I've recently been messing with my 486 pc and have been trying to maximize compatibility and minimize weird bugs across different games.

I usually run this sound card: Shout Out to Media Magic's ISP16 but I'm having problems in some games due to the 48x IDE cd rom drive I have. Before just buying a period accurate drive (I've tried the TEAC_CDI driver with the /S parameter, and CDBQ and they don't work with my drive) I decided to go into the parts bin and pull out my CT1770 SCSI Sound Blaster 16 and give that another go.

So far so good. I'm using a IBM 73H2600 8x cd rom drive. After setting the jumpers correctly (enable termination, ID 1, removed everything else) the main games I seemed to be having CD drive issues with, Night Trap and Phantasmagoria, are working great. Doom works and doesn't seem to get hanging midi notes. King's Quest V is working with midi as well.

But King's Quest VI was giving me problems. I tried the AUDBLAST.DRV that was included in whatever version I have (I believe it's the original KQC box set) and I also tried the updated one from sierrahelp. Speech would stop working after a few samples, the mixer settings would reset and I'd no longer get midi passing through, etc. I tried increasing audioSize, enabling and disabling extra memory, enabling and disabling smartdrv, etc. Nothing helped.

In the installer I noticed that it was giving me a check mark next to the ThunderBoard driver (AUDTHUND.DRV). I figured why not. And it just works! I guess there's some irony in using a driver for a clone card with the real card.

Has anyone else had this experience with trying AUDTHUND instead of AUDBLAST?
