Software Installation
=====================

 For system to configure the CD-ROM drive and user to get access
 to it, you have to properly install the CD-ROM device driver on
 your system.

 The installation diskette includes the following files:

 install.exe  -- CD-ROM device driver installation program
 actcd.sys    -- CD-ROM device driver software
 readme.txt   -- Detailed information regarding installing CD-ROM
                 drive to your system

 Installation Procedure
 ----------------------
 1. Boot up your computer in DOS environment instead of Windows.

 2. Insert the installation diskette to floppy drive A or B.

 3. At A:\ or B:\ type 'INSTALL' then press 'ENTER'.

 4. If MSCDEX.EXE has not found in drive C:, please enter the full path
    which contains MSCDEX.EXE file to the dialog box and press 'ENTER'.
    Otherwise, press ESC to exit installation program.

 5. The user must assign a disk drive and directory for device driver.
    The default directory for device driver software is C:\CdExpert.
    If you want to use the default directory, simply press 'ENTER'.
    If you want to change the device driver directory, input the full path
    name to the dialog box and press 'ENTER'.
    Installation program will copy device driver software and readme file
    from the diskette to the directory.

 6. Use the left and right arrows to select the system files modificaion
    options.

    If you select Yes, installation program will backup config.sys and
    autoexec.bat to config.atc and autoexec.atc. It will also modify the

    If you select No, no change will be made. Please manually modify your
    config.sys and autoexec.bat files.

 7. Press any key to exit the installation utility.

 8. When finished, please remove the diskette from floppy drive and
    reboot to activate your CD-ROM drive.

 During system reboot, check the following message to assure that the

Device Driver Parameters
========================

 Adding options to config.sys
 ----------------------------

 Device=<path>\actcd.sys /D:xxxxxxxx [/P:xxx,yy] [/DMA:nn] [/UDMA:nn] [/V]

 /P:xxx,yy
  xxx specifies the IO port address in hex. xxx=1F0, 170, 1E8, or 168
  yy specifies the IRQ number in decimal. yy=14, 15, 10, 11, or 12

 /DMA:nn
  It enables Bus Master transfer function with mode n where nn=0 to 2

 /UDMA:nn
  It enables Ultra DMA transfer function with mode n where nn=0 to 2

 /V
  Verbose mode specifies whether complete setup information is printed to
  the screen.

 Example:
  Device=C:\CdExpert\actcd.sys /D:mscd001 /P:1F0,14 /DMA:2

 *** Please do not add /P option if you are not familiar with IO port
     address and IRQ number.
 *** The DMA and UDMA mode can only work on PC or PC-compatibles with
     Intel Triton chipset employed.

<< Trouble shotting >>
Q1: "**Error: IDE CD-ROM device driver NOT installed" message is displayed
    during loading the device driver.
    -------------------------------------------------------------------------
A1: Please make sure that power cable and I/F cable are properly connected.
A2: Please make sure that there is no conflict with IDE card address(primary,
    secondary, tertiary etc.) and/or interrupt number.
A3: Please make sure that MSCDEX.EXE is loaded from autoexec.bat. If this
    file is not loaded, checkout the directory which contains MSCDEX.EXE and
    run install.exe again to input the correct directory for MSCDEX.EXE.
A4: In case that CD-ROM drive is daisy-chained with hard disk drive, please
    make sure that hard disk drive jumper is set to MASTER and CD-ROM's to
    SLAVE. Please refer to the installation manual for CD-ROM jumper setting.

Q2: CD-ROM drive will not be recongnized by the system when MSCDEX.EXE is
    loaded.
    ------------------------------------------------------------------------
A:  Device name specified in config.sys and autoexec.bat may not be matching.
    Please make sure that each statement has "/D:mscd001".

Q3: system does not recognize the CD-ROM drive with error message "Not enough
    drive letters".
    ----------------------------------------------------------------------------
A:  There may be no more drive lstter available. Please add or edit "LASTDRIVE"
    statement to CONFIG.SYS file so that the last drive equals one more than your
    current last drive.
        Example:
                Current
                   A:FDD
                   B:FDD
                   C:HDD
                   D:HDD
                New
                   A:FDD
                   B:FDD
                   C:HDD
                   D:HDD
                   E:CD-ROM --> "LASTDRIVE=E"
