## 1 Overview

    The M4CXNW.LAN driver is a 32-bit ODI HSM Novell NetWare server driver for
    the D-Link DGE-5xx Gigabit Ethernet Adapter.
    The driver complies with the CHSM Driver Specification Version 1.11 from
    January 29, 1998.

## 2 Required Files

    	M4CXNW.LAN	driver
    	M4CXNW.LDI	installation script

## 3 Installation

    NOTE:	The setting for MINIMUM PACKET RECEIVE BUFFERS in the STARTUP.NCF must
    	be increased to at least 120 per adapter (e.g. for three adapters you
    	should add "SET MINIMUM PACKET RECEIVE BUFFERS=360" to STARTUP.NCF).
    	On SMP systems, you may have to multiply this number with the number
    	of active processors.

    If the adapter is installed in the machine NetWare detects the new adapter
    and tries to install a driver. Press <ENTER> to get a list of all available
    drivers and then <INSERT> to install an unlisted driver. Enter the path to
    the driver and select M4CXNW.LAN. Choose Yes to copy the driver to
    the server. NetWare will now install the driver.

    Once the driver has been installed, the adapter parameters or bindings
    can be changed in the AUTOEXEC.NCF file using the NWCONFIG tool.

## 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
