Comments on "Device Driver & Utilities Ver. 2.1"
=================================================
1) Applicable models:
* The utilities and device driver on this diskette are applicable
to SONY ATAPI CD-ROM drives.
Note:
As for CD-R drives and DVD-ROM drives, these utilities and device
driver can cover only CD-ROM function. The write function of CD-R
drive and the playback function of DVD titles will require another
utility or driver.
2) Improvements:
All SONY ATAPI CD-ROM Drives do not operate correctly with a
CD-ROM Performance Test Program (CDT.EXE). SONY device driver
2.26a returns the error against IOCTL input command (Audio Disc
Info) which is issued at the start of this test program CDT.EXE.
Device driver 2.27a is changed not to return the error against
the first IOCTL input command (Audio Disc Info) after media
is changed.
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.

After that type
INSTALL
and press the ENTER button. The installation will then proceed
automatically .
Reboot the 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
ATAPI CD-ROM Drive" into the floppy drive. Type
A:
and press the ENTER key.
After that type
INSTALL /D&A
and press the ENTER key. The Installation will then proceed
automatically .
After restarting Previous MS-DOS mode or Command Prompt only mode,
the CD-ROM drive will now be available in these modes.
8) 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.
9) 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
"INSTALL.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 "INSTALL.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.
