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

     ac97(4), audio(4), intro(4), midi(4), pci(4), wss(4)

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.

NAME

     eso -- ESS Technology Solo-1 PCI AudioDrive audio device driver

SYNOPSIS

     eso*   at pci? dev ? function ?
     audio* at audiobus?
     joy*   at eso?
     mpu*   at eso?
     opl*   at eso?

DESCRIPTION

     The eso device driver supports sound cards based on ESS Technology Solo-1 PCI AudioDrive chips (ES1938 and ES1946), e.g. the TerraTec 128i
     PCI card.

DIAGNOSTICS

     eso0: can't map Audio 1 DMA into I/O space  PCI autoconfiguration did not map the first audio channel DMA controller into I/O space at a
     suitable address, and the driver was not able map it by itself.  In that case only playback functionality will be available.

     eso0: reset timeout  The device failed to acknowledge being reset.

     eso0: RDR timeout	The driver timed out reading data from a controller register.

     eso0: WDR timeout	The driver timed out waiting to send a command or writing to a controller register.

HISTORY

     The eso device driver appeared in NetBSD 1.5.  The on-board gameport was first supported in NetBSD 1.6.
