     | DOS Driver for VG4 VL-Bus IDE Controller      	   |
     +=====================================================+

     Your VG4 disk controller needs the device drivers to take the
     advantage of the high performance 32-bit VL-Bus when running under
     assorted operating systems.

     You can use the installation program "VG4.EXE" to install the DOS
     driver and Windows driver automatically(Please refer to the
     VG4 Installation Guide for details). If you want to install
     the drivers by yourself, please follow the procedures below:

     1. Complete the installation steps from (1) to (8) which are described
	in the VG4 Installation Guide and boot to the DOS prompt.

     2. Copy the driver VG4.SYS to your system in the appropriate path.

     3. Add the following statement to your CONFIG.SYS file:

  device=C:\VG4\VG4.SYS [/F] [/W] [/P] [/D0:n or /M0:m]
				  [/D1:n or /M1:m] [/X2]



     The parameters F, W and P define the operating mode, and D0, D1, M0, 
     M1, n, and m define the speed settings of the attached hard drives 
     
     NOTE: Only one speed mode can be specified per VL-IDE device.  Either   
     D or M speed mode should be specified on the individual VL-IDE device, 
     NOT both.  It is possible to define different modes for separate 
     VL-IDE devices.  Example: /D0:d /M0:m is illegal
			       /D0:d /M1:m is legal

     F   : VG4 controller works in the Fast mode (Default operation
	   is in Turbo mode).

     W   : VG4 controller works in the 16-bit data access mode.
	   Certain motherboard CPUs(for example, IBM 486 SLC2) have a 16-bit
	   external data bus and cannot operate in the default 32-bit data
	   access mode.

     P   : VG4 controller works in the Power-Saving-Detection mode.
	   This parameter is used when the IDE drive is not fully compatible
	   with the power saving functions.

     D0  : drive 0 PIO speed setting
     D1  : drive 1 PIO speed setting
     n   : drive speed from 0 to 8, or A
	   0 to 8 : PIO speed level 
	   A : IORDY indicator

     M0  : drive 0 DMA speed setting
     M1  : drive 1 DMA speed setting
     m   : drive speed from 0 to 8
	   0 to 8 : DMA speed level
     
     X2  : Disable ISA-IDE IDE HD support (default: enabled)


     In the Fast(F) mode, the VG4 disk controller supports 32-bit
     VL-Bus I/O access. In Turbo(T) mode, the VG4 not only supports
     32-bit VL-Bus I/O access but also read/write multiple commands. Since
     read/write multiple commands allow the host to access disk data in
     multiple-sector blocks, the Turbo mode will usually be faster.

     Note that not all IDE drives support the read/write multiple commands.
     Usually, you may set your VG4 to run in the Turbo mode. When
     your system is brought up, the driver VG4.SYS will automatically
     issues an Identify Drive command to check if the attached IDE drive(s)
     support the read/write multiple commands. In case your drive(s) does
     not support the read/write multiple commands, the VG4 disk
     controller will automatically be forced to run in the Fast mode.

     Please also note: While some IDE drives may respond to the Identify
     Drive command and confirm its capability to support the read/write
     multiple commands, they may not support the read/write multiple
     commands properly.  In such cases, you will need to specify the
     operating mode as "F" explicitly to ensure reliable operation of such
     IDE drives.

     Example:

     The DOS driver VG4.SYS resides in the root directory of the drive
     C:. If you want your VG4 controller to run in the TURBO mode;
     drive 0 at speed 3 and drive 1 at speed 5. Please add the following
     statement to the file CONFIG.SYS.

     device = c:\VG4.SYS /D0:3 /D1:5

     If your VG4 controller has to run in the Fast mode, the
     statement must be changed to:

     device = c:\VG4.SYS /f /D0:3 /D1:5

     If the DOS driver is installed manually, you might have the following
     three types of prompt messages when you boot up the system.

 (a) HDD 0 setting: FAST  Mode, Speed 5 by DEVICE DRIVER AUTOMATICALLY
     HDD 1 setting: Turbo Mode, DMA Speed 5 by DEVICE DRIVER AUTOMATICALLY

     Where the operating mode and the speed parameter may vary with the hard
     drive(s) attached. This message will be shown when the device driver is
     installed without any user specified parameter and the drive(s)
     attached can be found in the internal speed table of the DOS driver.

 (b) HDD 0 setting: FAST  Mode, Speed 2 by HARDWARE JUMPER SETTING
     HDD 1 setting: Turbo Mode, Speed 2 by HARDWARE JUMPER SETTING


	   +-----------------------------------------------+
	   |                      Notice                   |

	   +-----------------------------------------------+

     Where the operating mode and speed parameter may vary with the hard
     drive(s) attached.  This message will be shown when the HDD(s) can't be
     found in the internal speed table. It might appear when the drive(s)
     are brand new models for phe device driver, or the device driver is
     copied from other PC's hard drive. The Installation Utility stands
     for the VG4.EXE.

