Notes for DC21X4 NDIS 2 MAC Driver V1.0 for OS/2
==========================================================


This diskette contains the OS/2 driver for Digital EtherWORKS Turbo PCI 
family of Ethernet adapters based on the DC21040 chip.

This version of the driver supports EISA adapters (DE425) only.

Installation
------------

The installation diskette contains the files and directory structure
required to install the driver automatically under Microsoft LAN Manager
for OS/2.  The driver may be installed manually on other OS/2 systems.  To
install the driver, follow the installation instructions for the operating
system being used.

Example OS/2 Server/Client
--------------------------

1. Select Microsoft LAN Manager Setup
2. Select Configuration 
3. Select Network Drivers
4. Select Add New Configuration
5  Select Other Drivers
6. Enter Path A: (this is the default) Select OK
7. Select Digital DC21040-Based Adapters
8. Select specific protocol(s) Select OK
9. The system will now configure, then select OK.

PROTOCOL.INI parameters
-----------------------

Configuration information is passed to the driver using parameters in the
PROTOCOL.INI file.  A stub version of this file, listing the supported
parameters, can be found in the required location on the installation
diskette:
	\MSLANMAN.OS2\DRIVERS\ETHERNET\DC21X4\PROTOCOL.INI

The following PROTOCOL.INI parameters are supported:

	DriverName = DC2104n$
		where n is 0 for the first DC21X4 entry in the
		PROTOCOL.INI, 1 for the second, and so on.

		This parameter must be specified.

	Slot = n
		where n is 16 for the first DC21040-based adapter on the
		PCI bus, 17 for the second, and so on.

		This parameter is optional; if it is not specified, the
		first such adapter is assumed.

A:\MSLANMAN.OS2\README.TXT                                        PAGE 2 of 2

	SIA_Mode = xxx
		where xxx is one of the following:
		TP      for 10BaseT (twisted pair)
		AUI     for 10Base5 (15-pin connector)
		BNC     for 10Base2 (coax connector)

		This parameter is optional; TP is the default.

		When selecting AUI or BNC, insure the shunt jumper on the 
		DE425 is matches the SIA_Mode parameter selected.  See 
		the DE425 Owners Manual for shunt jumper information.

As specified by NDIS 2, a PROTOCOL.INI parameter name (on the left side of
the equals sign) is case-insensitive, but the value (on the right side) is
case-sensitive.


Interrupt Sharing  --  NOT SUPPORTED
------------------------------------

This version of the driver does not support interrupt sharing.  Do not
install a DC21040-based adapter in the same system with another adapter
that uses the same interrupt level.
