TxDescriptors= This is to initialize Descriptor resources on the adapter for transmits. Min = 100 Max = 512 Default = 200 RxBuffers= This is to pre-allocate receive ECBs & Receive adapter resources. This setting may be affected by the Netware server maximum/minimum packet receive buffer settings. Min = 32 Max = 512 Default = 200 Speed= This keyword is to force the line speed of the adapter. When this keyword is used, the switch to which the adapter cable is connected must also be forced to the same speed. If not, the adapter and switch may run at different duplex modes. It is important to have the switch and adapter set properly. The best way to ensure good connectivity is to not set the speed keyword andallow for automatic link setup (auto-negotiation). Choices are : AUTO, 10FD,10HD, 100FD, 100HD, Default is Auto. Please note that 1000 Mbs Speed is auto-detected at this time, and cannot be forced. Link= This keyword is set to "AUTO" to allow the adapter to auto-negotiate with a switch using the Speed keyword as an advertised speed upper limit. It is best to allow for auto-negotiation of the card and switch by not setting this keyword or the Speed keyword. Choices are: AUTO, FORCE Default is FORCE. RxTicks= This is to enable the use of a receive "tick" interrupt within a specific time period. Min = 0, disabled Max = 5000000, 5 seconds Units are in micro seconds Default is 300 TxTicks= This is to enable the use of a transmit "tick" threshold interrupt within a specific time period. Min = 0, disabled Max = 5000000, 5 seconds Units are in micro seconds Default is 200 TxPacketsPer= This is to enable the use of allowing an interrupt to occur after a specific amount of packets are transmitted. Min = 0, disabled Max = 100 Default is 20 RxPacketsPer= This is to enable the use of allowing an interrupt to occur after a specific amount of packets are received. Min = 0, disabled Max = 100 Default is 75 CheckSum= This is to enable or disable the transmit & receive checksum off loading feature.The checksum off loading support is only for TCP/IP packets, for that reason it is defaulted to OFF. Choices are: OFF, ON, TX, RX Default is ON TxFlow= This keyword allows enabling/disabling of TxFlow control. Choices are: ON, OFF Default is OFF. RxFlow= This keyword allows enabling/disabling of RxFlow control. Choices are: ON, OFF Default value is OFF. PDriver= Allows for the driver to operate in persistent driver mode. Only use if adapter is placed in a Hot Plug PCI slot and only if required to swap with an exact same board. Choices are: OFF, ON Default value is OFF. NODE= This is a Novell Netware keyword. This keyword will allow an input ethernet node address to replace the adapter factory programmed ethernet node address until a subsequent reboot. Choices are: NODE=nnnnnnnnnnnn FRAME= This is a Novell Netware keyword. String specifying the frame type. Choices are: ETHERNET_II ETHERNET_802.3 ETHERNET_802.2 ETHERNET_SNAP Default is usally ETHERNET_802.2 SLOT= This is a Novell Netware keyword. System-wide unique Hardware Instance Number (HIN) that may be the physical slot number on a slot based bus such as PCI. SLOT=n Jumbo= Keyword to enable Jumbo frame support. When enabled, jumbo packets of up to 9000 bytes are supported. Choices are: Jumbo=ON Default is Jumbo=OFF. P3= This keyword is used when running perform3.exe tests and may increase performance on networks running with many ipx clients. Set P3=1 When running the perform3 test back to back to a single client. Set P3=2 when running the perform3 test with many clients. Default: P3=0. Spuriousfix= When this keyword is set to 1(spurious fix is on), the spurious interrupts count that is sometimes displayed on the Netware console monitor, may be reduced. By setting this keyword to 0 (spurious fix is OFF), performance of the driver may be enhanced. The Default is spurious fix = 1 (spurious fix is on). Choices are: Spuriousfix=0 Spuriousfix=1 (default). Poll= To disable interrupt driven mode in the driver set Poll=1 and the driver will not use interrupts, but will be polled by the Netware OS. This is a common feature supported in NW. The poll mode may increase driver performance in some environments. Choices are: Poll=1 (ON) Poll=0 (OFF) (default). WireSpeed= This feature provides adapter link & data integrity even when attached to a questionable cable and/or switch. For example; an adapter trying to run 1000 speed on a cat3 cable ordinarily would not link. With the WireSpeed=1, the link will occur at 100Mbs. Choices are: WireSpeed=1 (ON) (Default) WireSpeed=0 (OFF). 4.0 WEB Sites and Support Phone Number ________________________________________ IBM Support Web Site: http://www.pc.ibm.com/support IBM Marketing Netfinity Web Site: http://www.pc.ibm.com/netfinity If you have any questions about this update, or problems applying the update go to the following Help Center World Telephone Numbers URL: http://www.pc.ibm.com/qtechinfo/YAST-3P2QLY.html. 5.0 Trademarks and Notices ____________________________ The following terms are trademarks of the IBM Corporation in the United States or other countries or both: IBM NetWare and IntranetWare are registered trademarks of Novell Corporation.
