About PCDS.SYS Driver

 The PCDS.SYS driver is a dual purpose driver for use in AT-
 type and XT-type PCs. The driver is Multimedia Personal 
 Computer (MPC) compliant in computers meeting the MPC 
 specifications. The PCDS.SYS driver directly controls the 
 CD-ROM drive via the Controller Card. It provides an 
 interface between the hardware and MSCDEX. MSCDEX translates 
 High Sierra and ISO 9660 CD-ROM discs into a format that DOS 
 can understand. MSCDEX talks directly to PCDS.SYS. 

 With the driver installed, the CD-ROM drive gets a DOS drive 
 identification letter, which to DOS looks just like any other 
 disk drive except that it will appear to be removable and 
 write protected. It may also look to DOS like a remote drive 
 when used by some applications.


About Multimedia Personal Computer Compatibility

 Multimedia Personal Computer (MPC) is a standard for the 
 combination of sound, graphics animation and video on 
 personal computers. Installation of a CD-ROM drive alone 
 will not bring your computer up to the MPC standard. Other 
 items needed to become fully MPC compatible include the 
 following: an 80386sx processor or better, an MPC-compliant 
 sound board, a VGA video adapter, a color VGA monitor, at 
 least 2MB of extended memory, an extended memory manager, a 
 3.5" floppy drive (1.44MB capacity), a 30MB hard drive, a 
 101 key keyboard, a two button mouse, a Serial Port, a 
 Parallel Port, a MIDI I/O Port and a Joystick Port.

 For MPC compatibility, you should have an extended memory 
 manager installed before running the CD-ROM drive 
 installation. HIMEM.SYS, which comes with your DOS 5.0 (or 
 greater) package, is an example of an extended memory 
 manager. Please refer to your DOS manual for installation 
 instructions of HIMEM.SYS.	   


Attention Windows NT Users

 If you are using the Windows NT operating system, first 
 follow the directions in the "PCDS-DS CD-ROM Driver 
 Installation" section in this readme file, then go to 
 the "Windows NT CD-ROM Driver Installation" section and 
 complete the instructions as they are presented.

 NOTE: The Windows NT operating system requires the PCDS-DS's
 Controller Card to be set to IRQ 5.


PCDS-DS CD-ROM Driver Installation

 The software installation disk included with the PCDS-DS 
 includes an automatic installation program that installs 
 the required driver onto your fixed disk drive and modifies 
 the CONFIG.SYS and AUTOEXEC.BAT files. To run the automated 
 installation, follow the directions below.

 1. Turn your computer on, and wait for it to boot. You 
    should boot from your normal boot drive.

 2. Insert the CD-ROM driver disk into Drive A, and type:

      A:Install 	

    This command installs the drivers on the drive that you 
    specified in the startup window. 
	
    If you are using the Controller Card's default jumper 
    settings, choose the Basic Installation. If you have 
    changed the Controller Card's base I/O address or wish 
    to customize the installation, choose Custom Installation.
   
   
    NOTE: If you have changed the Controller Card's base I/O 
    address from its default setting, you must choose the Custom 
    Installation option and, when prompted, select the option 
    which reflects the Controller Card's base I/O address jumper 
    setting.

    The existing CONFIG.SYS and AUTOEXEC.BAT files will be 
    backed up as CONFIG.OLD and AUTOEXEC.OLD, and then the 
    installation program will install the drivers into the 
    current CONFIG.SYS and AUTOEXEC.BAT files. 

 3. When the installation is finished, press [CTRL]+[ALT]+ 
    [DEL] to re-boot the computer.


Windows NT CD-ROM Driver Installation

 Before beginning this section you must have:

   o Windows NT CD-ROM and Windows NT "Setup Disk For CD-ROM 
     Installation" diskette.

   o Completed the instructions in the "PCDS-DS CD-ROM Driver 
     Installation" section.

   o A blank diskette.


 NOTE: The Windows NT operating system requires the PCDS-DS's
 Controller Card to be set to IRQ 5.

 To begin the Windows NT CD-ROM Driver Installation, follow 
 these steps:

 1. Insert a blank, formatted diskette into your floppy 
    drive.

 2. Copy all files from the Windows NT directory, 
    "\DRVLIB\STORAGE\SONY-31A\X86" on the Windows NT CD-ROM to 
    the diskette in your floppy drive.

