Please refer to the README.TXT file for more information about using 
PRD-250.


1. Windows 95 installation notes

1.1 PC Card driver

   The CD-ROM device driver for Windows 95 "SPARROW.MPD" is a 32-bit device
   driver. To use this driver, your PC card slot must use 32-bit support.
   
   To enable 32-bit support, double-click on the PC Card(PCMCIA) icon in 
   the control panel and follow the instructions of the PC Card Wizard. If
   you do not see the PC Card Wizard when you double-click the icon, your 
   PC card slot already uses 32-bit support.
   The PC Card Wizard will ask you if you are using a PC card to install 
   Windows (default answer is No.) If you used the PRD-250 when upgrading 
   Windows, you might answer Yes, but you do not need to. When upgrading
   Windows, the SCSI controller in the PC card is detected, and the 32-bit
   driver (SPARROW.MPD) is automatically loaded.

1.2 CD-ROM device driver
  
   The CD-ROM device driver is placed in the following directory after 
   installation.

	<Windows directory>\system\iosubsys

   If the driver cannot be found in the directory, you may copy it from 
   the supplied floppy disk manually by using Explorer.

1.3 Windows utility software

   When installation is done under Windows 95, the utilities bundled in 
   the supplied floppy disk (Photo CD viewer etc.) will not be installed.
   If you have installed the utilities under Windows 3.1 and upgraded 
   Windows, you can still use the utilities under Windows 95. If not, you
   may install the utilities by running "SETUP.EXE" in the supplied floppy
   disk. 
   
   Note
   Installation will give you a warning message "!!! NO SCSI ADAPTERS 
   DETECTED !!!", but click Continue and complete installation.
   
   After installation, you must restore the WINASPI.DLL file. Refer to 
   the following section (1.4 WINASPI.DLL) for details.
   
1.4 WINASPI.DLL

   If you have run "SETUP.EXE" in the supplied floppy disk, which is the 
   installation program for Windows 3.1, under Windows 95, WINASPI.DLL 
   file has been replaced with an old version and Windows 95 will give you
   a warning message. 
   In this case, you must restore the original WINASPI.DLL file. To do so,
   copy the original WINASPI.DLL file placed in the directory ASPIW95 on 
   the supplied floppy disk to the following directory:

	<Windows directory>\system 

   The warning message may appear a few more times even after you have 
   restored the file.

1.5 Installing onto a Compaq Contura Aero

   If you are installing the Windows 95 driver onto a Compaq Contura Aero,
   follow the instructions below:

	1) Connect the floppy disk drive and insert the supplied floppy 
	   disk.
	2) Copy the following files in the supplied floppy disk to the 
	   directory specified below:
	   
	   SPARROW.MPD --> C:\<Windows directory>\system\iosubsys
	   SPARROW.INF --> C:\<Windows directory>\inf

	3) Remove the PC card of the floppy disk drive and insert the 
	   PRD-250 PC card (make sure the power of the drive is ON).

	   Windows 95 detects the card and installs the necessary driver.
	   

2. Windows 3.1/DOS installation notes

2.1 CONFIG.SYS file

2.1.1 Multi-configuration

   Installation makes modifications to your CONFIG.SYS file if you did not
   choose to modify the files by yourself.

   In default, the following lines are added to the bottom of the file.

	[common]
	DEVICE=C:\SONYSC\ASPI2DOS.SYS /D /PCMCIA /Z /Qx
	DEVICE=C:\SONYSC\ASPICD.SYS /D:ASPICD0

   If you do not edit the file, the PRD-250 drivers are always loaded 
   regardless of the menu option you choose when you boot your PC.
   To avoid loading the drivers when you do not use the PRD-250, refer to 
   your DOS manual and edit the file as appropriate. 

