MDI Device Driver for National DP83820, Gigabit NIC on SCO OpenServer 5.0.5
===========================================================================

Overview:
=========

This file explains how to build, install and configure the MDI driver. 


Building the Driver Software
============================

	a) Bring up a system which runs SCO OpenServer 5.0.5

	b) Install "SCO OpenServer Development System version 5.1.1A"
	pkg. This pkg is available in SCO OpenServer 5.0.5 CD.

	c) Create a directory /home/nsc/drv and unarchive <xxxxx>.cpio.Z
		# uncompress <xxxxx>.cpio.Z
		# cpio -icVd < <xxxxx>.cpio
	
	d) To build, from /home/nsc/drv issue 
		# make clean
		# make

		make creates Driver.o

Installation and Configuration
==============================

	Manual Installation of the driver 
	---------------------------------

	a) Poweroff your system and install the card in a PCI
	Bus Mastering slot.

	b) Power on the system.

	c) Change the permission of the "lkcfg" and "Driver.o" file and then
	Copy DSP (Driver Software Package) files to
	/var/opt/K/SCO/lli/5.0.5a/ID/dp

		# mkdir -p /var/opt/K/SCO/lli/5.0.5a/ID/dp/AOF
		# cd /home/nsc/drv
		# chmod +x lkcfg Driver.o
		# cp System Master Node Driver.o Space.c lkcfg /var/opt/K/SCO/lli/5.0.5a/ID/dp
		# cp AOF/dp /var/opt/K/SCO/lli/5.0.5a/ID/dp/AOF
		


	Configuring the Driver :
	-----------------------

	a) After installation of the driver, run "netconfig" and add the 
	desired chain. Select,

	Hardware -> Add new LAN Adapter -> National Semiconductor's Gigabit
	Ethernet Adapter DP83820

	b) Choose the appropriate protocol (SCO TCP/IP) .

	c) Fill in TCP/IP Configuration parameters like IP Address,
	NetMask, Domain Name etc..

	d) Netconfig will prompt you for relinking the kernel while
	exiting. Choose Yes for relinking the kernel.

	e) Reboot the system after relinking the kernel.

Packaging of SCO Openserver driver
---------------------------------

Requirements
------------

1. You should install O5ndsampl package which is downloadable from 
   www.sco.com/hdk/testsuites

After installing the O5ndsampl package,
Please refer to the /usr/src/O5hdk/net/README file for the detailed step.

You have to modify the /usr/src/O5hdk/net/Make.inc file for the following 
variables.

PRODDESC=National DP83820 Gigabit Ethernet Adapter
PRODVENDOR=National
DLIST=dp

make floppy will create a custom format volume of the driver package.
