0.  What's NEW in this release

         - Support OTHER CD drives which not listed in our installer's CD
                drive list. OTHER IDE, Sony compatible and Panasonic compatible
                are those which we are not aware of at the time software release
                but actually could be interfaced with our sound cards. What
                the software does, when OTHER is selected, is to setup the
                CD-ROM interface of the sound card. The CD driver installation
                then has to be taken care by you after the audio software 
                installation is done.
         - Maintain Green PC feature after IRQ re-selection
         - Reset FM MIDI device during INIT

2.  INSTALLATION PROCESS

         The hard disk installation program, INSTALL.EXE, will copy 
         the necessary files from OPTi Installation disk into your hard 
         disk. Follow the following procedure to install the software:

         !!! Note: For Windows users, please exit from Windows and run
                                the installation from DOS.

         (Assuming you are using floppy drive A, and you wish to install
          to hard disk drive C)

         1. Place the disk labeled "SOUND IMAGE 16 Installation" in
                 Drive A.

         2. Type a: and press ENTER to change to Drive A.

         3. Type install and press ENTER to begin the installation.

         INSTALL.EXE will do the followings for you: 
         
         a.) Create the directory \SDIMAGE in your hard disk drive.

         b.) Prompt you for CD-ROM and sound card options so that after
                  you have finished the installation and have rebooted your 
                  machine, you will be ready to use the sound card.

         c.) Copy the files in your floppy disk to the SDIMAGE directory and
                  Windows directory respectively.

         d.) Update your CONFIG.SYS, AUTOEXEC.BAT and SYSTEM.INI files
                  In CONFIG.SYS, the following will be added:

                  - DEVICE=C:\SDIMAGE\CDSETUP.SYS /T:S /P:340
                         (assuming SONY CD-ROM)
                         DEVICE=C:\SDIMAGE\SLCD.SYS /D:MSCD000 /B:340

                  In AUTOEXEC.BAT:

                  - PATH=C:\SDIMAGE (appended)
                         SET SOUND16=C:\SDIMAGE
                         C:\SDIMAGE\SNDINIT /B
                         SET BLASTER=A220 I5 D1 T4

                  In SYSTEM.INI:

                  - [drivers]
                         WAVE=SND16.DRV
                         AUX=SND16.DRV
                         MIDI=SND16.DRV
                         MIXER=SND16.DRV
                         MIDI1=MPU401P.DRV

                         [386Enh]
                         DEVICE=VSND16D.386

                         SND16.DRV is the Base driver comprising WAVE, MIDI,
                         MIXER and AUXILIARY audio services.
                
                         MPU401P.DRV is the device driver for MPU-401 Wave Table 
                         Synthesis interface which requires a MPU-401 compatible 
                         device attached to the MIDI Input/Output port or the Wave 
                         Table connector on board the sound card.

                         VSND16D.386 is the Virtual Device driver for Windows 
                         Enhanced Mode.


3.  GETTING HELP ABOUT SNDINIT.EXE
 
         You can issue the following command to get information 
         about sndinit.exe:

         - SNDINIT /?


4.  VOLUME CONTROL TSR PROGRAM

         The volume control memory resident program, VOLTSR.EXE, allows
         you to change volume using hot keys while you are in a DOS 
         application. The hot keys are:

                  Ctrl-Alt-U      Raises the volume
                  Ctrl-Alt-D      Lowers the volume
                  Ctrl-Alt-M      Mute

         For example, pressing the CTRL, ALT, and U keys will raise 
         the volume.

         You need to load the TSR before you can use it. To load the TSR,
         type VOLTSR at the DOS prompt.


5.  KARAOKE PROGRAM

         The Karaoke.exe program allows user to control the input volume
         of the microphone on the fly with "HOT KEYS." Before using 
         Karaoke, the VOLTSR.EXE program must be successfully loaded
         and running.

         To enable Karaoke Mode, type: "KARAOKE ON" at the DOS prompt.

         To increase MIC input, use: Ctrl-Alt-PageUp
         To decrease MIC input, use: Ctrl-Alt-PageDown

         To disable Karaoke Mode, type: "KARAOKE OFF" at the DOS prompt.


6.  CD-ROM Interface Setup Device Driver

         The CD-ROM Setup Device Driver is called CDSETUP.SYS. This 
         driver sets up the interface of your CD-ROM to the SOUND IMAGE 16
         sound card. Each time you change or add a CD-ROM to your sound
         card. The line "DEVICE=CDSETUP.SYS..." will be added to the
         first line of your CONFIG.SYS file before the CD-ROM device
         driver line. CDSETUP.SYS is defined as follows:
         
         DEVICE=[drive:]\[directory]\CDSETUP.SYS /T:[M/S/P/I/X] /P:[address] 
                          /I:[IRQ] /D:[DMA]  

         [drive] = drive where you have the driver installed
         [directory] = directory where the driver is located
         [M/S/P/I/X] = M stands for Mitsumi
                                                S stands for SONY
                                                P stands for PANASONIC
                                                I stands for IDE drive
                                                X stands for disabled

         [address] = Port address for CD-ROM (320, 330, 340, 360)

         [IRQ] = Interrupt number (5,7,9,10,11)

         [DMA] = DMA channel (0, 1, 3)

         For example, the following line sets up the interface for a 
         Mitsumi CD-ROM:

         DEVICE=C:\SDIMAGE\CDSETUP.SYS /T:M /P:340 /I:10

         If you did not specify the /I or /D options, CDSETUP will 
         automatically choose the default setting for the CD-ROM type 
         your have specified.

         - For Mitsumi, the IRQ is 10 and DMA is disabled.
         - For SONY, they are both disabled.
         - FOR PANASONIC, they are both disabled.

         For IDE drive, you need to just specify the /T:I option. 
         Specifying any other option in addition to this will be ignored.
         The I/O Port and Interrupt for IDE is located at 170H and Int 15.


7) Run DOS games in Windows

         Our implementation is designed for those DOS games which have
         icons in Windows and run in full screen DOS and close after 
         finished. When multiple DOS boxes are open, only the first 
         DOS box owns the audio device. DOS Box support could be very 
         complicated, we have to concentrate our implementation only on 
         those features most useful to the general users. We recommend 
         to run game or play audio in DOS box only one at a time. 
         Close the DOS box which owns the device will return the device 
         to Windows. Then you can play audio in Windows or run another 
         DOS game.

         !! Note !!
         a) Sometimes, the Setup of the PIF file of a DOS game is crucial. 
                 To make a game work effectively under Windows, you probably 
                 have to try a few alternative options through PIF editor.
         b) Not all the DOS games can run in Windows' DOS BOX. Some of 
                 them just don't run because of system restrictions.
