     I.  General
     The CD-ROM packet comes with an installation utility. This installs
     the nessary CD-ROM drivers needed by your CD-ROM drive to interface
     with your PC.

     The drive installation diskette includes the following files:

     README.TXT  -- User's guide
     INSTALL.EXE -- CD-ROM installation program
     CDTECH.SYS -- CD-ROM device driver
     UDMA.TXT -- Ultra DMA insturction

     II.  Environments

     Hardware Requirements
     1. IBM PC/AT or compatible (80386-base system recommended)
     2. Minimum EGA graphic display (VGA recommended)
     3. Minimum 2M RAM recommended

     Software Requirement
     1. Microsoft Windows 3.1 or later
     2. MS-DOS version 5.0 or later
     3. MS-DOS CD-Extension (MSCDEX 2.21) or later

     III. The Procedures of Installation

     To install CD-ROM device driver, please follow the steps below:

     1. Insert the installation diskette in your system's 3.5-inch floppy
        disk drive.

     2. Change the directory to that of your floppy disk drive, and type
        the following at the DOS prompt:

              INSTALL <Enter>

     3. Follow the screen instructions to complete the installation.

     4. Reboot system to activate the driver.

     In general, you can just continually press the Enter key to install
     the default settings. A directory (default C:\CDROM) containing the
     CD-ROM drivers is created during installation. Your AUTOEXEC.BAT
     and CONFIG.SYS files are also modified to include the following lines:


              C:\DOS\MSCDEX.EXE /D:MSCD001 /M:10

     IV.  Changing Settings

     To reconfigure the settings of the CD-ROM driver, use a text editor,
     such as EDIT.COM, to modify the previous two command lines in CONFIG.SYS
     and AUTOEXEC.BAT and then restart your computer to activate it.

     Changing the CONFIG.SYS file
     DEVICE=<path>\CDTECH.SYS /D:<device_name>

     The <device_name> is the name MSCDEX will use to find the device
     driver. The maximum length of <device_name> string is 8 characters.

               DEVICE=C:\CDROM\CDTECH.SYS /D:MSCD001 

     Changing the AUTOEXEC.BAT file
     MSCDEX /D:driver [/E] [/K] [/S] [/V] [/L:letter] [/M:number]

               C:\DOS\MSCDEX /D:MSCD001 /M:10

     For more information, you can refer to the MS-DOS online help for MSCDEX
     by typing HELP MSCDEX.
