    		   INSTALLING BANYAN VINES WITH A DPT PM2022 SCSI CARD

    PROBLEM

    When installing Banyan Vines versions 4.1.1 through 5.54, following the
    directions in the SmartCache III User's Manual, causes the system to fail to
    boot after installation of the operating system.

    CAUSE

    The SmartCache III User's Manual incorrectly states that the SmartCache III
    card should be left at the default settings of IRQ 15 level, and with WD1003
    emulation disabled, in order to install Banyan Vines versions 4.1.1 and later.

    SYSTEMS AFFECTED
    AST PART NUMBER DESCRIPTION

    All AST server systems which use DPT SmartCache III controllers, including
    Premium SE, Premmia SE, and Premmia MTE.

    SOLUTION

    The SmartCache III controller should be configured with the following
    settings through the EISA Configuration Utility, prior to installing Banyan
    Vines:

    WD1003 Emulation:                  Enabled (primary)
    Interrupt Number:                  14 Edge

    If Banyan Vines has already been installed while the card was configured
    incorrectly, it must be reinstalled after the settings have been corrected,
    in order for the system to boot correctly.
