//============================================================================


I.	Hardware Requirement for AZTECH IDE CD-ROM Drive

	For OS/2 2.1x system, you need to have another IDE interface card for IDE CD-ROM
	drive. You should not connect an IDE CD-ROM drive to the primary IDE controller card
	which is connected to your IDE hard disk.

	There are four IDE ports:

		Primary IDE port:		1F0 (hex)
		Secondary IDE port:		170 (hex)
		3rd IDE port:			1E8 (hex)
		4th IDE port:			166 (hex)				

	IRQ for IDE CD-ROM:
		
		IRQ 14 (normally this is used by IDE hard disks)
		IRQ 15
		IRQ 10
		IRQ 11
	
	IDE hard disks normally use the primary IDE port and IRQ 14. Since IRQ is not sharable
	in OS/2 2.1 in ISA bus, you should use the secondary IDE port and IRQ 15 for IDE CD-ROM
	drive if they are available, and so on. 
					

II.	Using AZTECH IDE CD-ROM Drive to Install OS/2 2.1
-----------------------------------------------------


	1.	Make a copy of OS/2 Diskette 1.
	
	2.	Copy the AZT268I.ADD file from the AZTECH IDE CD-ROM Device Driver Diskette to 
		the root directory on the copy of OS/2 Diskette 1.
	
	3.	Edit the CONFIG.SYS file located on the copy of OS/2 Diskette 1. At the end of
		the file, add the the following line:
		
			BASEDEV=AZT268I.ADD /P:nnn /I:nn /V
			
		where	/P:nnn	-- nnn is the CD-ROM IDE I/O port address in Hex.
				/I:nn	-- nn is IRQ number in decimal
				/V		-- Verbose
				
		Do not specify a file path for the AZT268I.ADD file.
		
	4.	Begin the installation by inserting the Installation Diskette into drive A: and
		restarting the system. When prompted to insert Diskette 1, insert the copy
		that you modified.
		
	5.  When the System Configuration screen is displayed during installation,
	    the CD-ROM Device Support field will display "None".  Do not modify
	    the choice and continue with the installation.

	6.  After installation is complete, and you have rebooted your system,
	    you will not be able to access your CD-ROM drive.  This is due
	    to a defect in the OS/2 2.1 install program.  To access your
	    CD-ROM drive, perform the following steps:

	    a. Copy the following files from the OS/2 2.1 Diskette 1
	       to the drive which OS/2 was installed.
	       (Note: the example assume C:, change if different)

	       COPY A:OS2CDROM.DMD C:\OS2
	       COPY A:CDFS.IFS     C:\OS2

	    b. Edit the CONFIG.SYS file on drive which OS/2 was installed
	       and add the following statements to the end of the file:
	       (Note: the example assume C:, change if different)

	       DEVICE=C:\OS2\OS2CDROM.DMD /Q
	       IFS=C:\OS2\CDFS.IFS /Q

	    c. Shut down and reboot the system

	
	7.  You will need to run Selective Install to copy over some remaining
	    system files.

	    a. Open the OS/2 System folder on the desktop.
	    b. Open the System Setup folder.
	    c. Open Selective Install
	    d. Select the CD-ROM Device Support check box
	    e. Select OK
	    f. Scroll to the bottom of the CD-ROM device list table and
	       select the choice OTHER
	    g. Select OK
	    h. Select the OK push button to proceed from the System Configuration
	       screen to the OS/2 Setup and Installation window
	    i. Select Install
	    j. When prompted to do so, insert the installation CD-ROM
	       from the OS/2 2.1 product.

		
III.	Install AZTECH IDE CD-ROM Drive to an Existing OS/2 2.1 System
--------------------------------------------------------------

	1.	Run DDINSTAL program from OS/2 System.

	   a. Open the OS/2 System folder on the desktop.
	   b. Open the System Setup folder.
	   c. Open Device Driver Install.
	   d. Insert the "AZTECH CD-ROM Device Driver Diskette"
	   e. Select Install
	   f. Select the device driver to install from the list
	   g. Select OK.

	
	2. After the Device Driver Installation is complete, you must run
	   Selective Install to install the files for the OS/2 CD-ROM Device
	   Manager and OS/2 CD-ROM File System.

	   a. Open the OS/2 System folder on the desktop.
	   b. Open the System Setup folder.
	   c. Open Selective Install
	   d. Select the CD-ROM Device Support check box
	   e. Select OK
	   f. Scroll to the bottom of the CD-ROM device list table and
	      select the choice OTHER
	   g. Select OK
	   h. Select the OK push button to proceed from the System Configuration
	      screen to the OS/2 Setup and Installation window
	   i. Select Install
	   j. When prompted to do so, insert the numbered installation diskettes
	      or installation CD-ROM from the OS/2 2.1 product.


	3. If you have changed the base I/O port address on your CD-ROM
	   host adapter card from the default value of 634, you must edit
	   your CONFIG.SYS file and add the /P:nnn parameter on the
	   BASEDEV=AZT268I.ADD statement in your CONFIG.SYS file.


	4. Shut down and restart your system
