    MANHATTAN G590 WITH 8150 AND 8100 ERROR 12.35

    PROBLEM

    When one NCR 8150 SCSI controller and one NCR 8100 SCSI controller are
    installed in the Manhattan G590, the system displays the following error
    message at boot:

    "12.35 The computer encountered and error during the autoconfiguration
    process."

    The system continues to boot without any other error messages.

    CAUSE

    The error message is caused by the two different SCSI BIOS configuration
    routines occurring within the system at the same time.  The two controllers
    differ only because the 8100 does not contain an on-board SCSI BIOS, while
    the 8150 does include a SCSI BIOS ROM built onto the board.  In this
    configuration, the 8150 SCSI BIOS loads and is used by both controllers.
    The system BIOS issues the error message to indicate that the computer
    did not configure the 8100 controller.

    There is no reduction in functionality or reliability in this configuration.
    The error message does not indicate any condition that will lead to failures
    or problems with the system.

    SOLUTION

    Because the error message will not lead to any problem or reduction in
    functionality, the error message should be ignored.

    There are no plans to remove this message from the boot-up sequence of
    systems using the above configuration.
