Marvell Yukon Ethernet Controller / UPDATE button to update an already 
installed driver for your Marvell Yukon Ethernet Controller. 

NOTE: If you are updating from a driver version which is lower than V6.00, 
you    cannot use the UPDATE button to update the driver. You must first    
remove the installed driver via the CONTROL PANEL / NETWORK /    ADAPTERS / 
Marvell Yukon Ethernet Controller / 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 YUKONWNT driver is
available for download from our web site.

4  Parameters

The YUKONWNT.sys driver supports various advanced options.

 CAUTION: Setting any advanced driver options can dramatically change 
          the behaviour of the driver. This can lead to serious system 
          or network problems. So care must be taken when any driver 
          options are set by the user.

          If the driver is ever misconfigured in such a way that it no 
          longer operates properly, then remove and re-install the driver.
          This causes the default values for all options to be restored.

To set the advanced driver options, proceed as follows:
1.  Start the Registry Editor tool REGEDIT.
2.  All of the driver's options are stored in the system's registry
    database. Open the path to the driver's options:


    Where the 'x' in YUKONWNT must be replaced by the instance
    number of the driver, i.e. YUKONWNT1, YUKONWNT2, etc.
3.  The following actions can be executed:

    - Modify an existing driver option by double-clicking it.
    - Create a new driver option: Select EDIT > NEW, select the type for 
      the new option: "String", "Binary" or "DWORD". The type required 
      by each particular driver option is listed in the "Type:" field in
      the description below.
    - Delete an existing driver option: Select the option to be deleted,
      click EDIT > DELETE. In this case, the driver will use its built-in 
      default for the deleted option.

5.  After you have finished changing the driver options, reboot the 

NOTE: The machine must be rebooted before any changed options can take 

The following is a list of advanced options supported by the YUKONWNT

NOTE: If an advanced option is not present in the registry, you may create
      it via EDIT / NEW. Note that in the absence of any option, the 
      driver will use its built-in default value for that option, as 
      described by "Default value:" below.

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

The parameters supported by the driver are described below.

Bus Type

Registry Name:	"BusNumber"
Default value:    next available adapter found when driver installed
Valid range:      depends on system configuration

This parameter specifies the adapter instance to which the driver shall be 
bound. You can choose from a list of bus/slot combinations for which the 
system has found one or more instances of the Marvell Yukon Ethernet 
When you add, remove,or move any adapters to, from, or between PCI slots,
this list will change.

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 

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.

Jumbo Frame Support

Registry Name:	"MaxFrameSize"
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.

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

Number of Receive Buffers

Registry Name:	"MaxReceives"
Default value:  256 (decimal)
Valid range:    256..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:  256 (decimal)
Valid range:    256..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.

Log Status Messages

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 
- "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.

Connection 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	
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
