OSDIN260 - NEC 260 IDE CD-ROM NOT RECOGNIZED BY OS/2 WARP
01/16/96
=======================================================================
NEC 260 IDE CD-ROM Not Recognized by OS/2 Warp
=======================================================================
Please Read Entire Document for Full Explanation of Procedures
--------------------------------------------------------------
DESCRIPTION
A NEC 260 IDE CD-ROM is not being recognized by OS/2 Warp.
RESOLUTION
Note: Make sure you have a backup of any file you intend to change.
Make sure the proper drivers are loading in the CONFIG.SYS file, and
that the necessary files are in the correct directories.
If you have installed OS/2 Warp and are trying to get the CD-ROM
recognized:
1. Go to OS/2 Selective Install.
2. Select CD-ROM Device Support.
3. Select NEC 260 from the list of CD-ROMs and select OK.
4. Select OK again.
5. Select Install. You need the OS/2 Warp Installation diskettes to
continue.
6. Insert the diskettes when prompted to complete installation.
7. Upon completion, go to an OS/2 command prompt; then type
E CONFIG.SYS to edit the CONFIG.SYS file in the root directory.
8. Change: BASEDEV=IBM1S506.ADD
To: BASEDEV=IBM1S506.ADD /A:x /U:y /ATAPI
(/A refers to the adapter number that the CD-ROM is attached to;
/U refers to the unit or device number on a particular adapter;
/ATAPI enables ATA Packet Interface protocol for the NEC 260.)
If the CD-ROM is attached to the second IDE port or adapter in a
system, and is the only device on the adapter, you would have:
BASEDEV=IBM1S506.ADD /A:1 /U:0 /ATAPI
The CONFIG.SYS file also should have the statements:
BASEDEV=IBMIDECD.FLT
DEVICE=C:\OS2\BOOT\OS2CDROM.DMD
IFS=C:\OS2\BOOT\CDFS.IFS
These were added by Selective Install.
If you are trying to install OS/2 Warp from the NEC 260 CD-ROM, edit
the CONFIG.SYS file on Diskette 1 and set the BASEDEV=IBM1S506.ADD
statement as above. If OS/2 still does not recognize the CD-ROM, make
sure that the /A and /U parameters are specified correctly. Contact NEC
if you still have a problem.