 (c) HDD 0 setting: FAST  Mode, Speed 5 by USER DEFINED SETTING

     drive(s) attached. This message will be shown when user defined
     parameter is entered with the DOS device driver. The Installation
     Utility stands for the VG4.EXE.

     Four IDE Drive Note
     -------------------
     1. The DOS Device driver "VG4.SYS" loads and supports the IDE
	hard disks on the secondary ISA-IDE connector. You can connect 
	up to four IDE Hard disk Drives on your VG4.

     2. The Master/Slave drive settings for drives on the ISA-IDE 
	connector are the same as for VL-IDE connector.  There should 
	be only one master and one slave on the ISA-IDE connector.
       
     3. The ROM BIOS on the VG4 controller supports large IDE 
	drives on the VL-IDE (J1) connector ONLY.  

     4. If you would like to connect 3 (or 4) IDE hard disks, make sure the
	DOS driver VG4.SYS in installed. Than you can use the
	EIFDISK.EXE enclosed in the "Drivers and Installation Utilities"
	diskette to partition you 3rd and 4th IDE drives before formatting
	them.
      
     IDE CDROM and other IDE Devices
     --------------------------------
	Other devices such as IDE CDROM and TAPE MUST support IDE ATAPI 
	interface. The drive manufacturer provides software drivers to 
	attach these drives.  
	
	Be sure to configure the proper master/slave drive settings.  On 
	BOTH PRIMARY and SECONDARY connectors, there is one master and one
	slave on EACH connector.
		      
	On either PRIMARY or SECONDARY connector, the other IDE device 
	relies on their supplied drivers.  The VG4.SYS driver does 
	not load support for IDE devices besides IDE hard disks.

	When installed on the PRIMARY connector, set in the Mainboard
	Bios drive type to "not installed" for the other IDE device and 
	when necessary, indicate the parameters IRQ14 PORT 1F0 for the 
	driver installation.
	
	When installed on the SECONDARY connector, indicate IRQ15 and PORT 
	170 for the driver installation.
	


     +=======================================================+
     |    VG4 device driver for Microsoft Windows 3.1 and    |
     |    Windows for Workgroups 3.11                        |
     +=======================================================+

     The file VG4.386 is the Microsoft Windows 3.1 disk driver for the
     VG4 disk controller.

     While Microsoft Windows version 3.1 supports 32-bit disk access, the
     disk data transfer between host and the IDE adapter is still limited
     by the 16-bit ISA bus.  If you want to speed up your hard drives under
     Windows through the 32-bit VL-Bus, you need this driver.  In addition,
     the driver also allows your host to access the disk data through the
     faster "read/write multiple" commands.

     If you choose to install the Windows driver manually, you should
     complete the installation steps from (1) to (8) which are described
     in the VG4 Installation Guide, then follow the steps below:


     1. Copy the driver VG4.386 to your system in the appropriate path.

	It is recommended that the driver VG4.386 be copied to the
	Windows SYSTEM directory.

     2. Check if the following lines exit in the [386Enh] section of your
	SYSTEM.ini file.

	[386Enh]
	32BitDiskAccess=ON
	device=*int13

	If the statements do not exist, add them into the [386Enh] section.
	If the statements exist, but 32BitDiskAccess is set to "OFF", change
	it to "ON".


     3. Delete the "device=*wdctrl" device setting.

	Delete the command line "device=*wdctrl" from the [386Enh] section
	of your SYSTEM.INI file, if it exists.

     4. Install the virtual device "VG4.386".

	Add the following command lines in the [386Enh] section of the
	SYSTEM.INI file:

	device=[drive:][\path\]VG4.386
	DisksAccessMode=[Fast|Turbo] [/W] [/D0:n|/M0:m] [/D1:n|/M1:m]

	The [drive:] and [\path\] point to the directory that contains
	VG4.386 file. Note that the setting must specify the full path
	of the device driver VG4.386.

	The setting of disk_access_mode specifies the disk access mode as
	follows:

	Fast  : VG4 controller works in the Fast mode
	Turbo : VG4 controller works in the Turbo mode
		(default mode)

	W   : VG4 controller works in the 16-bit data access mode.
	      Certain motherboard CPUs(for example, IBM 486 SLC2) have a
	      16-bit external data bus and cannot operate in the default
	      32-bit data access mode.

