+.Sh NAME
+.Nm neo
+.Nd NeoMagic MagicMedia 256 audio device driver
+.Sh SYNOPSIS
+.Cd "neo*   at pci? dev ? function ?"
+.Cd "audio* at neo?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the NeoMagic MagicMedia 256AV and 256ZX
+AC'97 audio devices, found on many laptops.
+.Pp
+The MagicMedia 256AV also comes in a variant (usually found on Dell
+and HP laptops) that works in Windows Sound System emulation mode,
+not in AC'97 mode.  That variant of the chip must be used with the
+.Xr wss 4
+driver.  The
+.Nm
+driver will not attach to such chips.
+.Sh BUGS
+The MagicMedia 256 series is not well-documented.
+.Pp
+No MIDI or FM synthesizer capability is provided with the MagicMedia 256
+in AC'97 mode.  While those capabilities are provided by the Windows driver
+for the chip, they are emulated by the Windows driver, and not directly
+supported by the hardware.

+.Xr pci 4 ,
+.Xr wss 4
+.Sh HISTORY
+The
+.Nm
+device driver appeared in
+.Nx 1.5.1 .
