  This device driver is distributed on an AS-IS basis to allow
  using the NCS SCSI host adapters with the Microsoft
  Windows NT operating system.  This device driver allows
  connecting not only read-only devices such as CD-ROMs, but
  many other SCSI devices including those with writeable
  media.  While NCS has made an attempt to verify the
  proper operation of the driver, the majority of the testing
  has been with Chinon's CDS-435 and CDS-535 series CD-ROM
  drives.

        The distribution disk is included:

  Installation
  There are two ways to install the NCS SCSI host adapter
  "Miniport" device driver.  If you are setting up Windows NT
  for the first time, you can include the NCS device driver
  during the intial text mode setup.  If you already have
  Windows NT installed, you can use the Windows NT Setup
  application which is normally found in the Main program
  group of the Administrator.

  Text Mode (Initial) Setup
  To install the NCS device driver during the initial, text
  mode setup:
  1. Use the Custom Setup option presented in the second
     screen of the setup process by entering C.
  2. The setup program will scan for any of the standard host
     adapters supported.
  3. You are then given the option to load device drivers from
     a device support disk from an adapter manufacturer.
     Select this option by pressing S.
  4. Highlight:
        Other (Requires disk provided by a hardware
     manufacturer)
     in the list of SCSI Adapters, then press ENTER.
  5. Insert the diskette containing the NCS.SYS device
     driver and associated setup files in the floppy drive you
     are using to begin the Windows NT installation process as
     prompted.  Then press ENTER when ready.
  6. Select:
        NCS-250-SC Host Adapter
     and then press ENTER again.
  7. The device driver will be loaded.  It will scan for any
     NCS host adapters installed on your ISA bus.  If it
     detects one or more NCS SCSI adapters, NCS Host
     Adapter will be added to the list of SCSI Adapters in
     your computer and will be installed in Windows NT.

  Windows NT Setup

  To add the NCS SCSI host adapter device driver to a
  system with Windows NT already installed:
  1. Log on as Administrator.
  2. Run
        Windows NT Setup
     which is normally found in the Main program group.
  3. From the Options menu, select:
        Add/Remove SCSI Adapters...
  4. Click Add... from the SCSI Adapter Setup dialog box.
  5. From the Select SCSI Adapter Option list box, select the
     last entry:
        Other (Requires disk from hardware manufacturer.)
  6. Click Install.
  7. Insert the floppy diskette containing the NCS SCSI
     host adapter device driver and associated setup files.
     Edit the path to the floppy disk drive (if necessary) and
     select OK.
  8. From the Select OEM Option list, highlight:
        NCS-250-SC Host Adapter
     and then select OK. 
        (You need to select "NCS CD-ROM Audio Functions" later, if 
         you have CDS-435, If you have CDS-535, you do not need.)
  9. At the Select SCSI Adapter Option box, select Install to
     install the NCS device driver.
  10.Make sure the path is correct to the floppy disk
     containing your NCS device driver files and then
     choose Continue.
  11.Windows NT Setup will then copy the NCS device driver
     to its system directory and configure the system
     registery to activate the device driver the next time
     Windows NT is started.
  12.If you have CDS-435, select ADD... and continue from #4 to 7 
     above numbers, and select NCS CD-ROM Audio Functions for #8 
     and continue #9.
  13.Select OK to indicate there are no additional SCSI host
     adapter drivers to be installed.
  14.Close the Windows NT Setup application.  It will warn you
     that the device driver you have just added will not be
     activated until the next time you start Windows NT.
  15.Use Ctrl-Alt-Delete to stop Windows NT.  Select Shutdown.
     Then enable Restarting Windows NT after shutdown and
     choose OK.
  16.When Windows NT restarts, the NCS SCSI host adapter
     device driver will be automatically started.
