System Setup Program Overview Use the system setup program as follows: • To change the system configuration information after you add, change, or remove any hardware in your computer • To set or change a user-selectable option such as the user password • To read the current amount of memory or set the type of hard drive installed Before you use the system setup program, it is recommended that you write down the system setup screen information for future reference.
System Setup Program Screens The system setup program screen displays current or changeable configuration information for your computer. Information on the screen is divided into three areas: the options list, active options field, and key functions. Options List — This field appears on the left side of the system setup program window. The field is a scrollable list containing features that define the configuration of your computer, including installed hardware, power conservation, and security features.
System Info System Info Lists system information such as the computer name, and other system-specific information. BIOS Info Shows the BIOS version number and date information. Service Tag Displays computer service tag number for support purposes. CPU Info Identifies whether the computer’s processor supports Hyper-Threading and lists the processor type, processor bus speed, processor ID, clock speed, and L2 cache.
Hard Disk Boot Priority Used to set the device priority of hard drives. The items displayed are dynamically updated according to the hard drives detected. Removable Drives Boot Priority Used to set the device priority of removable devices such a media card readers. The items displayed are dynamically updated according to the removable devices connected.
Load Optimal Defaults Resets CMOS defaults to factory install values. Boot Sequence This feature allows you to change the boot sequence for devices. Option Settings • Diskette Drive — The computer attempts to boot from a floppy drive (if installed). If the floppy disk in the drive is not bootable, if no floppy disk is in the drive, or if there is no floppy drive installed in the computer, the computer generates an error message. • Hard Drive — The computer attempts to boot from the primary hard drive.
3 When F2 = Setup, F12 = Boot Menu appears in the upper-right corner of the screen, press . If you wait too long and the operating system logo appears, continue to wait until you see the Microsoft Windows desktop. Then shut down your computer and try again.
