README.TXTfile
The README.TXT file on the installation disk contains the most updated
information after the printing of this installation guide. Please read it be-
fore you start the installation procedure.
Changesto AUTOEXEC.BAT
The installation program will add several changes to your AUTOEXEC.BAT
file. You can choose to have INSTALL make these changes for you, or
store the changes in a separate file called AUTOEXEC.MAD.Then you
must edit the AUTOEXEC.BAT and make the changes yourself.
Your path statement will have the C:\OPTi930 subdirectory added to it
(with the PATH %PATH%; C:\OPTi930 command).
The AUTOEXEC.BAT file shall have the following added :
Syntax: Example:
SET SOUND16=<DRIVE:\PATH>SET SOUND16=C:\OPTI930
<DRIVE:\PATH>\SNDINIT /B C:\OPTI930\SNDINIT /B

Syntax: DEVICE=<drive:\path>\CDSETUP.SYS /T:n /P:n
Example:DEVICE=C:\OPTI930\CDSETUP.SYS/T:I P:170

16-Bit Sound Pro 9
CD-ROM Configuration
You must set the exact hardware settings that match to your CD-ROM
drive. For IRQ, DMA channel, and I/O base address.
Testing the HOT-235 Sound
In a system, it is important that you test the HOT-235 sound card when
you are in the installation program. This will insure that your settings are
correct and working properly. If you do not hear any sound, you can try
and adjust the volume. If you still do not hear any sounds, you will need
to make sure your settings are correct. Check the Sound Blaster or Win-
dows Sound System settings first. If your system locks up during the sound
test, you will need to reboot, run the SNDINIT.EXE program, and check
your settings.
Testing and Re-Configuring the HOT-235 Sound Card
You can run the SNDINIT.EXE program at anytime to make changes to your
HOT-235 configuration. When re-configuring the HOT-235, you can use
the following parameter lines:
SNDINIT /B Runs the SNDINIT program using the values speci-
fied in the SOUND16.CFG configuration file.
SNDINIT /? Displays help information to explain how to use
SNDINIT.
SNDINIT Runs the SNDINIT program to let you change your
HOT-235 configuration. You will see the main con-
figuration screen you had when you first setup the
HOT-235 with the installation program.

10 16-Bit Sound Pro
VOLTSR.EXE -- Volume Control Utility
The installation disk comes with an TSR volume control utility,
VOLTSR.EXE. You can use this utility to control the volume in the DOS
environment. Load the program by typing VOLTSR at DOS prompt. Then
use the following hot keys to change the volume:
CTRL-ALT-U Raise the volume
CTRL-ALT-D Lower the volume
CTRL-ALT-M Mute the volume
To remove the program from the memory, type VOLTSR/U at the DOS
prompt.
Some games do not allow this TSR to take effect. In this case, you will not
be able to access these hot keys and use the keyboard to control the vol-
ume. You can exit the game, and run SNDINIT.EXE to adjust the volume
or use an external amplifier with its own volume control adjustments.
KARAOKE.EXE -- Karaoke Utility
The installation disk contains a karaoke utility KARAOKE.EXE The pro-
gram is a TSR program that redirects input from the microphone input line
directly to the Speaker Out line. This will let you talk or sing directly to
your speakers.
To run the program, enter KARAOKE ON at the DOS prompt. This will
make the program resident in memory and will begin redirecting your
microphone input to your speaker output. To turn it off, enter KARAOKE
OFF at the DOS prompt. This will turn off the KARAOKE program and
remove it from memory.
When you use KARAOKE with the VOLTSR program, you can adjust the
microphone volume with the following keys:
CTRL-ALT-PgUp Raises the volume
CTRL-ALT-PdDn Lowers the volume

CD-ROM CONFIGURATION
This portion will help you set up your CD-ROM to work properly with
the HOT-235. This section will explain how to set up the CD-ROM
using the SNDINIT.EXE configuration program.
The HOT-235 supports all IDE CD-ROM drive models. You can configure
and set up these CD-ROM drives when you first set up the HOT-235 using
the INSTALL.EXE program, or later with the SNDINIT.EXE program.
Before proceeding, make sure you have successfully installed your CD-
ROM drive hardware into your computer system as well as the CD-ROM
drive’s device driver and related software.
The following steps will help you set up your CD-ROM drive with the
SNDINIT.EXE program.
1. Run SNDINIT.EXE and choose Configure.
2. Select CHANGE OPTIONS in the CD-ROM Interface section.
3. Select the correct CD-ROM from the CD-ROM Drive List and click
"OK".
A line similar to the following has been added :
DEVICE=C:\OPTI930\CDSETUP.SYS /T:I
4. You must now exit the program and reboot your computer for the
settings to take effect.
If you decide to change your current CD-ROM options, you need to
run SNDINIT.EXE again. Each time you make changes to your con-
figuration, your CONFIG.SYS file must be updated again.
The SNDINIT.EXE program will only make changes to the Config.sys
line that begins with:
DEVICE=C:\OPTI930\CDSETUP.SYS . . .
If you have changed your CD-ROM drive, your CD-ROM manufac-
turer will have recommended changes for its own CD-ROM device
drivers that you must follow. Refer to your CD-ROM drive’s user
manual for more information.

