SUMMARY
Microsoft Windows supports CD-ROM drives. The following explains how to configure a CD-ROM drive for operation with Windows.



Steps to Configure a CD-ROM Drive for Windows 3.0, 3.0a
 Edit the SYSTEM.INI file with a text editor such as Notepad. Locate the [386enh] section and add the following:

device=LANMAN10.386

 Use the Windows EXPAND.EXE utility to expand the file LANMAN10.386 from the Windows disks into the Windows SYSTEM subdirectory. Restart Windows.

Steps to Configure a CD-ROM Drive for Windows 3.1
During Setup, if MSCDEX is loaded, then Windows 3.1 automatically installs LANMAN10.386. If you are using a version of MSCDEX greater than version 2.1, then you should remove the line

device=LANMAN10.386

from your SYSTEM.INI's [386enh] section.

General Information About Running a CD-ROM with Windows
MSCDEX.EXE, the terminate-and-stay-resident (TSR) program that implements the Microsoft CD-ROM Extensions for MS-DOS, provides access to CD-ROM drives. MSCDEX.EXE appears to MS-DOS to be a network redirecter; it uses the same interface to MS-DOS as Microsoft LAN Manager.

LANMAN10.386 causes calls from MS-DOS to a redirecter (including LAN Manager or MSCDEX.EXE) to be inside an enhanced-mode-critical section. This is required for these products to work correctly with Windows running in enhanced mode.

Note that the flowchart on page 21 of the version 3.1 &quot;Microsoft Windows Resource Kit&quot; guide incorrectly uses the term LANMAN10.DOS where LANMAN10.386 is intended.
