******** Information for custom setting the driver *********
****** for the Double Speed SONY CDU31A/CDU33A series ******

To install device driver in config.sys:

	device=slcd.sys  /B:xxx  /d:mscd000  /v   /c  /m:x  /t:x  /k  /n

	/B:	Base port address of host adapter.  340H is the default.

	/d:	Specifies device driver name.  Used by MSCDEX.  This is the 
		current value if none is specified in config.sys.
	/v	Turns on verbose mode of the driver.  Driver displays 
		information about its installation.
	/c	Turns on displaying of drive configuration at boot time.

	/m:	Data transfer mode:  p = polled I/O, d = DMA, which requires 
		the /t:x parameter.

	/t:	Specifies the DMA channel to use if DMA transfer mode is 
		selected.

	/k	Enables a sector caching mechanism to improve the performance.
		The default is off.	
	/n	/2 specifies the double speed mode.  /1 specifies the single 
		speed mode.  The default is the double speed mode.


	lastdrive=z

	Last valid drive letter.  DOS defaults to 'e'.  If you have 3 or more
	hard disks, or ram disks, this must be used to expand the number of 
	letters available.

To install Microsoft CD-ROM Extensions via autoexec.bat:

	mscdex  /d:mscd000  /l:m

	/d:	Name of CD-ROM device driver.  Must match the value specified 
		in config.sys.  This is the name recommended by Microsoft.

	/l:	Specifies the drive letter to use for the CD-ROM. If this, 
		'/l:m' is not here, the next available drive letter is used.

NOTES for CDPLAY Ver.2.1 

1. If the program starts under DOS/V J mode, it automatically switches the
   screen mode to English from DOS/V J mode, and restores it before exiting.
2. Control file (CDPLAY.CTL) is not necessarily required.  
   When the file does not exist, the program automatically scans the valid 
   CD-ROM drive.
3. The program can be terminated by Esc key at any time.

******************************************************************************

NOTES for older version of MSCDEX.

   There are old version of MSCDEX provided under each sub directory
which sub directory name represents each version level.  The reason in
providing these old version is to be used where user faces combination
problem which may be solved using an old version of MSCDEX, though we are
sure that the latest version of MSCDEX serves its purpose under any
environment.