   Following is a sample CONFIG.SYS file:

	[MENU]
	Menuitem=PRD250_MODE, PRD-250 
	Menuitem=NOCDROM_MODE, No CD-ROM
	Menudefault=PRD250_MODE, 10
	
	[COMMON]
	DEVICE=c:\DOS\HIMEM.SYS
	DOS=HIGH,UMB
	DEVICE=c:\DOS\EMM386.EXE RAM X=D000-DBFF
	LASTDRIVE=Z
	FILES=30
	STACKS=9,256
		
	[PCCARD]
	DEVICEHIGH=c:\CARDSOFT\SSVADEM.EXE /SKT:2
	DEVICEHIGH=c:\CARDSOFT\CS.EXE /IRQ F
	DEVICEHIGH=c:\CARDSOFT\CSALLOC.EXE
	Rem DEVICEHIGH=c:\CARDSOFT\ATADRV.EXE
	Rem DEVICEHIGH=c:\CARDSOFT\MTDDRV.EXE
	Rem DEVICEHIGH=c:\CARDSOFT\MTSRAM.EXE
	DEVICEHIGH=c:\CARDSOFT\CARDID.EXE
	
	[PRD250]
	DEVICE=C:\SONYSC\ASPI2DOS.SYS /D /PCMCIA /Z /Q9
	DEVICE=C:\SONYSC\ASPICD.SYS /D:ASPICD0
	
	[PRD250_MODE]
	include PCCARD
	include PRD250
	
	[NOCDROM_MODE]
	include PCCARD

   Make sure the CD-ROM drivers are loaded after the Card and Socket 
   Services have been loaded.
	
2.1.2 Loading the driver in high memory

   The PRD-250 driver can be loaded in the high memory area. To do so, 
   change "DEVICE=" to "DEVICEHIGH=" as follows:

	DEVICEHIGH=C:\SONYSC\ASPI2DOS.SYS /D /PCMCIA /Z /Qx
	DEVICEHIGH=C:\SONYSC\ASPICD.SYS /D:ASPICD0

   It will free up more conventional memory.

2.1.3 Device driver command line options
   
   You do not need to add or change any command line options. If, for 
   some reason, you need to change it, refer to the following descriptions.

   * ASPI2DOS.SYS 

   /D
   This option, which is entered automatically by installation, displays
   information about the host adapter and attached SCSI devices when
   you boot your computer.

   /PCMCIA
   This option indicates that the host adapter is APA-1460 PCMCIA SCSI
   Card.

   /Z
   The /z option sets all default options. Do not remove this option from
   the command line.

   /Qx
   This option does not mean anything when the host adapter is APA-1460.

   /PAUSE
   This option makes your system pause after loading ASPI2DOS.SYS at boot
   time so you can read the message on the screen. After you read it, press
   any key to resume the booting process.

   *ASPICD.SYS
   
   /D:<name>
   This option, which is required in the CONFIG.SYS command line, assigns
   a name to the CD-ROM drive so that MSCDEX(Microsoft MS-DOS CD-ROM
   Extensions) can install the CD-ROM as a logical drive letter. 

   /PAUSE
   This option makes your system pause after loading ASPI2DOS.SYS at boot
   time so you can read the message on the screen. After you read it, press
   any key to resume the booting process.


2.2 AUTOEXEC.BAT file

   Installation adds following line to the AUTOEXEC.BAT file.

	C:\SONYSC\MSCDEX.EXE /D:ASPICD0 /M:12 /L:E

   The command line option /D:ASPICD0 corresponds to the device name 
   specified in the ASPICD.SYS command line option /D:ASPICD0.

   If you use another CD-ROM device, add the device name to the above
   MSCDEX.EXE line.
   Following is an example:

	C:\SONYSC\MSCDEX.EXE /D:ASPICD0 /D:MSCD001 /M:12 /L:E

   If the drive letter "D:" is assigned to ASPICD0, "E:" will be assigned
   to the device MSCD001.

2.3 Installing onto a Compaq Contura Aero

   If you are installing the Windows 3.1/DOS driver onto a Compaq Contura
   Aero, follow the instructions below:

	1) Connect the floppy disk drive and insert the supplied floppy 
	   disk.
	
	2) Create a temporary directory in the C: drive (ex. C:\sony).

		C:\>md sony <Enter>

	3) Copy all the files contained in the floppy disk to the temporary
	   directory.

