AR-B1851 User’s Guide 4 Award BIOS Setup 4.1 Introduction This chapter discusses the Setup program built into the BIOS. The Setup program allows users to configure the system. This configuration is then stored in battery-backed CMOS RAM so that it retains the Setup information while the power is off. 4.2 Starting Setup The BIOS is immediately active when you turn on the computer. While the BIOS is in control, the Setup program can be activated in one of two ways: 1.

Y Pressing “Y” stores the selections made in the menus in CMOS – a special section of memory that stays on after you turn your system off. The next time you boot your computer, the BIOS configures your system according to the Setup selections stored in CMOS.
AR-B1851 User’s Guide Use this menu to load the BIOS default values that are factory settings for optimal performance system operations. While Award has designed the custom BIOS to maximize performance, the factory has the right to change these defaults to meet their needs. When you press on this item you get a confirmation dialog box with a message similar to: Load Optimized Defaults (Y/N) ? N Pressing ‘Y’ loads the default values that are factory settings for optimal performance system operations.
AR-B1851 User’s Guide Appendix A. Watchdog Timer The WDT(Watch Dog Timer)is used to generate a variety of output signals after a user programmable cont. The WDT is suitable for use in the prevention of system lock-up, such as when software becomes trapped in a deadlock. Under these sort of circumstances, the timer will count to zero and the selected outputs will be driven. Under normal circumstance, the user will restart the WDT at regular intervals before the timer counts to zero.
AR-B1851 User’s Guide Appendix B: Digital I/O One characteristic of digital circuit is its fast response to high or low signal. This kind of response is highly needed for harsh and critical industrial operating environment. Digital Input and Output, generally, are control signals. You can use these signals to control external devices that needs On/Off circuit or TTL devices. You can read or write data to the selected address to enable the function of digital IO.
