The EXM-1 is a high-speed Ethernet and thin Ethernet controller based on
the Intel 82592 controller and 82560 DMA chips.  It provides two
interfaces: a DB-15 DIX/MAU connector for connecting a transceiver cable
to an external Ethernet transceiver, and a BNC connector for connecting
an RG58-type cable for thin Ethernet.

The EXM-1 Ethernet controller is shipped in two configurations: the
EXM1-RB for remote boot and the EXM1-0 for non-remote boot.  Software
provided with the EXM-1 includes a driver for TCP/IP and Novell Netware
(as a client), the EXM-1 configuration program, a diagnostic program for
the EXM-1, the PDSHELL.LAN and PDSHELL.OBJ files (required to create
IPX.COM), and a copy of Novell's Econfig program.  The Econfig program
is included so you can configure workstations to use the Ethernet
(rather than the 802.3) protocol.  If Netware and TCP/IP are to run
concurrently, you must "Econfig" all clients and servers on the network.

Example 1:
	Econfig net$os.exe a:n; b:e 8137

Example 2:
	Econfig ipx.com ipx:e 8137

Individual LAN adapters on a server may be configured for different
protocols.  In example 1, the server for LAN A is configured for 802.3
protocol; the server for LAN B is configured for Ethernet type 8137 (hex).
Example 2 converts a 802.3 IPX driver to Ethernet.

If the network is running the 802.3 protocol, make sure the Protocol bit
in the EXM-1 configuration register is set to 1.  See page 1 of the
EXM-1 Reference for a complete discussion of the protocol options.

This release of the EXM-1 packet driver program, (version 1.05 of
EXM1PD.EXE) allows it to be downloaded by a remote boot PROM.  In order
to boot remotely, a boot image of a DOS boot disk must be created with
the Netware DOSGEN command (see the Netware Supervisors Guide).  An
AUTOEXEC.BAT file on the image disk can be used to load EXM1PD, IPX, and
NET3.

Notes:

o  If multiple shell drivers are to be loaded from the DOS image disk,
   IPX must be the first shell driver installed.

o  If all remote boot workstations cannot boot from identical images, a
   unique boot file must be created for each workstation needing access
   to a different file.  Unique boot ROM options can only be used with
   Netware V2.1x Remote Boot ROMs.

o  The network will time out after about 15 minutes if the IPX driver is
   not loaded.	This can be observed by issuing a DOS DIR command on the
   boot drive after the time-out period has expired and observing that
   the directory is empty.


PROGRAM CHANGES

Version 1.05 of the EXM1PD.EXE program reflects the following changes:

o  IPX need not be loaded before the Network servers issue a broadcast
   message.

o  Interrupt processing has been modified to allow quicker response for
   NetBIOS-based applications.


ORGANIZATION

The following directories contain all the software and firmware used to
support the EXM-1 board:

\	Contains the Brigham Young University's public domain
	implementation of a Novell network driver for packet drivers.
	A Netware IPX.COM built from the object files in this
	directory and used in conjunction with the packet driver
	SYS1PD.EXE and Novell's NET3.COM or NET4.COM constitutes a
	functional Novell client station.

\NCSA	Contains the National Center for Supercomputer Applications'
	public domain Telnet and FTP programs.	These programs work with
	the packet driver added by Clarkson University.  The sources and
	documentation for this application are not included here, but
	are available from Clarkson.  The programs in this directory are
	included as proof that the packet driver supports TCP/IP.
	Commercial TCP/IP packages that use the packet driver can also
	be obtained from FTP Software and The Wollongong Group.
