Gravis Ultrasound PnP ISA card configuration, how does one do that?

I managed to install NetBSD v1.5
I succeeded in installing the required packages incl. dependencies for KDE
desktop to work.
I even managed to figure out how to get my token-ring card being recognized on
boot-up, but I haven got a clue what, how and where to tell the system to
recognize my sound-card on start-up. It's found when looking for PnP devices but
it says, logically, not-configured.

It would be very nice if I could hear some sounds/music et cetera. ;)
Thx a bundle!
