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. By pressing <Del> immediately after switching the system on, or 2. By pressing the <Del> key when the following message appears briefly at the bottom of the screen during the POST (Power On SelfTest). Press DEL to enter SETUP. If the message disappears before you respond and you still wish to enter Setup, restart the system to try again by turning it OFF then ON or pressing the "RESET" button on the system case. You may also restart by simultaneously pressing <Ctrl>, <Alt>, and <Delete> keys. If you do not press the keys at the correct time and the system does not boot, an error message will be displayed and you will again be asked to... PRESS F1 TO CONTINUE, DEL TO ENTER SETUP AR-B1831 22 AR-B1831 User’s Guide 4.3 Using Setup In general, you can use the arrow keys to highlight items, press <Enter> to select, use the PageUp and PageDown keys to change entries, press <F1> for help and press <Esc> to quit. The following table provides more details about how to navigate in the Setup program using the keyboard.

Load Optimized Defaults AR-B1831 34 AR-B1831 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 <Enter> 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. Exit Without Saving Pressing <Enter> on this item asks for confirmation: Quit without saving (Y/N)? Y This allows you to exit Setup without storing in CMOS any change.

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. WATCHDOG TIMER SETTING The watchdog timer is a circuit that maybe be used from your program software to detect crash or hang up. The watchdog timer is automatically disabled after reset. Once you enabled the watchdog timer, your program should trigger the watchdog timer every time before it times out. After you trigger the watchdogtimer, the timer will be set to zero and start to count again. If your program fails to trigger the watchdog timer before times out, it will generate a reset pulse to reset the system or trigger the IRQ9 signal in order to tell your system that the watchdog time is out. User could test watch dog function under ’Debug.exe’ program as follows: WDT Example Description o 2e 87 ;Extended Functions Enable Register o 2e 87 ;Extended Functions Enable Register o 2e 07 ;EFIR=EFER(Extended Function Index Register)point to Logical Device Number Reg. o 2f 08 ;EFDR=EFIR+1, select logical device 8 o 2e 30 ;select CR30 o 2f 01 ;update CR30 with value 01H o 2e f6 ;select CRF6 o 2f 08 ;update CRF6 with value 08H,(8sec reset) g ;go AR-B1831 36 AR-B1831 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. Users could test follow: GPO Example O 2E 87 O 2E 87 O 2E 2A O 2F FC O 2E 07 O 2F 07 O 2E 30 O 2F 01 O 2E F0 O 2F 00 O 2E F2 O 2F 00 O 2E F1 O 2F FF O 2E AA Q GPIO function under ‘Debug.exe’ program
