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.

     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 in your floppy disk to the OPTI930 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:\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

	 In SYSTEM.INI:

	 - [drivers]
	   WAVE=SND930.DRV
	   AUX=SND930.DRV
	   MIDI=SND930.DRV
	   MIXER=SND930.DRV
	   MIDI1=MPU401P.DRV

	   [386Enh]
	   DEVICE=V930D.386

	   SND930.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.

	   V930D.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)  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.

     [For the Windows Users]

     The Mixer utility provided by OPTi could be used as Karaoke
     control tool. The MIC Level Control is designed to adjust the
     Direct Microphone Output Volume. Move the Level to the bottom 
     will shut off Mic output. Please adjust the Master Level as 
     well to get the best microphone output level.


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 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.

     !! 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.
