Configuring the NEC 260 IDE CD-ROM under OS2 Warp
Last updated: 27 Dec 1994
DESCRIPTION OF SYMPTOMS
A NEC 260 IDE CD-ROM is not being recognized by OS2 Warp.
SUMMARY OF RESOLUTION
Make sure the proper drivers are loading in config.sys and that the necessary files are located in the proper directories.
DETAILS OF RESOLUTION
If you have already installed OS2 Warp, and are trying to get the CD-ROM recognized, follow these instructions:
- Go to the OS2 Selective Install utility. From the list of CD-ROMs, select the NEC 260. Click OK. At the System Configuration window, click OK again. At the Setup and Installation window, select the Install button.
- Insert the OS2 diskette when prompted.
- Edit the OS2 config.sys in the root directory of the hard drive. Find the line:
BASEDEV=IBM1S506.ADD
Add switches to this line so that it reads:
BASEDEV=IBM1S506.ADD /A:x /U:y /ATAPI
The /A switch refers to the adapter number that the CD-ROM is attached to. The /U option references the unit or device number on a particular adapter. The /ATAPI parameter 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 enter
BASEDEV=IBM1S506.ADD /A:1 /U:0 /ATAPI
in the config.sys. If the CD-ROM is configured as a slave, or sec device, you would specify /U:1. The config.sys should also contain the statements:
BASEDEV=IBMIDECD.FLT DEVICE=C:\OS2\BOOT\OS2CDROM.DMD IFS=C:\OS2\BOOT\CDFS.IFS
These should have been added by the Selective Install program.
If you are trying to install Warp from the NEC 260 CD-ROM, simply configure the
BASEDEV=IBM1S506.ADD
line per above. If you find that OS2 still does not recognize the CD-ROM, make sure that the /A and /U parameters are specified