	D0  : drive 0 PIO speed setting
	D1  : drive 1 PIO speed setting
	n   : drive speed from 0 to 8, or A

	      0 to 8 : PIO speed level(speed 8 is the so-called MODE 3
	      timing
	      A      : IORDY indicator

	M0  : drive 0 DMA speed setting
	M1  : drive 1 DMA speed setting
	m   : drive speed from 0 to 8
	      0 to 8 : DMA speed level

	Note : If no parameter is specified, the VG4 disk
	       controller will be set to run under the default Turbo
	       and 32 bit data access mode.

	In the Fast(F) mode, the VG4 disk controller supports
	32-bit VL-Bus I/O access. In the Turbo(T) mode, the VG4 not
	only supports 32 bit VL-Bus I/O access but also read/write multiple
	commands. Since read/write multiple commands allow the host to
	access disk data in multiple-sector blocks, the Turbo mode will
	usually be faster.

	Note that not all IDE drives support the read/write multiple
	commands. Usually, you may set your VG4 to run in the Turbo
	mode. When your system is brought up, the driver VG4.386 will
	automatically issue an Identify Drive command to check if the
	attached IDE drive(s) support the read/write multiple commands.
	In case your drive(s) does not support the read/write multiple
	commands, the VG4 disk controller will automatically be
	forced to run in the Fast mode.

	Please also note: While some IDE drives may respond to the Identify
	Drive command and confirm its capability to support the read/write
	multiple commands, they may not support the read/write multiple
	commands properly.  In such cases, you will need to specify the
	operating mode as "Fast" explicitly to ensure reliable operation of
	such IDE drives.

     [Note]

     1. If there is a ROM BIOS on the VG4 controller,
	the VG4.386 supports LBA mode only on the VL/IDE (J1) connector
	and when it is set as the primary controller.




     +====================================================+
     | Netware 3.xx & 4.01 disk driver for VG4 Controller |
     +====================================================+

     It's assumed that you are familiar with Netware installation.  If this
     is not the case, please refer to related documents.

     Please follow the steps below to install the driver for Netware 3.10,
     and use VG4311.DSK(VG4401.DSK) instead of VG4310.DSK in the following
     procedure when you are installing Netware 3.11, 3.12 or 4.01.  Note that
     you don't have to load the ISADISK.DSK when you are installing the
     Netware driver for VG4 disk controller.

     1. After you have installed the VG4 disk controller, bring up
	the Netware server until the prompt ":" appears on the screen.

     2. Type the following command after the ":" prompt:

	:load VG4310 [/F|/T] [/W] [/D0:n] [/D1:m] port=1f0 int=e

	The parameters F, T and W define the operating mode. The parameters
	D0, n, D1 and m define the speed setting for the attached IDE
	drives.

	F   : VG4 controller works in thd Fast mode (Default
	      operation is in Turbo mode)

	W   : VG4 controller works in the 16-bit data access mode.
	      Certain motherboard CPUs(for example, IBM 486 SLC2) have a
	      16-bit external data bus and cannot operate in the default
	      32-bit data access mode.

	D0  : drive 0 speed setting
	n   : drive 0 speed from 0 to 7

	D1  : drive 1 speed setting
	m   : drive 1 speed from 0 to 7


	Usually, you do not need to enter any speed parameters during the
	installation process. Since when you execute the VG4.EXE to
	install the DOS driver, the device drivers for Netware are also
	reconfigured for the optimal speed setting.

	Note: If no operating mode parameter is specified, the VG4
	      controller will be set to run in the default Turbo and 32 bit
	      data access mode.

	In the Fast(F) mode, the VG4 disk controller supports
	32-bit VL-Bus I/O access. In the Turbo(T) mode, the VG4 not
	only supports 32-bit VL-Bus I/O access but also read/write multiple
	commands. Since read/write multiple commands allow the host to
	access disk data in multiple-sector blocks, the Turbo mode will
	usually be faster.

	Note that not all IDE drives support the read/write multiple
	commands. Usually, you may set your VG4 to run in the Turbo
	mode. When your system is brought up, the driver VG4xxx.DSK will
	automatically issue an Identify Drive command to check if the
	attached IDE drive(s) support the read/write multiple commands. In
	case your drive(s) does not support the read/write multiple
	commands, the VG4 disk controller will automatically be
	forced to run in the Fast mode.

	Please also note: While some IDE drives may respond to the Identify
	Drive command and confirm its capability to support the read/write
	multiple commands, they may not support the read/write multiple
	commands properly.  In such cases, you will need to specify the
	operating mode as "F" explicitly to ensure reliable operation of
	such IDE drives.


     +=============================================+
     | IBM OS/2 2.x disk driver for VG4 Controller |
     +=============================================+

     VG4.ADD is the driver for IBM OS/2 2.0 and IBM OS/2 2.1.

