- Comments on "Device Driver & Utilities Ver. 1.9
- ===============================================
-
-
- 1) Applicable model list:
-
- * The utilities in this diskette are applicable to the following models.
-
- 1. CDU50E
- 2. CDU55D
- 3. CDU55E
- 4. CDU75E
- 5. CDU76E
- 6. CDU77E
- 7. CDU17E
- 8. CDU111
- 9. CDU311
-
- 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 the version level of the device driver you are using, there
- are mainly two ways, which are....
-
- 1. Use either debugger or dump software to see an ASCII information in
- the device driver where you will be able to find the version level.
-
- 2. Or, watch when the device drive is loaded during boot stage of
- MS-DOS system.
-
- * However, above method may not be easy for some users, therefore the
- following information is 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
- ATAPI_CD.SYS 30272 96-03-22 16:10 <<=== 2.27a

- 4) Comments:
-
- * This floppy disk contains an installation software "INSTALL.EXE"
- version 1.00a.
-
- * This device driver (ver. is 2.26a) supports "Enhanced CD". However,
- this is canceled with option "/h".
-
- * MSCDEX is not included because of licensing agreement with Microsoft.
- MSCDEX.EXE is included in DOS 6.x, but also it is possible to
- download from Microsoft BBS.
-
- * Please make sure that MSCDEX.EXE exists under "C:\DOS", then execute
- "INSTALL.EXE".
-
- * This floppy disk contains the following files
-
- 1) Device Driver : ATAPI_CD.SYS 2.27a
- 2) Install.Exe : INSTALL.EXE 1.00a
- 3) Utility : EJECT.COM
- 4) Ditto : LOCK.COM
- 5) Ditto : UNLOCK.COM
- 6) Ditto : CDPLAY.EXE
- 7) Ditto : LOAD.EXE
- 8) Ditto : README.TXT
-
-
- 5) Installation
-
- After installation using "INSTALL.EXE", the following lines are
- added in "Config.sys" and "Autoexec.bat", which are....
-
- < CONFIG.SYS >
-
- Device=C:\DEV\ATAPI_CD.SYS /D:mscd000 /i:0
-
- < AUTOEXEC.BAT >
-
- C:\DOS\MSCDEX.EXE /D:mscd000 /V /M:12
-
-
- 6) 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 to 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 specify the device name as "mscd000",
- which appear in "CONFIG.SYS" as well as "AUTOEXEC.BAT".
-
- b) /I:n
-
- * This option is related "Media Change Command" and "Illegal
- disc change" specified in MSCDEX specification. This is required
- to notify the system that disc has been changed so that this
- information can be used in various ways. For example, initialize
- a buffer memory with directory information, etc.
-
- On the other hand, there are several ways in treating this
- information. Therefore, we added an option "/i:n" so that
- user can choose an appropriate setting.
-
- * No option at all.
- Without this option, the drive returns "illegal media change",
- if the drive tries to access CD-ROM without disc in the drive,
- which will be, in turn, expressed as "Not ready error reading.."
- and displayed on the screen.
-
- This will not be cleared once, 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 natural 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 is to check if the media
- is changed or not) is executed. During this stage, the system
- will keep displaying the following message on the screen, even
- after a media is 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, like a /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 use 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
- In the case of connecting only Sony drive to the ATA interface of the
- Green PC as the master, the device driver returns "Drive not Ready"
- for 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 is canceled support of Enhanced CD with this option.
-
-
- 7) 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 device driver. Names used must match those used for the
- /D:<device_name> parameters for each device entry in "CONFIG.SYS".
-
- * The installation software specify 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 this value is, the
- more sector cache entries are available and the less MSCDEX will
- have to read directly from the CD-ROM drive. So, please increase
- if you require better performance, but it will take system memory
- space. It is also possible to reduce the value, but the minimum
- of 4-5 is recommended. If this value is too small, the drive will
- reread more often which will deteriorates drive's performance.
-
- c) /V
- This is "verbose switch". /V asks MSCDEX to print additional
- information about memory usage during initialization. We recommend
- to set this switch.
-
- d) Others
- There are few other switches which are not set using "INSTALL.EXE".
- The following explanations are given for users who need to
- customize 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 prepared for some software that require a specific
- drive letter for the CD-ROM drive so that the application
- software can treat CD-ROM drive without any problem.
- Because "INSTALL.EXE" does not set this switch, you will have to
- edit your AUTOEXEC.BAT file if this switch is needed.
- For example, the following assigns CD-ROM drives starting at
- drive letter L:, you need to add switch "L" as you can see as
- follow.
-
- 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.
-
-
- * Note: MSCDEX is a product of Microsoft Corporation
