I'm trying to get a Thinkpad X20 together for some early windows/late DOS games, and I've run into a snag with getting some Sierra games to work the way I want.
The X20 has a Crystal Semiconductor CS4281 sound chip, which works in DOS, but gives TERRIBLE OPL emulation with chirpy tinny percussion notes, but the WSS (Port 388) FM Wavetable is very nice.
If I start Windows 98 with the VXD Drivers (from the Lenovo website), I get SB DAC working fine in DOS.
If I then change the drivers over to the WDM Win98SE drivers, I KEEP the SB audio, and Windows will enable the FM Wavetable stuff on MIDI, resulting in wonderful music.
Is there any way to get this effect without swapping and re-swapping drivers after each restart?
Here's the datasheet on the chip, if it helps:
