It's been years since I used the kernel oss drivers, but you may need to answer yes to an additional question if you want mpu401 support. You may want to build the sound drivers as modules so that you could experiment with the different parameters w/o having to reboot your computer each time. There are pretty good docs on how to install the supplied sound modules. Again, unless you're planning to use the midi port to connect, say, a midi keyboard, you shouldn't need to worry about the mpu401 interface. Chris
