This driver supports only Windows 2000 (x86). This README file explains how to install the Miniport driver on a machine running Windows 2000 (x86). This YK50X86 NDIS5 Miniport driver cannot be used with other Windows versions than Windows 2000 (x86). *** 2 Required Files ================= To install the driver, the following files are required: YK50X86.sys Marvell Yukon Ethernet Controller NDIS5 Miniport driver YK50X86.inf installation setup script YK50X86.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 2000 (x86) system is able to find, identify, and configure an adapter automatically. If the adapter is not detected during boot by Windows 2000 (x86) the operating system will ask you for the driver. Insert the installation disk and follow the instructions from Windows 2000 (x86). If the adapter is not detected during installation by Windows 2000 (x86) 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 2000 (x86) 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 YK50X86 driver is available for download from our web site. 4 Parameters ============= The YK50X86.sys driver allows you to modify several options in order to optimize the operation of your Marvell Yukon Ethernet Controller. 1. In "Network and Dial-up 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 2000 (x86) 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. 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 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 --------------------------------------------------------------------------- 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 100 802.1p 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. 5 Troubleshooting ================== If you should encounter any problems with your Marvell Yukon Ethernet Controller, please re-read the instructions above and the documentation supplied with the operating system.
