MagicMedia 256 audio device driver
neo* at pci? dev ? function ?
audio* at audiobus?
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.
The neo
device driver appeared in
NetBSD 1.5.1.
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.
