If this line is not present, add it.
5. Save the CONFIG.SYS file and exit.
6. Type E (or your editor name) AUTOEXEC.BAT and press Enter.
7. Check for the following device driver line.
LH C:\MSCDEX /D:IBMCD1 /M:1
If this line is not present, add it.
8. If the Windows screen automatically opens when you start your
computer, check that the line
LH C:\MSCDEX /D:IBMCD1 /M:1
comes before the line that starts Windows (WIN). If not, move
the MSCDEX statement above this line in the file.
9. Save the AUTOEXEC.BAT file and exit.
10. Make sure that the device drivers are on the hard disk and are
displayed in the correct directory, as shown.
C:\IBMIDECD.SYS
C:\MSCDEX
If the device drivers are not present, reinstall them. See the
READ.ME file on the IBM 2X/4X/24X CD-ReWritable Drive
Option Diskette for more information.
The CD-ReWritable drive 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 compatible and high performance modes
for mass storage devices. Normally, the CD-ReWritable drive
functions better under the 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 have installed your
CD-ReWritable 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-ReWritable drive. Refer to the documentation that
comes with your computer for additional details on selecting IDE
performance modes. Many older computers will not have a selection
of IDE performance modes.
