If it's similar to Day of the Tentacle, you have to lower the amount of cycles when starting the game for the sound blaster detection to work correctly. Once it's started you can raise the cycles again.

Look for a setting that references "interleaving", you want to reduce the amount of audio (usually measured in ms) stored per chunk so that it ends up getting more evenly spread out.

Running "config -r -resetmapper" from inside DOSBox will delete the saved key mappings and close DOSBox, so when you restart it the keys will be back to defaults. Alternatively if you used the windows installer there is a "Reset KeyMapper" shortcut in the start menu under DOSBox->Options (which is …

Maybe you should consider building this as a device driver instead so it could be loaded from config.sys?

If the IDE interface isn't enabled until the AZTPNP utility runs from autoexec.bat, device drivers in config.sys won't be able to see it because they get loaded before that happens.

It might be that the games are using signed 32-bit values to calculate the free space, so having between 18-20GB free would map to negative values.
