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 YUKONWNT NDIS4 Miniport driver cannot be used with other Windows versions than Windows NT4 (x86). *** 2 Required Files ================= To install the driver, the following files are required: YUKONWNT.sys Marvell Yukon Ethernet Controller NDIS4 Miniport driver oemsetup.inf installation setup script GEDIALOG.HLP installation help file GEDIALOG.DLL installation dialogs *** 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. 7. Click OK. 8. Select the Marvell Yukon Ethernet Controller 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 / 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: \HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Services \YUKONWNTx \Parameters 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 machine. NOTE: The machine must be rebooted before any changed options can take effect. The following is a list of advanced options supported by the YUKONWNT driver. 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 Controller. 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 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. 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: 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 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.
