If the device drivers are not present, reinstall them. See the READ.ME file on
the IBM Option Diskette for more information.
The computer does not recognize the CD-RW drive after the device drivers are
loaded (DOS and Windows 3.X).
Check for incompatibilities among the CD-RW drive device driver and other device
drivers or other hardware in your computer. Create a System Diskette with minimum
CONFIG.SYS and AUTOEXEC.BAT system files.
1. Before creating special CONFIG.SYS and AUTOEXEC.BAT files, make a
backup copy of these files in a preferred directory.
Type x:copy CONFIG.SYS CONFIG.IBM where x is the directory drive letter
and press Enter.
Type x:copy AUTOEXEC.BAT AUTOEXEC.IBM where x is the directory drive
letter and press Enter.
2. Create a System Diskette and copy the device drivers onto it using the following
instructions.
a. Insert a blank diskette into the diskette drive.
b. At the DOS prompt, type format a: /s and press Enter. The /s parameter
creates the System Diskette. Follow the instructions on the screen.
c. When the format process completes, copy the C:\IBMIDECD.SYS and
C:\MSCDEX files from the hard disk to the System Diskette.
d. Using a text editor, create a minimum CONFIG.SYS system file on the
System Diskette to support only a CD-RW drive. The following procedure
uses the E text editor to create the CONFIG.SYS file from the A prompt.
1) Type e config.sys and press Enter.
2) In the editor, type lastdrive=z and press Enter.
3) Type device=a:\ibmidecd.sys /d:ibmcd1 and press Enter.
4) Save the CONFIG.SYS file and exit from the editor.
e. Using a text editor, create a minimum AUTOEXEC.BAT system file on the
System Diskette to support only a CD-RW drive. The following procedure
uses the E text editor to create the AUTOEXEC.BAT file from the A
prompt.
1) Type e autoexec.bat and press Enter.
2) Type a:\mscdex /d:ibmcd1 /m:1 and press Enter.
3) Save the AUTOEXEC.BAT file and exit the editor.
3. Turn off the computer and check that the System Diskette is in the diskette drive.
4. Restart the computer (the computer will start up from the System Diskette).
