*** Release Notes for HIT-IDE.SYS Ver.1.06d2 ***

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 one of our IDE CD-ROM drives 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 drive will work well.
   
   If you are using Windows 95 and then adding one our IDE CD-ROM drives, 
   please run the "CDSETUP.EXE" program from the installation disk for the 
   drive under Windows 95 and restart your system.  After this, the drive 
   will work well.
   


 The above specifications are subject to change.