 3. Once the files are copied to the diskette, eject it.

 4. Insert the "Setup Disk For CD-ROM Installation" boot-
    diskette and reboot your computer.

 5. At the "Welcome to Setup" window, press .

 6. Select "Custom Setup" by pressing C.

 7. To add the miniport device driver for the PCDS-DS (Sony 
    CDU31A) select "S" in the "Windows NT Setup" window. The 
    next window will present a driver selection box. Select 
    "Other..." and then insert the diskette that you created in 
    step 2.

 8. Follow the directions as they are presented.


PCDS Command Line Options

 This section covers the PCDS.SYS command line options. The 
 default command line options should be adequate for your 
 use. However, if you would like to change some of the 
 software's functions, continue to read this section. This 
 section is included for the more advanced user. New users 
 should not attempt to change the following options without 
 first obtaining a working knowledge of the software and its 
 interaction with the CD-ROM drive.

 The following describes the syntax of the command line 
 options:

   LASTDRIVE = n
   DEVICE = C:\PCDS\PCDS.SYS /B:xxx /D:name

 The LASTDRIVE = n line defines the highest letter that MS-DOS 
 will recognize as a locally attached disk drive. The n value 
 can be any letter from C to Z. Most network computers, if 
 installed, will assign drive letters to remote volumes 
 starting after the drive letter defined as LASTDRIVE.
 Example:

   If you have a computer with two floppy disk drives 
   (drives A and B), a hard disk drive (drive C) with multiple 
   partitions (drives D, E, and F) and a CD-ROM drive (drive 
   G), LASTDRIVE = G would be appropriate. 


PCDS.SYS Driver Switches

 The /V switch turns on the verbose mode of the driver. With 
 this switch on, the driver displays information about its 
 installation.

 The /C switch turns on displaying of drive configuration at 
 boot time.

 The /B:xxx switch specifies the base I/O address of the 
 Controller Card in hexadecimal. The available selections for 
 base I/O address are 320H, 330H, 340H and 360H. If the 
 /B:xxx switch is not specified, the driver defaults to 340H. 
 If the Controller Card is set to a base I/O address other 
 than 340H, the /B:xxx switch must be used with xxx 
 specifying the address selected on the Controller Card. For 
 example, if the base I/O address setting of the Controller 
 Card were set to 320H, then the /B:xxx switch must be 
 /B:320.

 The /D:name switch is optional. If you need to change the 
 device driver name, you must specify the new name here. 
 Changing the name is rarely necessary. For example, if you 
 have another type of CD-ROM driver loaded along with your 
 PCDS.SYS driver, the driver will need a unique name for 
 MSCDEX to distinguish them. The default device driver name 
 is MSCD001.

 The /K switch enables a sector caching mechanism to improve 
 the performance. The default setting for this switch is off.

 CONFIG.SYS Example 1

   LASTDRIVE = H
   DEVICEHIGH = C:\PCDS\PCDS.SYS /B:320 /D:MSCD001

 In the above example, appearing in your CONFIG.SYS file, the 
 drive letter H will be the highest drive letter that MS-DOS 
 will recognize as a locally attached disk drive. The PCDS.SYS 
 driver, which is located in the C:\PCDS subdirectory, will be 
 loaded with the base I/O address set at 320 and the device 
 driver name of MSCD001. 

MSCDEX.EXE Command Line Options

 The loading instructions installed in the AUTOEXEC.BAT file by the 
 automatic installation program look like this:

   MSCDEX /D:MSCD001

 The /D : MSCD001 switch in the above example is providing 
 the name of the CD driver to the MSCDEX.EXE driver. This 
 information must be supplied to the MSCDEX.EXE driver; 
 otherwise, you won't be able to access any CD-ROMs. This 
 name must match the name specified by the /D: switch of the 
 PCDS.SYS line in your CONFIG.SYS file.

 If your AUTOEXEC.BAT file starts up a "shell" program such 
 as Windows, or if it runs another BAT file, make sure that 
 the line, which starts MSCDEX.EXE, is ahead of the line that 
 starts your "shell" or BAT file. If the line that starts 
 MSCDEX.EXE is not ahead of the line that starts the 
 "shell" or BAT file, MSCDEX.EXE has no chance to start the 
 CD-ROM drive once your "shell" or BAT file begins.

 After installing the drivers, press [CTRL]+[ALT[+[DEL] to 
 re-start your computer and load the drivers.


