IBM 09N4076 - Manual (Page 48)

7. Restart the computer.
If the device icon is still not present, check cable connections, device jumper settings,
and resolve any existing conflicts.
You cannot access the CD-RW drive (DOS and Windows 3.x), or the drive icon
(Windows 3.x) does not display.
Your CD-RW drive device driver might not be loaded or cannot be found. Before
checking the CONFIG.SYS and AUTOEXEC.BAT files, make a backup copy of these
files in a preferred directory.
1. At the DOS prompt:
a. Type x:copy CONFIG.SYS CONFIG.IBM, where x is the directory drive letter
and press Enter.
b. Type x:copy AUTOEXEC.BAT AUTOEXEC.IBM, where x is the directory drive
letter and press Enter.
2. Use a text editor such as E or Edit. At the DOS prompt, type E (or your editor
name) CONFIG.SYS and press Enter.
3. Insert the following line at the top of the CONFIG.SYS file to allow for more
than five drive letters, if needed.
lastdrive=z
4. Check for the following device driver line.
DEVICEHIGH=C:\IBMIDECD.SYS /D:IBMCD1
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
