0. <WINNT.3X>: It contains drivers for Windows NT V3.1/V3.5 to support
               " >16MB " system memory that is not supported by AHA 154x
               driver. The following is its content:

        0.1. OEMSETUP.INF: Setup Information File
        0.2. DCSCSI.SYS  : SCSI Driver
        0.3. DCSCSI      : Setup Tag File

             [Before Driver Installation]
             Since your SCSI adapter is AHA 154x driver compatible, the
             operating system would see it as an 154x adapter and
             automatically use AHA 154x driver to work with your adapter when
             installing the operating system. It's O.K. to use AHA 154x driver,
             but not for the environment that equips with system memory over
             16MB. For this case, you must install the driver shipped along
             your adapter to overcome this problem that isn't supported by 154x
             driver. The folloeing are the details for Driver Installation &
             Removal.
