               DOS/Windows (Version 1.03F3  SIC Ver.2.00)

                             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. 2.00)



    - 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 V1.03F1 (SIC Ver.2.01):



    - 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 V1.03F2 (SIC Ver. 2.02):



    - Game port is able to work again in the DOS and Windows 3.1

      Environment.

    

    For this V1.03F3 (SIC Ver. 2.03):



    - MIC OUT is enable at AD1845 if specify at mix924.ini.

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 \SOUNDSW 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 SOUNDSW 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:\SOUNDSW\CDSETUP.SYS /T:S /P:340 

                 (assuming SONY CD-ROM)

                 DEVICE=C:\SOUNDSW\SLCD.SYS /D:MSCD000 /B:340



               In AUTOEXEC.BAT:

 

               - PATH=C:\SOUNDSW (appended)

                 SET SOUNDSW=C:\SOUNDSW

                 C:\SOUNDSW\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:\SOUNDSW\CDSETUP.SYS /T:S /P:340 

                 (assuming SONY CD-ROM)

                 DEVICE=C:\SOUNDSW\SLCD.SYS /D:MSCD000 /B:340



               In AUTOEXEC.BAT:

 

                 PATH=C:\SOUNDSW (appended)

                 SET SOUNDSW=C:\SOUNDSW

                 C:\SOUNDSW\SNDINIT /B

                 SET BLASTER=A220 I5 D1 T4



               In DOSSTART.BAT:

 

                 C:\SOUNDSW\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:\SOUNDSW\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.
