CD-ROM EXTENSIONS FOR WINDOWS
=============================

 CorelSCSI version 1.2 uses CORELCDX.COM for its CD-ROM
 extensions. Previous versions of CorelSCSI used MSCDEX.EXE.
 For more information about CORELCDX.COM, read the README.UTI
 README file after you've installed CorelSCSI.

 If you're using a CD-ROM drive with Windows 3.0 or later,
 you require either CorelCDX version 1.0 or MSCDEX. These programs
 provide the CD-ROM extensions required to read the CD format.

 Note: If you've already installed MSCDEX, the installation adds the
       CorelCDX code to your system, but doesn't replace MSCDEX in 
       your CONFIG.SYS file. 

 Several versions of MSCDEX are available. If you use
 a version of MSCDEX prior to 2.20, your Windows
 README.TXT files recommend that you add the following
 line to the [386Enh] section of your SYSTEM.INI file
 before using CD-ROM extensions:

      device=LANMAN10.386

 If the expanded LANMAN10.386 file isn't located in your Windows
 directory, you can copy it from your Windows version 3.0 diskettes.

 To copy and expand the LANMAN10.386 file

 1. Copy EXPAND.EXE from your Windows diskettes to your
    Windows directory.

 2. Enter the following at the DOS prompt to expand and copy 
    the LANMAN10.386 file to your Windows directory:

       EXPAND A:LANMAN10.386 C:\WINDOWS

    where A is the drive in which you've inserted the Windows 
    diskette that contains the LANMAN10.386 file. C:\WINDOWS is the 
    default drive and directory where Windows is stored.

 If you use MSCDEX version 2.20 or later, remove the 
 "device=LANMAN10.386" line -- it may cause some CD-ROM drives
 to time-out and fail.

 Before you start Windows, activate the drive. To activate the drive, 
 type the following at the DOS prompt:

      dir <drive>:

 where "<drive>" is the drive letter for the CD-ROM drive.


EXPANDED MEMORY AND CORELCDX
----------------------------

 If you're using CorelCDX and an expanded memory manager such 
 as EMM386.EXE, the installation adds the following switch to the 
 CORELCDX device statement in the AUTOEXEC.BAT file:

      /E:3

 This switch places CorelCDX code, data, and cache buffers into 
 expanded memory. Only a minimal amount of code is left in 
 conventional memory.

 In rare cases, this default switch may cause problems when you try to
 access the CD-ROM drive. Some applications loaded in expanded
 memory may create memory conflicts when trying to access cache 
 buffers that are also loaded in expanded memory. If you experience 
 problems, replace the /E:3 switch with the following:

      /E

 This switch loads only the cache buffers into expanded memory. 


UNSUPPORTED MSCDEX COMMAND LINE SWITCHES
----------------------------------------

The following MSCDEX command line switches
are not supported under CorelCDX version 1.0.

      /V - verbose mode to display information during boot up

      /S - patch to allow sharing of CD-ROM drives on MS-NET based 
           servers

      /K - force selection of shift-JIS Kanji Supplemental Volume 
           Descriptors

 For more information about supported MSCDEX command line switches, 
 read README.UTI after you've installed the software.
