    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 drivers installation, you can use the installation 
program and read this document at first. 
    The QD6580 driver version is Ver.3.6. This version driver adds enhanced 
IDE mode 4 support.


    A.Introduction
	There are four drivers in the QD6580 diskette: 
	    1.QD6580.SYS        DOS enhanced driver
	    2.QDICTRL.386       WINDOWS 3.1 or 3.11 enhanced driver
	    3.QDI1S506.ADD      OS/2 2.1 enhanced driver
	    4.ATDISK.SYS        WINDOWS NT 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 disks data transfer 
	performance ( 32_bit access and multiple sectors access). 

    B. DOS and WINDOWS 3.1x automatic software drivers installation 
	There is an install program in the QD6580 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.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 name 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 QD6580 series card. The drivers 
	       can be uninstalled as follow:
		
	       Insert the QD6580 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
			    6.3MB/s or higher.
	    F       For fast hard disk, its data transfer rate is higher than 
			    6.3MB/s.
	    U       For uninstall the software driver(s).
	    H       For help information.

	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 an 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.

	5. If you install IDE CD-ROM drive on the primary port and it can not
    work after installing DOS driver, you can use option /NI to try again. We
    recommend you to install IDE CD-ROM drive on the second port because the
    connection like this does not affect the hard disk transfer rate on the 
    primary port.

    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.   

				   
    D. Manual software drivers installation  
	1. DOS enhanced driver installation
	    1) Copy QD6580.SYS file to the root directory of primary HDD C:. 
	    2) Edit CONFIG.SYS file. Add the following line into CONFIG.SYS:
									
				DEVICE=C:\QD6580.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

		WARNING: If either of the above lines is not showed in the file 
			 SYSTEM.INI, then you can not add the above lines 
			 into SYSTEM.INI.

	3. OS/2 2.1 enhanced driver installation
	    1) Copy the QDI1S506.ADD into the subdirectory \OS2 of your system.
	    2) Check if the following line exists in the CONFIG.SYS file of 
	       OS/2:
						  
			BaseDev = IBM1S506.ADD
				  
	       If the statement exists, please delete it.
	    3) Add this following statement in your CONFIG.SYS file.

			BaseDev = QDI1S506.ADD 

	    4) Reboot your system.

	4. WINDOWS NT enhanced driver installation
	    1) When you complete WINDOWS NT installation, enter the 
	       subdirectory \WINNT\SYSTEM32\DRIVERS (For WINDOWS NT 3.5, 
	       it may be \WINNT35\SYSTEM32\DRIVERS). There is a file named 
	       ATDISK.SYS in it. Using:

			COPY ATDISK.SYS ATDISK.OLD

	       to preserve it.
	    2) Insert the diskette in drive A and type:

			COPY A:\ATDISK.SYS 

	       to this subdirectory to replace the driver.

	    3) Then shutdown and restart the computer.

    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.
