5) DOS Sound (VT82C686A/VT82C686B/VT8231 only)
(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.
