You cannot access the CD-ROM or the CD-ROM icon does not display (OS/2).
Your CD-ROM device driver might not be loaded or cannot be found. Before
checking the CONFIG.SYS file, make a backup copy of this file in a convenient
directory.
1. At the DOS prompt:
a. Type copy CONFIG.SYS CONFIG.IBM, and press Enter.
b. Type copy AUTOEXEC.BAT AUTOEXEC.IBM, and press Enter.
2. Use a text editor such as EPM or E from the OS/2 prompt. The following
instructions use the EPM editor. Type EPM CONFIG.SYS, and press Enter.
3. Check for the lines that refer to the device driver.
DEVICE=C:\OS2\BOOT\OS2CDROM.DMD /Q
IFS=C:\OS2\BOOT\CDFS.IFS /Q
DEVICE=C:\OS2\MDOS\VCDROM.SYS
BASEDEV=IBMIDECD.FLT
If these lines are not present, add them.
4. Save any changes and exit the CONFIG.SYS file.
5. Check that the device drivers are on the hard disk drive and in the correct
directory.
C:\OS2\BOOT\OS2CDROM.DMD
C:\OS2\BOOT\CDFS.IFS
If the drivers are not present, reinstall them. See the READ.ME file on the
40X-17X Internal IDE CD-ROM Drive Option Diskette for more information.
The CD-ROM is not recognized by the operating system or the drive performs
erratically.
Some computers, such as IBM PS/ValuePoint models 6472, 6482, 6484, 6492, and
6494, have a compatible and a high performance mode for mass storage devices.
Normally, the CD-ROM drive functions better under high performance mode.
However, if your drive is not functioning properly in that mode, you might need to use
compatible mode.
Check the configuration-setup information for your computer.
1. Access your configuration utility program.
2. Select Devices.
3. Scroll down to the Mass Storage Devices section.
4. Mass Storage Devices contains the entries Primary IDE Mode and Secondary IDE
Mode. These entries are used to set the performance mode of each IDE port. Set
the mode to Compatible for the port on which you installed your CD-ROM
drive.
Other IBM and non-IBM computers might have similar settings. Check to see if your
BIOS or configuration-setup utility provides for compatible and high performance
modes for IDE performance. For these computers, use the compatible mode for slower
IDE devices, such as this CD-ROM drive. Refer to the documentation that comes with
Part 3: Appendixes 3-11
