A. IBM OS2 IDE CDROM Installation:

   1. This zip file includes the following files from the IBM BBS
      (407-443-9000):

	IBM1S506.ADD	11-10-1994
	IBMIDECD.FLT	11-10-1994
	OS2CDROM.DMD	11-10-1994

      If IBM provides newer CDROM drivers with new feature or bug fixed
      in the BBS, please download and use the updated drivers.

      A DTC OS2 driver - DTCIDE.ADD is also included in the zip file.

   2. Backup IBM OS2 "Diskette 1". Copy these files to this backup
      diskette. If the diskette has not sufficient space, delete
      FD8XX.ADD, FD16-700.ADD, FD7000X.ADD and DPT20XX.ADD. For any
      file deleted, the corresponding line in the "CONFIG.SYS" file
      must also be remarked. For example,

	REM BASEDEV=FD8XX.ADD

   3. Edit the configuration file "CONFIG.SYS" in the backup diskette.

      Locate the BASEDEV=IBM1S506.ADD line
   
      change this line to "BASEDEV=DTCIDE.ADD /V"

      Add the lines

		DEVICE=OS2CDROM.DMD /Q
		IFS=CDFS.IFS /Q
		BASEDEV=IBMIDECD.FLT /V

      after DTCIDE line.

      Delete the repeat line in other places if there is any. For example,
      there may be a line like "DEVICE=OS2CDROM.DMD". Delete it. Note that
      no "/Q" option is specified in that line.

   4. Insert the IBM OS2 "Installation diskette" into the floppy drive and
      start the installation using the backup "diskette 1" whenever
      "Diskette 1" is requested. Choose the "Advanced Installation" rather
      than the "Easy Installation" when these options are presented.

   5. When you are asked to reboot to continue installation, insert the
      DOS bootable diskette and reboot to DOS.

   6. During the above installation, the system copied the three files

	DTCIDE.ADD
	OS2CDROM.DMD
	IBMIDECD.FLT

      to the hard disk, some from the CDROM and some from the floppy.
      Those from the CDROMs are outdated and need to be replaced by those
      from the BBS. To find DTCIDE.ADD in all directories of the hard
      disk drive, issue the command:

	DIR /S DTCIDE.ADD

      This file has the "ReadOnly" attribute set and requires
      removing the protection first before replaced. For example, to
      replace the one in the "\" directory, execute:

	ATTRIB -S -H -R C:\DTCIDE.ADD

      and place the backup "DISKETTE 1" into the floppy drive and type:

	COPY A:DTCIDE.ADD C:\DTCIDE.ADD /Y

      Update above three files in all directories similarly. Note that 
      OS2CDROM.DMD and IBMIDECD.FLT are not write protected.

   7. Reboot the system with the hard disk and continue the installation
      through completion.

   8. The CDROM is supported automatically.

B. If you encounter a problem with the DTC driver in the above procedure,
   try the IBM driver as follows:

   1. Edit the configuration file "CONFIG.SYS" in the backup diskette.

      Locate the BASEDEV=DTCIDE.ADD line and change this line to

      "BASEDEV=IBM1S506.ADD /A:0 /U:1 /ATAPI" assuming the CDROM is in Slave

      (U=1) of the primary controller (A=0),


      Add the lines

		DEVICE=OS2CDROM.DMD /Q
		IFS=CDFS.IFS /Q
		BASEDEV=IBMIDECD.FLT

      after IBM1S506 line.

      Delete the repeat line in other places if there is any. For example,
      there may be a line like "DEVICE=OS2CDROM.DMD". Delete it. Note that
      no "/Q" option is specified in that line.

   2. Insert the IBM OS2 "Installation diskette" into the floppy drive and
      start the installation using the backup "diskette 1" whenever
      "Diskette 1" is requested. Choose the "Advanced Installation" rather
      than the "Easy Installation" when these options are presented.

   3. When you are asked to reboot to continue installation, insert the
      DOS bootable diskette and reboot to DOS.

   4. During the above installation, the system copied the three files

	IBMIS506.ADD
	OS2CDROM.DMD
	IBMIDECD.FLT

      to the hard disk, some from the CDROM and some from the floppy.
      Those from the CDROMs are outdated and need to be replaced by those
      from the BBS. To find IBM1S506.ADD in all directories of the hard
      disk drive, issue the command:

	DIR /S IBM1S506.ADD

      Under OS2 WARP, it will be in the root ("\") and the "\OS2\BOOT"
      directories. This file has the "ReadOnly" attribute set and requires
      removing the protection first before replaced. For example, to
      replace the one in the "\OS2\BOOT" directory, execute:

	ATTRIB -S -H -R C:\OS2\BOOT\IBM1S506.ADD

      and place the backup "DISKETTE 1" into the floppy drive and type:

	COPY A:IBM1S506.ADD C:\OS2\BOOT\IBM1S506.ADD /Y

      Update above three files in all directories similarly. Note that 
      OS2CDROM.DMD and IBMIDECD.FLT are not write protected.

   5. Reboot the system with the hard disk and continue the installation
      through completion.

C. If both above procedures fails to install OS2 from the IDE CDROM, check
   the hardware setup including the cable orientation, drive's master/slave
   jumper setting and the connector etc. It is also possible that the CDROM
   is not supported by the "IBMIDECD.FLT" filter provided by IBM. Check with
   the CDROM vendor whether they supply their own filter code. If they do,
   replace the IBMIDECD.FLT with ther vendor's filter in the above procedures.
   
   Sometimes, the CDROM drive takes long period of time to come ready, it may
   require "warm boot" or "reset" to detect the CDROM's presence.
