4. Select the startup device.The next time the server is started, it returns to the startup sequence that is set inthe Configuration/Setup Utility program.Enabling the Intel Gigabit Ethernet Boot Agent programThe Intel Gigabit Ethernet Boot Agent is part of the BIOS code. You can use it toconfigure the network as a startable device, and you can customize where thenetwork startup option occurs in the startup sequence. Enable and disable the IntelGigabit Ethernet Boot Agent from the Configuration/Setup Utility program.To enable the Intel Gigabit Ethernet Boot Agent program, complete the followingsteps:1. Turn on the server.2. When the prompt Press F1 for Configuration/Setup Utility is displayed,Press F1.3. From the Configuration/Setup Utility main menu, select Start Options and pressEnter.4. Select Planar Ethernet PXE/DHCP and press the Right Arrow (→) key to set itto Enabled.5. Select Save Settings and press Enter.Configuring the Intel Gigabit Ethernet controllerThe Ethernet controller is integrated on the system board. It provides an interfacefor connecting to a 10 Mbps, 100 Mbps, or 1 Gbps network and provides full duplex(FDX) capability, which enables simultaneous transmission and reception of data onthe network. If the Ethernet port in the server supports auto-negotiation, thecontroller detects the data-transfer rate (10BASE-T, 100BASE-TX, or 1000BASE-T)and duplex mode (full-duplex or half-duplex) of the network and automaticallyoperates at that rate and mode.You do not have to set any jumpers or configure the controller. However, you mustinstall a device driver to enable the operating system to address the controller. Forupdated information about configuring the controller, see the Intel NetworkConnection Software CD that comes with the server. To find updated informationabout configuring the controller, complete the following steps.Note: Changes are made periodically to the IBM Web site.
