VIAUDD.SYS VIA Audio Physical Device Driver. 5) DOS Sound (a) General Information: DOS sound can be divided into two classes: 1) Waveform sound,such as a Gun shot, knock sound etc. The "Sound Blaster Pro Compatible sound device" hardware is build-in on VIA VT82C686A/686B/VT8231 south bridge to support DOS Waveform sound and 2) Music sound, which is in MIDI format such as background music. VIA supports a software synthesizer to play MIDI format. (b) In pure DOS environment or "Restart to MS-DOS mode" from Win 9X: How to play a DOS game with both Waveform and MIDI sound. * For Waveform sound: first enable the Sound Blaster setting in the BIOS CMOS setup firstly. Please follow these instructions to enable the setting in the BIOS : INTEGRATED PERIPHERALS -> Onboard Legacy Audio (Enabled) -> Sound Blaster (Disable -> Enabled) * For MIDI music sound: Because the chipset doesn't support MIDI hardware synthesizer the user needs to install VIA software synthesizer TSR utility. This utility can translate MIDI format to Waveform format. To install this utility, please follow this procedure: i) Run "install.exe" in "\DOS" directory. ii) The program will copy the relative files into the directory which you assigned, the default is "C:\VIAUDIO\VIAUDIO.COM". Then the program will insert the new line "C:\VIAUDIO\VIAUDIO.COM" into the AUTOEXEC.BAT and copy the original AUTOEXEC.BAT to AUTOEXEC.VIA. iii) Reboot the system when the installation is completed. iv) You can uninstall this TSR utility by deleting the new line from the AUTOEXEC.BAT and deleting the file C:\VIAUDIO\VIAUDIO.COM (c) In Windows MS-DOS prompt environment: * If you install the VxD audio driver: first enable the Sound Blaster setting in the BIOS CMOS setup firstly. Please follow these instructions to enable the setting in the BIOS : INTEGRATED PERIPHERALS -> Onboard Legacy Audio (Enabled) -> Sound Blaster (Disable -> Enabled) VxD audio driver will trap the I/O port of the SB Pro compitable device to simulate game program I/O access. VIA also supports FM synthesizer driver to play DOS game's MIDI music data. * If you install the WDM audio driver: i) For Waveform sound: In WDM architecture, Microsoft provides a SB Pro enumeration driver, named sbenum.sys, to simulate SBPro behavior for DOS games to play Waveform sound. ii) For MIDI music sound: In WDM architecture, Microsoft provides a WDM kernal driver named swmidi.sys to play MIDI format music. Users should have the setting in DOS games. Wave player is SBPro and Music player is General MIDI. 6) Windows 95/98 (VxD) Driver ************************* ** Driver Installation ** ************************* a) Automatic Installation For Windows 95 and 98, Setup program will automatically install VxD driver.
