SUMMARY

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

MORE INFORMATION

Steps to Configure a CD-ROM Drive for Windows 3.0, 3.0a

  1. Edit the SYSTEM.INI file with a text editor such as Notepad.

  2. Locate the [386enh] section and add the following: 

          device=LANMAN10.386

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

  4. 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 "Microsoft Windows Resource Kit" guide incorrectly uses the term LANMAN10.DOS where LANMAN10.386 is intended.
