    This document contains information about software drivers installation 
procedure and something user must pay attention to. If you are not familiar   
with DOS and WINDOWS driver installation, you can use the installation program
and read this document at first. The QD6500 drivers version is Ver.2.4.



    A.Introduction
        There are two drivers in the QD6500 diskette: 
          1.QD6500.SYS        DOS enhanced driver
          2.QDICTRL.386       WINDOWS 3.1 or 3.11 enhanced driver

        If there is no EPROM in BIOS socket or on_board BIOS is disabled, DOS
     enhanced driver can be used to improve some disk data transfer 
     performance ( 32_bit access and multiple sectors access). 

    B. Automatic software drivers installation 
        There is an install program in the QD6500 diskette. You can install 
    the drivers as follows:     
      
        1. Insert the diskette in drive A and change drive from C: to A:.
      
        2. Usually, please press: 
                A:INSTALL  <Enter>

        3. You will see the display:
              
                Install DOS Driver  (Y/N)_
          
            If you want to install DOS driver, please type 'Y', otherwise 
            type 'N'.

        4. Then you will be asked:

                Install WINDOWS Driver  (Y/N)_
     
            If you want to install WINDOWS driver, please type 'Y', otherwise 
            type 'N'.
        
        5. You will see:     
                
                Is there any thing you want to change ? (Y/N)_

            If you want to change the above choices, please type 'Y' and 
            input them again, otherwise type 'N' and begin installation.

        6. The drivers will be installed step by step. 
            If you want install WINDOWS driver then the program will check
            whether there is a WINDOWS directory on your hard disk(s).For 
            example, if there is a WINDOWS then you will see:

                Your WINDOWS directory : C:\WINDOWS


                                Press ENTER to accept the input.
                                Press ESC to quit WINDOWS driver installation.

            If you accept the current WINDOWS directory then just press                            
            ENTER. 
            If you want to change the WINDOWS directory by inputting
            the correct directory on your hard disk.

            After installation, please reboot your system.


            This installation program will modify the file CONFIG.SYS of DOS 
        and SYSTEM.INI of WINDOWS. We will preserve their backup files as      
        CONFIG.BAK and SYSTEM.BAK in their correspondent directories.

        If you need on_board BIOS, you can contact with your dealer. 
     
        If you try to use other IDE card, you should uninstall the drivers 
     before you take out QD6500 card. The drivers can be uninstalled 
     as follow:
        
        Insert the QD6500 diskette in drive A and Change drive from C: to A:, 
     then press: 
            A:INSTALL /U <Enter>
        
        The drivers will be uninstalled step by step as the install procedure.

     C. Special case installation
        There are two options of installation program. You can use them in 
     some special cases. the using method is as follows:

            A:Install [/Option1] [/Option2]

    Option1 : 
          S       For slow hard disk, its data transfer rate from 3.8 to 
                  4.4MB/s or higher.
          N1      For normal-1 hard disk, its data transfer rate from 4.4 to   
                  5.0MB/s or higher.
          N2      For normal-2 hard disk, its data transfer rate from 5.0 to
                  6.1MB/s or higher.
          F       For fast hard disk, its data transfer rate is higher than 
                  6.1MB/s.
          U       For uninstall the software driver(s).
          H       For help information.
          W       If the system can not boot up from the disk after the dos 
                  driver installation, you can use this option to try again.

    Option2 : 
          M       For hard disk that supports multiple sectors READ/WRITE.
          O       Forcing driver supports only single sector READ/WRITE.
          NI      Use motherboard BIOS HDD interrupt service routine INT 13H.

  Notes:
      1. Usually the default installation does not need options because the
   driver can configure most of hard disks automatically. If the performance 
   has improved little after the driver installation, you can try to use 
   options for better performance according to your hard disk.
      
      2. /U or /H can only be used without Option2.
     
      3. If there is a item "IDE Block Mode Transfer" in your motherboard 
   BIOS CMOS setup program, you must set it as "Disabled" when you want to
   install DOS or WINDOWS driver because the drivers already use IDE block
   transfer mode. But if you use option /NI to install these drivers, you
   can set the item of motherboard BIOS as "Enabled". At this time, the 
   configuration in the file SYSTEM.INI of WINDOWS is as below:

                    32BitDiskAccess = OFF
                    device = *int13
                    device = QDICTRL.386

      4. If you set LBA mode in motherboard BIOS CMOS SETUP for hard disk 
   drive whose size is great than 528MB, you must FDISK it using the mode. 
   Otherwise, you can not use the mode.

  Warning: 
      1. If you want to use the Option1 to improve performance, you must 
   know that the hard disk transfer rate is higher than the Option1 given, 
   otherwise it can probably lose the data in the hard disk. 

      2. For 486DX-50 CPU, the hard disk transfer rate must be higher than  
   4.0MB/s.   

      3. If you use Windows for Workgroups 3.11, you can not select 32-bit 
   File Access Feature in Virtual Memory of Control Panel for Enhanced 386 
   after you have installed our Windows Driver, because 32-bit File Access 
   Feature uses a different file access method and it conflicts with our 
   Windows driver. Otherwise, you must not install our Windows Driver.

    D. Manual software drivers installation  
        1. DOS enhanced driver installation
            1) Copy QD6500.SYS file to the root directory of primary HDD C:. 
            2) Edit CONFIG.SYS file. Add the following line into CONFIG.SYS:
        
                    DEVICE=C:\QD6500.SYS

                For best results, it should be the first statement in the 
                CONFIG.SYS file. 
            3) Reboot the system.
    
        2. WINDOWS enhanced driver installation
            1) Copy QDICTRL.386 to the subdirectory \WINDOWS\SYSTEM\. 
            2) Edit SYSTEM.INI file under the WINDOWS directory. 
               You will find the following lines under [386Enh] section:
                    
                    32BitDiskAccess = OFF
                    device = *int13
                    device = *wdctrl

                You should modify these three lines to:
                
                    32BitDiskAccess = ON
                    device = *int13
                    device = QDICTRL.386

    E. QDIMARK
          The subdirectory QDIMARK contains a hard disk test program named 
        QDIMARK.EXE. If you want to know more information about it , you can
        read the file QDIMARK.DOC under the subdirectory.
