keyboard language, and other system features. Figure 3-59 BIOS Setup Main menu Courtesy: Course Technology/Cengage Learning The power menu in BIOS setup allows you to configure automatic power-saving features for your system, such as suspend mode or a sleep state. Figure 3-60 shows a sample power menu. In most situations, it is best to allow the OS to manage power rather than use BIOS settings. You will learn more about power management in Chapter 11. CHANGING THE BOOT SEQUENCE Figures 3-61 and 62 show two examples of a boot menu in BIOS setup. Here, you can set the order in which the system tries to boot from certain devices (called the boot sequence). Most likely when you first install a hard drive or an operating system, you will want to have the BIOS attempt to first boot from a CD and, if no CD is present, turn to the hard drive. After the OS is installed, to prevent accidental boots from a CD or other media, change BIOS setup to boot first from the hard drive.

CHAPTER 3 152 All About Motherboards PASSWORD PROTECTION TO BIOS SETUP AND TO THE SYSTEM Access to a computer can be controlled using a startup password , sometimes called a user password or power-on password . If the password has been enabled and set in BIOS setup, the startup BIOS asks for the password during the boot just before the BIOS begins searching for an OS. If the password is entered incorrectly, the boot process terminates. The password is stored in CMOS RAM and is changed by accessing the setup screen. (This password is not the same as the OS password.) Many computers also provide jumpers near the chip holding CMOS RAM; you saw Figure 3-61 American Megatrends BIOS Setup Boot menu Courtesy: Course Technology/Cengage Learning Figure 3-60 BIOS Setup Power menu Courtesy: Course Technology/Cengage Learning A+ 220-702 1.1 A+ 220-702 1.1 4.2 1435487389_ch03_CTP.qxd 7/30/09 5:23 PM Page 152

EXITING THE BIOS SETUP MENUS When you finish, an exit screen such as the one shown in Figure 3-63 gives you various options, such as saving or discarding changes and then exiting the program, restoring default settings, or saving changes and remaining in the program.

CHAPTER 3 154 All About Motherboards CHANGING BIOS SETUP FOR BRAND-NAME COMPUTERS Many brand-name computer manufacturers, such as IBM, Dell, and Gateway, use their own custom-designed setup screens. These screens differ from the ones just shown. For example, Figure 3-64 shows the IBM BIOS Setup main menu for an IBM Thinkpad notebook computer. Under the Config option on the screen, you can configure the network port, serial port, parallel port, PCI bus, USB port, floppy drive, keyboard, display settings, power settings, power alarm, and memory settings.
