2. Under Search technical support, type 7973, 7974, 7975 or 7976 (dependingon the machine type for your server model), and click Search.3. Select the instructions for your operating system.Using the Boot Menu programThe Boot Menu program is a built-in, menu-driven configuration program that youcan use to temporarily redefine the first startup device without changing settings inthe Configuration/Setup Utility program.To use the Boot Menu program, complete the following steps:1. Turn off the server.2. Restart the server.3. Press F12.4. Select the startup device.The next time that the server is started, it returns to the startup sequence that is setin the Configuration/Setup Utility program.Enabling the Broadcom Gigabit Ethernet Utility programThe Broadcom Gigabit Ethernet Utility 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 appears in the startup sequence.To enable the Broadcom Gigabit Ethernet Utility program, complete the followingsteps:1. From the Configuration/Setup Utility main menu, select Devices and I/O Portsand press Enter.2. Select Planar Ethernet and use the Right Arrow (→) key to set it to Enabled.3. Select Save Settings and press Enter.Configuring the Broadcom 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. Tofind updated information about configuring the controller, complete the followingsteps.Note: Changes are made periodically to the IBM Web site. The actual proceduremight vary slightly from what is described in this document.1. Go to http://www.ibm.com/support/.2.
