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.

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.
