Configuration and diagnostics 68
Anytime the Configuration Setup Menu is displayed (refer to the "Configuring the Boot Agent in a pre-
boot 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.

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
