*** Release Notes for HIT-IDE.SYS Ver.1.06 ***

1. General

   HIT-IDE.SYS is the device driver for DOS CD-ROM Extensions that supports 
   ATAPI CD-ROM drives.

2. Command line switches of 'HIT-IDE.SYS'

   (1) SYNTAX
   
    DEVICE = [x:][\dir\]HIT-IDE.SYS /D:(device name) [/N:(number of drives)]
	     [/T:(drive type)] [/S:(base I/O address)] [/V]
	     
   (2) Meaning of switches
   
       /D:(device name)         Specifies "Device Name".
       
       /N:(number of drives)    Specifies number of drives to be supported
				by this driver.  Values 1 to 8 are valid.
				If this switch is omitted, the driver will 
				search for all connected drives.

				NOTE:  To speed the booting process, use
				/N:1 if you only have one drive connected.
				The search will stop after the first drive
				is found.
       
       /T:(drive type)          Specifies the first drive type to begin to 
				support.  
				Definition of drive types are as follows:
				
				/T:   base I/O address    master/slave
				---------------------------------------------
				0     1F0h(primary port)  master
				1     1F0h(primary port)  slave 
				2     170h(2nd port)      master
				3     170h(2nd port)      slave 
				4     1E8h(3rd port)      master
				5     1E8h(3rd port)      slave 
				6     168h(4th port)      master
				7     168h(4th port)      slave 
				
				If this switch is omitted, it is the same as
				/T:0.
				
				NOTE:  To speed the booting process, use
				/T:1 if you know your drive is connected
				to the primary slave.  Use /T:2 if your 
				drive is connected to the secondary master.
				The search will start at this number and
				continue until /N:(number of drives) are 
				found.
       
       /S:(base I/O address)    Change IRQ number to the specified base I/O
				address.
				
				base I/O           IRQ No.
				 address    without /S:    with /S:  
					     (default)    (alternate)
				----------------------------------------------
				170h            15              10
				1E8h            12              11
				168h            10              9
				(1F0h)          (14)            (14)
	
	/V                      Display installation information.

				NOTE:  Use the /V option to show you where
				your drive(s) are connected.  Then you can
				use the /T: and /N: options to speed your
				booting process in the future.

3. Examples of installation

	<Case 1> -- Default is automatic search for all drives connected.
     
		DEVICE = HIT-IDE.SYS /D:MSCD001
		
		-- Install all drives connected to primary, 2nd, 3rd & 4th.

	<Case 2> -- Using /N: switch to limit the maximum number of drives.

		DEVICE = HIT-IDE.SYS /D:MSCD001 /N:2
		
		-- Install maximum of 2 drives while auto searching,
		beginning the search with Primary Master.

	<Case 3> -- Using /T: switch to change the start of automatic search.

		DEVICE = HIT-IDE.SYS /D:MSCD001 /T:2
		
		-- Search beginning at /T:2 (2nd port and master).  Continue
		searching through /T:7.

	<Case 4> -- Using /N: and /T: switches together.

		DEVICE = HIT-IDE.SYS /D:MSCD001 /T:2 /N:2 
		
		-- Search beginning at /T:2 installing maximum 2 drives.
		
	<Case 5> -- A single drive is connected to Primary Slave.

		DEVICE = HIT-IDE.SYS /D:MSCD001 /T:1 /N:1
		
		-- Search beginning at /T:1 installing only 1 drive.
		
	<Case 6> -- A single drive is connected to Secondary Master.

		DEVICE = HIT-IDE.SYS /D:MSCD001 /T:2 /N:1
		
		-- Search beginning at /T:2 installing only 1 drive.
		
	<Case 7> -- Using /S: switch to use alternate IRQ numbers.
	
		DEVICE = HIT-IDE.SYS /D:MSCD001 /S:170,168
		
		-- Auto search all drives using alternate IRQ numbers
		   for 170 (IRQ 10) and for 168 (IRQ 9).   Use default 
		   IRQ numbers for others (1F0 IRQ 14; 1E8 IRQ 12).
		
	<Case 8> -- Using all switches together.
	
		DEVICE = HIT-IDE.SYS /D:MSCD001 /T:2 /N:1 /S:170
		
		-- Install only 1 drive starting search at 2nd port master.
		   Use alternate IRQ of 10 for 170.
		
	
4. For Windows 95

   If you are using the CDR-7730 drive on a DOS/Windows 3.x system and 
   you upgrade your system with Windows 95, Windows 95 will automatically 
   upgrade your system appropriately and the CDR-7730 will work well.
   
   If you are using Windows 95 and then adding the CDR-7730 drive, please 
   run the "CDSETUP.EXE" program from the installation disk for the CDR-7730 
   under Windows 95 and restart your system.  After this, the CDR-7730 
   will work well.
