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 "REVEAL SC400 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 \SC400 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 SC400 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:\SC400\CDSETUP.SYS /T:S /P:340 
	  (assuming SONY CD-ROM)
	  DEVICE=C:\SC400\SLCD.SYS /D:MSCD000 /B:340

	In AUTOEXEC.BAT:

	- PATH=C:\SC400 (appended)
	  SET SC400=C:\SC400
	  C:\SC400\SNDINIT /B
	  SET BLASTER=A220 I5 D1 T4

	In SYSTEM.INI:

	- [drivers]
	  WAVE=SC400.DRV
	  AUX=SC400.DRV
	  MIDI=SC400.DRV
	  MIXER=SC400.DRV
	  MIDI1=MPU401P.DRV

	  [386Enh]
	  DEVICE=VSC400.386

	  SC400.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.

	  VSC400.386 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 SC400 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:\SC400\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.
