This is a driver for the Guillemot Maxi Studio Isis Soundcard, developed
for NetBSD-current (around 1.6U). It should also work with recent releases
(1.5, 1.6, 1.6.1, 2.0) and is explicitly labelled as experimental. Installation
Instructions are included in the archive.
Bitrot Warning: I haven't used this since ages. The Patch will certainly not apply cleanly to recent NetBSD versions, but fixing it should be quite simple.
