Q1:  How can I use my CD-ROM with WindowsNT and/ or OS/2 ?

A1:      Microsoft WindowsNT version3.5 and IBM OS/2 version3.0 
        "Warp"include device drivers for New Sony Bus,SCSI and ATA-PI
        CD-ROM Drives.    

Q2:  How and when do I terminate my CD-ROM drive?

A2:     The answer to this question depends upon the type of CD-ROM you
        are using.If you are using an ATA-PI(40PIN) or New Sony Bus
        (34PIN) CD-ROM,termination is not required. If you are using an 
        old Sony Bus (40PIN)or SCSI(50PIN)CD-ROM drive,termination is 
        required at both ends of the chain. Normally,the interface card
        and last drive are terminated. However,if you are using a 
        combination of internal and external devices and they are all 
        attached to the same interface card,termination is required 
        on the last internal and last external device,but must be 
        removed from the interface card.   

Q3:  Who supports the sound card and it's software and drivers? 

A3:     If the sound card was included in the same box as a Sony CD-ROM 
        and the outside of the box says"Sony DeskTop Library", then 
        Sony supports the sound card. For all other cases,the sound card 
        is supported by the company whose name appears on the outside of
        the box.

Q4:  Which lines must be in my AUTOEXEC.BAT and CONFIG.SYS files in order
     for my computer to communicate with my CD-ROM?

A4:     There are two devices drivers required to operate a CD-ROM drive 
        on the DOS based computer. One is activated by a line in CONFIG
        .SYS and one is activated by a line in AUTOEXEC.BAT. The identity
        of the driver referenced in AUTOEXEC.BAT is independent upon the 
        operating system being used. Here are four examples that should 
        illustrate this point:

Q6:  What are the Option for the device driver, ATAPI_CD.SYS?

A6:
   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 "SONY_4X0",
        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"
