Anytime the Configuration Setup Menu is displayed (refer to the "Configuring the Boot Agent in a preboot PXE or RPL environment" section), you may press the D key to display diagnostics information on the screen. This information can be helpful during interaction with HP Customer Support personnel or your IT team members. After you press the D key, the information remains displayed until you reboot your computer. Actual diagnostics information may vary, depending upon the adapter(s) installed in your computer. Diagnostics information may include the following items: • PWA Number-The Printed Wire Assembly number of the device as stored in the EEPROM • MAC Address-The individual address of the device as stored in the EEPROM • I/O-The I/O address for PCI access determined by the software. On cards without an I/O address, all zeros are displayed • Memory-The memory map PCI access address determined by the software • Slot-The slot number reported by the BIOS. The number displayed is the BIOS version of the PCI slot number. Therefore, actual positions of adapters within slots may not be displayed as expected. Slots are not always enumerated in an obvious manner, and the diagnostics will only report what is indicated by the BIOS. HP NC-Series 31xx Fast Ethernet adapters The following information describes the adapter properties, firmware, and diagnostics available for HP NC-Series 31xx Fast Ethernet adapters through your operating system. Each adapter property displays only if the property is supported by the selected adapter. See the HP Network Configuration Utility online help for the properties available through the NCU. See the Linux readme files for the properties available through the various Linux operating systems. HP NC31xx Fast Ethernet adapter properties for Windows Server 2003 and Windows Server 2003 x64 • 802.1p QoS Packet Tagging. Enables or disables IEEE 802.1p tagging to send network traffic with different priority levels. o Default = Off o Range = Off; On • Coalesce Buffers. Specifies the number of memory buffers available to the driver in case the driver runs out of available map registers. This buffer area is also used when a packet consists of many fragments. If no coalesce buffers or map registers are available, the driver is forced to queue the packet for later transmission. The preferred method of transmitting data is to use map registers, since it is the most efficient method. o Default = 8 o Range = 1-32 • Flow Control Settings. The Flow Control property allows the user to enable or disable the receipt or transmission of PAUSE frames. PAUSE frames enable the adapter and the switch to control the transmit rate. The side that is receiving the PAUSE frame will momentarily stop transmitting. The Configuration and diagnostics 68
