A software synthesizer that plays the MIDI format is supported by VIA. (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: 1) For Waveform sound: First enable the Sound Blaster setting in the BIOS CMOS setup. Then proceed the following instructions to enable the setting in BIOS: INTEGRATED PERIPHERALS -> Onboard Legacy Audio (Enabled) -> Sound Blaster (Disable -> Enabled) 2) For MIDI music sound: Since the chipset does not support MIDI hardware synthesizer, the user needs to install the VIA software synthesizer TSR utility. This utility can transform the MIDI format into Waveform format. To install this utility, please go through the following procedures: i) Run "install.exe" in "\DOS" directory. ii) This program will copy the relative files into the directory assigned by the user, the default is "C:\VIAUDIO\VIAUDIO.COM". The program will then add a new line "C:\VIAUDIO\VIAUDIO.COM" to the AUTOEXEC.BAT, and copy the original AUTOEXEC.BAT to AUTOEXEC.VIA. iii) Reboot the system when the installation is completed. iv) The user can uninstall this TSR utility by removing the new line added to the AUTOEXEC.BAT and deleting the file C:\VIAUDIO\VIAUDIO.COM (c) In Windows MS-DOS prompt environment: If VxD audio driver is installed: First enable the Sound Blaster setting in the BIOS CMOS setup. Then proceed the following instructions to enable the setting in 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 WDM audio driver is installed: i) For Waveform sound: In WDM architecture, Microsoft provides a SB Pro enumeration driver, named sbenum.sys, which is used 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 settings 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. Decompress the zip folder and Type D:> SETUP.EXE (where D equals the location of the setup file) in the run command prompt or double click the setup.exe file. Select "Install driver" option. After the system reboots, the driver will be completely installed. b) Manual Installation Under Device Manager, the "PCI Audio Multimedia Device" will be displayed if the "VIA AC97 PCI (Enhanced) Audio Device" is detected by the PCI enumerator.
