OPTi 82C931 LATEST INFORMATION DOS/Windows (Version 1.02 ) 07/07/96 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 - When Intel's CM (Config Manager) isn't present, the program will check whether the sound card has been configured by the PnP BIOS and if the configuration is good. It may try to get system resource information from the PnP BIOS and assign conflict-free resources to the sound card if it is necessary. In most of the cases the program detects no error during the configuration, so user don't need to do the resource selection. However, if your system doesn't have PnP BIOS, or on your system there is a legacy device, (that is, the PnP BIOS doesn't know what kind of resource it may use) whose resource conflicts with the resource assigned to the sound card, it is necessary that the user involves in choosing the resource for the sound card. The users can always select the resource (Hardware Settings) they prefer by using /S option when there is no Intel's DOS CM loaded. - When Intel's CM (Config Manager) isn't present, the WSS uses dual-DMA as default (that is, when the codec supports dual-DMA and the system has two DMA channels available, the WSS will always use dual-DMA). But by using /S option and choosing single DMA channel can overrule this default. - Windows 3.1x driver gets sound card resource assignment by reading the sound card PnP resources in stead of reading the system.ini file. Should the users make any resource changes, they need to go back to DOS and run SNDINIT (/S). - SNDINIT program will try the best to make sure all hardware settings are good for existing DOS games or applications even if they are not assigned to proper ones by the PNP BIOS or CM at the first. The SNDINIT will give the warning messages on DOS games/applications compatibility if no way to get the right hardware resource. - During the sound card installation (run INSTALL), or configuration (run SNDINIT without /B option), if any warning occurs, the program will display the message on the screen and also save the message in the 931ERR.LOG file. - Add Enhanced full-duplex function at Windows driver. - Add 3D Sound control to the mixer. Need to modify mix931.init at the Windows\system directory. 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 82C931 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 \OPTI931 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 OPTI931 directory and Windows directory respectively. d.) Update your CONFIG.SYS, AUTOEXEC.BAT and SYSTEM.INI files In CONFIG.SYS If you use Philips CD-ROM with the sound card: DEVICE=C:\OPTI931\CDSETUP.SYS /T:I /P:170 /I:15 DEVICE=C:\OPTI931\CR940I.SYS /D:MSCD000 If you don't use a CD-ROM with the sound card: DEVICE=C:\OPTI931\CDSETUP.SYS /T:X In AUTOEXEC.BAT: PATH=C:\OPTI931 (appended) SET SOUND16=C:\OPTI931 C:\OPTI931\SNDINIT /B SET BLASTER=A220 I5 D1 T4 ^ | +------- IO: 0x220, IRQ: 5, DMA: 1 In SYSTEM.INI: - [drivers] WAVE=SND931.DRV AUX=SND931.DRV MIDI=SND931.DRV MIXER=SND931.DRV [386Enh] ;OPTi COMM interface. Please do not delete/modify COMxBase=modem IO Port COMxIrq=modem IRQ DEVICE=VSND931D.386 [snd16.drv] SingleModeDMA=YES * SND931.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. * VSND931D.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 82C931 Windows 95 driver, the installation program will insert a line in AUTOEXEC.BAT to invoke the SND4DOS program to install the 931 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 931 Windows 95 driver to install the Windows 95 driver. 2. During the first reboot after installed the 931 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 If you use Philips CD-ROM with the sound card: DEVICE=C:\OPTI931\CDSETUP.SYS /T:I /P:170 /I:15 DEVICE=C:\OPTI931\CR940I.SYS /D:MSCD000 If you don't use a CD-ROM with the sound card: DEVICE=C:\OPTI931\CDSETUP.SYS /T:X In AUTOEXEC.BAT: PATH=C:\OPTI931 (appended) SET SOUND16=C:\OPTI931 C:\OPTI931\SNDINIT /B SET BLASTER=A220 I5 D1 T4 ^ | +------ IO Port: 0x220, IRQ: 5, DMA: 1 In DOSSTART.BAT: C:\OPTI931\SNDINIT /B 5. SNDINIT.EXE COMMAND OPTIONS You can issue the following command to get the command line options about sndinit.exe: - SNDINIT /? The command options you can use with the SNDINIT are: /b - Setup and initialize the sound card. The program doesn't bring up the graphical user interface to let you select the sound card settings. This is the option normally used. /s - Let the user to select resources. When the system doesn't use Intel's CM, The program uses the resources the PnP BIOS assigns to the sound card if the system has a PnP BIOS. But if you want to overrule the PnP BIOS, use this option and the program will allow you to choose the resources you want to use for the sound card. Once you use this option, your machine will use the settings you chosed ever after. /u - Unlock the resources user selected. This is the reverse option of /S. Once you use this option, you will lose all the settings you chosed by /S, and the program will use resources the PnP BIOS assigned. None - Activate configuration program. Normally you shall use SNDINIT without any option to change the settings of your sound card, like when you change your CD-ROM drive, or you like to disable/enable the game port interface on your sound card, etc.. 6. CD-ROM Interface Setup The CD-ROM Setup Device Driver is CDSETUP.SYS. This driver sets up the CD-ROM interface on the 82C924/925 sound card. Each time you changed or added 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:[/I/X] /P:[addr] /I:[IRQ] [drive] = drive where you have the driver installed [directory] = directory where the driver is located [/I/X] = type of CD-ROM drive I stands for IDE drive X stands for no CD-ROM [address] = Port address for CD-ROM [IRQ] = Interrupt number For example, the following line sets up the interface for a IDE CD-ROM: DEVICE=C:\OPTISND\CDSETUP.SYS /T:I /P:376,170 /I:15 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. Notes for 82C931: ---------------- Normally, the IDE CD-ROM uses IO ports 376h, 170h and IRQ 15. But when the system has a secondary IDE interface on the motherboard, the PnP BIOS may assign resources other than 376h, 170h and IRQ 15 to the IDE interface on the 931 sound card. It is recommanded that the users always connect their CD-ROM drive to the on-board secondary IDE interface when it exists on the system. This is because most of the BIOS or PnP configuration manager favor the secondary IDE interface and allocate the default resources (376, 170, 15) to it, if the user choose to use the IDE interface on the sound card, the DOS IDE CD-ROM driver may not work if the sound card doesn't get default resources. But some BIOS may disable the secondary IDE interface on the motherboard and give the default resources to the IDE interface on the sound card. In this case, the user must install the CD-ROM drive to the IDE interface on the sound card to make the CD-ROM works. However, if you choose to install the IDE CD-ROM to the 931 sound card IDE interface, even though the CD-ROM drive doesn't work in DOS, it may work in Windows 95, if you are lucky, I mean, if you got a good BIOS in your system. You can get two IDE CD-ROMs on your computer. 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
