1  Overview
===========

M4CXNT4.sys is the NDIS4 32-bit Miniport driver for the
D-Link DGE-530T Gigabit Ethernet Adapter.

This driver supports only Windows NT4 (x86).
This README file explains how to install the Miniport driver on a machine
running Windows NT4 (x86).

This M4CXNT4 NDIS4 Miniport driver cannot be used with other 
Windows versions than Windows NT4 (x86).

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

3.1  Installing the driver
--------------------------

Read the installation instructions in the adapter manual carefully.
Follow these instructions to install the adapter in your computer.

1.  Start Windows NT4 (x86).
2.  Click START / SETTINGS / CONTROL PANEL / NETWORK.
3.  Select ADAPTERS.
4.  Click ADD.
5.  Select HAVE DISK.
6.  Depending on the type of installation medium used (e.g. CD-ROM, floppy
    diskette, network drive, etc.) enter the path to the required files, 
    e.g.

    D:\

7.  Click OK.
8.  Select the D-Link DGE-530T Gigabit Ethernet Adapter entry that matches 
    your adapter. 
9.  Click OK.
10. Select the appropriate configuration (see section "Driver Options"
    in this readme file for details).

NOTE: We strongly recommend to install the latest Windows NT4 (x86) Service 
Pack    *after* successful installation of the driver. 

11. Click OK.
12. Restart your system.

3.2  Updating the driver
------------------------

You can use the CONTROL PANEL / NETWORK / ADAPTERS / 
D-Link DGE-530T Gigabit Ethernet Adapter / UPDATE button to update an 
already installed 
driver for your D-Link DGE-530T Gigabit Ethernet Adapter.

NOTE: If you are updating from v1.00 of the M4CXNT4 driver, you    cannot 
use the UPDATE button to update the driver. You must first    remove the 
v1.00 driver via the CONTROL PANEL / NETWORK /    ADAPTERS / D-Link DGE-530T 
Gigabit Ethernet Adapter / REMOVE button. 
      Then reboot the computer and install the new driver as described 
      in the section "Installing the driver".



Please note that the latest version of the M4CXNT4 driver is
available for download from our web site:

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


The M4CXNT4.sys driver allows you to modify several options in order to 
optimize the operation of your D-Link DGE-530T Gigabit Ethernet Adapter. 

You can use the CONTROL PANEL / NETWORK / ADAPTERS / 
D-Link DGE-530T Gigabit Ethernet Adapter / PROPERTIES button to configure 
your D-Link DGE-530T Gigabit Ethernet Adapter.

1. In the "Advanced" tag, select the option that you want to change.
2. Enter or choose the desired value in the "Value" box.
3. When finished, click OK .
5. After you have finished changing the driver options, reboot the machine.


The parameters supported by the driver are described below.


Connection Type
---------------

Registry Name:	"ConnectionType_A"
Default value:  0 = "Auto-Sense"
Valid range:    0 = "Auto-Sense"
                11 = "10Mbps Half Duplex"
                12 = "10Mbps Full Duplex"
		13 = "100Mbps Half Duplex"
		14 = "100Mbps Full Duplex"

This parameter contain information regarding autonegotiation, 
duplex capabilities and link speed. The link between Connection type and 
these parameters above mentionated is presented below.

Connection Type		Autonegotiation		DuplexCapabilities		Link Speed
---------------------------------------------------------------------------
AutoSense		On			Half and Full Fuplex		Auto
10Mbps Half Duplex	Off			Half Duplex			10
10Mbps Full Duplex	Off			Full Fuplex			10
100Mbps Half Duplex	Off			Half Duplex			100
100Mbps Full Duplex	Off			Full Fuplex			100


FlowControl
-----------

Registry Name:	"FlowControl_A"
Default value:  1 (On)
Valid range:    0 = "Off"
                1 = "On"

Modes:
- On: Both or only the remote link partner are allowed to send PAUSE frames.

- Off: No link partner is allowed to send PAUSE frames.

NOTE: This parameter is ignored if 'AutoNegotiation' is set to "Off".

This parameter can be used to set the flow control capabilities the port 
reports during auto-negotiation. This parameter can be set for each port 
individually, which is helpful if the port at the other end of the cable 
cannot handle all possible combinations. Using the default setting, the
D-Link DGE-530T Gigabit Ethernet Adapter should automatically detect the 
capabilities of the port.


Network Address
---------------

Registry Name:	"NetworkAddress"
Default value:  burned-in adapter address
Valid range:    0y-00-00-00-00-01 to FE-FF-FF-FF-FF-FF (hexadecimal), 
                where at least the "locally administered" bit 2h 
                (i.e. bit #1) in the 'y' nibble must be set and the 
                multicast" bit 1h (i.e. bit #0) must not be set

CAUTION: Each individual network MAC address can only be used once in a
         network. Assigning the same address to more than one adapter in 
         the same network is not allowed and can cause serious network 
         problems.

To use a network MAC address other than the one burned into the adapter,
enter the network address in the following hexadecimal format:

    XX-XX-XX-XX-XX-XX (e.g. 00-05-5D-93-12-34).

If the network address field blank is left blank (or a different number of
digits is specified), the network address burned into the adapter will 
be used.


Jumbo Frame Support
------------------

Registry Name:	"MaxFrSize"
Default value:  1514 (decimal)
Valid values:   1514 = "Off"
		9014 = "On"

This parameter specifies the frame size that the driver will support. 
The performance of your network usually increases If "Jumbo" frames are 
used. Do not enable this option if you are not sure that your network 
supports jumbo frames.


Number of Receive Buffers
-------------------------

Registry Name:	"MaxReceives"
Default value:  50 (decimal)
Valid range:    3..500 (decimal)

This parameters defines the number of receive buffers allocated by the
driver. If the system does not have enough resources the driver will fail 
to load. Increasing this value may improve performance.


Number of Transmit Buffers
--------------------------

Registry Name:	"MaxTransmits"
Default value:  50 (decimal)
Valid range:    4..200 (decimal)

This parameters defines the number of transmit buffers allocated by the
driver. If the system does not have enough resources the driver will 
fail to load. Increasing this value may improve performance.


5  Troubleshooting
==================

If you should encounter any problems with your
D-Link DGE-530T Gigabit Ethernet Adapter, please re-read
the instructions above and the documentation supplied with the
operating system.

Also refer to your system event log file (using the Event Viewer) and
check it for entries from M4CXNT4.

If your particular problem is not listed or the error persists, please
send your system event log file or at least the event id number and the
logging data (as WORDs) of the entries made by M4CXNT4 to our technical
support.
