2  Required Files
=================

	M4CXNW.LAN	driver
For Client 32 also
	Novell's Client 32 package	
	M4CXNW.LDI	installation script
***


3  Installation
===============

FOR CLIENT 32

Step 1:
Start INSTALL.EXE. Follow the instructions given. Choose "OTHER DRIVERS",
type in the path to the driver directory on the installation medium
(e.g. <drive>:\path\NOVELL\CLIENT32.DOS). Choose your adapter and correct
parameter settings if necessary.

You can change the driver parameters manually by editing the file
STARTNET.BAT in the NetWare Client 32 directory (e.g. C:\NOVELL\CLIENT32.DOS).


FOR NETWARE 3

NOTE:	The setting for MINIMUM PACKET RECEIVE BUFFERS in the STARTUP.NCF must
	be increased by at least 120 per adapter (e.g. for three adapters you
	should add to STARTUP.NCF "SET MINIMUM PACKET RECEIVE BUFFERS=360").

Step 1:
Copy the driver file and any necessary NLM (e.g. any newer ETHERTSM.NLM)
to the NetWare SYSTEM directory.

Step 2:
Load INSTALL.NLM

Step 2a:
Select the "EDIT AUTOEXEC.NCF" option.
Add the following lines to the AUTOEXEC.NCF file

	LOAD [PATH]M4CXNW.LAN ...
	BIND IPX M4CXNW NET=XXX

Step 2b:
Save the AUTOEXEC.NCF file

Step 3:
Restart the server or load the driver manually.

4  Parameters
=============

SLOT = [ 1 .. 65535 ]
	Description:	Defines the slot in which the adapter is installed.
	Help:		If you do not enter a slot number, the driver scans
			automatically for network adapters and prompts the
			slot number in which the network card is found at
			the server console.
	Example:
			LOAD M4CXNW ... SLOT=3 ...

FRAME = [ ETHERNET_802.2 | ETHERNET_II | ETHERNET_SNAP | ETHERNET_802.3 ]
	Description:	Sets the frame type used by the network.
	Help:		The NetWare Server and the Workstations must use
			the same frame type. Otherwise they cannot
			communicate with each other.
	Example:
			LOAD M4CXNW ... FRAME=ETHERNET_II ...

NODE = [ xxxxxxxxxxxx ]
	Description:	Overwrites the network card node address.
	Help:		With this parameter, you can overwrite the default
			node address.
			In a network, every network card must have its own
			unique node address.
			Do not change this address unless you are prepared
			to administer local addresses according to the
			IEEE 802.2 specifications.
			The driver defaults to the node address on the
			board, which corresponds to an undefined override.
	Example:
			LOAD M4CXNW ... NODE=40005A123456 ...

MAXFRAMESIZE = [ 512 .. 9014 ]
	Description:	Set the maximum frame size.
	Help:		The value has to be in the range 512 to 9014.
			The default value is 1514.
			Setting the value above 1514 is only effective if you
			use an ETHERTSM.NLM that supports Jumbo Frames and
			if you load the frame type ETHERNET_II as the first
			frame type on the specific adapter.
			When you change this parameter you should change the
			setting for MAXIMUM PHYSICAL RECEIVE PACKET SIZE in
			your STARTUP.NCF accordingly.
	Example:
			LOAD M4CXNW ... MAXFRAMESIZE=9014 ...

HWCSUM = [ ON | OFF ]
	Description:	Controls hardware checksum offloading
	Help:		By default ON the hardware checksum offload for
			IP/TCP/UDP is enabled. There should be no need to
			disable checksum offload.
			Offloading computation of internet checksums is only
			supported by NetWare 5.x or higher.
	Example:
			LOAD M4CXNW ... HWCSUM=OFF ...

QUIET = [ AUTO | ON | OFF ]
	Description:	Suppress driver status messages.
	Help:		By default AUTO will be used which means that
			status messages will not be suppressed if running on
			a server and will be suppressed if running on a
			client.
			OFF means that messages will not be suppressed.
			ON means that messages will be suppressed.

Auto-negotiation

CONTYPE = [AUTO | 100FD | 100HD | 10FD | 10HD ]
	Description:	Set mode for auto-negotiation, speed duplex-mode.
	Help:		The default value will is AUTO.
	Example:
			LOAD M4CXNW ... CONTYPE=10HD ...

FLOWCTRL = [ ON | OFF ]
	Description:	Enable or disable flow control for the port.
	Help:		This parameter can be used to set the flow control
			capabilities for the port. Using the default setting,
                        the  adapter should automatically detect the 
			capabilities of the peer port. 
	Example:
			LOAD M4CXNW ... FLOWCTRL=OFF ...

