=======================================================================
                IDE CD-ROM Support for OS/2 Warp 3.0
=======================================================================

Please Read Entire Document for Full Explanation of Procedures
--------------------------------------------------------------

DESCRIPTION

This document includes a list of compatible IDE CD-ROMs. For additional
CD-ROM information, see the following documents:

* OSCMMCDR - General CD-ROM Information for OS/2 Warp
* OSMMCDDD - OS/2 Warp CD-ROM Compatibility List

RESOLUTION

IDE CD-ROM Support
------------------
The IDE hard-disk driver, IBM1S506.ADD, recognizes ATAPI devices as 
generic. IBMIDECD.FLT, a filter, loads afterwards and scans for the 
generic ATAPI devices. When it locates an ATAPI device, it detects if 
the device is a CD-ROM. OS2CDROM.DMD and CDFS.IFS are required for the 
CD-ROM to work.

Note: The IDE CD-ROM cannot be configured as the Master. IBMINT13.I13
      cannot be used for the IDE CD-ROM.

Following are compatible IDE CD-ROMs:

* Mitsumi: FX00IDE

* NEC: CDR-250
       CDR-260
       CDR-2vi

* Sony: 55D
        55E

* Panasonic: 571

* Wearnes: CDD-120

  Note: For the Sony 55D and 55E, and the Mitsumi FX001IDE, download
        the current level of OS/2 Warp FixPak.

All IDE CD-ROMs need to comply with ATAPI 1.2 or higher. If the drivers
are not at this level, contact the vendor for updated drivers.

For NEC 260 compliant with 1.7, the BASEDEV=IBM1S506.ADD statement in 
the CONFIG.SYS files should be:

   BASEDEV=IBM1S506.ADD /A:x /U:y /ATAPI

/A refers to the number of the adapter the CD-ROM is attached to.

/U refers to the unit or device number of the particular adapter.

/ATAPI enables ATA Packet Interface protocol.

If the CD-ROM is attached to the second IDE port or adapter in a system,
and is the only device on the adapter, edit the CONFIG.SYS statement to 
read:

   BASEDEV=IBM1S506.ADD /A:1 /U:0 /ATAPI

After Installation, IDE CD-ROM is Not Installed
-----------------------------------------------
OS/2 Warp 3.0 is installed. When restarting the system, the IDE CD-ROM 
is not recognized, or support is not installed.

1. Open System Setup
2. Select Selective Install
3. Select CD-ROM support
4. Highlight Other IDE CD-ROM Support from the CD-ROM selection list.

   Note: During installation, the brand of the CD-ROM was selected;
         for example, Sony or NEC.

5. Continue the installation until complete.
6. Remove the CD and restart the system.

The statements in the CONFIG.SYS file are:

   IBM1S506.ADD /A:? /U:? /ATAPI (? is the correct parameter needed;
     see above)
   BASEDEV=IBMIDECD.FLT
   DEVICE=C:\OS2\BOOT\OS2CDROM.DMD
   IFS=C:\OS2\BOOT\CDFS.IFS

The drivers for these statements and the CD-ROM are in the OS2\BOOT 
subdirectory.
