Again think carefully before answering Y to this question. It's
safe to answer Y if you have the original Windows Sound System card
made by Microsoft or Aztech SG 16 Pro (or NX16 Pro). Also you may
say Y in case your card is NOT among these:

ATI Stereo F/X, AdLib, Audio Excell DSP16, Cardinal DSP16,
Ensoniq SoundScape (and compatibles made by Reveal and Spea),
Gravis Ultrasound, Gravis Ultrasound ACE, Gravis Ultrasound Max,
Gravis Ultrasound with 16 bit option, Logitech Sound Man 16,
Logitech SoundMan Games, Logitech SoundMan Wave, MAD16 Pro (OPTi
82C929), Media Vision Jazz16, MediaTriX AudioTriX Pro, Microsoft
Windows Sound System (MSS/WSS), Mozart (OAK OTI-601), Orchid
SW32, Personal Sound System (PSS), Pro Audio Spectrum 16, Pro
Audio Studio 16, Pro Sonic 16, Roland MPU-401 MIDI interface,
Sound Blaster 1.0, Sound Blaster 16, Sound Blaster 16ASP, Sound
Blaster 2.0, Sound Blaster AWE32, Sound Blaster Pro, TI TM4000M
notebook, ThunderBoard, Turtle Beach Tropez, Yamaha FM
synthesizers (OPL2, OPL3 and OPL4), 6850 UART MIDI Interface.

For cards having native support in VoxWare, consult the card
specific instructions in Documentation/sound/oss/README.OSS.
Some drivers have their own MSS support and saying Y to this option
will cause a conflict.

If you compile the driver into the kernel, you have to add
"ad1848=<io>,<irq>,<dma>,<dma2>[,<type>]" to the kernel command
line.
