    AST RESEARCH, INC.        TECHNICAL BULLETIN # 1495           5-23-96

    TITLE: ProStation, Sound Blaster CD-ROM Kit

    SUMMARY

       When the Creative Labs Plug-and-Play (PnP) Value Pack CD-ROM
       drive kit is installed in a ProStation, the CD-ROM may not work.

       This issue applies to the ProStation, AST part number 501759.

    ISSUE

       The Goldstar CD-ROM DOS driver that ships with the Creative Labs
       PnP Value Pack kit may not properly initialize the CD-ROM.

    BACKGROUND

       The DOS driver creates an I/O address and IRQ conflict.

    ACTION

       Goldstar has posted a revision of the driver (GCDR542B.ZIP) in a
       zipped format.  The newer driver configures the hardware to
       I/O address 170 and IRQ 15.

       Download file GCDR542B.ZIP from Goldstar's web site
       (http://www.goldstar.co.kr), unzip it, and run INSTALL.EXE.

    NOTES

       The ProStation switch settings should be set to enable IRQ 15.
       Switch 2 (SW2) is used to select IRQ settings.
       The ProStation ships with all switches in the ON position
       (IRQ disabled).  To enable IRQ 15, set SW2-switch 4 to the OFF
       position.

       For additional information on switch settings, see the
       ProStation User's Manual, AST part number 003273-001A,
       pages 17-19.