     Your VG4 disk controller needs this device driver to take the
     advantage of the high performance 32-bit VL-Bus when running under
     OS/2.

     Please follow the steps below in installing the driver for the
     VG4 disk controller.

     1. Install the OS/2 driver.

	Copy VG4.ADD to the OS/2 directory of your system.

	Use a text editor to edit the CONFIG.SYS file. Add the following
	line:

	BASEDEV = VG4.ADD [/A:0 [/U:0 /SPEED:n] [/U:1 /SPEED:m]]

	Note: This line must not contain either drive or path information.

	parameters:

	A:       adapter number
	U:       drive number
	SPEED:   drive speed setting
	n:       speed of drive 0 from 0 to 7
	m:       speed of drive 1 from 0 to 7

	Example:

	If you want your VG4 controller to run with drive 0 at
	speed 3 and drive 1 at speed 5.  Please add the following statement
	to the file CONFIG.SYS.

	BASEDEV = VG4.ADD /A:0 /U:0 /SPEED:3 /U:1 /SPEED:5

     2. Delete the "BASEDEV = IBM1S506.ADD" device setting.

	Delete the command line "BASEDEV = IBM1S506.ADD" from the CONFIG.SYS
	file, if it exists.

     [FLOPPY driver installation]

     If you are using Windows NT 3.1 which was shipped from Microsoft before
     February, 1994, there is a floppy driver FLOPPY.SYS under the \FLOPPY
     sub-directory of the Device Driver Diskette. Please browse the
     README.TXT file in the same sub-directory and install the device driver
     as described to avoid the compatibility problem of your floppy drive
     when installing and using the Windows NT 3.1.


     +==============================================+
     |     UNIX Driver for VG4 Disk Controller      |
     +==============================================+

     It is assumed that you are familiar with UNIX installation.  If this
     is not the case, please refer to related documents.

     ********   Install VG4 Controller   ********

     1. Follow the installation step (1) through step (7), as described
	in the Installation Guide, to install the VG4 controller in
	to your system.

     2. Insert a bootable DOS diskette into drive A: and bring up your
	system with DOS.

     3. Insert the diskette "Installation Utility & Drivers" in drive A, and
	execute the installation utility "VG4.EXE".

     4. Choose the "Analyze Hard Drive(s)" function to obtain the optimal
	drive speed(s) and write down these values.

     5. Turn off the system power and set the speed jumper according to the
	data you obtained in step 4.

	Note: When the peed setting parameter you obtained in step 4 is an
	      ODD number, you should set the hardware jumpers with the even
	      number which is one grade lower.

	      For example, if the optimal speed is 5, you should set the
	      hardware speed setting to speed 4 to ensure data security.

	      Should you have two IDE drives attached and the optimal speed
	      settings for these two drives are different, the slower one
	      should be used for hardware jumper setting.

     6. After completing the steps above, you can continue to install the
	UNIX operating system into your hard drive.


     ********     Install UNIX Driver     ********


     This driver is for AT&T UNIX SVR 4.0 and SCO UNIX 3.2.X. The driver is
     provided in another diskette of your VG4 package.
     Please follow the steps below to install the UNIX driver:

     1. Insert the diskette which contains the UNIX Driver into drive A:
	and type the following command after the prompt "#":

	# installpkg

     2. The following message will be shown on the screen:

	Will the VG4 controller be in TURBO or FAST mode
	(T/F)? (default=T)

	Please answer 'T' or 'F' to select the VG4
	operating mode.


     3. Done! You have completed the installation if you are running
	AT&T UNIX SVR 4.0.

     4. If you are running SCO UNIX, type the following commands after the
	driver is installed.

	# cd /
	# shutdown -y -g0 -i6

	The commands will shutdown and reboot your system with the new
	kernel.


     ********    Changing Operating Mode    *******


     If you want to change the operating mode after your system has been
     brought up with the new kernel, please type the following command:

     # ptisetmode

     The following messages will be shown on the screen:

     This command will rebuild the kernel and shutdown the system
     automatically.

     Do you really want to proceed with it (Y/N)? (default=N)


     Please answer 'Y' or 'N'.

     The following message will be shown on the screen to ask you which mode
     will be set:

     Will the VG4 controller be in TURBO or FAST mode
     (T/F)? (default=T)

     Please answer 'T' or 'F' for your setup.


     ******** Removing the Driver ********


     If you want to remove the driver and restore the original hard disk
     device driver, please type the following command after the prompt #:

     # removepkg

     Some installed package name(s) will be shown on the screen. Please
     choose "VG4 UNIX Driver". The removing procedure will continue.

     If you are running the SCO UNIX, please type the following commands to
     shutdown and reboot your system:

     # cd /
     # shutdown -y -g0 -i6
