2)  INSTALLATION PROCESS

     The hard disk installation program, INSTALL.COM, will copy 
     the necessary files from OPTi Install diskette(s) into your 
     hard disk. Please follow the installation procedures 

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

     1. Place the disk labeled "OPTi 82C930 Installation" in 
        Drive A (could be drive B).

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

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

     OR

     1. Copy all the files from installation floppy disk(s) to local
        or make your own installation CD.

     2. Change the drive and directory if the current one does not
        match.

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


     INSTALL.COM and SNDINIT.EXE will do the followings for you: 
 
     a.) Create the directory \OPTI930 (assuming: default) 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 with INSTALL.COM to the OPTI930 directory 
         and Windows directory respectively if you set "WIN31" and
         "WINAPP" in DISK1 file to be "YES". If not, only the 
         DOS-related files will be copied to OPTI930 directory. 

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

         - DEVICE=C:\OPTI930\CDSETUP.SYS /T:S /P:340 
           (assuming SONY CD-ROM)
           DEVICE=C:\OPTI930\SLCD.SYS /D:MSCD000 /B:340

         In AUTOEXEC.BAT:

         - PATH=C:\OPTI930 (appended)
           SET SOUND16=C:\OPTI930
           C:\OPTI930\SNDINIT /B
           SET BLASTER=A220 I5 D1 T4


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

     - SNDINIT /?


4)  DOS 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 SUPPORT

     [for the DOS users]

     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 MAD16 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:[addr] 
            /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:\OPTI930\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 Window 95  

     In this release, our implemenatation has been changed to provide 
     Demand-Driven DOS Box Game Support. There is only one DOS box
     that can own the audio device at one time.

     !! Notes !!
     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. DOOM is
        one of those games failed in DOS BOX. Windows 95 provides
        much better DOS BOX support and DOOM is OK with Windows 95
        DOS BOX.
