS/2 SONY535.ADD 1.00
No units detected.
If no units were detected, see step 1b below.
If units were detected, see step 1c below.
b. 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 Sony interface card
is address 340h. If you have changed the Base I/O Port Address on
the card, you must change the /P parameter on the BASEDEV=SONY535.ADD
statement in config.sys.
For example, if you changed the Base I/O Port Address to 360h, the
statement in config.sys should be as follows:
BASEDEV=SONY535.ADD /P:360
c. 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=SONY535.ADD /P:340
If you do not have the above statements in your config.sys, you
must use the OS/2 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 SONY535.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=SONY535.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 5, the statement in config.sys should be as follows:
BASEDEV=SONY535.ADD /P:340 /I:5
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.
----------------------
| Reporting Problems |
----------------------
Bug reports must include the following information:
CD-ROM Product ID: i.e. Sony CDU-535-01
CD-ROM Firmware Level: i.e. 1.0a
Device Driver Transfer Mode: Software Polling or Interrupt driven
Machine Model: i.e. Dell 466/M
Host CPU type and speed: i.e. 25MZ 486
The CD-ROM product ID and firmware level can be displayed at
boot time by adding the /V switch to the BASEDEV=SONY535.ADD line
in config.sys. For example, the following line may be displayed at boot
time after the OS/2 logo screen is displayed:
SONY CDROM CDU-535-01 1.0a Port:340 Units: 0 IRQ:Polled
The firmware level in the above example is 1.0a.
