OPTi 82C924 LATEST INFORMATION
DOS/Windows (Version 1.03R3 SIC Ver. 2.10A)
02/14/96
Important note:
----------------
Win95/DOS Package:
For the users of the Windows 95, please Install Windows 95
Driver first. Read the README.W95 for the installation guide.
Win31/DOS Package:
For the users of the Windows 3.1x and DOS, please install
this package from a Real DOS prompt. Do not run it in a
Windows' DOS session.
---------------------------------------------------------------------
0. What's NEW in this release v1.03 (SIC Ver. 2.10)
- When DOS CM (Config Manager) isn't present, the program
uses PnP test mode of 82c924 device to setup the hardware
resource in stead of using old-version MC registers.
The WSS mode and SB mode use same IRQ and DMA (SB uses
only the playback DMA channel when the CODEC maybe OK
to support 2 DMA channels for Playback and Capture)
- DOS package now supports both old DOS 6.xx and Win95 DOS
For Win31/DOS package, it works as before. The DOS
Installer will also install Windows 3.1 Drivers.
For Win95/DOS package (a single floppy), it starts
from Win95 installation then brings up DOS Installer.
- Windows 95 Real DOS Support
Add program and functions to integrate with 82C924 Windows
95 driver. SNDINIT program puts SETSOUND in DOSSTART.BAT
when it detects that "winbootdir" is present, so everytime
the user leave Windows 95 to real mode dos, the SETSOUND
program will be invoked to setup the sound card.
- Add/Update COMM interface and MODEM resource in SYSTEM.INI
of Windows 3.1 when the sound card supports modem.
For V1.03R1:
- Fix the problem on Single Mode DMA recording noise
in both CM and non-CM mode.
- Put the correct MIDIMAP file for the 924 MPU401.
For V1.03R2:
- Game port is able to work again in the DOS and Windows 3.1
Environment.
For this V1.03R3 (SIC 2.10A):
- MIC OUT is enable at AD1845 if specify at mix924.ini.
- The default values for LeftMonoInVol and RightMonoInVol are zeros.
This is for the MIC OUT when you specify MONOIN_Src_Name=Mic at
the mix924.ini file.

3. DOS/WINDOWS 3.1 DRIVER INSTALLATION PROCESS
!!! Note: For Windows users, please exit from Windows and run
the installation from DOS. !!!
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:
(Assuming you are using floppy drive A, and you wish to install
to hard disk drive C)
1. Place the disk labeled "OPTi 82C924 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 \OPTI924 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 OPTI924 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:\OPTI924\CDSETUP.SYS /T:S /P:340
(assuming SONY CD-ROM)
DEVICE=C:\OPTI924\SLCD.SYS /D:MSCD000 /B:340
In AUTOEXEC.BAT:
- PATH=C:\OPTI924 (appended)
SET SOUND16=C:\OPTI924
C:\OPTI924\SNDINIT /B
SET BLASTER=A220 I5 D1 T4
In SYSTEM.INI:
- [drivers]
WAVE=SND924.DRV
AUX=SND924.DRV
MIDI=SND924.DRV
MIXER=SND924.DRV
[386Enh]
;OPTi924 COMM interface. Please do not delete/modify
COMxBase=modem IO Port
COMxIrq=modem IRQ
DEVICE=VSND924D.386
[snd16.drv]
SingleModeDMA=YES
CodecType=AD1848
MPU401=YES
MPU401IP=330
MPU401Int=9
IOAddress=530
Interrupt=5
DMADAC=1
DMAADC=1
ModemIO=2E8
ModemIrq=3
* SND924.DRV is the Base driver comprising WAVE, MIDI,
MIXER and AUXILIARY audio services.
* The program only add/update the lines related to modem
when the sound card supports modem.
* VSND924D.386 is the Virtual Device driver for Windows
Enhanced Mode.
* x in the COMxIrq, COMxBase is the COMM number (0-4,
0 means that modem is disabled).
4. WINDOWS 95/DOS DRIVERS PACKAGE INSTALLATION PROCESS
During the installation of 82C924 Windows 95 driver,
the installation program will insert a line in AUTOEXEC.BAT to
invoke the SND4DOS program to install the 924 DOS driver.
After installed the Windows 95 driver, the Windows 95 asks for
a reboot to make the new hardware (in this case, sound device)
to work properly. After reboot, the SND4DOS will be invoked and
bring up the DOS driver installation program (install.com on the
installation disk ) to install the DOS driver and remove the line
SND4DOS inserted in AUTOEXEC.BAT.
Please follow the following procedure to install the software:
1. Follow the installation guideline provided with 924 Windows 95
driver to install the Windows 95 driver.
2. During the first reboot after installed the 924 Windows 95
driver, the program SND4DOS will take over. Just follow the
instrution of SND4DOS to bring OPTi DOS Installer to setup
the Sound Card for your Windows 95 real DOS environment.
!! If you decide not to install at current time, you always
have a chance to re-setup your sound card support for DOS
later. Just type C:\SND4DOS at your Real Mode DOS Prompt.
3. DOS Installer actually is the same one as DOS/Win31.
The differences are
a. it won't install Win31 Drivers and applications.
b. it inserts a line into DOSSTART.BAT in Windows 95
Home Directory.
DOS Installer will modify Windows 95 system files:
In CONFIG.SYS
DEVICE=C:\OPTI924\CDSETUP.SYS /T:S /P:340
(assuming SONY CD-ROM)
DEVICE=C:\OPTI924\SLCD.SYS /D:MSCD000 /B:340
In AUTOEXEC.BAT:
PATH=C:\OPTI924 (appended)
SET SOUND16=C:\OPTI924
C:\OPTI924\SNDINIT /B
SET BLASTER=A220 I5 D1 T4
In DOSSTART.BAT:
C:\OPTI924\SETSOUND
5. GETTING HELP ABOUT SNDINIT.EXE
You can issue the following command to get information
about sndinit.exe:
- SNDINIT /?
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 82C924 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:\OPTI924\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 3.1
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.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
