OPTi 82C924 LATEST INFORMATION Windows31/DOS (Version 1.03 ) Windows95/DOS (Version 4.00.10) 10/15/95 Important note: ---------------- !! Please check the package you get first !! 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 - 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. - 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 every time the user leave Windows 95 to real mode dos, the SETSOUND program will be invoked to setup the sound card. This is necessary because Win95 may reset PNP devices H/W resource at Win95 exit time. - Add/Update COMM interface and MODEM resource in SYSTEM.INI of Windows 3.1 when the sound card supports modem. 1.

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.
