This README file is for the NDIS 2 DOS device driver for Digital Equipment
Corporation's EtherWORKS TURBO EISA Family of adapter(s).
Supported adapters: DE425 

DE425  Adapters use the DC21040.DOS driver.

This README file contains instructions for installing a DE425
Ethernet cards using Real Mode device drivers in a PATHWORKS or Windows 
for Workgroups Network Operating System (NOS) environment.

				DRIVER OPTIONS
				------ -------
	The following options can be added to the corresponding line of
	the CONFIG.SYS file after the driver installation is completed.
	These options will take effect after the next reboot of your
	system.

	EXAMPLE:  DEVICE=C:\DC21040.DOS /P/M/U:DC2104A

	/P
	   The /P option is used to display the information provided by
	   the PROTOCOL.INI file for the given DE525 driver module.
	/M
	    The /M option is used to display memory allocation for the
	    driver.
	/U:Name
	    The /U:Name option specifies the name of the DOS driver.  It
	    is needed when multiple cards (drivers) are specified in the 
	    CONFIG.SYS file.

			  PROTOCOL.INI PARAMETERS
			  ------------ ----------
Mandatory Parameters:  

The mandatory parameters for the DC21040 driver are:


	o DriverName=DC21040$
	
	o Sia_Mode  (range = TP, AUI, TP_FULL_DUPLEX;  default = TP)
	      This parameter defines the cable connection type.

	      - TP selects the RJ45 connector for the twisted pair on-board 
		transceiver, for connection to a twisted pair hub.

	      - AUI selects the AUI mode for external transceiver connection
		to the 15 pin D-sub connector, or the BNC connector.  The 
		selection between these two connectors is done by positioning 
		the shunt jumper on the adapter board.

	      o TP_FULL_DUPLEX specifies Full Duplex operation using the
		twisted pair transceiver.  The adapter should be connected
		to another Ethernet station capable of Full Duplex operation.


                                                                Page 3 of 11
       
Optional Parameters:

	o IRQ   (range = 5,9,11,0  default = 0)
	      This parameter specifies the IRQ level that will be used by
	      the adapter-to-PC interrupt on the bus. Its value must agree
	      with the system configuration. If the value is not specified or
	      0, the level will be taken from the value supplied to the bus
	      Configuration utility.

	o Slot  (range = 1-26,0;  default = 0)
	      This parameter specifies the bus slot where the DE425 
	      adapter is placed.  It is not needed if there is only one 
	      adapter installed in the system.

	      - If SLOT=0 the driver will scan for a DE425 module.  
		The first DE425, adapter will be selected.

	      - A number from 0 to 15 specifies the bus slot position of an
		adapter on the EISA bus:  0 specifies the first EISA bus slot
		(slot 1) on the EISA bus, 1 the second, and so on.

	o NetAddress  (range = 0-FF;  default = n/a)
	      This parameter overrides the address stored in the on-board 
	      Ethernet Address ROM.  For example:

	      NetAddress = 0x01, 0x02, 0x1A, 0xFF, 0x33, 0x2D

		INSTALLATION of the SECOND DE425 DRIVER
		------------ -- --- ------ ------------

	To install an additional DE425 driver in your system, modify
	the PROTOCOL.INI and CONFIG.SYS files.          

	The binding statement must be added to the PROTOCOL.INI as shown. 
	The change to the CONFIG.SYS requires loading the DC21040.DOS 
	driver a second time.

	      o To PROTOCOL.INI:

			[PROTMAN]
			BINDINGS=DC21040$
			BINDINGS=DC2104A$

			[DC21040]
			DRIVERNAME=DC21040$
			SIA_MODE=AUI

			[DC2104A]
			DRIVERNAME=DC2104A$
			SIA_MODE=TP

	      o To CONFIG.SYS:

			DEVICE=C:\DC21040.DOS/U:DC21040$
			DEVICE=C:\DC21040.DOS/U:DC2104A$

		   DE425 DRIVER INSTALLATION for USE WITH PATHWORKS 4.1
		   ----- ------ ------------ --- --- ---- -------------

	Manual Installation

	If PATHWORKS is already installed and configured and you do not wish to 
	use the installation program, perform the following steps manually to 
	install the DE425 NDIS 2 MAC Driver:

	      1. Copy the DC21040.DOS file from the driver installation
		 diskette (A:\NDIS\DOS\DC21040.DOS) to the C:\DECNET directory.

	      2. Add the following line to your CONFIG.SYS to load the
		 driver:

		 DEVICE = C:\DECNET\DC21040.DOS

	      3. ADD the PROTOCOL.INI stub from the driver installation disk
		 to the end of the old PROTOCOL.INI file located in the DECNET
		 directory.  The stub appears as follows:

		 [DC21040]
		 DRIVERNAME=DC21040$
		 SIA_MODE=TP

	      4. Modify the [DATALINK] and [IPX4MAC] sections in the 
		 PROTOCOL.INI file to change the value of the keyword 
		 BINDINGS = driverlabel to BINDINGS = DC21040.DOS


	Automatic Installation Using the PATHWORKS Client Setup Diskettes

	Insert the PWRKS Client Setup diskette 1 of 2 in your floppy disk.

	Run NETSETUP from that drive and follow the instructions until you
	reach the window labeled:       

	Select the network adapter type:

	      o Select "Ethernet" and press ENTER key.

	Select the Ethernet adapter:

	      o Select "Other NDIS" and press ENTER key.

	Enter full DRIVE:\PATH\FILENAME for NDIS driver:

	      o Type A:\NDIS\DOS\DC21040.DOS and press ENTER.

	Enter full DRIVE:\PATH\ for the PROTOCOL.INI stub:

	      o Type A:\NDIS\DOS\ and press ENTER.

	After you have performed these steps, PATHWORKS will copy the 
	corresponding files from the installation diskette to the directory.
