Comments on "Device Driver & Utilities Ver. 1.8m"
=================================================
1) Applicable model list:
* The utilities on this diskette apply to the following models.
1. CDU50E
2. CDU55D
3. CDU55E
4. CDU75E
5. CDU76E
6. CDU77E
7. CDU17E
2) Improvements:
* ver. 2.24a-->2.25a (ver. 2.25a is not released officially.)
Media Player with Windows 3.1 cannot play Enhanced CD (CD Plus) correctly.
The problem occurs when Media Player tries to play its data track as
a normal audio track.
To correct this, the command format for Enhanced CD has been changed
as outlined below. Thanks to these changes, data track is not recognized by
Media Player and the problem is resolved.
(Although audio tracks can be played correctly, other features
implemented in the Enhanced CD are not usable by Media Player.)
[IOCTL]
<Return Volume Size>
Lead-out start address of 1st session +150
<Audio Disk Info>
-Highest Track number
final track number of 1st session
-Starting point of the lead-out track
Lead-out start address (MSF) of 1st session
<Audio Track Info>
Return the track information of 1st session only
The above changes are cancelled with option "/h".
* ver. 2.25a-->2.26a
When a track with an index no. above 10 is played on Audio Application
Program, the wrong index no. is indicated. This is because the format of the
index given in Audio Q-channel of IOCTL Input is binary, not BCD.
The format of the index has been changed from binary to BCD to correct this.
3) Device Driver information
* To find out which device driver version you are using, there
are two methods:
1. Use either debugger or dump software to see ASCII information in
the device driver where you will be able to find the version level.
2. Note the version level when the device driver is loaded during boot stage of
MS-DOS system.
* However, the above methods may not be easy for some users so the
following information has been added to help our customers identify the
version level of each device driver for our ATAPI CD-ROM drive.
With the information given below, the version level can be identified
based on the file size and the time stamp information.
ATAPI_CD.SYS 22016 94-07-22 16:04 <<=== 2.00a
ATAPI_CD.SYS 22016 94-07-22 16:04 <<=== 2.14a
ATAPI_CD.SYS 24144 94-10-28 20:14 <<=== 2.16a
ATAPI_CD.SYS 26048 94-11-10 12:14 <<=== 2.17d
ATAPI_CD.SYS 26128 94-12-05 19:07 <<=== 2.18b
ATAPI_CD.SYS 26848 95-01-08 20:26 <<=== 2.19c
ATAPI_CD.SYS 26864 95-02-14 11:03 <<=== 2.20a
ATAPI_CD.SYS 28976 95-04-12 13:45 <<=== 2.22a
ATAPI_CD.SYS 29616 95-07-14 09:39 <<=== 2.24a
ATAPI_CD.SYS 30272 95-09-28 16:14 <<=== 2.26a
4) Comments:
* This floppy disk contains the installation software "SETUP.EXE" Version 2.99d.
* This device driver (ver. is 2.26a) supports "Enhanced CD". However,
this is cancelled with option "/h".
* MSCDEX is not included because of a licensing agreement with Microsoft.
MSCDEX.EXE is included in DOS 6.x, but it is also possible to
download it from Microsoft BBS.

6) Installation for Windows 95
Case 1) Windows 95 standard installation
There should be no problem installing the CD-ROM drive under Windows 95. The
following instructions will guide you through the installation process. For
details on each installation step, please refer to the relevant note.
After Hardware installation (make sure Master or Slave setting is correct)
-Run Windows 95. (see note a)
- if the CD-ROM device is recognized by Windows ->End
- if the CD-ROM device is not recognized by Windows ->see next instruction
-Click under My Computer; Control Panel; Add New Hardware icon. (see note b)
- if the CD-ROM device is recognized by Windows ->End
- if the CD-ROM device is not recognized by Windows ->see next instruction
-Start the SETUP.EXE program from this diskette. (see note c)
- if the CD-ROM device is recognized by Windows ->End
- if the CD-ROM device is not recognized by Windows ->see next instruction
-Get in contact with your dealer to get further instructions.
note a) Just start Windows 95 and it should automatically recognize the
new Sony CD-ROM drive and load Windows 32-Bit device driver.
note b) Click on the Start, Settings,Control Panel, and Add New Hardware icon.
The Add New Hardware Wizard window will appear. Click on the Next button
continuously. Windows 95 will detect the new configuration. Re boot the
computer, run Windows 95 and verify the 4X CD-ROM drive setting by clicking
on the My Computer icon. The CD-ROM drive icon will appear.
note c) Insert the disk labeled "MS-DOS Device Driver & Utilities for Sony ATA-PI
CD-ROM Drive" into the floppy drive. Click on the Start button on the pop
up menu and select the Run option. When the dialog box appears, type
A:\SETUP and click on the OK button. The installation menu will appear.
Follow the instructions of the SETUP utility. Re boot the computer, run
Windows 95, and verify the 4X CD-ROM drive setting by clicking on the My
Computer icon. The CD-ROM drive icon will appear.
Case 2) Using CD-ROM drive under MS-DOS by restarting computer in MS-DOS
mode.
If you want to use CD-ROM drive under MS-DOS by restarting computer in
MS-DOS mode, you should follow this installation procedure.
Insert the disk labeled "MS-DOS Device Driver & Utilities for Sony ATA-PI
CD-ROM Drive" into the floppy drive.
Execute SETUP.EXE, then the installation menu will appear. Follow the
instructions of the SETUP utility.
