================================================= 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. * Please make sure that MSCDEX.EXE exists under "C:\DOS", then execute "SETUP.EXE". * This floppy disk contains the following files 1) Device Driver : ATAPI_CD.SYS 2.26a 2) SETUP.EXE : SETUP.EXE 2.99d 3) Utility : EJECT.COM 4) Ditto : LOCK.COM 5) Ditto : UNLOCK.COM 6) Ditto : CDPLAY.EXE 7) Ditto : LOAD.EXE 8) Ditto : README.TXT (English) 9) Ditto : READMEG.TXT (German) 10) Ditto : READMEF.TXT (French) 5) Installation for Windows 3.1X After installation using "SETUP.EXE", the following lines have been added to "Config.sys" and "Autoexec.bat": < CONFIG.SYS > Device=C:\DEV\ATAPI_CD.SYS /D:mscd000 /i:0 < AUTOEXEC.BAT > C:\DOS\MSCDEX.EXE /D:mscd000 /V /M:12 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. * Note: MSCDEX is a product of Microsoft Corporation Personal Storage Products Dept.
