Peter Wemm 71eed6962e Recognize the CS4326 on the Intel PR440FX motherboard. (It works just like the normal CS4326 except that it's had it's ID's tweaked for some reason) Also mark the device as alive in the attach routine so that the pnp system doesn't think the attach failed.		1997-09-21 03:27:51 +00:00

            --- A new  FreeBSD sound driver ---
            by Luigi Rizzo (luigi@iet.unipi.it)


This is an experimental version of the sound driver for FreeBSD.
I have almost completely rewritten the main parts of the code,
starting from the Voxware 3.5-alpha release with patches from
Amancio Hasty. The only file which is largely similar to the original
ones is "soundcard.h" (for compatibility reasons, since it contains
the definition of all the ioctls).

Visit http://www.iet.unipi.it/~luigi/FreeBSD.html for the latest
information on the drivers.  There you can obtain the latest source
package that includes documentation on the design of the driver.


CARD SUPPORT INFORMATION:

For PnP cards, I also include the vendor_id and serial numbers of
cards I have encountered.

CS4236: PnP id 0x3642630e

    works like a charm. All modes, including full duplex, supported in
    MSS mode.

CS4237: PnP id 0x3742630e

    I had early reports of success with this board, which is almost
    the same as the CS4236.

CS4232: PnP id 0x3242630e

    this chip is reported as broken in the OSS documentation. As a
    matter of fact, on my Intel Zappa motherboard, I have problems in
    make it use the secondary DMA channel. I have it working in
    half duplex (both capture and playback) in SB3.2 emulation,
    and working in playback mode in MSS emulation.

OPTi931: PnP id 0x3109143e

    The data sheets of this chip are very cryptic. I have it working
    in full duplex in all modes _except_ capture of uLAW/ALAW data.
    I am strongly convinced of a bug in the chip. I have sent email
    to OPTI but got no reply so far.  In SB emulation mode the
    driver does not work yet (maybe I do not initialize it the
    right way).

    Another bug seems to affect full duplex operation -- it appears
    that at times DMA transfer are requested but not counted by
    the device. In normal DMA mode this causes deadlocks.  The only
    solution I have found is to fetch the count from the ISA DMA
    registers, but this does not seem to work very well either.

SB16 PnP: PnP id 0xXX008c0e

    There are many such cards (plain SB16 PnP, AWE32, AWE64, Vibra16,
    etc. all differing in the PnP id (and with different synthesis
    devices, which we do not support anyways).

    Since 970903 the driver supports them all, both capture and
    playback, 8 and 16 bits.

GusPnP: PnP id 0x0100561e

    I have code to recognize the board as MSS, but have not tested it
    since I don't own the board. Hopefully someone will test it soon.

OPTI925: PnP id 0x2509143e

    there is code to recognize it as a SB clone. I have reports that
    it probes ok, but not sure if it works.

OPTI930:

    should work as an MSS clone, but support for it is not implemented
    yet.
