+.Sh NAME
+.Nm sb
+.Nd Creative Labs Sound Blaster and compatable device driver
+.Sh SYNOPSIS
+For all sound cards supported with the sb driver this is needed:
+.Cd controller snd0
+.Pp
+For the SoundBlaster, SB Pro, SoundBlaster16, or the Pro Audio Spectrum
+  (emulating SB):
+.Cd "device sb0 at isa? port 0x220 irq 7 drq 1 vector sbintr"
+.Pp
+For specific SB16 support:
+.Cd "device sbxvi0 at isa? drq 5"
+.Pp
+For SoundBlaster 16 16 bit MIDI support:
+.Cd "device sbmidi0 at isa? port 0x300"
+.Pp
+To add Jazz16 suport:
+.Cd "options JAZZ16"
+.Pp
+To add support for the Logitech SoundMan Games:
+.Cd "options SM_GAMES"
+.Pp
+To add SG NX Pro mixer support:
+.Cd "options __SGNXPRO__"
+.Pp
+The OPL-2/3 is used in the SoundBlaster, SoundBlaster Pro, SB 16, and the
+Pro Audio Spectrum. For Yamaha OPL-2/OPL-3 FM support:
+.Cd "device opl0  at isa? port 0x388"
+.Sh DESCRIPTION
+This driver covers the SoundBlaster family of cards including the
+SoundBlaster 1.0 to the SoundBlaster 16/SoundBlaster 32.  The awe driver
+provides AWE32/64 functionality.  This driver is provied in FreeBSD
+versions 2.0-current through 3.0-current.  You can also configure more
+then one card on a single DMA using the conflicts keyword in your
+configuration file.  This is useful for boards with more then one type of
+emulation.
+.Sh BUGS
+Since the SB16 uses the same IRQ and addresses for
+the different drivers, some of the snd drivers will not be probed because
+the kernel thinks there is a conflict.  This can be worked-around by
+using the "conflicts" keyword on the sb16's device line.
+.Pp
+Current version doesn't support mode changes without closing and reopening
+the device. Support for this feature may be implemented in a future
+version of this driver.
+.Sh SEE ALSO
+cdcontrol(1),  cdplay(1),  mixer(8)
+.Sh AUTHORS
+The original SoundBlaster DSP and SoundBlaster 16 MIDI, and Yamaha OPL-3  
+drivers were written by Hannu Savolainen.  The SoundBlaster 16 DSP code
+was written by J. Schuber (jsb@sth.ruhr-uni-bochum.de).  Improvments to
+the OPL-3 drivers were made by Rob Hooft (hooft@chem.ruu.nl)
+.Sh HISTORY
+Sound Galaxy NX Pro support added by Hunyue Yau (Jan 6 1994).  MV
+ProSonic/Jazz 16 16bit support added by JRA Gibson (April 1995).  Audio
+Excel DSP 16 support added by Riccardo Facchetti (March 24 1995).