After that, use your DOS editor to edit the AUTOEXEC.BAT file by typing
C:\edit AUTOEXEC.BAT and insert REM at the beginning of the following
line as shown:
REM C:\WINDOWS\COMMAND\MSCDEX.EXE /D:mscd000 /M:12 /V
Save this modification by selecting File, Save, and Exit from the editor.
Then use your DOS editor to edit the DOSSTART.BAT file by typing C:\edit
C:\WINDOWS\DOSSTART.BAT and add the following line:
C:\WINDOWS\COMMAND\MSCDEX.EXE /D:mscd000 /M:12 /V
Save this modification by selecting File, Save, and Exit from the editor.
Now restart your computer run Windows 95, and choose restart computer in
MS-DOS mode. The CD-ROM drive is now available in MS-DOS mode.
Case 3) Using CD-ROM drive under MS-DOS by previous MS-DOS mode or command
prompt mode only.
If you want to use CD-ROM drive under MS-DOS by Previous MS-DOS mode or
Command Prompt only mode, you should follow this installation procedure.
Insert the disk labeled "MS-DOS Device Driver & Utilities for Sony ATA-PI
CD-ROM Drive" into the floppy drive. Execute SETUP.EXE, then the installation
menu will appear. Follow the instructions of the SETUP utility.
After restarting Previous MS-DOS mode or Command Prompt only mode, the CD-ROM
drive will now be available in these modes.
7) Option for the device driver, ATAPI_CD.SYS
a) /D:<device_name>
* Device driver needs to have a <device_name> listed on the command
line MSCDEX following the /D: switch. MSCDEX uses this
parameter to locate device driver. Names used must match those
used for the /D:<device_name> parameters for each device entry
in "AUTOEXEC.BAT".
* The installation software specifies the device name as "mscd000",
which appears in "CONFIG.SYS" as well as "AUTOEXEC.BAT".
b) /I:n
* This option is related to "Media Change Command" and "Illegal
disc change", specified in MSCDEX. It is required
to notify the system that a disc has been changed so that this
information can be used in various ways, eg. to initialise
a buffer memory with directory information, etc.
However, there are several ways of treating this
information so we have added an option "/i:n" to allow the
user to choose an appropriate setting.
* No option at all.
If the drive tries to access a CD-ROM when there is no disc in the drive,
it will return "illegal media change". This in turn will be expressed as
"Not ready error reading.." and displayed on the screen.
This will not be cleared straight away, even after a CD-ROM disc is
inserted, but second retry will clear this message.
* n=0
Our installation software will set this option, because we feel
this is more appropriate than default setting which is specified by
MSCDEX specification.
Note : Some major SCSI products vendors have this setting as
their default setting.
* n=1
The driver will keep returning "Media Change Status" until
"Media Change Command (A command which checks if the media
has been changed or not) is executed. During this stage, the system
will keep displaying the following message on the screen, even
after media has been loaded.
Not ready error reading drive X:
Abort, Retry, Ignore?
(* X: Drive letter of CD-ROM drive)
* /i .... Same as "/i:1"
c) /p:XXX
When user specifies one of the following address, ie. /p:xxx,
the device driver selects the only specified port address.
Primary /p:1F0
Secondary /p:170
Tertiary /p:1E8
Quaternary /p:168
F.D. board /p:160 (Futuredomain)
However, the F.D. board's address(160H) and Quaternary's
address(168H) can not be used together.
Without specifying this option, the device driver can select the
drive by "auto-detect" mode in any of the Primary, Secondary,
Tertiary, Quaternary, and F.D. board.
d) /g
When connecting a Sony drive as master through the ATA interface with a
Green PC, and if no other slave device is connected, the device driver responds with
"Drive not Ready" to any command from the host computer after the host computer
enters suspend mode.
Option "/g" is added to solve this problem.
e) /h
This option cancels Enhanced CD support.
8) Option for MSCDEX.EXE
a) /D:<device_name>
* Device driver needs to have a <device_name> listed on the command
line to MSCDEX following the /D: switch. MSCDEX uses this parameter
to locate the device driver. Names used must match those used for the
/D:<device_name> parameters for each device entry in "CONFIG.SYS".
* The installation software specifies the device name as "mscd000",
which appear in "CONFIG.SYS" as well as "AUTOEXEC.BAT".
b) /M:<value>
This option switch determines how many sector buffers MSCDEX
allocates when it installs itself. The larger the value, the
more sector cache entries are available and the less MSCDEX will
have to read directly from the CD-ROM drive. Please increase this value
if you require better performance, but bear in mind that it will use up
system memory space. It is also possible to reduce the value, but a
minimum of 4-5 is recommended. If this value is too small, the drive
will reread more often which will deteriorates its performance.
c) /V
This is "verbose switch". /V asks MSCDEX to print additional
information about memory usage during initialisation. We recommend
setting this switch.
d) Others
There are a few other switches which are not set using "SETUP.EXE".
The following explanations are given for users who need to
customise the CD-ROM system.
* /E
This is an additional switch which tells MSCDEX to use expanded
memory if it is available.
* /L:<drive letter>
This option is for software that requires a specific
drive letter so that the application software can interface with CD-ROM drive
without problems.
Because "SETUP.EXE" does not set this switch, you will have to
edit your AUTOEXEC.BAT file if this switch is needed.
For example, to assign CD-ROM drives starting at
the letter L:, you would need to add the switch "L", as you can see below:
MSCDEX /D:MSCD001 /L:L
* /K
The /K switch causes MSCDEX to look for a Supplementary Volume
Descriptor that identifies a shift-JIS Kanji volume for Japanese.
* /S
The /S switch tells MSCDEX to patch MS-DOS to allow sharing of
CD-ROM drives on MS-NET based servers.
