     | DOS Driver for EIDE2300PLUS VL-Bus IDE Controller	  |
     +============================================================+

     Your EIDE2300PLUS disk controller needs the device drivers to take
     advantage of the high performance 32-bit VL-Bus when running under
     assorted operating systems.

     You can use the installation program "EIDE2300.EXE" to install the DOS
     driver and Windows driver automatically (Please refer to the
     EIDE2300PLUS Installation Guide for details). If you want to install
     the drivers manually, please follow the procedures below:

     1. Complete the installation steps from (1) to (8) which are described
	in the EIDE2300PLUS Installation Guide and boot to a DOS prompt.

     2. Copy the driver EIDE2300.SYS to your system in the appropriate path.

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

       device=C:\EIDE2300\EIDE2300.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	 : EIDE2300PLUS controller works in the Fast mode (Default operation
	   is in Turbo mode).

     W	 : EIDE2300PLUS 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	 : EIDE2300PLUS 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)
           To speed up booting, use this switch if you have no hard
           drives attached to the ISA-IDE channel of the EIDE2300PLUS


     In the Fast(F) mode, the EIDE2300PLUS disk controller supports 32-bit
     VL-Bus I/O access. In Turbo(T) mode, the EIDE2300PLUS 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 EIDE2300PLUS to run in the Turbo mode. When
     your system is brought up, the driver EIDE2300.SYS 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 EIDE2300PLUS 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 EIDE2300.SYS resides in the root directory of drive
     C:. If you want your EIDE2300PLUS 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:\EIDE2300.SYS /D0:3 /D1:5

     If your EIDE2300PLUS controller has to run in the Fast mode, the
     statement must be changed to:

     device = c:\EIDE2300.SYS /f /D0:3 /D1:5

     If the DOS driver is installed manually, you might have one of 
     the following 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 parameters 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		   |
	   |  To optimize the performance of your HDD	   |
	   |	please execute the Installation Utility    |
	   |	 to reconfigure your device driver	   |
	   +-----------------------------------------------+

     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, or the device driver is copied from another 
     PC's hard drive. The Installation Utility stands for EIDE2300.EXE.

 (c) HDD 0 setting: FAST  Mode, Speed 5 by USER DEFINED SETTING
     HDD 1 setting: Turbo Mode, Speed 5 by USER DEFINED SETTING


     Where the operating mode and speed parameters may vary with the hard
     drive(s) attached. This message will be shown when user defined
     parameters are entered with the DOS device driver.

     Four IDE Drives Note
     --------------------
     1. The DOS Device driver "EIDE2300.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 EIDE2300.

     2. The Master/Slave drive settings for drives on the ISA-IDE
	connector are the same as for the VL-IDE connector.  There 
        should be only one master and one slave on the ISA-IDE connector.

     3. The ROM BIOS on the EIDE2300PLUS 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 EIDE2300.SYS is installed. Then you can use the
	EIFDISK.EXE partitioning utility enclosed in the "Drivers and 
        Installation Utilities"	diskette to partition the 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, ATAPI IDE devices are 
        supported by their supplied drivers.  The EIDE2300.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 "Not Installed" for the ATAPI 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.



     [Fast IO driver installation]

     There is a utility COMS.EXE under the \UART\DOS.DRV sub-directory of
     the Device Driver Diskette. Please browse the README.TXT file in the
     same sub-directory and install the utility as described to utilize the
     UART16550 fast IO.

     +============================================================+
     |  EIDE2300PLUS device driver for Microsoft Windows 3.1 and  |
     |  Windows for Workgroups 3.11				  |
     +============================================================+

     The file EIDE2300.386 is the Microsoft Windows 3.1 disk driver for the
     EIDE2300PLUS 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 EIDE2300PLUS Installation Guide, then follow the steps below:


     1. Copy the driver EIDE2300.386 to your system in the appropriate path.

	It is recommended that the driver EIDE2300.386 be copied to the
	Windows SYSTEM directory.

     2. Check if the following lines exist 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 "EIDE2300.386".

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

	device=[drive:][\path\]EIDE2300.386
	DisksAccessMode=[Fast|Turbo] [/W] [/D0:n|/M0:m] [/D1:n|/M1:m]

	The [drive:] and [\path\] point to the directory that contains
	the EIDE2300.386 file. Note that the setting must specify the 
        full path of the device driver EIDE2300.386.

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

	Fast  : EIDE2300PLUS controller works in the Fast mode
	Turbo : EIDE2300PLUS controller works in the Turbo mode
		(default mode)

	W   : EIDE2300PLUS 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
	      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 EIDE2300PLUS disk
	       controller will be set to run under the default Turbo
	       and 32 bit data access mode.

	In the Fast(F) mode, the EIDE2300PLUS disk controller supports
	32-bit VL-Bus I/O access. In the Turbo(T) mode, the EIDE2300PLUS 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 EIDE2300PLUS to run in the Turbo
	mode. When your system is brought up, the driver EIDE2300.386 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 EIDE2300PLUS 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 EIDE2300PLUS controller,
	the EIDE2300.386 supports LBA mode only on the VL/IDE (J1) connector
	and when it is set as the primary controller.



     [Fast IO driver installation]

     NOTE: Normally, it is not necessary to load the the serial drivers 
     described below. Use these drivers only if you experience any 
     difficulties with serial devices attached to your EIDE2300PLUS.           

     If you are using Windows 3.1, there is a device driver COMM.DRV under
     the \UART\WIN.DRV sub-directory of the Device Driver Diskette. Please
     browse the README file in the same sub-directory and install the device
     driver as described.

     If you are using Windows for Workgroups 3.11, there is a device driver
     SERIAL.386 under the \UART\WG.DRV 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.
