Using the Boot Menu programThe Boot Menu program is a built-in configuration program that you can use totemporarily redefine the first startup device without changing settings in theConfiguration/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 the server is started, it returns to the startup sequence that is set inthe Configuration/Setup Utility program.Configuring the Gigabit Ethernet controllerThe Ethernet controller is integrated on the I/O board. It provides an interface forconnecting 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 ports in the server support 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. Fordevice drivers and information about configuring the Ethernet controller, see theBroadcom NetXtreme Gigabit Ethernet Software CD that comes with the server. 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/systems/support/.2. Under Product support, click System x.3. Under Popular links, click Publications lookup.4. From the Product family menu, select System x3850 M2 or System x3950 M2and click Continue.Using the baseboard management controller utility programsUse the baseboard management controller utility programs to configure thebaseboard management controller, update baseboard management controllerfirmware, and remotely manage a server.Using the configuration utility programUse the baseboard management controller configuration utility program to view orchange the baseboard management controller configuration settings and to savethe configuration to a file for use on multiple servers. The configuration utility islocated with the baseboard management controller firmware updates on thefirmware update diskette or CD. You can access the configuration utility after thefirmware update is started and completed or stopped before completing.70 IBM System x3850 M2 and System x3950 M2 Types 7141 and 7233: User’s Guide
