DQDRIVER, SOFTWARE, IDE/ATAPI Disk Driver Example for OpenVMS Alpha

    DQDRIVER is an IDE disk driver for OpenVMS Alpha.  The driver was 
    originally written and tested on an add-in IDE controller board as well
    as the on-board IDE controller found on the AlphaStation 400 4/233.  

    The driver has been substantially revised to include ATAPI CD-ROM
    support.  In addition, the driver has been incorporated in OpenVMS
    Alpha and is supported on recent 21264 (EV6) based platforms.

    A recent enhancement to DQDRIVER is the inclusion of the IO$_DIAGNOSE
    interface which can be used for CD-ROM audio, or potentially other
    unique ATAPI devices, such as CD-RW.  This enhancement is expected to
    be included in future OpenVMS Alpha releases and in future update
    patch kit for V7.1-2 and V7.2-1.

    The driver is provided as an example, and as with any hardware based
    tools, you should use at your own risk.  The latest version of the
    source code is provide here to update previous release of the code and
    to provide immediate access to CD-ROM audio support.  The driver can be 
    used in an unsupported fashion to access CD-ROM audio until official
    patch kits or new release are available with the new version of the
    driver. 

    A new version of DECW$CDPLAYER been included in the kit.  This version
    contains enhancements for ATAPI CD-ROM audio support via the new
    IO$_DIAGNOSE interface in DQDRIVER.  The new version of the CD player
    can be used to play CD-ROM audio from either ATAPI or SCSI CD-ROM
    drives.  The new version of DECW$CDPLAYER is expected to be include in
    future versions of the DECwindows kit.