16-Bit Sound Pro 13
Installing the MSCDEX Driver
Your CD-ROM will require that the proper MSCDEX driver is loaded on sys-
tem boot-up. During installation, the HOT-235 installation program will take
several steps to insure that the proper MSCDEX is used for your system.
1First, the HOT-235 installation program will look at your Autoexec.bat
file for an existing MSCDEX driver. If it finds it it, will use it.
2If it doesn't find it there, it will scan your hard drive to find the
MSCDEX.EXE program. Usually this will be found with you DOS op-
erating system programs. If the HOT-235 installation program finds
the MSCDEX.EXE program it will use it. If more than one copy of
MSCDEX.EXE exist on your system, the HOT-235 installation program
will display all known files on your system, and ask you to select the
one you want to use.
3The HOT-235 comes with three MSCDEX drivers. If MSCDEX.EXE is not
found on your system, the HOT-235 installation program will check
your DOS version (DOS 5.0, 6.0 and 6.2),then copy and install the
MSCDEX.EXE program which will work best with your system.
4If the HOT-235 installation program determines that your DOS ver-
sion is earlier than 5.0, it will request that you use the MSCDEX pro-
gram that came with your CD-ROM drive (available from your CD-
ROM manufacturer). The following line will be added to your
autoexec.bat file:
REM C:\OPTI930\MSCDEX.EXE
When you copy the proper MSCDEX.EXE program that works with your
CD-ROM into the C:\OPTI930 subdirectory, edit the above line in your
AUTOEXEC.BAT file by removing the word "REM"so that the line looks
as follows:
C:\OPTI930\MSCDEX.EXE
The proper MSCDEX.EXE program will then be loaded when you re-
boot your system.

WINDOWSCONFIGURATION
During the Software installation process, the HOT-235 sound card in-
stallation program added Windows sound drivers to your system. This
section will describe how to change the DMA channel, IRQ, I/O Port
Address, and Advanced Settings of the HOT-235 in Windows 3.1. To
change settings under Windows, please follow the steps below:
1Start Windows.
2Select the Main file group.
3Click on the Control Panel icon.
When the Control Panel appears,
Click on the Drivers icon.
4When the Drivers Dialog Box ap-
pears, highlight OPTi HOT-235 Au-
dio Driver (OPTi 82C930 Audio
Driver), then double click the Setup
button.
5The HOT-235 sound card Audio
DeviceDriver ConfigurationDialog Boxwill
appear. Make the necessary changes by
clicking on the selections.
6Enable Full Duplex : TheEnableFull Du-
plex option allows you to select two DMA
channels to enable simultaneous play-
back and recording. When disabled, the
DMA channel will operate as both
playback and recording, and you can do
either digital wave recording or playback
at the same time.
7MPU-401 Configuration : The Enable MPU-401 option allows you
to use the wavetable synthesis connector for advanced sound syn-
thesis. The I/O Add. and IRQ settings can only be modified after the
option is enabled.

16-BitSoundPro 15
8AdvancedSettings :
If you wish to modify the advance settings, click on Advance
Settings and a Window will appear. Make the necessary changes
and click OK.
Boost for Microphone Recording
Enables you to enable a 20dB boost to the recording level for the
microphone input (MIC IN). This allows you to compensate for less
powerful microphones and increase the recording signal.
UseSingle Mode DMA
Your computer system may
support both Single Mode DMA as
well as Demand Mode DMA.
Demand Mode DMA provides a
more efficient means of trans-
ferring chunks of data between
memory and a device. However, if your system does not support
Demand Mode DMA, you must select Single Mode DMA instead.
DMA Buffer Size
Setting the DMA buffer size tells the CPU how much data to transfer
between memory and a device at one time. If you specify a larger
size, it allows the CPU to complete the transfer of data faster,but
increases the memory consumption. The default size should be 32
Kilobytes (32KB). If you decide to change the buffer size, be sure to
make it multiples of 4K.
9When you are done, click OK to accept the changes. A dialog box
will appear asking if you would like to restart windows. select the
Restart Now button to restart Windows.
