VIASBCFG is a little tool to enable and configure the SBPro feature in compatible VIA chipsets: VT8231 and VT82C686/A/B, where there are no BIOS options available to do so.
(download link at the end of this post).
- Features (current version v0.12d):
- Usage: run VIASBCFG /H to get usage help. But the easy steps are:
- This tool does NOT provide FM/Adlib emulation, so if you need it, you must
run VIAFMTSR after VIASBCFG. (VIAUDIO.COM is not needed).
- This tool may contain bugs. Use at your own risk.
- This tool has been tested successfully with these systems:
- If a game or program crashes trying to play audio, it could be a resource conflict problem. In that case, try to reserve that resources in the BIOS. Change the "Resources controlled by" to "Manual" in BIOS (PnP/PCI section) and change desired IRQ/DMA setting to "Legacy ISA" (some BIOSes) or to "Reserved" (some other BIOSes). If your BIOS does not have that options available, try to configure different IRQ/DMA resources in BLASTER var and re-run VIASBCFG.

VIA chipset detection
Supported VIA southbridges: VT8231, VT82C686/A/B Enable / Disable legacy audio SBPro feature
Optionally Configure resource settings: SB addr, IRQ, DMA, MPU addr, Joyport addr via BLASTER environment variable. If no BLASTER var is found, default settings are: A220 I5 D1 P330 J200 (I7 if HP T5710 is detected).
To disable MPU port, set P0, to disable Joyport, set J0. (for boards without DB15 port)
Set VIA Codec Mixer volume levels (Master, Wave/PCM, FM emulation, Line, CD, Mic, PC-Speaker)
Detection of HP T5710 thin client. When this system is detected, default IRQ value if BLASTER variable is missing, is set to 7 instead of 5 to avoid conflicts with USB controller
(optional) Set BLASTER environment variable with your preferred settings. Example: SET BLASTER=A220 I5 D1 T4 P0 J0
Run VIASBCFG. (optionally set volume levels with /Vxxx options)

Matsonic P3 motherboard with VT82C686B southbridgeEs gibt ein neues Tool welches es VIA Mainboard Besitzern ohne SB Option im BIOS erlaubt DOS Support zu aktivieren.
Damit können nun zahlreiche EPIAs und Thinclients und P3 Mainboards mit Sound unter DOS genutzt werden.
