I).     Windows NT 4.0 Fresh Installation Instructions. 
=======================================================
Follow the instructions in this section if you are performing a fresh
installation of Windows NT 4.0.  You can either install
Windows NT from floppies or CD (Also refer to note 3 for additional details.)
1.      Enter the system bios and set the device boot priority.
        For more information, please refer to your system board's user manual
        for reference.
2.      Save the system configuration and exit system BIOS.
3.      Insert CMD IDE controller.  Refer to Note 2 of this document for detail.
4.      Insert the NT4 installation CD into the CD-ROM drive and reboot.
5.      If you choose to install Windows NT from floppies, insert the Windows
        NT Disk1, also known as boot disk, into the floppy drive for the
        floppy installation.
6.      When you see this message, "Windows NT Setup" screen, press the F6
        function key.
7.      When prompted, select the option S to specify additional device 
8.      Highlight other and press enter.
9.      Put the CMD driver diskette into drive A: and press the 'enter' key.  
10.     The screen displays the adapter driver support on the diskette. The
        "CMD CSA-64xx IDE Driver" is highlighted by default; press enter.
11.     If you want to add additional host adapters, do so at this time by
        repeating step 7 for each  host adapter and insert the manufacturer's
        driver diskette.  Otherwise, Press enter to continue with the Windows
        NT installation.
12.     For the remainder of the installation, please follow the NT SETUP
        screens' instructions.
13.     After NT installation is completed and ready for use, re-insert the  
        CMD's device driver diskette into the floppy drive.  Change to the 
        WINNT directory then copy the CMDCFGNT.EXE file from the floppy disk
        to the " \WINNT\SYSTEM32 " directory.  This file will enable you to 
        fine tuning the CMD IDE chip for optimal performance.


II)     Adding CMD host adapter in an existing Windows NT platform
===============================================================================
Notes:  The CMD driver MUST be installed before switching to CMD IDE 
        controller for existing Windows NT 4.0 system.
===============================================================================
1.      Go to the Control Panel and select the "SCSI Adapters" icon.
2.      Select the "Drivers" tab and click on the "Add" button.
3.      Click on the "Have Disk" button, insert the driver diskette provided
        by CMD.
4.      From the "Install From Disk" dialogue box, type A:\WINNT and
        click ok.
5.      Select the "CMD PCI 646U2/648/649 Ultra DMA IDE Controller" from
        the "SCSI Adapter" screen and click ok.
6.      When prompted to reboot, you must reboot for the new changes to take
        effect.
7.      Shut down the system and install the CMD IDE controller to a PCI bus
        master slot.  Refer to Notes 2 of this README file for reference.
9.      Turn on your system and the NT operating system should be functional
        with the CMD IDE controller .
        (If the system fails with a blue screen with the third line from top
         say "Inaccessible_boot_device," then CMD driver is not properly
         loaded in the previous steps.)  
10.     Reboot NT and try to restart with the last known good configuration
        then go back to step 1 to reinstall the CMD driver again.
        To return to the last know good configuration setting, press the
        Space bar when booting NT and press " L " then RETURN.


III).   Optimize the Controller's performance
=============================================
The following steps are optional, for those who are interested in getting
maximum performance.
1.      Open the CMD configuration utility by performing the following steps:
        a).     Press the START button from the tool bar and select run.
        b).     Type CMDCFGNT.EXE and press ENTER
2.      By the default, the CMD device driver will set the PCI Bus speed to
        33 MHz and the DMA enable button is enabled in the "General Tab"
        option.  If you wish to change to some other values, you can alter
        them in this property page.
3.      The controller #, next tab, (e.g. # = 0, 1,and so on) allows you to
        selectively tune each drive in a channel of a particular CMD
        controller.
        For example:
        ============
        Let's tune secondary channel slave drive to operating at UDMA mode 1.
        Go to the secondary channel override dialogue box, put a check for the
        slave box.  Next, click on the UDMA button.  Then, pull down the menu
        to select 1.  Click OK and reboot the system.

Notes:
======
1.      Install the CMD driver before switching IDE controller for Section
        "II."
2.      Power off the system and connect hard drives and CD-ROM drives to
        the CMD IDE controller.  Install it to the PCI slot that supports bus
        master.  Enter system CMOS setup and clear the hard drives
        configuration to "NONE" or "AUTO."  Also, if the BIOS set up has the
        features for booting from an add-on card, please select it.  SAVE and
        EXIT CMOS.
3.      The current CMD option ROM is not fully functional with the latest 8x0
        chipset to complete a fresh installation of the NT operating system.
        CMD is currently discussing this issue with Intel's support engineers.
        Therefore, if you have the latest Intel 8x0 chipset, please
        follow the section II to add the CMD controller.
