Objective:
*********

This file provides last minute information on the product that are unable 
to make it to the printing of the manual. It also serves as a better 
understanding in the installation process of WPI multi-language support 
installation software. Please read this file thouroughly before installing 
the CD-ROM drive.

MSCDEX NOTE :
*************

This version will copy MSCDEX.EXE from User's hard drive to subdirectory,
"\CDROM".If MSCDEX is not available, please obtain a licensed copy from
Microsoft DOS 5.00 or above.


Installation Process:
********************

(1) Change the DOS prompt to that of the floppy drive.
    Example,
               A:[Enter] (or B:[Enter])

(2) To begin installation, type INSTALL [Enter] at the DOS prompt.
    A screen will pop up.

(3) To install using English language, simply press ENTER at YES 
    option (YES option will be automatically highlighted by default).

(4) To install using other languages (not Japanese), move the highlight 
    to the appropriate language and press ENTER. The text will change 
    to the selected language. Proceed to start the installation by 
    pressing ENTER. 

(5) If Japanese DOS is installed, the startup screen will automatically
    be Japanese text. Proceed with the installation in Japanese by 
    pressing ENTER (take note of the cursor's position). Japanese language
    is supported only if Japanese DOS is installed.

(6) Follow the instructions on the screen till installation is completed.



Additional Note For CDD-820 and above :
***************************************
CDD-820 and above support DMA (Direct Memory Access). This feature enables 
the transfer of data between the CD-ROM drive and system memory without 
the intervention of the CPU. This eases the CPU to process other timing 
critical jobs like decoding of full-motion video and audio. However, the 
motherboard/BIOS must be able to support DMA transfer before CDD-820 and 
above can make use of it. 

To turn on the DMA transfer, edit CONFIG.SYS file as follow :
    DEVICE=C:\DOS\EMM386.EXE
    DEVICE=C:\CDROM\WCD.SYS /D:WP_CDROM /PM
The /PM option is used to enable PCI Bus Mastering for DMA transfer. 
(For Triton Chip-Sets only).

Note that EMM386.EXE is neccessary for WCD.SYS to enable DMA transfer in DOS
environment. This is because DMA requires a Virtual Memory Conversion  
to be performed by EMM386.EXE. This function is supported in Windows 3.x by 
default, hence EMM386.EXE is not neccessary for user who uses Windows only.
 

For usage of multiple IDE CD-ROM device drivers under CONFIG.SYS,     
please take note of the following options:

    DEVICE=C:\CDROM\WCD.SYS /D:WP_CDROM /N:pm 
    {for Primary Master detection only}

    DEVICE=C:\CDROM\WCD.SYS /D:WP_CDROM /N:ps 
    {for Primary Slave detection only}

    DEVICE=C:\CDROM\WCD.SYS /D:WP_CDROM /N:sm 
    {for Secondary Master detection only}

    DEVICE=C:\CDROM\WCD.SYS /D:WP_CDROM /N:ss 
    {for Secondary Slave detection only}

Default setting does not include /N option, which means the driver
will detect all the Primary and Secondary IDE CD-ROM drives.

The /N option can be used to specify any combination on the same line.
e.g. 
    DEVICE=C:\CDROM\WCD.SYS /D:WP_CDROM /N:ps /N:sm
    {for Primary Slave and Secondary Master detection only}

(Note : The /N option is only supported by WCD.SYS ver 2.31 and above.)