		C:\>copy a:*.* sony <Enter>
	
	4) Remove the PC card of the floppy disk drive and insert the 
	   PRD-250 PC card (make sure the power of the drive is ON).

	5) Run "c:\sony\setup" from Windows command line or run "dosinst"
	   from the c:\sony directory. 
	   
	6) Follow the instructions on the screen to complete installation.

	7) Remove the temporary directory.

		C:\>deltree sony <Enter>

2.4 IRQ

   The ASPI manager ASPI2DOS.SYS searches for an available IRQ number 
   between 9 to 12 when it is loaded in the booting process. You cannot 
   specify the IRQ number to be used.

 
3. Troubleshooting

3.1 For Windows 95 users

a) The "New Hardware Found" window does not appear when you insert the 
   PC card.

     ->	The PC card slot of your PC is not using 32-bit support.
	Refer to the instructions manual and install the 32-bit PC card 
	driver. 

     ->	Your CONFIG.SYS file contains PC card driver lines. They may 
	conflict with the 32-bit driver. Remove the PC card related
	lines from your CONFIG.SYS file. 

     -> The PC card has already been configured.
	If you do not see a CD-ROM drive icon in My Computer window, delete
	the device (refer to the troubleshooting section of the Users 
	Manual) and install it again. 

b) Windows 95 does not detect the PRD-250.

     -> The power of the drive has been turned off when it is connected to
	your PC.
	Remove the PC card (make sure you stop the PC card by clicking the
	PC card icon in the Task Bar) and insert it again. 


If you still cannot operate the PRD-250 under Windows 95, do the following.

	1) Insert the PRD-250 PC card.
	2) Open Control Panel -> System -> Device Manager and double-click
	   SCSI Controllers.
	3) Click Adaptec APA-1460 SCSI Host Adapter and click Remove.
	4) Remove the PC card.
	5) Insert the supplied floppy disk and copy the following files to 
	   the directory specified below:
	   
	   SPARROW.MPD --> C:\<Windows directory>\system\iosubsys
	   SPARROW.INF --> C:\<Windows directory>\inf

	6) Turn on the drive and insert the PC card again. 


3.2 For Windows 3.1 / DOS users

a) A message "Host adapter at port address xxx failed diagnostics" appears
   when booting your PC.

     -> The port address is conflicting with another device.
	The PRD-250 uses I/O address either 340h-35Fh or 140h-14Fh. If both
	are used by other devices, free up one of the above addresses.

     -> The PC card is not seated firmly in the slot. 
	Remove the card and insert the PC card again firmly.

     -> The ASPI2DOS.SYS line is placed before the Card and Socket Services
	lines.
	Move the ASPI2DOS.SYS line and the ASPICD.SYS line after the Card
	and Socket Services lines.

b) A message "CD-ROM driver NOT LOADED: no valid Adaptec host adapter"
   appears when booting your PC.

     -> Power is not supplied to the PRD-250. 
	Press the Play button to turn on the power and reboot your PC 
	again.

c) You cannot move to the CD-ROM drive letter.
   You do not see a CD-ROM icon in the Windows File Manager.

     -> You have multiple MSCDEX lines in your AUTOEXEC.BAT file.
	Refer to section 2.2 of this file and combine them into one.


If you still cannot operate the PRD-250 under Windows 3.1 / DOS, check 
the following points:

	1) Card and Socket Services Release 2.1 or higher is installed.
	   (If you are not sure, consult your PC manufacturer.)
	2) The following lines are present after Card and Socket Services
	   lines in the CONFIG.SYS file.

		DEVICE=C:\SONYSC\ASPI2DOS.SYS /D /PCMCIA /Z /Qx
		DEVICE=C:\SONYSC\ASPICD.SYS /D:ASPICD0
	
	3) The following line is present in the AUTOEXEC.BAT file.

		C:\SONYSC\MSCDEX.EXE /D:ASPICD0 /M:12 /L:E

	4) You turned on the drive and inserted the PC card before booting
	   your PC.
