2.4 Configuring BIOS Settings This section describes how to view and modify the BIOS settings. The Basic Input/Output System (BIOS) has a Setup utility stored in the BIOS flash memory. The Setup utility reports system information and can be used to configure the BIOS settings. The configured data is provided with context-sensitive Help and is stored in the system's battery-backed CMOS RAM. If the configuration stored in the CMOS RAM is invalid, the BIOS settings default to the original state specified at the factory. When the BIOS is started, the first BIOS Setup menu screen is displayed. The BIOS Setup utility contains seven menu screens, which are displayed in this order: Main, Advanced, PCI/PnP, Boot, Security, Chipset, and Exit. ■ Use the left and right arrow keys to move sequentially back and forth through the seven screens (Fields that can be reconfigured are displayed in color. All other fields are nonconfigurable.) ■ Use the up and down arrows, on the keyboard, to scroll through a menu. ■ Use the Tab key to move back and forth across columns. 2.4.1 Changing the Configuration of a BIOS Menu Item You can change the BIOS configuration in several different interfaces: ■ Use a USB keyboard and mouse, and a VGA monitor connected directly to the server. ■ Use the remote video console of the ILOM Service Processor and redirect the server's console output. See Section B.4, "Redirecting Console Output" on page B-3. ■ Use a terminal (or terminal emulator connected to a computer) through the serial port on the back panel of the server. To change the system's parameters: 1. Enter the BIOS Setup utility by pressing the F2 key while the system is performing the power-on self-test (POST). 2. Highlight the field to be modified using the arrow and Tab keys. 3. Press Enter to select the field. A dialog box appears. The box presents you with the options available for the setup field that you have chosen. 2-4 Sun Fire X4500/X4540 Server Service Manual • May 2010
