		    INSTALLATION of PCROUTE

    Installation of PCroute consists of essentially three parts.

	1) Setting up the hardware.
	2) Configuring the software.
	3) Testing.

    This section tells you the 'theory' behind the installation 
    process.  See the INSTALL.EXP for an example installation


1) HARDWARE SETUP

	The software assumes that it is being run PC/XT or AT compatible
    with two Western Digital WD8003 (Ethernet or starlan) cards installed.
    It assumes the hardware is configured as follows.

	a) It assumes a floppy disk is installed that it can load
	   the 'pcroute' software as well as the configuration data.

	b) It assumes one of the WD8003 cards is configured so its 
	   control registers start at 280H in I/O space.  This card
	   will be called 'interface 1'.

	c) It assumes the other WD8003 cards is configured so its 
	   control registers start at 2A0H in I/O space.  This card
	   will be called 'interface 2'.

	These are the ONLY assumptions the software makes about the
    hardware it is running on.  In particular the software does not
    use interrupts so it does not care about what IRQ settings on the
    WD8003 boards.   It also does not care how Starlan or Ethernet
    boards are mixed an matched.  Finally it does not use the monitor
    or keyboard so as fare as PCroute is concerned, these do not need
    to be present either.  (you will probably need to have a keyboard, 
    though, because most machines won't boot if it is not present).

2) SOFTWARE SETUP

	This particular version of PCroute gets all its configuration
    data off disk.  It assumes that this data is in a file called
    'pcroute.cfg' in the current directory.  This data needs to be
    in binary format, so a special program called 'config' is used
    to enter/edit this file.  To create/edit this file just type
    'config' at a dos prompt.  The program will prompt you for the
    following information.

	a) The IP address and Network mask for Interface 1
	   (remember interface 1 is the WD8003 board configured
	    with control registers starting at 280H)

	b) The IP address and Network mask for Interface 2

	c) A list of routes.  Each route consists of a network 
	   number (eg 192.26.85.0) and a gateway (eg. 129.105.4.1)
	   the network number 0.0.0.0 is the default route.






    LIMITATIONS:

	PCroute at present has the following (reasonable) restrictions
	on the configuration information.   Note that 'config' does
	not enforce these restrictions, so please obey them.

	1) Network masks must be begin with 255.255  
	2) A maximum of 250 routes can be configured
	3) Only a single default route is allowed.

	
3) RUNNING and TESTING

	Once the WD8003 boards are installed, and connected to
    the networks, and the 'pcroute.cfg' file has been set up, pcroute
    is ready to go.  Just execute 'pcroute'.  Once pcroute is 
    running, try 'pinging' it from some other host on the network.
    If that works, set up the proper routing on your other hosts
    to go through the router and see if it works!!  Note that PCroute
    does not participate in RIP EGP or other dynamic routing protocols.

	Once you have tested that pcroute runs correctly, you
    should create an 'AUTOEXEC.BAT' file that automatically runs
    pcroute when the machine boots.