Interrupt Moderation (Paced Packet Batch)

Interrupt moderation can be used to decrease the CPU load on systems
with high utilization. But the latency of packets will increase. To
enable interrupt moderation you must specify the mode and the interrupt
rate. The parameters IRQPERSEC and MAXIRQPERSEC are mutual exclusive.

MODERATE = [ NONE | RX | TX | BOTH | ALL ]
	Description:	Interrupt moderation mode.
	Help:		By default, NONE will be used which means interrupt
			moderation is disabled.
			If RX is used only receive interrupts are moderated,
			which means if more than the specified rate of
			interrupts occur they will be congested to reach the
			specified rate. But other interrupts may occur without
			any limitation.
			If TX is specified transmit complete interrupts will
			be moderated.
			BOTH will lead to a moderation of receive and transmit
			interrupts.
			By using ALL, all interrupts will get moderated.

IRQPERSEC = [ 1000 .. 15000 ]
	Desription:	Interrupt rate for static moderation.
	Help:		Independent of the interrupt load only at specified
			intervals interrupts occur. This will increase
			latency of receive or transmit path dependent on
			the mode specified using parameter MODERATE.
			This parameter has a different meaning if used
			together with POLL.
	Example:
			LOAD M4CXNW ... MODERATE=TX IRQPERSEC=5000

MAXIRQPERSEC = [ 1000 .. 15000 ]
	Desription:	Interrupt rate for dynamic moderation.
	Help:		Using dynamic interrupt moderation means that
			interrupt moderation will be enabled only if more
			than the specified number of interrupts occur. The
			measured interrupt rate is not limited to receive
			or transmit interrupts as specified in MODERATE.
			All interrupts will be counted. If more interrupts
			occur the interrupts specified in MODERATE are
			moderated. If the number of interrupts goes down
			below the specified level moderation is disabled.
			Using dynamic interrupt moderation has the
			advantage that the latency is increased only
			if interrupt load is high.
	Example:
			LOAD M4CXNW ... MODERATE=BOTH MAXIRQPERSEC=1000

Other Parameters

Please do not try changing these parameters in a production environment
unless you have figured out that they fit your needs. The changes can
affect the server performance in a postive or negative way. It depends
on the purpose of the server. The default settings of the driver should
meet the requirements of a normal server.

TXCOPYSIZE = [ 0 .. 9018 ]
	Description:	Size of Transmit Copy Buffers.
	Help:		The first fragments of a frame will be copied
			together as long as they fit into this buffer.
			This may lead to a higher transmit throughput
			but it will cost some CPU load. A value of 0
			will disable this feature. The default value
			is 128 on a server and 0 on a client.
			If the driver cannot get physically contiguous memory
			for copy buffers of size 4097 and above, it will not
			load.

POLL
	Description:	Use polling instead of interrupts.
	Help:		In polling mode the adapter will not generate
			interrupts for every received and transmitted
			frame. Interrupts are used for backup purposes
			only. The interrupt rate can be modified using
			parameter IRQPERSEC between 10 and 15000 per
			second (10 by default).
			Polling may be useful if there are multiple
			adapters in the server and interrupts become a
			problem. By default the adapter works in
			interrupt mode.

TXDESC1 = [ 20 .. 200 ]
	Description:	Number of transmit descriptors used.
	Help:		It may be useful to decrease this value if there
			is not enough memory in the server. The default
			value is 100 on a server and 40 on a client.

RXDESC1 = [ 10 .. 200 ]
	Description:	Number of receive descriptors used.
	Help:		It may be useful to decrease this value if there
			is not enough memory in the server. The default
			value is 100 on a server and 20 on a client.

HWCSUMCAP = [ 00 .. FF ]
	Description:	Limit the capabilities for hardware IP/TCP/UDP
			checksum offload.
	Help:		It is possible to disable specific checksum offload
			capabilities. The parameter specifies the allowed
			checksum offload capabilities for the adapter. It
			is in hexadecimal format and you have to add the
			values for the desired capabilities. The default
			value is FF.
			00: Checksum offload not supported
			01: TCP checksum verification (RX)
			02: UDP checksum verification (RX)
			04: IP checksum verification (RX)
			10: TCP checksum generation (TX)
			20: UDP checksum generation (TX)
			FF: all checksum offloads the adapter can support
	Example:
			LOAD M4CXNW ... HWCSUMCAP=7 ...
