NAME

     neo -- NeoMagic MagicMedia 256 audio device driver

SYNOPSIS

     neo*   at pci? dev ? function ?
     audio* at audiobus?

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.

SEE ALSO

HISTORY

     The neo device driver appeared in 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.

WSS(4)							   BSD Kernel Interfaces Manual 						    WSS(4)

NAME

     wss -- Windows Sound System hardware audio driver

SYNOPSIS

     wss0   at isa? port 0x530 irq 10 drq 0 drq2 1
     wss0   at isa? port 0x530 irq 10 drq 0 flags 1
     wss*   at acpi?
     wss*   at isapnp?
     wss*   at pnpbios? index ?
     audio* at audiobus?
     opl*   at wss?

DESCRIPTION

     The wss driver supports Microsoft's Windows Sound System, the MAD16 chip based hardware, and their clones.

     The base I/O port is set by a jumper on the board; valid choices are 0x530, 0x604, 0xE80, or 0xF40.  Both IRQ and DMA channels are software
     programmable.  The IRQ may be set to 7, 9, 10, or 11, and the DMA channel may be set to 0, 1, or 3.

     The device flags must have bit 0 (value 1) set to enable the MAD16 support.  This is to avoid potential conflicts with other devices when
     probing the MAD16 because it requires use of extra I/O ports not in the base port range.  Chips needing this flag include the OPTi 82C928,
     82C929, 82C831, and the OAK OTI-601D.  Setting bit 1 (value 2) in flags disables the joystick port on MAD16 hardware.
