    Marvell Yukon Ethernet Controller.

    This driver supports only Windows XP and Server 2003 (X64).
    This README file explains how to install the Miniport driver on a machine
    running Windows XP and Server 2003 (X64).

    This YK51X64 NDIS5.1 Miniport driver cannot be used with other
    Windows versions than Windows XP and Server 2003 (X64).

## 2 Required Files

    To install the driver, the following files are required:
    YK51X64.sys Marvell Yukon Ethernet Controller NDIS5.1 Miniport driver
    YK51X64.inf installation setup script
    YK51X64.CAT digital signature (only if the driver is certified)

## 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.

    With PCI adapters, due to the plug & play facility of PCI, the Windows XP
    and Server 2003 (X64) system is able to find, identify, and configure an
    adapter automatically.

    If the adapter is not detected during boot by Windows XP and Server 2003
    (X64) the operating system will ask you for the driver. Insert the
    installation disk and follow the instructions from Windows XP and Server
    2003 (X64).
    If the adapter is not detected during installation by Windows XP and Server
    2003 (X64) the adapter is installed as "Ethernet Controller" under "Other
    Devices".
    To install the driver you have to perform a driver update as described
    in the next section.

3.2 Updating the driver

    To update the driver, proceed as follows:

    1.  On the desktop right click on MY COMPUTER.
    2.  Select MANAGE.
    3.  In the "Device Manager" select the adapter you wish to update.
    4.  Double click.
    5.  Select DRIVER.
    6.  Click UPDATE DRIVER ... .
    7. Follow the instructions given by Windows XP and Server 2003 (X64) to
    locate the driver.
    8.  If the driver which is found to be the latest is not the one you want
        to install, select the checkbox "Install one of the other drivers".
    9.  Click NEXT.
    10. Select the driver to be installed in the next listbox.
    11. Click NEXT.
        If a message is displayed saying that the driver is not digitally signed
        by Microsoft, click YES.
    12. The message "Windows has finished installing the software for this
        device" is displayed.
    13. Click FINISH to complete the installation.

    Please note that the latest version of the YK51X64 driver is
    available for download from our web site.

## 4 Parameters

    The YK51X64.sys driver allows you to modify several options in order to
    optimize the operation of your Marvell Yukon Ethernet Controller.

    1.  In "Network Connections" right click on the adapter you
        want to configure.
    2.  Select "Properties".
    3.  Click "Configure".
    4.  Click "Advanced".
    5.  In the "Property" box, select the option that you want to change.
    6.  Enter the desired value in the "Value" box.
    7.  When finished, click OK .
     Windows XP and Server 2003 (X64) will reload the driver with the changed
    settings.

    The parameters supported by the driver are described below.

    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 "multicast" bit must not be set
                    (it indicates that the address field contains an
                    individual address)and the "locally administered" bit
                    is set (the address has been assigned by a local
                    administrator). These two bits are first and second
                    bits transmitted on the LAN medium.

    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. 02-00-5A-98-12-34).

    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.

    Maximum Frame Size
    ------------------

    Registry Name:	"MaxFrameSize"
    Default value:  1514 (decimal)
    Valid range:    12..9014 (decimal)

    This parameter specifies the maximum frame size in bytes that the driver
    will support. The performance of your network usually increases when
    a large packet size is used. Do not use values larger than 1514 if you
    are not sure if your network supports jumbo frames.

    Note: For Fast Ethernet adapters the valid range is limited to 1514.

    Hardware Checksumming
    ---------------------

    Registry Name:	"HwChecksum"
    Default value:  1(On)
    Valid values:   1 = "On"
                    0 = "Off"

    This parameter is used to disable the hardware checksum offload for
    TCP/IP. There should be no need to disable checksum offload.

