DESCRIPTION
The
neo driver provides support for the NeoMagic MagicMedia
256AV and 256ZX AC'97 audio devices, found on many laptops.
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
wss(4) driver. The
neo driver will not attach to such chips.

NetBSD
1.5.1.
BUGS
The MagicMedia 256 series is not well-documented.
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.
