CHAPTER 5 Setup Configuration Utility (SCU) SCU is a program for configuring the BIOS (Base Input/Output System) settings of the computer. BIOS is a layer of software, called firmware, that translates instructions from other layers of software into instructions that the computer hardware can understand. The BIOS settings are needed by your computer to identify the types of installed devices and establish special features. This chapter tells you how to use the SCU program.
When and How to Use the SCU Program When to Use You need to run the SCU program when: ! You see an error message on the screen requesting you to run SETUP. ! You want to restore the factory default settings. ! You want to modify some specific settings according to the hardware. ! You want to modify some specific settings to optimize system performance. Starting SCU NOTE: ! The SETUP screens shown in this chapter are for your reference only. The actual items or settings on your computer may differ.
The menu can be divided into four areas: ! On the top line is the menu bar containing the titles of the available menus. Each menu title brings a specific menu. !