    Wake Up Capabilities
    --------------------

    Registry Name:	"WakeUpModeCap_<n>"	<n> = port designator (A or B)
    Default value:  27 (Magic Packet and Pattern Magic)
    Valid values:   0  = "None"
    		15 = "OS Controlled"
                    25 = "Magic Packet"
                    26 = "Pattern Match"
    		27 = "Magic Packet and Pattern Match"
                    28 = "Link Change"

    - "None"                wake on LAN capabilities are disabled
    - "OS Controlled"	wake up with the default settings
    		 	provided through the OS from Hibernate or Standby
                            state
    - "Magic Packet" 	wake up with MagicPacket from ShutDown state,
    		 	OS Controlled from Hibernate or Standby state
    - "Pattern Match"	wake up with a packet containing a special pattern
    		  	from ShutDown state, OS Controlled from Hibernate
    		  	or Standby state
    - "Magic Packet
       and Pattern Match"	wake up with both from ShutDown state, OS Controlled
    		        from Hibernate or Standby state
    - "Link Change"		wake up with link change from ShutDown state,
    			OS Controlled from Hibernate or Standby state

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

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

    For YukonEC (PCI-Express) family based ethernet controllers the following
    values are used:
    Default value:  256 (decimal)
    Valid range:    128..512 (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)

    For YukonEC (PCI-Express) family based ethernet controllers the following
    values are used:
    Default value:  256 (decimal)
    Valid range:    128..512 (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.

    Interrupt Moderation
    --------------------

    Registry Name:	"Moderate"
    Default value:  1 (On)
    Valid values:   1 = "On"
                    0 = "Off"

    If more than the specified rate of interrupts occur, the function
    Interrupt Moderation groups these interrupts so that several data packets
    can be handled per interrupt. This will lead to lower CPU utilization
    but may increase the latency.

    Max IRQ per Sec
    ---------------

    Registry Name:	"FixedIntMod"
    Default value:  5000 (decimal)
    Valid range:    1000..30000 (decimal)

    This parameter specifies the interrupt rate for Interrupt Moderation. If
    Interrupt Moderation is set to "Off" it will be ignored.

    -------------------

    Registry Name:	"MessageLog"
    Default value:  1 (Status Messages)
    Valid values:   0 = "All Messages"
                    1 = "Status Messages"
                    2 = "Warnings"
                    3 = "Errors"
                    4 = "None"

    This parameter specifies the messages, which are to be logged in the
    Event Log.

    - "All Messages":    This option should only be used for test purposes.
    - "Status Messages": In this mode the driver will generate an event log
                         entry every time the link status changes.
    - "Warnings":        In this mode you will only receive warning or error
                         messages.
    - "Errors":          In this mode you will only receive error messages.
    - "None":            All driver messages will be suppressed. It is not
                         recommended to use this value.

    Media Type
    ---------------

    Registry Name:	"ConnectionType_<n>"  <n> = port designator (A or B)
    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 	Autoneg.	Duplex			Link Speed
    Type				Capabilities
    ---------------------------------------------------------------------------

    100Mbps Half Duplex	Off	Half Duplex		 100
    100Mbps Full Duplex	Off	Full Fuplex		 100

    802.1p Support
    --------------
    Registry Name:	"TagHeaderSupport_<n>" <n> = port designator (A or B)
    Default Value:	0 (Off)
    Valid Values:	0 = "Off"
                    1 = "On"

    This parameter will enable/disable the quality of service for specified
    port. By default this option is not enabled at the first install of
    the driver.

    BatteryModeLinkDetection
    --------------
    Registry Name:	"BatteryModeLinkDetection"
    Default Value:	0 NoEnergySaving
    Valid Values:	0 = NoEnergySaving
                    1 = MaximumEnergySaving
    		4 = EnergyDetect+™

    This parameter will set the mode in which the NIC is working if there
    is no link and the PC is battery-powered.

    NoEnergySaving
    No Energy saving functions are switched on in the NIC.

    MaximumEnergySaving
    The NIC is switched off if there is no link in battery mode. The driver
    wakes up the NIC every 20 seconds to check if there is a new link.

    EnergyDetect+
    If battery-powered the NIC is set to "EnergyDetect+"(TM) mode. The link
    is activated faster than in “MaximumEnergySaving" mode, but the NIC
    requires more power.

    BatterySpeedSettings
    --------------
    Registry Name:	"BatterySpeedSettings"
    Default Value:	3 SmartSpeedDown
    Valid Values:	3 = SmartSpeedDown
                    4 = FullSpeed

    This parameter will sets the Line speed for the NIC if PC is
    battery-powered

    SmartSpeedDown
    If the computer is battery-powered, the NIC speed is switched to
    10/100Mbit/s to reduce the power consumption.

    FullSpeed
    If the computer is battery-powered the NIC is working with maximum
    speed and maximum power consumption.

    If the computer is supplied by AC power all power saving features
    are switched off, and the NIC is working with maximum speed.