Other MSCDEX.EXE Switches

 Other switches are recognized by the MSCDEX.EXE driver. 
 These switches can be used to modify the behavior of the 
 MSCDEX.EXE driver, and must be added to the MSCDEX.EXE 
 line in the AUTOEXEC.BAT file. You can use the CD-ROM 
 drive without the options, but they can be used in certain 
 situations as described below.

 The /S switch indicates to the MSCDEX.EXE driver to patch  
 MS-DOS so that it will work with MS-NET based servers. With 
 this switch on, load MSCDEX after the network redirector, 
 but before the network server software. This allows the CD-
 ROM drives to be shared by the MS-NET based server.

 The /M : n switch determines how many buffers the MSCDEX.EXE 
 driver is to allocate for a directory cache when it is installed. 
 The larger this value is, the more directory cache entries become 
 available. Typically, the greater the value, the better your CD-ROM 
 drive performance will be. By experimenting with the n value, you 
 can determine the optimum value for your computer. Each buffer 
 uses 2K of memory. The default value is 4 buffers, or 8K of memory.

 The MSCDEX.EXE driver requires small amounts of additional 
 memory to run efficiently. This requirement should cause no 
 problems. If, after you have installed the MSCDEX.EXE 
 driver, you find some programs cannot be completely run 
 because there is not enough memory, you should review your 
 CONFIG.SYS and AUTOEXEC.BAT files to locate other entries 
 that consume memory you may not require and can therefore 
 remove. Typically, such drivers might be GRAPHICS or 
 FASTOPEN. The larger the value specified in the /M: switch, 
 the more memory will be consumed.

 The /V switch tells MSCDEX.EXE to display additional 
 information about memory usage during initialization.

 The /L : letter switch specifies the DOS drive letter to be 
 used for CD-ROMs. If your particular application requires 
 the CD-ROM drive to be assigned a specific drive letter, use 
 this switch; otherwise, the CD-ROM drive will be given the 
 next available drive letter.

 The /E switch tells MSCDEX.EXE to use expanded memory, if 
 such memory is installed and available. This requires using 
 an Expanded Memory Manager driver such as those included 
 with some computers or with add-in memory boards (i.e., EMM 
 386 with DOS 5.0).

 The /K switch indicates to the MSCDEX.EXE driver to scan for 
 the SVD (Supplementary Volume Descriptor) instead of the PVD 
 (Primary Volume Descriptor). When you specify the /K switch, 
 MSCDEX uses the SVD that identifies a JIS Kanji volume for 
 Japanese if it is present, otherwise, it uses the PVD.


EJECTCD, LOCKCD, And UNLOCKCD Utilities

 This section describes the four additional utilities 
 shipped with the PCDS-DS software installation diskette. 
 These utilities are copied to the C:\PCDS subdirectory by 
 default during installation. The installation also adds a 
 path to this subdirectory so that the utilities can be 
 executed from any DOS prompt. 


EJECTCD Utility

 The EJECTCD utility is used to eject the CD from the PCDS-DS. 
 The LOCKCD utility is used to disable the PCDS-DS's Eject 
 Button. The UNLOCKCD utility will re-enable the PCDS-DS's Eject
 Button. To use any of these utilities, simply go to the DOS prompt 
 and type:

  EJECTCD

    or 

  UNLOCKCD

    or 

  LOCKCD


PLAYCD.EXE Utility

 This utility lets you play ordinary audio CDs with your PCDS-DS. 
 The automatic installation program copies PLAYCD.EXE to a 
 directory called \PCDS by default.

 To hear the music, you must connect either headphones or 
 amplified speakers to the PCDS-DS's front headphone jack. You 
 can also use the PXCDS-DSs rear RCA jacks to connect a stereo 
 amplifier. To use the program, go to the DOS prompt and type:

   PLAYCD      <<Enter>>

 Note: If you get an error message like:

 Device Driver Not Installed as: MSCD001 or MVCD001. No Valid 
 Driver Was Found.

 then type:

   PLAYCD /d:name  <<Enter>>

 where name is the name specified by the /D: switch in the 
 PCDS.SYS line in the CONFIG.SYS file.

 The PLAYCD.EXE utility menu has a numbered box at the top of 
 the screen that shows the track numbers on your audio CD. 
 Use the up-down-left-right arrow keys on your keyboard to 
 highlight the desired button, then press  to execute the 
 button's function. Press  if you need help or additional 
 explanation of the selected function. Explanations and 
 instructions appear on your screen and are described briefly
 in the following paragraphs.
